MOTM

I had trouble viewing all of the text on the website.  So here is the
entirety of the MOTM sections...


Synthesis Technology/MOTM.  Paul Schreiber set out to design the \ufffdMOTher of
all Modulars\ufffd (MOTM) when he began Synthesis Technology.  MOTM modules
include top-quality parts throughout and conform to low-noise, audiophile
standards.  For example, the modules have few LEDs in order to remove the
minute amount of noise each LED introduces into the system.

With a simple layout, large knobs, and \ufffd-inch jacks, MOTM modules resemble
Moog modules (see Fig. 13).  However, the modules are designed for high
performance and ultra stability.  The MOTM-320 Voltage Controlled LFO
($229/$149) has four discreet waveshape outputs and a CV input that alters
these waveforms.  The frequency range is from approximately one cycle every
30 minutes to 4 kHz.

Most of the modules are available as complete kits (see Fig. 14), rated on a
scale of 1 to 5 for difficulty.  The Synthesis Technology Web site includes
building tips for people new to DIY.

Besides the MOTM-320, the MOTM system has 13 additional modules:  the
MOTM-300 Ultra VCO ($349/$259); MOTM-120 Sub-Octave Multiplexer ($199/$139);
MOTM-110 VCA/Ring Modulator ($199/$139); MOTM-101 Noise/Sample and Hold
($175/$125); MOTM-410 Triple Resonant Filter ($279/$199); MOTM-420
Voltage-Controlled Filter ($229/$169); MOTM-440 Voltage-Controlled Lowpass
Filter ($269/$199); MOTM-700 Dual Voltage-Controller Router ($189/$139);
MOTM-800 Envelope Generator ($129/$89); MOTM-820 Voltage-Controlled Lag
Processor ($209/$149); MOTM-910 Cascaded Multiple ($99); MOTM-940 Patch
Panel ($89); and the MOTM-130 Dual Pan/Fade VCA ($269/$199).  For an
in-depth review of the MOTM system, see the March 2001 issue of EM.

Yes, odd that that was mentioned but the mixer wasn't - since the 
mixer is closer to production than the dual VCA is.

Paul's original intention was to release to '130 first.  I am sure this was
what he was thinking when he was consulted about the article.  Maybe this
will help speed the release of the '130.

The '130 is on neither the Order page not the News page yet.

Dave--Have you done a mock-up of the 130 yet?  Could you throw one out for
us to nibble on?

Cheers!

Being on this list, it seems odd that EM can announce prices for modules I
know nothing about.

Is there a listing somewhere of all of the upcoming modules and their
descriptions??  The only one I know about is the SEM filter.  Such a list
would be a huge help in planning a system.

First off, you have to understand that article was written in *December*. I
don't think you were on the list then :)

There hasn't been a mock-up done yet, but I will give the info to Moe this
week. I've been busy shipping
out the order backlog and doing assembly work (received an order today for
31 assembled modules! YIKES!!)

The MOTM-130 replaces the MOTM-110, as far as a VCA goes. There are still 31
MOTM-110s left.

The MOTM-130 features:

dual VCAs
Pan/Fade mode
Both Linear and Exponential CV inputs (the first VCA to offer this!!)

It is not on the order form because that is ONLY done when pcb's are sent to
the shop. I am 5 weeks away from
that point.

Also, the reason the article doesn't mention the mixer is that I was going
to do the VCA *first*, but a slow-down
in MOTM-110 orders meant there was a window to slip the Mixer in the flow.

I really could use a few of these!  Now, if they can just keep the 
juice going long enough for the iron to stay hot!  I just think that 
every LFO needs and env and an VCA.... 8-)  And Sync + Env + VCA =

So Paul, perhaps as a gift to all all California power starved brethern you
can do a battery or solar opperated 900 PS ? If you guys dont mindf a really
long entension cord,  we have pleanty of power here in NY! : )

Fair enough, but is there a list of future releases??  All I know about is
the SEM filter (which I plan to buy), and the "micro VCO" whatever the
@#$%* that is!!

Good for you!!

Hopefully, I'll be able to buy one before they sell out.

Is it 1U or 2U??  I'm guessing 2.

That sounds fair.

OK :)

While I'm typing, does Synthesis Technology sell extra motm knobs??

