hi. wouldn't a 3-ZONE cymbal pad make perfect sense? 1=crashing it, 2=
riding it, 3=THE BELL !?!

does this seem like common sense to anyone else?

:)

[i'm new, doing some recording with a dtxpressii and am considering buying 
one...and or a roland kit.]

Roland makes a three zone cymbal pad, but it takes up two trigger 
inputs.

If you can hold out, the Yamaha PCY150 that is about to be previewed 
an NAMM next week, will be avialable in a month or so. You can see 
it on the kit on our home page here. The nice thing about the PCY150 
is that it will work on the Dtxpress II on inputs 2,6 and 7 and 
there is already a trigger setting in the module specifically for 
the PCY150.

hi OGD,

are you saying that the forthcoming Yamaha PCY150 is going to be a 3-ZONE 
cymbal pad ???

also, do you know the model of the Roland 3-Zone cymbal pad?

:)

If you don't mind, I'll let OGD sleep and answer in his stead. The 
PCY150 will allow bell/bow/edge use but, technically, not as three 
distinct zones, but as one piezo zone and two FSR switches--if you 
use a suitable input on the DTXPress II or III. The Roland CY-15R, 
which the TD-10 (and maybe 8) can give either bell/bow capability or 
edge/bow capability, becomes a bell/bow/edge cymbal via a setting on 
the TDW expansion card for the TD-10.

I can't help you on the Roland model number but I can confirm that 
the Yamaha PCY-150 is indeed a three-zone pad ie bell, bow, edge.

I've been waiting for its release for some time now as it's a more 
efficient use of the module's inputs than using a separate one for a 
bell pad.  I just hope I can get one here in the UK without too much 
hassle.

Yes, it will have bell/bow/edge voices with choking. It should 
really be similar to the 3-zone TP65S trigger pad, with one piezo 
for the bow and two FSR ribbons, one for the bell and one for the 
edge.


OGD

Does anyone know Yamaha's wiring convention to get  
three-zones from one pad, using a single three-conductor 
cable?  

(For two-zone cymbal pads, piezo signal travels via tip, 
rim-switch # 1 is on ring: what of that 2nd rim-swtich?)

I've been wondering that since hearing of the new single input 
PCY150.

TIA,
Chris

Well. I have always wondered about this since the DTXpressII TP65S 
pad, with its two rim switches and one piezo.

I suspect it's fancy electronics making a single "switch" on 
ring/sleeve distinguishable by the module - perhaps level-based or 
something - rather than say tip/ring for the second switch.

The reason I say this is that I have a Pintech SE-102 pad as a snare 
on my DTXpressII module, but I leave it set up as a TP-65S pad type. 
The SE-102 is a stereo pad with a single rim switch, so I should 
just get the rim1 sound every time I strike the rim. However, every 
now and again, I get the rim2 sound when I strike the rim. I haven't 
pinned down the circumstances in which it happens, but the fact that 
it does suggests it can somehow distinguish rim1 and rim2 on the 
ring/sleeve combination.

OGD, anything obvious from the circuitry when you disassembled yours?

Stewart

you guys are great, thanks.

do you know if the PCY150 will be included with the DTXpress III kit ?

or if it will be an add-on?

do you have any idea what the cost of the individual PCY150 pad will be?

is there any info online about it?

:)

Stewart/Chris,

The tip/sleeve are run separately through two resistors R1 & R2 to 
the connector CN1 that has the two leads that goes to the piezo on 
the metal plate on the pad.

The ring/sleeve are run separately from the piezo circuitry. The 
ring circuit is split into to pathways, one circuit is run directly 
to the rim 1 FSR and the second circuit is run through a resistor to 
the rim 2 FSR.

Thus a large current passed through the ring/sleeve circuit is 
interpeted as rim 1 triggering and a small current passed through 
the ring/sleeve is interpeted as rim 2 triggering. 

There is no connection between the circuitry of the piezo and the 
rim switches.

