I have done the following sketch for a raspberry pi based synth engine:
My idea was to use the OLED and navigation buttons to control how the the pi-zero maps different sounds to different channels. Probably using a selection of these engines: http://www.linuxsynths.com/index.html
It might be a good idea to add some encoders / potentiometers for sound control (aware that pi zero doesnt have A/D). Considered a pwm audio out, but think it is better to use USB soundcard (less complexity, better quality).
I think the Zyntian project is awesome, but rather complex and expensive. Here is a list of the engines they are using (most of them open source). https://zynthian.org/engines#synthesizer
I can design the module above, but appreciate all help on the Linux side!
Let me know if you can help development!

Have a look at Sunvox. Wicked flexible and well supported. Would probably require a larger/full-color screen but a Pi-based module with Sunvox DAW would be a great capstone for the Leet Synth modules.

I love sunvox since it is free and powerful. The only thing that I can complain about is that I have to redo midi config every time I reprogram a device (which has been quite a few times during development ;)
A 7″ touchscreen in an angled stand would probably look just as cool as the LED sequencer that I built…
This project is probably useful if you want to run sunvox with a custom OLED and interface (a Python wrapper for the SunVox DLL):
(super eager to check it out, but need to finish documenting current project first…)
And here is another way to make rasPiZ headless with sunvox:

Nice idea! I have some Raspberry Pi Zero W lying around doing nothing.

I have made a first version of a raspberry pi based sound engine. The OLED and keys are working and I found a python-based menu system that allows navigation, configuration and execution of various commands.
I think it would work great with software synthesizers as:
The UI can either use 4 or 6 keys for navigation and there are 4 or 6 keys left for selection of presents.
If anyone wants to help with development and integration, let me know.
