Split from Oxi Instruments is an efficient way to expand the MIDI connections of the ONE sequencer. The compact tool is first connected to the MIDI output of the ONE sequencer using the supplied cable. The main output 1 is now available as a normal MIDI socket, and there are also two further MIDI outputs in TRS format. A Thru socket is also available. The latter is useful in setups where the ONE is not the master sequencer. The three outputs can be selected as ports in ONE and each have 16 MIDI channels.
