ComputerVoltageSources

I was reading about the Quad Thomas Henry Bass ++ drum voice module at
http://www.birthofasynth.com/Thomas_Henry/Pages/Bass_Plus.html

It made me think about using the CVS as a drum machine interface.  I have an Alesis HR-16 Digital Drum which has 16 programmed samples. I wrote the program  "CVS HR-16 Interface (rev0.0s).DJB.bas" that maps four independent CV inputs into the 16 drum sounds and sends the appropriate note messages to the HR-16. I used the additional four inputs as enables for each of these channels. 

I used my 4 Channel ComputerVoltageSource with the "Divider & Pseudo-Sequencer (rev0.3X).DJB.bas" program to create the four channel enables from a set of dividers (in this case /4, /5, /6, /7) and clock both modules from the same source. It would be easy to just incorporate the counter portion of this code directly into the HR-16 program so it would only require a single module.

I'm running four sine LFOs to generate the CVs for the four simultaneous drum sounds. These, combined with the enables generated from the Pseudo-Sequencer program, create a really nice set of non-repeating drum patterns for my modular.  I can use my sequencer clock as the master so everything is synchronized.

I know there were 30+ PCBs purchased.  What are people doing with them?  Are they just sitting in drawers?  I only know of two that have been completed.

If you bought it and didn't build it, why not?  What are you missing?

I'm always amazed at when another modules inspire a pretty simple program to provide a pretty similar need.  In this case I can't synthesize the drum sounds, but the HR-16 does that very well.  It's nice to have a non-repeating but interesting set of drum patterns.
