Guys/Gals(?), I am working on a synthesizer for an Indian instrument (Tanpura, an instrument with 4 strings,that are plucked in a regular sequence continuously, for most live performances). My algorithm is straight forward and involves STFT based analysis and synthesis. I already have the C program working on PC platforms ( You can ask me (umpmpm@gmail.com) for a demo, it sounds good !!) and I plan to take it to market. Do you have any suggestion for the processor that I can use. What I should be able to do is, have at least 500 MIPS, parallel port/GPIO pins to support a 3 digit LED display and input jog-wheel to change options, 44.1 KHZ sampling of all the four strings. Help is appreciated.... Thanks, HSM

Help is > appreciated....GPIO pins to support LED and jog-wheel are pretty mundane. 500MIPS is not so, but is reachable. Do you need floating point? Do you _really_ need 500MIPS? Have you started looking at data sheets? That's probably next. If you can't get the MIPS you need plus the GPIO ports, you may want to use some little 8-bit processor to do the user interface part, then a DSP that just does the music synthesis part. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com Do you need to implement control loops in software?

I'm pretty sure they have eval boards with 4 audio inputs. -Jeff
