[Coco] Full Midi Synthesizer on a CoCo

[Bill Pierce]

Chad, I worked with screamtracker and the later modplugtracker. I liked being able to use custom samples for things. Also good for doing "background" tracks for things. I still use the modplugtracker for certain things here in the studio.

As someone already mentioned, I believe the best answer probably lies with a 
microcontroller interface.  We already see a Atmega Microntroller feeding the 
CoCo SD card data as in the "CoCoSDC"  There have been other Coco Projects 
involving these controllers too.

Take this project that has video demonstration of a Arduino (i.e. Atmega 
Microcontroller) working a 4-voice WAVETABLE MIDI audio system.  If you started 
with something like this ...

It would just be a matter of figuring out how to have it get it's commands and 
data from the CoCo on a custom cartridge PCB.  Seems very doable to me.  As I'm 
a big music fan and used to be BIGG time in the old .MOD and .ST3 
(ScreamTracker) PC sound formats, which was kinda sorta a simulated wavetable in 
some regards, I would love to take a stab at this myself and work on one.  
However I've already got unfinished projects all over the place :/

Yes but there seems to be more complexity that what I initially thought.

There must be a way to improve CoCo sound capabilities in an economical way that 
can be utilized for Music and Games and take some of the burden of the cpu.

A microcontroller solution seems the closest bet.

 If the device only accepts serial, like the Speech/Sound Pak, then it would be 
nice to interface it like an RS232 pak, with memory access versus bitbanging. 
POKE POKE POKE.

 Otherwise, one could take one of these and but MAX232 on it to get it to RS232 
levels and just plug it up to an RS232 Pak…

 Nick, is that your desire? To stream MIDI to it? It would be less overhead than 
making music directly, I am sure.
