Master Volume Control & VU Meter
This is the master volume control for the Proteus X. This slider controls the output
volume of all MIDI channels.The range of this control can be adjusted using the
Headroom/Boost control in the preferences dialog box.
See page 18.
The VU meter indicates the overall output level of the Proteus X Main Outputs. It serves
as a handy indicator to show clipping or to troubleshoot audio output problems.
Tempo Control
This control and associated display sets the master tempo when the Proteus is chosen as
the tempo source. Proteus X contains a global master clock which is used for Tempo-
based Envelopes, Tempo-based LFOs, and clock modulation.
External Tempo Source" in the MIDI Preferences dialog must be Off for this control
to operate.
When "External Tempo Source" in the preferences dialog box is On, and an external
MIDI device or application is generating MIDI clock, the Proteus X tempo will lock to
the MIDI clock tempo.
Master Tune
Master Tune adjusts the overall tuning of all presets so you can tune Proteus X to other
instruments. The master tuning range is ±1 semitone in one cent steps (1/100th of a
semitone). A master tune setting of 0¢ indicates that the Proteus X is precisely tuned to
concert pitch (A=440 Hz).
Master Transpose
The master transpose parameter transposes the key of all presets in semitone intervals.
The transpose range is ±12 semitones (1 octave).
Limiter
When playing the Proteus X you may sometimes hear digital clipping. This clipping
occurs in the digital hardware and is not caused by the Proteus X, which uses high
resolution floating point processing and has tremendous internal headroom.
To avoid the clipping, you could always lower the volume controls, but there's a better
way. The Limiter monitors the signal ahead of the output stage and automatically turns
down the volume before clipping can occur.
