Hi all,
this is stuff for the hardcore programmers: Circle.
It as a kind of SDK for developing applications running on a Raspi without any OS - called bare metal. I am just trying the sample-29 (a miniorgan) for testing the MIDI capabilities. Hope to get other stuff also running so perhaps I can port MicroDexed and MicroMDAEPiano to the Raspi 
Regards, Holger
Whoa! I just tested sample 29 (miniorgan) and: YES, IT PRODUCED SOUND!!!
If I can port MicroDexed back to the RPi(3) I have much more CPU power for more voices or different sounds with 16 voices at the same time (I hope).
How about a DX1 ? Should get two instances of Dexed at once… 
Since a “dexed” is an object, you could run even more of the engines in parallel.
The problem is not the software, but the time for coding…
OB-Xd would be an interesting one too as that currently struggles on some patches with the full 8 voices.
In theory: yes. In practice: You have to keep in mind that you have to additionally write every piece of code for setting/loading/storing parameters on your own. And you first have to extract the engine of your synth and adapt it for circle. I thinkt it will be possible the more time you invest on this project
