I'm learning another device at the moment, it's this weird hollow wooden thing with metal and nylon strings stretched across it. I can't figure out where it plugs into the mains, it only has a single audio out port, and no midi (argh!). Oh, and if you think analog synths have tuning drift ... !
I'm looking forward to routing its audio through the FX version of M42 (hint, hint)!!!
