A synchronization method developed by Roland around 1980. A DIN sync cable carries two signals, a gate signal that tells the slave device to start or stop, and another signal that sends short timing pulses. Under the Roland standard, the pulses are sent at the rate of 24 pulses per quarter note (same as the MIDI clock message rate), although some Korg drum machines use 48 pulses per quarter note.

Unfortunately the DIN sync standard calls for a cable that uses the same connector as a standard MIDI cable, which often leads to confusion. The pinout is different and a MIDI cable will usually not work as a DIN sync cable, or vice versa. Fortunately, at least the standards are arranged so that connecting a MIDI output to a DIN sync input, or vice versa, will not cause any damage; it just won't work.

History[edit | edit source]

It was introduced by Roland Corporation for the synchronization of music sequencers, drum machines, arpeggiators and similar devices, as part of the Digital Control Bus protocol. It was introduced in 1980 with the Roland TR-808, followed by other Roland equipment in 1981, including the CR-8000, TR-606, TB-303 and EP-6060. It was the basis for the MIDI interface, released in 1983, which eventually superseded it.[1]

Devices with DIN sync[edit | edit source]

Some devices have a DIN sync input as well as DIN sync output, other device have only a single DIN socket which sometimes can be switched between input and output.