No, but mouser and newark do. they're ELCO and the part # is in the
beginning of every owners manual [less the 900] check www.mouser.com or
www.newark.com

PS: the part number is also in the archives, i know other people and myself
have sent it out before

In December of 2000, Paul estimated the following release order,
subject to change:

a) MOTM-910
b) MOTM-101
c) Mixer
d) Dual VCA
e) VC Pulse Divider
f) Delayed Vibrato
g) Triple Pre-Amp
h) Envelope Follower
i) SEM Filter

But I'm sure Paul can give a better update.

Nice job Moe!  Thanks for taking the time to put that together.

Ivan

My question is about the effects of cable capacitance.  Fred asked about
adding individual outputs to the 120, and Paul S. suggested adding four
op-amps as voltage followers (TL074) so that the taps off the 120 are
looking into a high impedance.  The 820 is advertised as having capacitive
load drivers which I assume is so it can be used to send voltages to other
synths that may be on the other side of the room.   The longest 1/4" cables
I use are 25' feet long.  When adding modifications and building your own
circuits, is that amount of cable capacitance an issue??  Can the outputs
of the UEG, 320, and other motm modules be used to drive other gear when
used with such cables??

THANX!!

January, February, March, done, done, done :)  Way to go, Paul!!

>d) Dual VCA

I'd like a better description of this.  Does this mean that motm system
will no longer be offering a ring modulator??

>e) VC Pulse Divider

Like a Serge divide by n comparator??  Cool!!

>f) Delayed Vibrato

Is this like the "LFO delay" on many synths??  Couldn't this effect be
produced by running the mod source through a VCA controlled by an EG with a
slow attack??

>g) Triple Pre-Amp

I've thought about this the last couple of days, and no matter how much I
think about it, it still sounds like a bad idea.  First off, most people
with microphones and real instruments already have some sort of pre-amp.
Secondly, if it's a triple pre-amp, then in the very least it has 3 ins and
3 outs, and that makes it a 2U module.  I also wonder why someone would
want to add pre-amps to their system in groups of three -- I could
understand stereo, but three??

I would much rather see a single pre-amp in 1U that kicks ass.  A 2U module
has a limit of 8 knobs, a 1U can fit 4 knobs.  These are features that,
imho, would go into a world-class pre-amp module:

1)  Variable input impedance -- while a rare feature in mic pre's,
differences in input impedance accounts for a difference in sound between
various mic pre's, and variable impedance is a very useful feature of many
direct boxes.  Then again, I doubt people would use 1/4" jacks with
microphones, unless they played harmonica.  Nor do I think getting 48V
phantom out of a +/-15V would be all that easy even if it had XLR
connectors.  At least this way you could use it with low-Z dynamic mics
like a 58 or 57 if it had a...
3) balanced TRS input
4)  Switchable high-pass filter -- corrects a multitude of ills and can be
used creatively as well, quite useful for both microphones (eg. SSL) and
real instruments (eg. Manley).  A HPF at the inputs is a large part of a
guitar amplifier's sound (eg. Marshall).
5)  A ground lift switch.
6)  A phase-reverse switch
7)  An overload indicator (it doesn't have to be a LED, what kind of light
bulb is in my Mini-Moog??  Do all lights make noise??)
8)  Gain control

I'm thinking that and only two jacks (in and out) could fit on 1U, although
I'm not sure where the FORTRAN compiler would go ;)

>h) Envelope Follower

Is this going to be a 1U or 2U module??  Unless it has some amazing
features I can't yet imagine, I'm guessing it should fit in 1U -- four
jacks: in, gate out, envelope out, reverse envelope out; and four knobs:
input level, slew, gate on threshold, and gate off threshold.  Adjustable
slew is very important.  One of the things that makes the Mutron popular
with bassists is that its optical coupling makes it rather slow.  Some
pedals which rely upon an envelope follower are so bad they clang on low
notes.  You'll notice that Bootsy Collins and Stockhausen never worked with
each other -- there's a reason for this :)

>i) SEM Filter

Woo hoo!!!

Delayed Vibrato - 1U special purpose module with built in sinusoid 
LFO, which is damped for natural delayed amplitude buildup. Yes, you 
could reproduce it rather closely with 3 other modules. It will be a 
boon to small system owners.

Triple Preamp - 1U, 2 line level inputs (for a stereo synth, for 
instance), 1 guitar level input. No mic inputs. I don't agree that 
this module is not needed. I don't have mics and mic preamps laying 
around. Most preamps are not optimized to amplify to the 10V p-p 
levels MOTM uses. If you do have something that does the job already, 
then you don't need this module.

Envelope Follower - 2U, I don't remember the announced features. 
Search the archives for details.

