The integrated low frequency oscillator (LFO) can effect up to five destination parameters. The LFO speed will synchronise
automatically to an externally applied MIDI clock.

Bitpattern
Up to seven destination parameters can be effected by the modulation
wheel: [ADRS Release], [OSC Volume], [Filter Resonance], [Filter Cutoff
Analog, [PWM 1] and [PWM 2] can be assigned in form of an bitpattern
to any possible combination. The desired combination can be taken
from the “Bitpattern“ table chart.

Meaning
Filter Cutoff

0-127
Adjusts the digital filter cutoff frequency.
Filter Resonance

0-127
Amplifies the digital filter resonance area.

Bitshifter. The waveform after the digital filter can be shifted upwards
by a level set here. As soon the upper limit is reached the truncated part
will be inserted at the lower limit again. Thereby experimental sounding
tones can be generated here once more.

LP = low pass filter
BP = band pass filter
HP = high pass filter

0-127
After the digital filter and DA conversion, an additional analog low-pass
filter follows. The analog filter cutoff frequency is adjusted here.
Note : this parameter isn‘t useful for dynamic control because disturb-
ing noises can occur while playing notes and changing this parameter
at the same time.
Filter Link ADSR
29 or 80
On: 64-127
Off: 0-63
The amplifier envelope can control the digital filter cutoff frequency if
linked. [On] will activate the link.
