welcome @sobrilliant and nice to hear that you managed to set up Senselosc, my attempt to use sensel morph e.g. with SC3.
I am not sure what sensel is planning but, honestly, reading their FAQ I am pessimistic about a dedicated package for M1 from them that includes the `SENSEL_PRESSURE" flag… maybe @peter_sensel would like to comment on this or put an explicit statement into the FAQ?
however, as noted in my message further up, I managed to compile and use the open source part of LibSensel on my M1 machine with the steps I described above. Where exactly do you fail in the XCode compilation process?
