Analogue systems

You're a Cal Arts Grad? Yo - I'm having dinner with Barry Schrader tomorrow
night !

If I was stuck on a desert island and could only have one - I'd take the
Blacet.
But it's real real close.  The AS is a fine oscillator.  I prefer the
separate FM inputs and the log/exp selection for that input on the Blacet
model.  Also, the Blacet has the all-important fine tune pot on board and
yeah, the triangle to square waveshaping is great.  It sounds like the Serge
Waveshaper to a certain degree.

Both are very stable.  The sine outs are a little more pure on the AH, but
both have a touch of the third harmonic caused by smoothing a triangle wave.
The AH sine waveshaping is interesting.  goes form sine to something very
close to a ramp form the sine output and their ramp out goes between that
and triangle.  So even though the Blacet has the triangle to square
waveshaping via VC or pot, I think AH has him beat here

All of John's VC input's do a lot - full range, and quite useful.  However,
I like the way AH comes with a scaled VC input as well, not just two 1v/oct
inputs without scaling.  I have since added full +/- processing to one of
the two VC inputs to all my Blacets and I like that a lot better.

John's osc's have a huge range - they go slower than both my Analog Systems,
CEM, MOTM and Doepfer LFO's and up to about 14,000 cycles!

But alas, I had the fortune of playing around with a Buchla VCO last weekend
- first time since Cal Arts and neither the Blacet or AH do what these do
timbrally.  That wonderful FM input - God, nobody has that down like Buchla
did.  Don's osc don't track - never will, they are as stable as any other
osc designed in the 70's, which is nothing like what they are capable of
doing now, but that sound!  Ultra pure sines, great waveshaping.

Hope this helps!

Hi.  This is my first post to this group, since I am just putting
together my system.  Can anybody tell me what they think about the
RS95 oscilators v. others, such as the the Blacet oscilators?  I
would like to hear (read) Peter Grenaders opinion, since I noticed he
has 4 Blacets and one RS 95 in his system, and like you Peter, the
good ol' Buchla in B303 is the system I remember most fondly ('83
grad) I particularly liked the Buchla's VC timbre modulation, going
from sine to sawtooth or square. The RS 95 looks like it could do
something similar with the VC sawtooth wave, going from triangle to
sawtooth.  Anybody used this feature?  How does it sound?  Can you
post an mp3?  Any disadvantages over other oscilators? (Right now I
only have Doepfer A110 oscilators, which are not very useful for my
purposes)  Anybody who can give me any opinions, please let me know.
Thanks.

The MOTM-320 VC LFO goes through one cycle in 30
minutes when set with just the panel pot.  When a CV
of -5V is applied, the cycle time is about once every
2 1/2 hours.  I don't think the Blacet VCO is slower
than that is it?  Peter's statement may be true for
the other systems though.

Additionally, the MOTM-300 VCO's top rate is in excess
of 38 kHz.  Its slowest rate (although not as slow as
the Blacet VCO--but this is necessary since Blacet
does not currently have a dedicated LFO in its
line-up) is one cycle every 5 seconds.  

Cheers!
Todd

Shit  - once every 2 1/2 hours?  this is slow and I stand corrected.  
My only experience with MOTM LFOs is the one in his truple 
resonant filter, the only MOTM i own.

Nice -And I think the MOTM has both a soft and hard sync, yes?   
That's a another great feature.  but I prefer the functionality of the 
Blacet sounder.  Ait's the expo FM in is great for those 
oh-so-close-to-subotnick sounds. I also forgot to mention John 
has a dedicated jack which will raise (or lower) the pitch exactly 
one octave if a + voltage is applied, and down one if a negative is 
applied.  I don't use it much as I am not  into synthesis as a 
keyboardist, but for those who are this is very useful.

nighty night,

Peter

Does any one use doepfer mcv24 ? I want to know if it works well with AS.
Is it possible to make my synth polyphonic with it ? Something I'd like to
do is to split my keyboard in two parts (left hand and right hand) so that
each part plays a different voice. Is it possible to do that with the
mcv24 ?

Arnauld

hi arnauld,
yes, you can make your intergator polyphonic(up to 12
voices,i think,if you have 12 vco's...).i have already
made some monster 4-note poly pads with my mcv24 and 8
a111's of my doepfer modular.as for keyboard
splitting,this is possible,too....you use just two
mcv24 cv/gate channels and set them in the same midi
recieve channel with a different note range each of
them.
