Hi, The following patches group together most of raw serial comms with external synth and makes rest of the code agnostic to it, so that raw serial comms can be easily replaced by an alternate way to communicate with external synths. Plan is to follow these patches with alternate implementation of comms with external synths and then migrate existing synths to use the new implementation.
