Voluum

Owner’s Manual

When triggered by a new note or chord, the volume increases from lo to hi (attack). Once complete,

the volume then decreases (decay) to the sustain level (sustain). Once the input signal falls below

the threshold (it drops in level by thr dB compared to the signal level at the start of the attack) the

release phase is entered and the volume falls back to its lo value.

Using this

ADSR

shaping, you can achieve sounds reminiscent of other instruments by emulating the

characteristic shape of their envelopes. For example, a slow attack can be used to emulate bowed

stringed instruments.

Adjusting the limiter

The limiter is used to limit the range of the output signal in order to prevent the potential overload of

any downstream equipment with limited headroom, such as a digital processor. Unlike the

compressor, the limiter always reacts instantly and so can prevent overload caused by very fast

transients that the compressor could miss.

Top Tip: For simplicity, we described how curves affect the footpedal, but they also affect

how the volume changes in fade mode, under

MIDI

control and in envelope

mode. Don’t worry too much about this — simply adjust Cur to get the sound

you want!

Parameter Controllable Range Description

dBu yes −5·2 –20·0 The nominal level at which the limiter clips, in dBu.

SyM yes −99–99

The limiter symmetry in percent — 0 is symmetric.

Positive values allow the positive part of the signal to be

larger than the negative part.
