Modded Roland TR-606


via this auction

Funny pots.

"This auction is for a malfunctioning Roland TR-606 drum machine. The machine has been modified by a previous owner for individual voice outputs and voice tuning controls and has been altered from its original condition.

When it was working the modified machine functioned flawlessly, all original and modified outputs and DIN sync worked, all original and modified knobs, switches, and buttons worked. The machine had worked trouble free for the last 6+ years and has only recently experienced the issues described below.

Currently the 606 will power on, all voices seem to be working and it can be coaxed into a limited sort of functionality. The sequencer will run and it will output sound but the sequencer behaves erratically and associated button presses and mode knobs do not always respond as expected. The sequencer will vary length depending on button presses. Phrases and partial patterns might be able to be produced but not without random and unpredictable behavior.

The non-sequencing knobs (tempo, volume, etc) all work. The lights all work and the machine exhibits its classic pleasing all analog sound even in a broken state (I tested with headphones). The modified tuning controls and individual outputs all seem to be functional. Conceivably whatever output can be achieved could still be captured for sampling or other creative use even if a full repair is not possible, ultimately this will be for the buyer to determine."
