ULTRA RARE! MADE IN STOCKHOLM April 26, 1985 year.

posted recordings [MP3] of the EPROMs here



http://m.matrixsynth.com Rare vintage Clavia ddrum with 6 voice cards. Each voice card uses an 8-bit EPROM cartridge that can hold up to 4 drum sounds on each cartridge and depends on the cartridge. 
Each voice card accepts a trigger input, with both a pitch and sensitivity knobs, and provides a hi-quality balanced output. Each voice also has a Decay knob to adjust the sample playback length, and two analog filters (Bass and Treble) that sound fantastic. There is also a selector switch section for each voice that allows you to select from sounds 1-4 depending on the cartridge used.

The ddrum has been fully tested, each voice card triggers properly and all knobs and selector buttons are confirmed working. Output is clean and strong with no scratchy pots.

There are some minor scratches on the ddrum case that I tried tpo capture in the photos, as well as one missing latch. Otherwise the ddrum rack/case is in good shape for its age.
