ComputerVoltageSources

Hi Dave,

 

With great embarrassment, I'll admit I'm one with a board in the drawer. I
don't need anything, except to work down my list of modules to build.

Subject: [ComputerVoltageSources] Drum Machine interface

 

  

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.