The TP-65 has the same PCB as the TP-65S, except the single 
resistor  R3 and Connnector CN2 are not present.

OGD

Hi OGD,

Hmmm, interesting.  Thanks for the info.

It should be very straightforward to solder together a 'y' cable 
(with series resistor in the ring 2 pathway) to use a Roland 
CY-12R/C or CY-15R (3)-zone pad in one of  the newer Yamaha 
modules.

Maybe not important to you guys (who would just buy the 
PCY150), but nice for those of us who have Roland guys who 
may want to convert pads to be compatible with the DTXtreme IIS 
module (depending on what else happens at NAMM)....

Chris,
 
I little followup. I did a little more surgery, i.e. disconnecting 
leads, splicing.

When you disconnect the piezo in the pad 1, the rim switches in pad 
1 will not trigger on their own. I then patched a piezo from a 
second mono pad 2 on the other side of the kit directly to the 
ring/sleeve  of a plug that goes directly into the module. I then 
patched the rim switches from pad 1 onto the tip/sleeve of the plug 
that goes directly into the module. If you strike the the piezo on 
pad2 at the same time as you strike the pad1 rim switches the rim 
switches will trigger the correct voice assigned to the rim.

So in other words, even though there isn't a direct connection in 
the pad it self between the piezo/rim FSR, the module does need a 
near simultaneous strike from both the piezo (no matter how little 
the strike is) and from the rim switch in order for the rim switch 
to trigger the Dtxpress module.

Once I get some of the newer pads that are coming out after NAMM, I 
will do some more destructive surgery on some of the older pads. 
(i.e. un-soldering, removing resistors, etc.)

OGD,

Interesting. Even from the perspective of a layman, I suspected as 
much. Do you know What the three elements in the Rolands are, and how 
they interact?

Ed

will the the PCY150 be included in the new DTXpressIII ???
[this "virtual" 3-ZONE cymbal pad]
or will it be sold separately?
does anyone know?

You know, you really ought to make use of the group archives. A 
great deal of information has been posted about the DTXpressIII 
since it was lauched in Japan in November.

The kit will come in two forms: STD (with the current PCY65 cymbal 
pads) and SP (with the new PCY130 and 150 pads as well as the new hi-
hat). The pads will also be sold separately.

Stewart

Hi OGD,

First,a disclaimer: 

Most of what I know of triggering comes from the Roland stuff.  

I had an DTXreme module for a while (a few days), and played 
with the DTXpress for an even shorter time (when a certain mail 
order company sent the DXTpress to me instead of the blem 
DTXteme module I actually ordered....  But THAT'S another 
story....)   :)

Therefore, please forgive me if I say something  that seems 
blatently obvious or that you all already know; I do it to try and 
avoid the potential for confusion that can arise due to differences 
in the way these modules detect trigger signals.

As we'd expect, as 'rim' triggering generally requires:

a)  trigger signal from a piezo AND 

b) rim-switch closure.

If these occur simultaneously, the module will know to trigger the 
sound assigned to the 'rim' (at least when a 'piezo/rim-switch' 
pad type is selected). 

In other words, you generally need a piezo signal on tip-sleeve, 
and a closure of the rim-switch detected by the module on 
ring-sleeve...  The piezo and rim-switch don't even physically 
need be on the same pad; the signal changes just have to occur 
simultaneously.

Basically, that's how the rim of a dual-piezo pad is wired: 
ring/sleeve (same  as the rim-switch).

Now, obviously we can trigger the 'rim' sound with a dual-piezo 
pad in a trigger input that can handle dual-piezo pads (like the 
snare input, when the proper pad type is selected).

You didn't say what 'pad type' was selected when you did this, 
but even there, it IS possible to trigger the 'rim' sound with a 
piezo element (say with a dual-piezo pad), even when the 
piezo/rim-switch (e.g. PCY80S) 'pad type' is selected.  However, 
the very big 'catch' is you generally can't fire the 'rim' sound 
reliably from that 2nd piezo....    Why not?

