Alesis QuadraSynth Plus manual Controllers a D Assignment, Reset Controllers a D

Global Settings: Chapter 8

In Page 2 of Global Edit mode, Quad Knob [4] selects the Keyboard Mode (NORMAL, CH SOLO, OUT 1 – OUT 16). This determines how the keyboard will function. When in Mix Mode, you have the option to transmit on several MIDI channels at once, or to temporarily isolate certain channels within a Mix.

NORMAL. In Program Mode, the keyboard will transmit on the selected MIDI channel. In Mix Mode, the MIDI channels the keyboard transmits on will correspond to whatever layers or splits the Mix is set up for. Note that certain controllers such as pitch bend and aftertouch may transmit on a different set of channels, since they are enabled or disabled independently for each channel of the Mix The MIDI Monitor indicators in the display will show which channels are active.

CH SOLO. In Program Mode, this is the same as the NORMAL setting. In Mix Mode, the only sounds coming from the QuadraSynth Plus, and the only MIDI messages, will come from the layer or range of the underlined MIDI channel in the display. This allows you to isolate individual channels in a Mix. So, if you play in a range of the keyboard that is active on MIDI CH 1, and 1 is underlined, you'll hear it. All other ranges or layers will not respond to the keyboard (they will respond to incoming MIDI messages on their respective channels). Use the MIDI [♦] and [∅] buttons to hear each channel in turn.

OUT 1 – OUT 16. In both Program Mode and Mix Mode, the keyboard will transmit on a specific MIDI channel (determined by the number setting of this parameter), but it will not play the internal sound(s). Use this mode if you're using a MIDI sequencer with an “Echo” feature (also known as “MIDI Thru”); the sound will be activated by messages appearing at the MIDI IN connector after it’s made the “round trip” through the sequencer. This is the QuadraSynth Plus’s equivalent to LOCAL OFF.

Controllers A – D Assignment

The QuadraSynth Plus allows you to assign up to four general purpose MIDI controllers. These MIDI controllers are assigned a letter, A–D. In Page 3 of Global Edit mode, you can choose which MIDI controllers (0 to 120) to assign as Controllers A, B, C and D. For a listing of all MIDI controllers and their designations, see page 123 in the MIDI Supplement towards the end of this manual.

Reset Controllers A – D

Found on Global Edit Page 4, the “A–D Reset” function (On/Off) determines whether the values for Controllers A–D will be reset to zero when a new Program or Mix is recalled. Use Quad Knob [2] to turn this on or off. This parameter works along with the A-D Mode parameter (described below) to choose how the keyboard is being used as a controller. If the A-D Controllers are being used to modulate the volume, etc., of external MIDI sound modules, you will probably want the A-D Reset parameter turned “OFF” so that the modules’ volumes will not be reset to zero every time a new Mix or Program is selected. If you are using the A-D Controllers only for modulating parameters in the QuadraSynth Plus, you will probably want this parameter turned “ON” so that new Programs or Mixes are recalled with their stored settings.
