Keyboard Magazine "In The Studio" Sync Tone and Click Track on Tape
There are many misconceptions concerning interfacing sequencers, drum machines and synthesizers to a tape recorder. The key to making them sync up with a tape recorder is the sync tone. The Linndrum, DMX, DSX, Drumtracks, TR909, MSQ700, Microcomposer 202, MPU-401, Drumulator, RX-15,RX-11, MXR , Polysequencer, SCI/Commodore 64 sequencer, PPG Wave 2.2 & 2.3 and the Oberheim DX (with a mod ) can all generate a type of sync tone called FSK. Each one of the above mentioned units can read this tone after it has been printed on tape and sync up again to it.
