I recorded this one a while back, with the UNO Synth and UNO Drum. If there's ever been a pair of machines geared towards improvisation, it's that gruesome twosome.
If you're thinking about making music, use whatever you have. Sample your silverware if you have to. There are ways. In my case, it's a roomful of boxes meant for jamming, and a few plugins to make the jams sound great. You can do the same thing with a DAW like Ableton Live or Reaper, and some subtle (and not so subtle) mixing and mastering.
Do it. There is no better time than right now.
