DOEPFER MIDI TO SYNC INTERFACE MSY2 User's Guide (English) www.doepfer.
INTRODUCTION 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. The SYNC standard is used in vintage drum computers or sequencers such as the Roland TR808 rhythm composer or the TB303 bass line. SYNC-CLOCK is a periodic TTL signal (0/+5V) representing the tempo. SYNC-START/STOP is a signal that indicates on the 2 possible states: START = +5V, STOP = 0V.
If desired you may connect the Clock output jack to the control input of another device (e.g. the arpeggiator control input of a synthesizer or a drum machin with separate Clock input) to control it with a MIDI synchronized Clock signal. Use a suitable cable. Normally a cable with a 1/4" mono jack plug on one side (device) and a 3.5mm miniatur mono jack plug (MSY2) on the other side will be used. POWER SUPPLY MSY2 does not have a built-in power supply.
Pay attention if you open and close the MSY2 case. Use only a suitable screw driver. We cannot take back units if the case or LEDs are damaged and the warranty will be lost during such manipulations. If you are not sure whether your are able to do the modification send the unit to your local dealer or to Doepfer Musikelektronik, Graefelfing (Germany). The external power supply (AC adapter) is NOT included with the MSY2 and must be purchased locally by the user.
DIP switch 1 2 3 4 Valence "off" 8 4 2 1 Valence "on" 0 0 0 0 Picture 3: Valences of DIP switches for Clock dividing factor The valence of the switches increase in the 2's power rule (1, 2, 4, 8). To obtain the resulting dividing factor you have to add 1 to the calculated value from the table above. Example: To obtain a dividing factor of 6 you have set the switches 2 and 4 to "off" and the switches 1 and 3 to "on". This results in the valences 0+4+0+1 = 5. If you add 1 you get the resulting factor 6.
