CONNECTIONS

BASIC MIDI HOOKUP

MIDI is an internationally-accepted protocol that allows musical-related data to be conveyed from one device to another. See the MIDI Supplement in Appendix B if you are not familiar with how MIDI works.

The QS has three MIDI connectors which provide the following functions:

MIDI IN

This port is for receiving MIDI information (notes, program

 

 

changes, etc.) from a source such as another QS or MIDI

 

 

keyboard, controller, or computer.

MIDI OUT

This port is for transmitting MIDI information to another MIDI

 

 

keyboard, sound module, or computer.

MIDI THRU

This port is for passing on (echoing) MIDI information received

 

 

by the MIDI IN port. In simple MIDI setups, the THRU port is

 

 

used to connect additional devices that will all be “listening” to

 

 

the same source.

To play the QS from a MIDI control device (keyboard, drum pad, guitar or bass controller, sequencer, etc.), connect the control device’s MIDI OUT to the QS’s [MIDI IN]. The illustration below depicts a master QS connected to a slave QS. When both are set to a common MIDI channel, you can hear both when playing the master QS’s keyboard.

The QS’s [MIDI OUT] connector sends MIDI data from the QS’s keyboard to other MIDI devices, but can also send System Exclusive data (see the MIDI supplement) to a storage device for later recall.

If you are using the QS in the middle of the MIDI chain (example: as the second unit of a three device chain), connect the QS’ [MIDI THRU] to the third device’s MIDI IN connector in order to route the first device’s MIDI out information to the third device.
