APPENDIX A: SYNTH TRACK PARAMETERS
In this appendix, the parameters of the synth tracks are explained.
OSCILLATOR 1
The OSC1 pages control the first oscillator, its sub oscillator, plus the noise generator.
OSC1 (page 1)
TUN (OSC1 Coarse Tune) sets the pitch of the os-
cillator in semi-tones. To jump a whole octave, press
the knob while turning it.
FIN (OSC1 Fine Tune) fine tunes the pitch of the
oscillator. This knob can be continuously tweaked
several turns. TUN is increased or decreased one
semitone for every turn on FIN.
DET (OSC1 Linear Detune) offsets the frequency
of the oscillator by a certain number of hertz (unlike
FIN, which adjusts the pitch in cents). This unique
feature gives more detune in the bass notes and
allows for a different kind of chorus-like detune that
reminds of very old and big analog synthesizers.
TRK (OSC1 Keytrack) sets the oscillator pitch to
follow the notes you play or not. When off, the pitch
is constant, which can be convenient for drum or
effects sounds.
LEV (OSC1 Level) sets the oscillator level. The nor-
mal level is 100. The sound can get dirtier at higher
levels; lower levels gives a cleaner signal through
the filters and also makes filter resonances more
pronounced. Try different levels for different kinds of
sounds.
WAV (OSC1 Waveform) sets the oscillator waveform
to Sawtooth, Transistor Pulse, Pulse, or Triangle. It
is also possible to choose one of the two External
Inputs (to send external sounds through the filters)
or to activate Filter Feedback. Note that selecting
a waveform does not change the PW parameter,
which affects the waveshape of the chosen wave-
form.
SUB (OSC1 Sub Oscillator) sets the waveform of
the sub oscillator or turns it off. The sub oscilla-
tor pitch is fixed at one or two octaves below the
oscillator.
PW (OSC1 Pulsewidth) sets the oscillator wavesh-
ape. The mid position (64) gives the default wave-
shape. Unlike on most synths, all four waveforms,
selected by WAV, have variable waveshapes.
SPD (OSC1 PWM Speed) sets the speed of the os-
cillator’s PWM LFO, which can be used to modulate
the waveshape back and forth around the set PW
parameter.
PWM
(OSC1 PWM Depth) sets the amount of the
oscillator’s Pulsewidth Modulation around the set
PW parameter. Use this to add subtle or drastic
motion to the sound.
NOISE (page 2)
S&H
(Sample & Hold) sets the tuning of the noise
spectrum.
COL (Color) sets a filter that changes the frequen-
cy content of the noise oscillator. Negative values
render lowpass-filtered noise. For example, a setting
of -64 is red (-6dB/oct) and -32 is pink (-3dB/oct)
noise. Positive values render highpass-filtered noise.
A setting of zero disables the filter, making the out-
put white noise.
FAD (Noise Fade) sets the fade-in or fade-out of the
noise. The mid position (0) gives a constant noise
output. Positive values give a fade-out, negative
values give a fade-in. The graphics will illustrate
the slope of the fade, across the spectrum, as you
tweak the encoder.
LEV (Noise Level) sets the level of noise.
