Right on!

I've been looking at the Axoloti. It is mostly there as-is. Kinda takes 
the wind out of the sails.

I'm into doing a platform. Perhaps use Axoloti as a starting place and 
morph it to our needs. I like the Wifi thing. It enables iPad and OSC 
control ..  heh heh.

Also there is the polyphony possibility.  I know there is probably 
enough power in one proc to do multiple voices, but as the patch grows 
the bandwidth shrinks. It would be a small thing to have multiple procs, 
one for each voice.

The thing about keyboards is this: For one, raw keyboards are hard to 
find, and two, there are so many midi controllers out there for cheap. 
I'd be inclined to let the user pick his keyboard and just plug it in.

However, I've seen many similar projects get stranded half-way because it really really takes a lot of coordination, good UI design, debugging, testing, etc to get something that is as pleasant to work with as the Nord G2. Additionally, doing that in VST rather than hardware also solves many initial problems (though sacrificing playability IMHO).

> The most important thing about your idea to me is: let's combine forces and make a monster of a synth! Something no one could ever pull off alone. Something that can grow for about 5 or 10 years (I'm thinking like the MidiBox platform did for quite a while). Personally, I'm more into the hybrid stuff, combining a modular DSP environment with analog voice-cards and effect chain options.

Oh, and when we do something big and long term, it also pays of to put a decent keyboard in it with aftertouch, rather than the cheap mini-keys we get from the big corp's these days.

Then I found the Nord Modular and that seemed to fill the need nicely. Why re-invent the wheel?  But then they get discontinued, and used G2s go for $1000.

>> I did some research. Someone out there has a clone for the app that configures the synth. If that code is workable then we just need the synth side.  On that front there are several excellent choices for a processor. I'm thinking a high-end STM32. We could start with a Nucleo board with a daughter board; nice and cheap. The code will be intense, but many hands makes work light.