SEM filter - Paul promises it will have all the dc offset leakage and 
otherwise crappy specs of the original. Rumored to have a cool extra, 
maybe voltage controlled mode (HP, BP, LP, Notch).

Capacitance is an issue with *accurate* control voltages. That is why the
'820 has a special
driver circuit. For LFOs, etc, it's not that big a deal.

And, of course, some if it is just *showing off*. :)

Moe is working on graphics/mock-up. The 3330-based Ring Mod will be replaced
by *something*.
Just not sure what. Get the '110 while supplies last! (about 27 left).

Not, that just a slow attack. We want *voltage-controlled* delay :)

<snip>

I'm not going after Summit or Benchmark. The Preamp has 1 guitar/bass input
and 2 line-level inputs.
The guitar/bass has a gain of 150. The other have gain of 10. It is 1U wide
with 3 knobs and 6 jacks.

Probably 2U. Yep, it's going to be a mind-bogglin' thang. Uses dBx
technology.

Yep.

Triple pre will be worth its weight in gold for running my ext synths into

The TCV input to he UEG??  Of course, I can see how replacing 6U of modules
with one specialized module would be cost effective, space saving, and
convenient.

Well, why not??  Everything else motm seems to demonstrate a stellar
dedication to quality.  Even the two mult panels are quite clever.  If you
are going to include a pre-amp, I say include a pre-amp with an innovative
combination of features that will attract people to the system.  Then
again, this is merely my opinion.  I apologize if anyone found my comments
offensive in any way.

150dB??

OK :)  I thought there was an unwritten rule about having more than two
rows of jacks (which would explain the size of the 320 and 820).

I never said it wasn't needed.

>I don't have mics and mic preamps laying around.

However, I would think most people with electric instruments or microphones
have amps and mic pre's to go with them.   Regardless, if you are going to
plug a guitar or bass directly into your modular wouldn't you want it to
sound as good as possible??

Going into motm how many volts p-p is line level??  Is +4dB hot enough??
What about -10dB??  This is an important question.  Someone just posted
they need this pre-amp to use their 410 with an external signal.

>Envelope Follower - 2U, I don't remember the announced features.
>Search the archives for details.

I did, and all I found was a discussion about using the 820 as an envelope
follower, and the desirability to have threshhold settings for both gate on
and gate off.

While I still haven't received a technical answer to my question, I 
went back to the motm pdf catalog and found, "The MOTM-410 can be
used with any line level audio source (synth outputs, mixer effect 
sends, etc.)"  So I'm wondering why this pre-amp would be "worth its 
weight in gold" for such an application.

Please notice I'm not knocking the idea of a pre-amp in and of
itself. While I'm not expecting to be able to plug a bass or a green 
bullet directly into the 410 or 110, I am planning on using these 
modules with samples and other synths.  However, there seems to be a 
strong difference of opinion as to whether or not this will work.

 It's because the 410 requires a resistor to be taken out of the circuit for 
line level inputs. So if you want to use both 10v MOTM levels and line level, 
it's a little difficult...

Then the catalog seems awfully misleading :/

You can't build one 410 and use it for both internal and external
signals?!?  That almost defeats the purpose of my building this system.

So, before I end up buying a bunch of modules I can't use, exactly how hot
(in audio terms) does a signal have to be??

Something here doesn't make sense.  If the motm levels are so hot then how
does anyone ever use their system??   If the mixer outputs are too low for
the motm inputs, then the motm outputs would be too hot for the mixer
inputs.

I believe that line level is 1V p-p -- the old PAiA standard, which was 
adopted by no one else.

It's not as bad as you might be thinking right now. Don't panic, and
definitely don't let this issue scare you off from MOTM. I have no problem
interfacing my MOTM with the rest of my studio using only currently
existing modules. For mics and electric instruments, I'll run them through
a mic preamp (I use an ART Tube MP), and have had no problems getting a
strong enough signal for the MOTM. For line level signals, I use an Aux bus
from my Mackie mixer. Again, no problems. For output, I run the final 110
VCA output into a channel on my Mackie. You have to watch the CV gain on
the 110, you can overload the preamp on the Mackie easily, but once it's in
range, it's not a problem. I have Doepfer and Blacet modules as well, and,
other than needing 1/8->1/4 adaptors, have no problem plugging them
directly into MOTM, and vice versa.

I built my 410 to use the internal MOTM signals, and use a preamp to run
other signals into it. Have had no problem running bass, guitar, electric
piano, etc. In fact, what it does for a Rhodes piano is simply magical.

I apologize for overreacting.

That's why I asked the list.  I figure people here would know because they
are already using motm modules in the studio.

