Hi everyone, I'm trying to use de Linux Valon Synthesizer made by Patrick Brandt (link below), but i have problems with the port. I have the following error: SerialException: Could not configure port: (5, 'Input/output error') If i have a Roach plugged to ttyUSB0, what parameter should i use when i declare an object of type Synthesizer? I have Ubuntu 14.04, and i run the code with ipython.
