Alesis QS8.1, QS7.1 manual

Part 1: Setup & Connections

∙As Controller. To play other MIDI devices from your QS, run a MIDI cable from the QS’s [MIDI OUT] jack to the MIDI IN of the device you want to control.

∙As a Link in a “daisy chain.” If you are using the QS in the middle of the MIDI chain (example: as the second unit of a three device chain), you’ll need two MIDI cables. Attach one from the MIDI OUT of the chain’s first device to the [MIDI IN] jack of the QS; and then attach the other from the QS’s [MIDI THRU] jack to the MIDI IN of the chain’s third device.

∙As part of a computer-based MIDI Network. If you are using a computer for sequencing and/or programming, you’ll want to be able to play data into your computer from your QS, and receive data back as well. This will take two MIDI cables. Attach one from the MIDI OUT of the computer’s MIDI interface to the [MIDI IN] jack of the QS; and then attach the other from the QS’s [MIDI OUT] jack to the interface’s MIDI IN.
