Percussion Synth
whose decay time is controlled by the Speed knob. The Depth knob controls the
level of the noise. The pitch of the oscillator will not be modulated.
Envelope. The oscillator pitch will be modulated by a simple envelope, whose
decay time is controlled by the Speed knob. The Depth knob controls the amount of
pitch modulation. When using negative Depth settings, you may need to set the
oscillator Pitch fairly high.
Speed
0.0-100.0. The Speed control changes in meaning according to the Type selection.
With Saw, Square, Triangle, and Random, the Speed sets the frequency of the LFO.
With Noise EQ and Envelope, the Speed sets the envelope decay time.
Depth
0-100. The Depth control changes in meaning according to the Type selection. With
Saw, Square, Triangle, Random, and Envelope, the Depth sets the amount of pitch
modulation. With Noise EQ, the Depth sets the volume of the noise.
Noise Color
This section controls the timbre of the noise when the Type is set to Noise EG. It also
affects the sample-and-hold LFO when the Oscillator Pitch Mod Type is set to
Random.
Cutoff
0-100. This controls the cutoff frequency of a highpass filter dedicated to the noise
generator.
Resonance
0-100. This controls the resonance of the highpass filter.
Amplifier
Decay
0-100. This sets the decay time of the amplitude envelope. Higher settings mean a
longer decay time.
Bass Boost
0-100. This increases the bass frequencies in the output signal.
Level
0-100. This sets the overall volume level of the Patch.
