Dear members,

thank you for the participation on the polls (though I'd like there would be
more attendees).

Most of the results correspond to the way I see it.

The development of a window comparator could be realized within a few hours
but I'm not assured that really 62% of the users would need it. Anyway - I
could make it as kind of relaxation exercises between the bookkeeping :-)

I will have an eye on the suggested wavetable module (we have a similar
prototype in the drawer since many years) and the apeggiator module. The
USB-to-CV/gate interface is on our list in any case and is already under
development as we currently gain some USB experience with the USB versions
of our master keyboards.

For the XYZ trackpad controller I will see if we can find a suitable
3-dimensional sensor (as used in the Kaos pads or the Voyager). If anybody
knows the manufacturer of these pads please let me know. If we can find a
suitable pad the rest would be  easy.

Best wishes
Dieter Doepfer

Perhaps you know these already, Dieter, but it's the only ones I know  
of:

http://www.interlinkelectronics.com/force_sensors/products/forcesensingresistors/standardsensors.html

http://infusionsystems.com/catalog/index.php/cPath/24


And then there's of course TacTEx, which was used by Big Briar in a  
touchpad (many years ago), and perhaps also in the Voyager:

Thank you. I know Interlink (their pressure sensors are used e.g. in
R2M/A-198) and also Infusion Systems. But as far as I know they do not offer
three-dimensional XYZ sensors and the Infusion Systems products are very
expensive. One would have to stack two two-dimensional square shaped sensors
(X+Y) and a pressure sensor (Z). This leads to a poor sensitivity from our
experiences. Especially the second (lower) position sensor becomes much less
sensitive than the upper one. I'd prefere an all-in-one sensor.

I did not know Tactex. Their website looks promising.

Yes,  when researching XYZ controllers recently, I stumbled upon  
Infusion, and I was also wondering (or rather: scratching my head)  
about their "solution" to have pressure sensitivity...

Here's a link to the Moog Touchplate on Matrix:

http://matrixsynth.blogspot.com/2007/11/moog-touch-plates.html

Upon further investigating, the grapevine says that Moog abandoned the  
Tactex pad on the prototype Voyager for another (more analog) product,  
probably the same one as used in the Big Briar ones.

I've been looking at XYZ controllers for a while now, and sadly it  
seems rather difficult to find the correct solution (for a reasonable  
price). Hopefully you can come up with something, Dieter, as this is  
something I'm sure many modular enthusiasts (also outside of the  
Doepfer community) would love to ehm, lay their hands on...

We have a working XYZ prototype but it's much too small after my fancy (only
65x50 mm). A bit like the touch pad of a laptop. I think that most users
want to have a much larger working area.

Mostly yes, I guess. A bit more Voyager-size like.

Then again, small ones would almost perfectly fit the bill for the  
"keyboard-like" pads I had in mind. So, how many prototypes you have  
left, Dieter ? :-)

We have three of the pads but only one prototype electronics (no housing or
front panel, only a pcb) that converts the digital data coming from the pad
into CVs. And we want to keep it for reference, sorry :-(

A module with 3 or 4 of these smaller XYZ controlers with seperate outputs including a gate for each would be pretty nice.  Cost may be a different story.
