Aftertouch
The majority of contemporary MIDI keyboards are
capable of generating aftertouch messages. On this type
of keyboard, when you press harder on a key you are
already holding down, a MIDI Aftertouch message is
generated. This feature can be used to control the Cutoff
frequency of the Pulse 2.
Amount
Describes to which extent a modulation influences a
given parameter.
Amplifier
An amplifier is a component that influences the volume
level of a sound via a control signal. This control signal
is often generated by an envelope or an LFO.
Arpeggiator
An arpeggiator is a device that splits an incoming chord
into its single notes and repeats them rhythmically. Most
arpeggiators feature different sequence modes to cover a
wide range of applications. Typical controls for an ar-
peggiator are the octave range, the direction, the speed
and the clock, which means the repetition interval.
Some arpeggiators also feature preset or programmable
rhythm patterns.
Attack
An envelope parameter. "Attack" is a term that describes
the ascent rate of an envelope from its starting point to
the point where it reaches its highest value. The Attack
phase is initiated immediately after a trigger signal is
received, i.e. after you play a note on the keyboard.
Band Pass Filter
A band pass filter allows only those frequencies around
the cutoff frequency to pass. Frequencies both below
and above the cutoff point are damped.
Clipping
Clipping is a sort of distortion that occurs when a signal
exceeds its the circuitry maximum value. The curve of a
clipped signal is dependent of the system where the
clipping takes place. In the analog domain, clipping
effectively limits the signal to its maximum level.
