 +currently the sequencer has 2 MIDI IN and 2 MIDI OUT, but this is expandable to 4 IN and 4 OUT. The current LPC core board does not have the extra MIDI's on board.

 +A three digit led display shows the BPM like on the original TR-909. The BPM is controlled with an encoder.
 +A nice dogm graphical display is used as LCD

 The patterns can be for example 32 steps long with 3 trigger layers (gate, accent, roll, ....) and 2 parameter layers(velocity, roll, roll2, ...) The patterns can be for example 32 steps long with 3 trigger layers (gate, accent, roll, ....) and 2 parameter layers(velocity, roll, roll2, ...)
