doepfer msy2 midi-to-sync interface (black) price : $140.00   doepfer midi schulz kabel (all 5 pins wired - also works as a din sync cable) price : $10.00

msy2 is an interface that converts the midi realtime events clock, start and stop into the corresponding signals clock and start/stop of the sync standard. this standard was used e.g. in the roland devices tb303 bass line or tr808 rhythm composer.

msy2 is equipped with 2 sync din sockets (switched in parallel), a clock miniature jack socket (3.5mm), midi-in and midi-thru. sync-clock is a periodic signal (0/+5v) representing the tempo. sync-start/stop is a signal that indicates one of the 2 possible states: start = +5v, stop = 0v. the clock pin of the sync standard is additionally available from a miniature jack socket e.g. for synchronizing the arpeggio input of an analog synthesizer with midi.

msy2 enables the 1:1 conversion of midi clock to sync clock (i.e. 1 midi clock triggers 1 sync clock pulse), as well as the reduction of the tempo by dividing the incoming midi clock frequency by an integer factor. the factor can be set to any value between 1 and 16 with a dip switch at the bottom of the msy2. a factor 1 corresponds to the 1:1 conversion, 16 is the maximum of frequency reduction, i.e. after 16 midi clocks 1 sync clock appears.

with two other switches the start/stop polarity and the clock polarity can be changed for special applications not following the sync standard.

clock and start/stop are displayed with 2 leds.

midi-in, midi-thru

msy2 is built into a stable metal case (about 60 x 60x 35 mm).