That's good to hear -- I have no reason to believe an ART Tube MP would be
so much hotter than any other pre-amp.

According to Mackie, their aux sends are +22dBu.

The maximum input level is +22dBu as well, according to Mackie.

I too have found using aux sends gets one real close to where they might
want to be at the input of a MOTM module.  Ihave also used headphone outs on
a mixer for the same purpose.

I have found MOTM levels to be right of the edge of being too hot into a
mixer like this.  Of couse, for a MOTM output going to a mixer, if would be
simple enough to just divide the voltage coming out of the MOTM with a
couple of resistors priot to going into the mixer.

I'll second this.  I've run both MOTM-level AND line-level (mixer 
sends, tape deck outs, other synths) signals through all three MOTM-
400 series filters without any trouble.  The only issue *might* be if 
you want to run, say a MOTM-300 VCO AND an external line-level signal 
through one of the filters simultaneously (using the ever-so-
convenient built-in-mixer that the -420 & -440 have); in that case, 
the only "problem" is that you'll need to set the MOTM-300 input at 
about "2" and the line-level input at about "8" to get a balanced 
mix.  And that's what the knobs are there for ...

Average and RMS usually mean the same thing, as RMS is a kind of average.
I think you meant to say peak and RMS.  Regardless, you don't want the peak
to be too peak otherwise low frequencies will peek through.

However, an extremely fast response might be very useful in many
situations.  So I think adjustable slew is an important feature when using
it with a "real" instruments for generating CV, and adjustable gate
thresholds are important for triggering other events.  Imho, I think that
should be its primary purpose.

In order to add enough features for it to compete with the side-chain of
existing studio compressors, it would end up being _very_ large and _very_
expensive module.  Also, minimizing the connection between the detector and
the VCA and having the properties of that connection remain constant is
important in getting the very best performance out a compressor using such
technology, which is the exact opposite of the situation in a modular.
Furthermore, the VCA and detector circuitry in such equipment is carefully
matched and trimmed, and often "non-linear capacitors" are used to
compromise between fast response and low frequency distortion.  They are
also placed in a shielded box with balanced connectors.  All things
considered, it would probably be much more cost effective to buy a device
optimized for that application.  Otoh, the side-chain inserts of studio
gates and compressors are audio, so you can't use them as a CV source for
your modular.  Of course, you could still patch up a motm compressor just
for fun :)


Next time you set up a PA, annoy everyone by using an Aphex Dominator as a
ring mod ;)

Actually, they are not the same thing and people often misuse
the terms.  I guess you are directing your comments at Paul
since it is he who wrote that though.

I have included the mathematical difference which I can elaborate
on from a mathematical perspective if needed.  There are several
people here who I am sure can elaborate from electrical and audio
perspectives.

This sounds stronger than I meant it to.  Sorry!!!  Too lazy
to rewrite.

You should know better than to have me do math :)  Anyway, RMS still is a
type of average -- that's what the "mean" in "root mean square" means.  I
wasn't trying to correct you, I was trying to understand the features you
were describing.

Anyway, you'll notice both equations are integrals taken over a certain
length of time.  I guess for a sine wave, that time can be one cycle giving
a "true" RMS value.  For audio, the longer the time the more average the
average, so my point was that time should be variable.  Afaik, even a peak
value is an average taken over a shorter period of time, otherwise it would
just be the rectified signal which would multiply the original signal in
the gain cell.

It's OK :)  I was just trying to clarify what you meant.

Is there such a thing as a chassis mount MTA1564, or does anyone have a

Good for you!!  I have a pre-existing +/-15V supply and several metal
project boxes it would fit into.  I imagine the 900-PCB is a PCB with a
bunch of headers on it.  So I'm thinking (I know, bad idea!! :) that I can
mount the 900-PCB on the wood behind one of the modules with some space
behind it (UEG, 320, 820) and then build a cable with a MAT-1564

like boxes with cables hanging from them, although I might just run the
mains through a grommet rather than try to cut a hole for an IEC receptacle.

I've been looking through the Digikey catalog for various options.
Switchcraft makes XLR's with more than 3 conductors, but they get a bit
pricey.  Considering that I don't need metal because there is no shield,
I'm wondering if there is something like a plastic Molex or Cinch-Jones
(like on a Mini-Moog) connector that is both chassis mountable and round.
Cutting small square holes or anything but a circle is difficult with the

Mark, I have three of the PCBs in my metal rack.   The existing ones have 12
MTAs and also some push-on faston lug connections that are designed to be
the source.  You don't want to feed the PCB distribution board with # 18
wire.  You want to use something larger if possible between the PCB and
power supply.  I use # 14 stranded in all mine.

