Thanks for super quick response.
I'm just getting started with Zynthian and what I want to do musically, so I imagine as I put my Zynthian system together, I'll learn more about what I need/want and don't need/don't want ... so I'll take a best guess on hardware, and work it out from there.
I had been looking around at Korg/Roland modular synths, but, realistically, at the moment I can't justify the expense for a hobby.
Totally understand you guys having an officially supported platform, makes developing the code easier/faster for mainline release, and also puts Zynthian in the hands of people who don't have hands on skills via your kits - I wouldn't want to see it any other way
Wasn't aware of the Linux limitation with MIDI-over-ip, thanks for highlighting, I'll do more research for sure.
Headless - I'm not tied to xRDP, so if there's a way to do it, I can figure the rest out.
Probably I'll go for RPI hardware with a DAC board to start with, composite video display is looking very economical right now, MIDI "to be advised" will either duplicate your circuit on stripboard or one of the arduino circuits ones I've seen around for MIDI, and have USB MIDI cable on standby. Once I have it working, and understand the environment, I can experiment with PC motherboards or other ARM boards.
Perhaps I will be the first to Intel/AMD'ify it, who knows ... I'll try and report back with progress over the next few months.
Thanks for your time and help, it's appreciated. And thanks once again for putting the project together for us, great work.
