Alesis QS7 Semitone -24 to +24 semitones, Detune -99 to +99 cents, Detune Type Normal or Equal

Chapter 6: Editing Programs

PITCH

The Pitch function (press [60]) lets you control the pitch aspects of each sound layer.

Semitone (-24 to +24 semitones) Page 1

Sets the oscillator pitch in semitone steps, from -24 (transposed down two octaves) to +24 (transposed up two octaves).

Detune (-99 to +99 cents) Page 2

Sets the oscillator pitch in cents, from -99 (transposed down 99/100 of a semitone) to +99 (transposed up 99/100 of a semitone).

Detune Type (Normal or Equal) Page 3

With Normal selected, the percentage of detuning remains the same over the entire range of the keyboard, so the effects of detuning sound the same no matter which key you play. With Equal selected, the absolute amount of detuning remains the same over the entire keyboard, so any detuning seems less pronounced as you play higher up on the keyboard.

Pitch Wheel Range (0 to 12 semitones) Page 4

Determines the maximum amount of pitch bend when the [PITCH] wheel is full forward. Example: When set to 12, the pitch wheel will bend ±1 octave (12 semitones).

Aftertouch Depth (-99 to +99) Page 5

At +00, aftertouch has no effect on pitch. Applying aftertouch (by pressing harder on the keyboard, or via MIDI messages) with this parameter set to a positive value raises the pitch; conversely, applying aftertouch through a negative value lowers the pitch. The higher the number (either positive or negative), the greater the amount of pitch change for a given amount of aftertouch.

Pitch LFO Depth (-99 to +99) Page 6

At +00, the pitch LFO has no effect. Higher positive values increase the amount of Pitch LFO modulation. Negative values give the same apparent effect, but with reversed LFO phase (i.e., if the pitch would normally be increasing with depth set to a positive number, the pitch would instead be decreasing at that same moment had the depth been set to a negative number). Pitch LFO parameters (such as speed and wave shape) are programmed within the Pitch LFO Function (see page 72).

Pitch Envelope Depth (-99 to +99) Page 7

At +00, the Pitch Envelope has no effect. Positive values raise the pitch from the baseline according to the envelope shape, while negative values similarly lower the pitch (see illustration below). The higher the number (negative or positive), the greater the effect. Pitch Envelope parameters (such as attack and decay time) are programmed within the Pitch Envelope Function (see page 61).
