Keyboard Sensitivity (QuadraSynth only)
In Page 2 of Global Edit mode, Quad Knob [1] adjusts how sensitive the keyboardÕs
velocity will be (00 to 99). When set to 0, the keyboard will not transmit any velocity,
no matter how hard or soft the keys are played; all notes will be treated as having a
velocity of 64 (right in the middle). When set to 99, the keyboard will have maximum
sensitivity, allowing the greatest difference between soft and loud notes in terms of
velocity control. Adjust this value to create the ideal sensitivity for your playing
style. By lowering this value from 99, you limit how loud and soft notes may be
played.
Keyboard Curve (QuadraSynth only)
In Page 2 of Global Edit mode, Quad Knob [2] selects the Keyboard Velocity Curve.
There are three options: Weighted, Plastic and Maximum. When set to weighted, the
keyboard will have the velocity response of a weighted keyboard. This means you
will really have to play hard to get the loudest notes. When set to plastic, the
keyboard will have the velocity response of a typical plastic keyboard. Plastic is not
as sensitive as Weighted, therefore playing soft will not result in the same soft notes
as Weighted mode produces. When set to Maximum, no velocity response is
available, and all notes are given a maximum velocity value of 127. This parameter
only affects the keyboardÕs output to the sounds in the QuadraSynth and MIDI Out.
This is different from the Velocity Curve parameter in Program Edit, which
determines how a sound will respond to incoming velocity information, either from
the keyboard or from MIDI In.
Keyboard Transpose (QuadraSynth only)
In Page 2 of Global Edit mode, Quad Knob [3] controls Keyboard Transposition (-12
to +12/up or down 1 octave). This determines the note number that the keyboard
will transmit to the QuadraSynthÕs sounds and to MIDI Out. If you are using a MIDI
sequencer, use this function when you wish to record notes outside of the keyboardÕs
normal note range (note numbers 28Ñ103). When set to -12, the keyboard range is
note numbers 16 Ñ 91. Likewise, if set to +12, the range would be 40 Ñ 115.
Keyboard Mode (QuadraSynth only)
In Page 2 of Global Edit mode, Quad Knob [4] selects the Keyboard Mode (FRM MIX,
CH SOLO, OUT 1ÑOUT 16). This determines how the keyboard will function when
using Mix Mode only (when using Program mode, use the MIDI [¬] and [®]
buttons to set the MIDI OUT channel for the whole instrument). But when using the
QuadraSynth in Mix Mode, you have the option to transmit on several MIDI
channels at once, or to temporarily isolate certain channels within a Mix.
FRM MIX. The MIDI channels sent out will correspond to whatever layers or splits
the Mix is set up for. For example, in Preset Mix 01 (ÒFour ZonesÓ), the keyboard is
split 4 ways from left to right; each ÒzoneÓ is linked to a different set of four
channels. As you play through each zone, it will send MIDI messages corresponding
to that key range and trigger the corresponding channels. Note that certain
controllers such as pitch bend and aftertouch will send on all channels at once. The
MIDI Monitor indicators in the display will show which channels are active.
