MFB Urzwerg Pro Mk 2 CV+MIDI Sequencer SN 13358

via this auction

"Super sequencer from MFB
2 Run-modes offering 2 x 16 or 4 x 8 steps 32 skip-switches
32 LEDs
Polyphonic and monophonic MIDI-output
4 Available note quantize modes
4 x CV/Gate-outputs

Only used in studio. Immaculate condition, discontinued

I used this with a small modular setup as well as some synths (Roland SH101, Sequential Pro One) using MIDI and CV-Gate.

Either 2 sequences of 16 steps or 4 sequences of 8 steps. This makes possible to play up to four synthesizers or four channels of a multi-timbral synthesizer. It´s also possible to play a synth up to four-fold polyphonic. In duophonic mode the two remaining rows can modulate velocity and mod-wheel parameters (MIDI CC 01), in three-voice mode the forth row controls velocity.

Gate-Length (5 settings), CV range (0-10V) and Glide are controlled separately for rows 1 2 and 3 4. Range from 0-5V can be quantized, four scales are available.

Per step there is a skip button which either skips the entire step or just de-/activates the gate signal for this step, depending on the mode. Running direction and sequence length can be set separately for each row. The new random function allows random playback of steps. The auto-glide function activates glides only when two or more notes are tied, similar to the 303´s sequencer."
