Doepfer MSY2 MIDI-to-SYNC/Clock Interface

- MSY2 has 2 SYNC jacks connected in parallel and a clock jack (3.5mm jack). The clock signal (0/5V pulses) and the start/stop signal (start = +5V, stop = 0V) are available at the SYNC sockets. The clock signal is also routed to its own clock socket, e.g. to control the arpeggio control input of a synthesizer MIDI-synchronously.

- The SYNC/MIDI clock divider factor can be set between 1:1 and 1:16 via externally accessible DIP switches. With a divider factor of 1:1 (i.e. each midi clock event generates a clock pulse), the pulse width of the clock output has a fixed value of approx. 4 milliseconds. With divider factors greater than 1, the pulse width corresponds to the selected divider factor. In addition, the polarities of start/stop and clock can be selected via 2 additional DIP switches. The divider factor indicates after how many MIDI clock commands a new SYNC clock is triggered.

- The polarity switches determine whether a +5V or a 0V level indicates the active state of Start/Stop or Clock. In addition to the standard application of the MSY2 (control of devices with the Roland-compatible SYNC socket)
other failed controllers are also possible.

- SYNC clock and SYNC start/stop are displayed optically via 2 LEDs.

- MIDI In, MIDI Thru

- MSY2 is housed in a stable metal housing (approx. 60 x 60x 35 mm) made of 1 mm sheet steel, the housing color is black.

- Power is supplied via an external plug-in power supply unit (7...12V/100mA). If the MIDI transmitter used corresponds 100% to the MIDI standard, the power supply can also come directly from the MIDI line (i.e. no separate power pack required). In this case, a jumper (plug-in bridge) must be implemented in the device. However, this type of power supply is not possible in connection with all MIDI devices and must be tried out on a case-by-case basis! The internal jumper for the power supply version is therefore provided ex works.
