Alesis QSR 64 manual Polyphony In Mix Play Mode, Playing A Group Of Channels In A Mix

Editing Mixes: Chapter 5

POLYPHONY IN MIX PLAY MODE

The QSR has 64-note polyphony. In Mix Play Mode, if you have all 16 MIDI channels assigned to the same keyboard range, and each channel’s Program has only one active Program Sound, you’ll have 4-note polyphony as you play the keyboard (but a really thick layer...). This is extreme, of course, but should tell you what you can expect when you really pile on the layers from the keyboard.

PLAYING A GROUP OF CHANNELS IN A MIX

In Program Play Mode, you can use the [ ▲ MIDI CH ▲] buttons to set the MIDI IN channel for the whole instrument. But when using the QSR in Mix Play Mode, you may need to be able to transmit on several MIDI channels from your MIDI keyboard, in order to play the different channels within a Mix. However, there is a way to “group” any number of channels in a Mix to all play simultaneously from a single MIDI channel (in addition to responding to MIDI information on their individual channels). This can be done by combining the Group parameter (found in Mix Edit Mode, Keyboard/MIDI Function, Page 3) and the Mix Group Channel function (found in Global Edit Mode, Page 13).

➀From Mix Play Mode, press [EDIT] followed by BANK SELECT [UP] (also labeled [GLOBAL]).

➁Turn the [VALUE] knob to get to Page 13.

You will see "MixGroupCH: " in the middle of the display.

➂Press the [CURSOR ▲] button once to advance the cursor in the display, and turn the [VALUE] knob to set the Mix Group Channel between 1 and 16, or Off.

1–16.When the Group Mix Channel parameter is set between 1 and 16, the number it is set to determines the single MIDI channel which, when MIDI information is received on it, will play the channels in the selected Mix which have their Group parameter turned on.

OFF. In this mode, the individual channels used by the selected Mix will only be triggered by MIDI information received on its designated MIDI channel (Example: the sound on channel 1 will only respond to information received on MIDI channel 1, the sound on channel 2 will only respond to information received on MIDI channel 2, etc.), regardless of whether each channel’s Group parameter has been turned on or off. However, the MIDI In parameter for each channel must be turned on in order for that channel to respond to incoming MIDI information on its own channel.
