Sound Parameters – Amplifier
Waldorf Q User’s Manual 96
Amplifier
This unit is almost the last part in the Q’s signal routing, only followed by the Effects section. Its
purpose is to set the volume of the sound.
To understand the operation of this unit, it is important to know that the Amplifier Envelope is always
acting as a modulation source for the volume. This means that an audio signal can only pass through
if the Amplifier Envelope is triggered and opened.
The following picture of the Q’s front panel shows the Amplifier section:

Volume
0…127
Determines the master volume of the sound program.
Velo -64…+63
Specifies how much volume will be affected by keyboard velocity. Use this feature to give more
expression to the sound. With a setting of 0, velocity will have no effect on the volume. Classic
organs work in this way because they do not have dynamic response. For positive settings, the
volume rises up to higher velocities. This is the most commonly used setting, which gives a piano-like
character. For negative settings, the volume falls up to higher velocities. This gives an untypical
character suitable for effect sounds. As the Amplifier always works in conjunction with the Amplifier
Envelope, this parameter actually determines the envelope velocity amount. The following picture
illustrates this functionality:
