Someone knows how to make work together a microkorg with an sp404, synchronize, exact timing, specially trying to make bass sounds from the micro with sp404 drums; im into electropunk n digital hardcore, need help with this stuff + anyone using it with sonar? and how to do it?

you would need another sequencer... a laptop or Yamaha QY70 could do the job well;)

Or you can play your riffs on the micro korg and sample 'em in the 404.

since your 404 is midi out only, you will need something to clock them both(a midi master metronome like mmc or mtc). the microkorg can recieve and sync the delay and such. i don't know if you want to (can?) control the bpm from the mk though.
