[sdiy] Someone Mentioned dsPIC

[Richie Burnett]

It's good to see someone else using the dsPIC.  12 voices is good going. 
What clock rate and sample rate were you using?

I use Microchip products a lot with my day job, but enjoy using them for 
electronic music projects too.  The 16-bit word length can be a bit limiting 
sometimes for audio, but you can still get excellent results with careful 
programming.  The combination of microcontroller, peripherals and DSP is a 
powerful one, particularly in the dsPIC33F case where there is built-in 
multi-channel DMA too.

What's your future plans for this project Scott?

-Richie,

In an earlier recent thread, someone mentioned dsPIC.

I've been working on dsPIC stuff.  The most recent development is a single
dsPIC system that supports a 12 voice Karplus-Strong MIDI synthesizer.  The
dsPIC runs the 12 voice engine as well as a MIDI controller which gets
about 8 MIPS of processor power worst case.

Here is a link to a demo:

No effects were used.

Please pardon the noise...

The synth is built on stripboard.  There are 4 ICs including 1 dsPIC.
