When we visited Berlin a couple of years ago Uwe George showed us a PCB that we imagine has evolved into these two little drum machines.
The Tanzmaus is the follow up to the MFB 503 drum machine, with 5 analogue drum voices and 2 sample based drums. With the ability to add your own samples in the future.
The Tanzbar lite is the follow up to the 522 drum machine. Based around an 808 sounding circuit, it gives you 10 drums.
Both drum machines have the same sequencer from the original Tanzbar, giving you parameter locks, and much more
