The Expert Sleepers ESX-8GT is an expansion module for the ES-4, ES-40 or ES-5, adding 8 on/off outputs for use as gates, triggers, clocks etc. from one expansion header.
The ES-4/5 Controller software (part of Expert Sleepers Silent Way) also allows the ESX-8GT outputs to be used for DIN sync or MIDI output*(note – not just MIDI clock output, but as an actual MIDI port, capable of sending any MIDI messages). Since these outputs are driven from an audio connection, they have sample-accurate timing, which no USB MIDI interface can claim.
Power is supplied by the hosting ES-4/5/40 module, and is used for the LEDs only. I.e. with no LEDs lit, the current draw is 0mA.
Power: 20mA @ +12v / 0mA @ -12v
