Bassline 101 synth this weekend. Although the original (free) Bassline synth did share the same sort of specs as the Roland SH-101, it didn't sound much like the real deal. All that has changed with the commercial version, Bassline 101, which is a ground-up redesign. I picked it up and gave it a quick whirl this evening and they've done an amazing job emulating the 101. The sequencer can get you close to MC-202 territory as well, complete with slides. For a limited time, you can pick it up for only $40 (the regular price will be $60).
