Master, MPE, and scope

A terse lookup for the master-section controls. See The Master band and MPE and MIDI-learn.

ControlWhat it doesRange / values
GainOutput volume.dB
ClipMaster-output safety clipper (a character stage): Off is bit-exact (can overshoot), Soft rounds peaks gently, Hard brick-wall clips to stop overs reaching the host.Off / Soft / Hard
LimiterMaster brickwall limiter: zero-latency, stereo-linked, sits last in the master chain so the output can never clip. Off is bit-exact.Off / On (default Off)
Limiter CeilingThe level the limiter holds the output below, in dBFS.-3 to 0 dBFS (default -1.0)
Limiter ReleaseHow fast the limiter’s gain glides back toward unity between peaks.30 to 500 ms (default 100)
QualityInternal oversampling rate: higher reduces aliasing on bright or distorted patches at a CPU cost.1x / 2x / 4x / 8x
Auto-HQForce maximum oversampling on offline render (bounce) while keeping the live setting for playback.Off / On

The summed-voice bus stage, both bypassed at zero.

ControlWhat it doesRange / values
GlueAnalog-summing saturation on the whole mix: near-clean when quiet, soft-compresses and shares one harmonic fingerprint across every voice as the mix runs hot (zero is bypass).0 to 100 %
WarmthShifts the Glue colour from purely odd toward an even-harmonic console asymmetry (only audible when Glue is up).0 to 100 %
SagModels the shared power rails drooping under heavy polyphony, so loud chords duck slightly then bloom back (zero is bypass).0 to 100 %
DepthHow far the rails sink at full load, the maximum duck of the Sag effect (only audible when Sag is up).0 to 100 %
TimeSpeed of the sag: fast is a snappy duck-and-bloom, slow is a loose, breathing recovery (only audible when Sag is up).fast to slow
ControlWhat it doesRange / values
MPEEnables per-note expression: each note carries its own pitch-bend, pressure and slide from an MPE controller, routable as per-note modulation.Off / On
Bend RangePer-note pitch-bend range in semitones; match it to your controller so slides bend the intended interval.1 to 96 semitones
ControlWhat it doesRange / values
SourceWhich point in the signal path the scope taps.Master / Pre-FX / Filter / Osc
Source 2A second overlaid trace from another tap point for comparison, or Off for a single trace.Off / Master / Pre-FX / Filter / Osc
ModeWave draws the signal over time; XY plots the two sources against each other (a vectorscope for stereo width and phase).Wave / XY
Trigger SlopeWhether the trace starts on a rising or falling crossing of the trigger level.Rising / Falling
Trigger LevelThe amplitude the trace waits to cross before it draws, stabilising a repeating waveform.signed
FreezeHolds the current scope trace.Off / On
TimebaseScope zoom over the time axis.zoom
