"The MFB-Step64 is a step-sequencer with up to 64 monophic steps or 16 4-voice polyphonic steps. In monophonic mode it is possible to enter 16 steps with five parameters each, 32 steps with 3 parameters each oder 64 note on/off steps."

"The digital sequencer MFB-602 is an updated and expanded version of the legendary MFB-601. Use it to create sequences of up to 64 steps with individual note lengths and rests that are played back by the MIDI and CV/Gate output. One new feature is the ability to store 8 sequences in a set. There are even outputs for start and trigger."
In the U.S., I only see the MFB-Step64 available at Infant Noise, the U.S. distributor for MFB. Title link takes you to MFB.
