The dsp-Gshield

My dsp-G1 synth is really getting air under it’s wings at the moment.

This the dsp-Gshield that I’m designing.
Just about the coolest shield you can stick into an Arduino board at the moment.

It has the dsp-G1 chip with MIDI connected to the Arduino TX-pin and a 12-knob control surface right on the shield.
Even better, it has a 5v analog bus for the parameters + CV/Gate for the note input.

If your into modular, this one is your friend and don’t need MIDI.

But it needs one Arduino Uno to host it.

I don't know anything about Midi but am an avid arduino hobbyist. I would like to learn what a DSP chip has to offer but don't know where to start. Is this shield only useful for synthesizing music ? Do you have any links you can recommend for learning DSP chip applications ? Are you writing a library for your shield ?

Yes, this shield is just a MIDI synthesizer with analog knobs for modifying the sound parameters.
And yes, it has a library but only for reading the analog inputs and handling MIDI.

A dsp (digital signal processing) is really a general description of the algorithms processing an analog or digital signal.

A dsp-chip is just a really fast CPU with special instructions to do fast signal handling and floating point math.

It is generally programmed the same way as any other CPU/MCU.
