This is not the normal MC-4, this is the MC4-B - the 2nd version with expanded memory. Record like your favorite synth heros did in 1981, before MIDI! Or like Vince Clarke did again when he realized this thing's timing was way tighter than MIDI. This MC4 was state of the art when it came out and certainly remains a special tool today, thanks to its unique calculator style interface. Use this with your vintage Moog, ARP, Oberheim, Roland, Sequential Circuits and other vintage analog synths. This Roland MC-4 b is powerful enough to sequence four synths at once (use 1 channel for each monophonic part) or, you can use it with a modular synth and patch the CVs and gates to anything you want.
4 channels of:
external CV and gate in
tempo CV in
external sync in and out (1/8")
calculator style keypad - enter your notes and step times with numbers!
cycle - loop function
din sync in / out - sync it to your TB-303, TR-606, CR-8000, TR-808, TR-707, MIDI to DIN converter, etc.
CMT tape sync in / out
copy, insert, delete, replace
external control start / stop
