Logic Pro Retro Synth global settings
Retro Synth global controls are used to set the overall tuning, polyphony, and other aspects
of your instrument.
The controller settings let you assign MIDI keyboard features to Retro Synth controls. You
can use three MIDI controllers—velocity, modulation wheel, and aftertouch—to change
Filter Cutoff, Wave Shape (Pulse Width), or LFO/Vibrato Rate controls. Multiple MIDI
controllers can be assigned to the same control, so you could change filter cutoff with both
velocity and aftertouch, for example. Alternatively, a single MIDI controller can be assigned
to multiple Retro Synth parameters—with aftertouch affecting both filter cutoff and LFO
speed, for example.
If you’re new to synthesizers and the concepts behind modulation controls, see
Synthesizer basics overview.
Click the Settings label to switch between the modulation and global/controller controls.
Global parameters
• Transpose pop-up menu: Choose a value to transpose Retro Synth ±2octaves.
• Tune field: Click the arrows or drag vertically to tune Retro Synth in semitone steps.
• Bend pop-up menu: Choose a value to set the maximum upward/downward pitch bend.
Pitch bend modulation is typically performed with your MIDI keyboard pitch bend wheel
or joystick.
• Polyphony pop-up menu: Choose the maximum number of notes that can be played
simultaneously (up to 16) or run as a monophonic synthesizer.
• If you choose legato and play in a legato style (strike a new key while holding
another), the envelope generators are triggered only for the first note you play
legato, and then they continue their curve until you release the last legato played
key. This means that if you play legato, a portamento occurs (the portamento time is
set with the Autobend / Glide Time control). If you release each key before pressing a
new one, the envelope is not triggered by the new note, and there is no portamento.
• If you choose mono, staccato playing retriggers the envelope generators every time
a new note is played.
• Voice Detune field: Click the arrows or drag vertically to tune Retro Synth in cents
(1cent=1/100th semitone).
• Stereo Spread field: Click the arrows or drag vertically to set the amount of voice
panning, relative to the center position. Spread: 0=mono, 1=full left/right panning.
Voices are panned left or right in an alternating, symmetrical pattern.
Note: Detuning and panning works in Single and Double voice mode. In Double voice
mode, detuning and panning affects the respective voice pairs.