The generated signal occasionally appears to be a rim-switch 
closure, but the problem is results are unpredictable, and hard 
to control when playing.  That's why dual-piezo pads don't work 
reliably (if at all) when a 'piezo/rim-switch' pad type is selected....

Kind of a OT: when I had those Yammie modules I confirmed 
that "Shack Adapting" does work quite reliably with the Yamaha 
modules.  This little mono-to-stereo adapter allows you to trigger 
head and rim sounds from mono-piezo mesh pads in a velocity 
cross-switching fashion, and in a very predictable and 
controllable manner.

Maybe not a deal for you DTX guys, as you have 
layering/switching capabilities in your modules, but who knows...  

Here's a thread from VDrums.com that'll basically applies to the 
DTX family of modules, too:

http://vdrums.com/forum/showthread.php?s=&threadid=14272

At the very least, worth looking at, since the thread talks about 
some of this signal detection stuff....

I suspect the Shack Adapter MAY allow you to trigger all (3) 
sounds in a velocity cross-switch fashion with those newer 
trigger inputs, using only a mono-piezo mesh pad.  Maybe I'll try it 
at NAMM, if I get a chance.  ;)

Are you sure you didn't actually wire the rim-switches on pad 1 
as "ring-sleeve", and the piezo on the mono pad is wired 
"tip-sleeve"?  That would make more sense....

If you really did mean it the way you wrote it, then I suspect the 
rim switch is kind of a 'red herring' in this experiment: it's 
probably only the piezo triggering the rim 9as I mentioned 
above).

But even there, notice in the first paragraph I used the disclaimer 
"generally", when mentioning the simultaneity requirement for 
rim triggering.  Why?  

I have in fact held a disconnected rim-switch in my hand, wired it  
'ring/sleeve' to a plug, without an attached piezo, and triggered 
the rim sound just by closing this circuit.   No piezo involved.

What I think may be happening is under certain conditions the 
module may build up enough of a voltage difference across the 
rim-switch element on the ring-sleeve pathway enough to be 
confused when the circuit closes (almost like a capacitor 
charging up or something)....  Just a guess...  Maybe some 
charge is being detected from my fingers: dunno....I never looked 
deeply into it.

I think you're referring to the fact that the two signals need to be 
detected simultaneously, and the elements don't need to be on 
the same pad?

Chris,

Pad1 was a TP65S (stereo pad, one piezo/two rim switches) using only 
the rim switches.

Pad2 was a TP65 (mono pad, one piezo only).

Even when both were connected (Pad1 rim + Pad2 Piezo), striking the 
either rim produced nothing. Only by striking both pad1 and pad2 
produced the rim sound.


OGD

HI OGD,

I understood that you were using a mono-piezo/dual rim-switch, 
and mono-piezo pad, and isolating the rim switch pathway from 
one pad, and the mono-piezo pathway from the other.

What I was asking was what 'trigger type' setting you selected on 
the module's trigger selection menu.  You can end up with 
interesting results when mixing and matching pads with different 
designs with different 'pad type' settings on the module.

But in retrospect, I think I gotcha.  And as you've shown, the 
rim-switch and piezo don't have to physically be on the same 
pad, although reliable triggering of the 'rim' sound pretty much 
demands having a piezo on the same pad as the rim-switch.

A pretty easy approach to separating the triggering of the 'head' 
and the 'rim' to two physically different pads involves using a 
stereo 'y' cable (headphone splitter) plugged into the same 
trigger input.  

I do that frequently with a PCY80 and PCY80S, since hitting the 
edge of the mono-piezo pad gives the 'head' sound, and hitting 
the 'edge' of the piezo/rim-switch pad gives the 'rim' sound.  All 
you have to do is hit the pads on their edges (kinda like what you 
do with 'real' crash cymbals)....

Chris
