This one took a LOT of work but i got there in the end. If you've read my TR606 rants elsewhere you probably know about the Boss DR110. It was Roland's last analogue drum machine and sound-wise it is very very similar to the Roland TR-606 only about £150 cheaper and has LCD grid programming.
Thats not a midi socket, the standard DR110 has no way to sync it to other kit so i installed a DIN sync interface round the back of the mod box. Theres even a bright blue LED to show when the DIN sync is active.
