Compressor Block - Physis Piano H1 Reference Manual

−
Percussion Decay: decay time of an electromagnetic organ's percussion. The higher the value, the longer the decay
time.
−
Percussion Level: percussion level of electromagnetic organs. The higher the value, the higher the level.
−
Presence: sound presence; it simulates the dynamic of wind instruments. The higher the value, the stronger and richer
the sound.
−
Release Detune: magnitude of tuning variation (to lower pitch) after a key has been released. The higher the value,
the stronger the detuning.
−
Release Time: time it takes for the sound to decay, after a key has been released. The higher the value, the longer the
decay time.
−
Release Noise: loudness of the hammer's noise (or finger's, in string instruments such as bass, double bass, guitar)
when a key is released. The higher the value, the louder the release noise.
−
Stretching Tune: deviation from ideal tuning (corresponding to the equal temperament), according to a frequency
distribution known as Railsback curve. In this way, low-pitched notes are slightly lower, while high-pitched ones are
slightly higher. The higher the value, the stronger the deviation.
−
Sustain Level: signal level during the Sustain phase of the sound. The sustain phase begins shortly after pressing the
key and end when the key is released. The higher the value, the higher the sustain signal.
−
Sweep Depth: modulation depth of the cutoff frequency of the brightness filter. The higher the value, the deeper the
modulation.
−
Sweep Rate: regluates the modulation speed of cutoff frequency of the brightness filter. The higher the value, the
faster the modulation.
−
Velocity Filter: controls the influence of the dynamic, i.e. the pressure on the keyboard, on the cutoff frequency of the
brightness filter. The higher the value, the more sensitive the keyboard.
−
Vel. Percussion: controls the influence of the dynamic, i.e. the pressure on the keyboard, on the volume of the
percussion noise on electromagnetic organ Sounds. The higher the value, the more sensitive the keyboard.
−
Velocity Sens.: controls the influence of the dynamic, i.e. the pressure on the keyboard, on the volume. The higher the
value, the more sensitive the keyboard.
−
Vibrato Depth: modulation depth of the
−
Vibrato Rate: modulation speed of the

2.2 COMPRESSOR Block

How to access: press [SOUND EDIT], select the COMPR. block.
Description: these parameters control the Compressor effect. The
Compressor shrinks the dynamic range of the original signal. Its purpose is to
adapt the signal to be processed by the following blocks, or simply to modify
the sound's character.
−
Thres. (dB): sets the signal level, also called theshold, by dB; the compressor only
works above the Threshold.
−
Ratio: sets the quantity of compression of the dynamic range of the signal. It works
based on a direct proportion. For example, if the compression rate is 1:1 there is no
compression at all; with a compression rate of 3:1 the signal is three times more
compact than the original.
