In addition... the Shruthi-1 uses an ATMEL, it's an AVR, not a PIC.
My thoughts: yes, the Osc system is too limited. I can recognize the oscs most of the time. The filter is amazing, so improving the oscs is the way to go.
This is, after all a paraphonic synth, so for realistic, cheap mods, it will stay this way, or else if you want a real polyphonic one, you can get a DW-6000 or DW-8000 (got a broken one for $75 that I resurrected), or a DSS-1.
Check out what this guy did - he stuck a Toshiba Libretto with some FM virtual synths connected to the MIDI-OUT and also the circuit board of an Alesis NanoVerb inside.
Sounds fantastic.
Something along this line would be awesome:
1. Use an Arduino-based, flexible OSC system, i.e. 3 to 4 Oscs with mixing, cross-mod, sync, Minimal FM, divide-down if necessary (to mimic the classic paraphonic string synths), and inject within the Filter
2. Stick in some additional multi-effects if possible
The best thing ever would be to have a full computer with tons of good VST through the filter.

This helps us to keep redundant information from showing up everywhere and also allows us to constantly improve the format and structure of the documentation. We talk about the HAWK-800 quite a bit but we also discuss and help owners of the original Poly-800 models. So don't be shy if you haven't got the HAWK-800.Yahoo! Groups Links
