Appendix A: SYNTH TRACK PARAMETERS
In this appendix, the parameters of the synth tracks are explained.
OSC 1 (page 1)
TUN (OSC1 Coarse Tune) sets the pitch of the oscillator 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) decides whether the oscillator pitch
should follow the notes you play. When off, the pitch is constant,
which can come in handy for some drum or effect sounds.
LEV (OSC1 Level) controls the level of the oscillator. Normal
level is 100. The sound can get dirtier at higher levels; lower lev-
els 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 Saw-
tooth, 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 waveform.
SUB (OSC1 Sub Oscillator) sets the oscillator's Sub Oscillator
waveform, or turns it off. The Sub oscillator pitch is fixed at one
or two octaves below the oscillator.
PW (OSC1 Pulsewidth) sets the oscillator waveshape. The mid
position (64) gives the default waveshape. Unlike on most
synths, all four waveforms, selected by WAV, have variable
waveshapes.
SPD (OSC1 PWM Speed) sets the speed of the oscillator's PWM
LFO, which can be used to modulate the waveshape back and
forth around the set PW parameter.
PWM (OSC1 PWM Depth) controls 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.
FAD (Noise Fade) controls the fade-in or fade-out of the noise.
The mid position (0) gives a constant noise output. Positive val-
ues give a fade-out, negative values give a fade-in.
LEV (Noise Level) sets the level of the noise.
OSCILLATOR 1
The OSC1 pages control the first oscillator, its suboscillator, plus the noise generator.
