Have been experimenting with a Pi recorder using Audacity.
I have built a corner unit with a DSX-A50BT hooked up to a scooter battery for the frequent blackouts. It is capable of doing lots of stuff but I need to find time to set it up.
I also have a bay for my Eurorack MX-602A
The Pi itself I have verified works but the excersise of learning it and getting it to record still lies ahead.
There is the guts of a Stromberg Carlson wireless there too. The amp seems to work but I need to build a buffer for it to get the signal voltage right.
