Real-time Controller Knobs

Knob Functions Quick Edit mode

The Real-time controller knobs provide direct control of the PX-7’s synthe-

sizer parameters when the Controller Function Select is set to Quick Edit.

There is an LED next to each of the control knobs which illuminates to

indicate that the knob setting has been changed from the value

programmed in the preset (“Knobs Preset Quick Edit” mode must be

enabled in the Controllers menu). If the knob position is returned to the

original setting, the LED is extinguished.

Quick Edit knob

movements can be recorded into

the sequencer using realtime

song or pattern record modes.

Initial controller values can be stored in every preset. When you move a

knob with Quick-Edit enabled, the Initial Controller Value is updated with

the knob’s new value. The knob’s LED lights indicating that the preset value

has been changed. The MIDI A-P values are stored in the corresponding

Initial Controller Amount parameter in the Preset Edit menu (see “Initial

Controller Amount” on page 238). The Save/Copy button LED ﬂashes to

remind you that the preset has been edited. “Quick-Edits” made to a preset

are lost if you select another preset before saving them.

The four rows of knobs always control the preset on the basic MIDI channel

(the channel showing on the preset select screen), when the control switch

is set to Quick Edit.

The labels (Filter Cutoff, Filter Q, Filter Attack, Filter Decay, etc.) printed on

these rows show how the factory ROM presets are programmed to respond.

(The controls may not exactly conform to the front panel labels depending on the

preset.) You can change the way a preset responds to MIDI A-P messages

from the Preset Edit menu (PatchCords). The knobs only generate a

message when you move a knob to a new value. The current value jumps to

the new value.
