This thing is going to be a beast. If you are in the market for a hardware sequencer you are going to want to check this one out. One thing I really like about the Mattson SQ816 is the individual gate outs for each step. You can have a 16 step sequence with the main out driving the main sequence while having each step drive different drum modules. In essence you get a main melody sequencer as well as 16 drum triggers. You can of course gate anything including non percussive sounds. The sequencer also supports MIDI out.
