Beat Box - Korg Soundlink DRS OASYS PCI Patches & Effects Manual

Beat Box

Beat Box
This Patch combines two analog-style percussion synthesizers, similar to the
Percussion Synth, with a MIDI-synced sequencer.
To trigger the Beat Box from MIDI, set the Sequence Start/Stop parameter to Stop,
and then modulate this parameter with Note Gate. For best results, re-trigger the
Beat Box every few measures.
Percussion 1 and 2
The two percussion synth voices are identical to each other. They are very similar to
the Percussion synth, except that the initial phase and phase reset are preset.
Waveform
Triangle, Sine. This selects the waveform for the oscillator.
Pitch
0-100. This sets the tuning of the oscillator.
Pitch Modulation
Type
Saw, Square, Triangle, Random, Noise EG, Envelope. This selects the way in
which the pitch is modulated.
Saw, Square, Triangle. The pitch will be modulated by an LFO, with the specified
waveform. The speed and depth of the LFO are set by the Speed and Depth
parameters, below.
Random. The pitch will be modulated by a sample-and-hold LFO, with speed and
depth as set below. The sample-and-hold mechanism uses the main noise
generator, so that the Noise Color parameters will affect the LFO as well. The
Random setting gives especially interesting results with high Speed settings.
Noise EG. This adds noise to the output; you can control the timbre of the noise
using the controls under Noise Color, below. The noise has a dedicated envelope,
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.
