Octave Up/Down; Transpose; Pitch Wheel; Modulation Wheel - Launchkey MIDI controller keyboard User Manual

English

Octave up/down

The Octave + / Octave - buttons [12] shift the keyboard 'up' or 'down' in octave steps. The
number of octaves over which the keyboard can be shifted varies with Launchkey model:
• Launchkey 25: -4 to +5 octaves
• Launchkey 49: -3 to +4 octaves
• Launchkey 61: -3 to +3 octaves
Note that the LED display will confirm the number of octaves shifted (as a positive or negative
value).

Transpose

Pressing the Octave + / Octave - buttons [12] together lets you transpose the keyboard in semitone
increments, up to a maximum of +/- 12 semitones. The LED display flashes, and confirms the
transposition.

Pitch Wheel

Launchkey's Pitch Wheel [2] transmits standard MIDI Pitch bend
messages; use it with synth software to vary the pitch of the played note.

Modulation Wheel

The Modulation Wheel [3] transmits standard MIDI Modulation messages
(CC=1); what effect these have on your synth sound will be determined by
how the synth has been configured.
Typically, a Modulation Wheel is used to vary a synth parameter such as filter
cut-off frequency or vibrato.
