7.2.8.1 LFsyn = LFO Syncronization < 000/128 >
If LFO sync is on <128>, the LFO phase restarts with every note trigger. For this
reason, most LFO waveforms have a positive or negative version stored (For example
+sine and -sine). If the LFO waveform restarts with the trigger it makes a huge
difference if the signal sweeps negatively or positively first.
If off, the LFO runs free and you can, for instance, slowly modulate the cutoff frequency
and create up- and down waves on the filter independently from the notes played.
7.2.8.2 LFVCA = LFO VCA Amount
< 000-127 >
The LFO can modulate the loudness of the sample. This is also called tremolo if the LFO
speed is in a certain range. Please note that only the sample gets modulated, not the
analog VCA envelope. Therefore you can only hear the effect if the sample is in the
signal chain and the envelope is open (key is held). If this parameter is at maximum
<127>, the LFO waveform closes and opens the sample volume at 100%. With <000>
there is no modulation and the sample has full volume. Any value in between will only
partly open and close the sample volume.
7.2.8.3 LFcut = LFO Cutoff Amount < 000-127 >
LFO cutoff amount can modulate the filter cutoff with the LFO. You can only hear the
effect if the filter activated in the filter routing is >= 1. If the resonance is high, you
can create a sweeping tone with the filter
7.2.8.4 Acc = Accent
< 000-127 >
Accent determines how hard the instrument is played when an ACC is set in the
sequencer. The maximum accent level also depends on the volume of the instrument.
The volume defines the absolute maximum level that is played if accent is set to
<127>, whereas lower accents adjust the dynamics in the range between the two
values (no ACC = volume/2) and (ACC = volume/2 + accent).
