"Quick and dirty video to showcase the Böhm Digital Drums i'm selling. [via this auction]

I just made this one to show the unit is fully working, both in performance and record mode.

For those who do not already know this unit it is usually described as the "German Linn Drum" but that is an understatement in my opinion. Sure you get some nice fat 12 bit drum samples and a sequencer that grooves a lot. But it is much more than that.

If you consider it simply as a drum machine from 1983 you would still be amazed by the features it provided back then: 32 user patterns each with fill, break, solo 2 bar and solo 4 bars = 180 possible personal composition in top of the 612 (yes) prerecorded ones, up to 32 bar length and 1/64 resolution, realtime or step recording, individual instrument volumes, automatic or random fills, per pattern or global tempo, sequencer mode, pattern copy and more...

But if you disregard the built-in 'arranger' then you're missing a lot from this great device.

It consists of a 4 part analog synth engine, fully programmable. No possible edition of the sounds but the 66 different presets do sound great. Some are even routed through a analog phasing module built around Panasonic MN3006 BBD chipsets.

You can record your own 5 tracks per pattern, with different bar lengths if you want, and even use the bass part to act as a simple mono bass synth with the provided keyboard !

Probably the most comprehensive unit of its time and genre."

This one has a very rare modification that provides individual outputs and volumes for the 4 synth parts.

It also has the cassette and trigger option fitted to save and load your patterns and tape sync to other gear.

There are more possible options and modifications for the unit, including 8 seperate outputs for drum sounds, MIDI, drum triggering and more.

It has been serviced and is fully working. Brand new battery was fitted so it's ready for some 40 more years of fat beats.

As it often is the case with such a drum machine you may experience double triggering with the pads but shouldn't be an issue.
