MIDI: Part 5

TRANSPOSING MIDI NOTE NUMBERS PER ZONE

You can transpose different zones on the QS’s keyboard so they send higher or lower MIDI note numbers to external MIDI devices than you are actually playing.

Here’s how: Once the initial conditions are met (MIDI Out set to ON, Keyboard and MIDI In set to OFF), all you have to do from within Mix Edit mode is press the Pitch function button [70] and “tune” the external MIDI devices as if they were internal Programs using pages 1 and 2. That’s it!

Between the Octave and Semitone parameters (pages 1 and 2, respectively), this gives you a +/- 3 octave control over your other gear in any zone! And even if your external MIDI devices are being transposed in this manner by the QS, they will follow the [TRANSPOSE] button even further up or down.

Combine this with the multi-octave range of your QS and that means there isn’t any note you can’t reach in the entire MIDI specification of 128 possible notes! Now you see why we think the QS is such a powerful controller.

SENDING CARD SEQUENCE DATA TO EXTERNAL DEVICES

There is an option box in Sound Bridge which allows you to set up the sequences on a given card so they will be transmitted from the QS’s MIDI Output jack. Basically what it does is toggle the QS’s MIDI Out parameter between Out and Thru (Global Edit Mode, page 16).

A setting of OUT causes Card sequence data to play QS Programs only, while allowing the MIDI Out jack to function relatively normally (so you can play your MIDI gear from the keyboard while the sequence is playing).

A setting of THRU passes sequence data on to external MIDI devices from the MIDI Output jack of your QS, allowing both QS Programs and sounds from other MIDI devices to be played from a Card sequence. You will be able to play QS Programs from its keyboard, but you will not be able to play external MIDI devices while the sequence is running.

Note: It is highly inadvisable to enter Global Edit mode and toggle between these two settings while a sequence is running. If this happens, the QS could inadvertently send large bursts of data to your external MIDI devices.
