[sdiy] Analog Devices SigmaDSP

I use the ADAU1701, programming it with SigmaStudio.   You probably could build a synth with it by linking it with an MCU to do some of the slower control stuff, and to interface with MIDI or whatever.

There's also a similar, though not compatible TI part with moreorless the same spec.

As you say they are very cheap so get an eval and try it.  It's a bit frustrating getting Sigma Studio going at first - it's not the most intuitive of software packages - but by flicking around the pages you should get something going.  I think there are sine and other (possibly non-band-limited) waveform generators in there somewhere.

I’ve always been intrigued by Analog Devices SigmaStudio software as it looks so much like a software synth.  Any of you have experience with it and whether someone like me with very poor math and programming background could get some enjoyment trying an eval board with one? I suppose I’d be willing to try learning basics with a decent book… There are so many different chips that I’m overwhelmed. I see diy board offerings for boom boxes that are amazingly cheap - Google Wondom DSP. I also have a daisy board but don’t have the programming skills to get anywhere with it.  I haven’t given up - just distracted now by this as we may use one at work.