Personally, I don't see that mounting the PCB wood is a big deal.  At 15
volts, wood is a pretty good insulator.  At 15,000 it woudl be a bad idea.
However, when I mounted mine in my metal rack, I just went to Radio shack
and bough some of those shallow $3 project boxes with the screw-on lids,
just big enough to hold the PCBs.  I tossed the lod and mounted the PCBs in
these plastic boxes.  Worked out real nice.

Amphenol makes some real nice round connectors too.  However, they are

Really??  That seems a bit much.  Are you running them over a long
distance??  My entire studio is run off of two 12/3 cords going from the
wall outlets to the power conditioners.  Most gear uses 18/3, including
tube amps that draw so much current you can use them to heat up sandwiches.
Sure most people use a microwave, but you can taste the difference with
tubes ;)

I notice that motm uses four conductors, but do all three go to the power
supply??  Since that seems like two grounds, I assume the first one is
common to the supply voltage, but what is the second one -- local, earth,
or what??  I'm thinking of buying this cable at Home Depot (who do not sell
10/32 or 8/32 inserts, btw, in case anyone is wondering) since 14AWG is
more like electrical supply than electronics supply.  I'll have more
choices in three conductor cable than four conductor cable.

Nor do I think the black paint I'm putting on the wood is all that
conductive either.  I have to see how I'm going to fit this PCB -- whether
I need stand-offs or have to mount it perpendicular to the board (like the
motm PCB's are perpendicular to the panel).

Also you could use a box like that and make it cable mounted!!  I have a
bag of clamp connectors to make clunkers, which will fit a plastic outlet
box.  Now the big question is whether the PCB will fit, how long is it??

That's a very good point.  Also, if I used anything bigger than 18AWG then
I couldn't use a MAT-156 anyway (at least not according to the Digikey
catalog).

I finally found a circular plastics connector called the AMP "Series 1".
It takes 18-14AWG wire and isn't that expensive, but the four conductor
connector is .942" inches in diameter, which sounds huge!!  So all things
considered, I think your plastic box idea might be the best of all.  That
way if I need to move the system, I could disconnect the box from the rack,
cable and all.

Well, the best connection for each module is directly to the power supply in
a star type fashion.  However, when you get your system up to the 40 +
module range, this is not practical.  So, I put the PCBs closer to the
modules they serve and run the larger wire to the PCBs.  So the current of
all 12 modules served from that PCB is on the wiring to the power supply.
OK, so whats the big deal?  It might be 400 mA or so per PCB.  The wire is
not sized to the current flow expected.  If it were, # 18 would be oversized
for everythying.  It is sized to eliminate small voltage drops between the
power supply and the distribution  PCB.  These unwanted voltage drops cause
by current draw variations in one module can cause interation with another
module.

You are comparing apples to oranges. The voltage drop in these AC lines
really has no negative effect on your gear.  Small voltage fluctuations on
your 15 VDC line do.  The AC supply voltage at your main panel routinely
varies by as much as 3 or 4 volts (more in California) even before
variations caused by voltage drop is considered.  We (power companies, my
vocation) vary the AC voltage delivered to your house on purpose.  US code
specifies anything between 114 and 126 as acceptable for residential
service.

Paul told me that he has one return for the negative power supply rail and

Hi All !

There are locking DIN connectors that have a different pin out than 
the MIDI ones .  Should be a bit cheaper than the xlr's .

They are much cheaper, but DIN can't be connected to an 18AWG wire, and
certainly not 14AWG.

Good point, but have you seen the size of rest of the system?? :)

This is true, and that's before it's regulated twice.

Most of the ones I've seen have been solid, not stranded.

Thanx!!  A measurement is exactly what I needed.  Although I don't think a
photo is necessary.  Now I have to go measure an outlet box.

Excellent!!!  I think I can find 14AWG/3 stranded without having to chop
down an extension cord (which isn't even an option with four conductors).

You have been very helpful.

THANX!!

I have just bought a pair of four pole Speak-on connectors for my power
connection to my new second box. I'll let you know how I get on. They
weren't exactly cheap though, about 12UKP for the all the bits for a
terminated cable.

LOL! Very funny stuff, I liked the Vince Clarke one. Did'ya hear about 
Spinal Tap? They're complaining the knobs only go up to 10, and some of 
them go backwards. Bolicks!
