This video shows to program a Roland TB 303 and Roland TR 909 drum machine.
Another howto, this time for a Roland TB-303 Bassline and a TR-909 Rhythm Composer. For the 303 I used the pattern from Fatboy Slim’s song: “Everybody needs a 303”.
The 909 pattern is a quite simple Kick, Snare and Hihat pattern.Future Retro Mobius sequencer is master midi clock and the 303/909 follow as slaves. The 303 is connected via a Doepfer MSY2 converter.
