Roland CR-78 with rare Future Retro Din Sync / Programmer Box

via this auction
"The programmer/sync box was custom made by Future Retro (1 of only 2 ever made), and allows you to do the following...
* Sync the CR-78 to any other Din Sync device
* Select the playback sync rate to: (1) normal speed, (2) double speed, (3) half speed
* Use external positive polarity Gate or Trigger signals to programm patterns into the CR-78 user memory.
* Manually tap a beat into the CR-78 user memory using the momentary switch on the front panel.
* Front panel blue LED lights to show when external gate or trigger signals are being received.
* Sync box is powered using a 9v battery (included)
* Instructions for using the sync box will be included with the item.

We have tested the Sync/Programming of the CR-78 using the Roland TR-808, TR-606, and Future Retro Revolution.

Programming from one of these devices is simple. By syncing the playback of the CR-78 to your Din Sync master, you can then send the programmable trigger or gate signals out of the master into the programmer interface and on to the CR-78 for storing your own custom rhythms in the CR-78. When using a Din Sync master device which also has MIDI such as the Revolution, you can then sync your CR-78 to any other MIDI sequencers as well."
