Re: [Csnd-dev] [EXTERNAL] [Csnd-dev] Daisy build info

I guess I can hopefully just use the arm-cortex-m7 build in the beta
release. I still have to work out how I'm going to work with Daisy. I have
three Noise Engineering Eurorack modules that are based on Daisy Seed, so I
should try working with one of those first (probably Alia). I plan to start
by adapting the Risset Harmonic Oscillator and the Binaural Reanimator
designs that I made for the Qu-Bit Nebulae. It will probably be a while
until I have anything to show/share....
