Still over here advocating that the Zynthian project recentre itself on an MCU platform which can connect to any computer.
RPi is a liability at this point, vis-a-vis what we - musicians using FOSS synths and DSPs - need. It has been a great boon to those of us who want to get into this, but this project, given things like the Access Virus firmwares becoming available, has outgrown its constrained little world. IMO.
