Oscillator as waveshaper
(tip by urs)
For more gnarly and different oscillator waves, try the following: Set an oscillator’s Modify mode
to
Multiply
it’s 0.00 value “freezes” the oscillator. This is your waveshaper. Now connect another
oscillator to the phase modulation input with the mode set to
PM coarse
or
Lin 1kHz.
Turn up
the phase modulation and PD levels, then play and watch the ‘scope. Experiment with various
waveforms for the waveshaper as well as the driving oscillator.
LFO Tricks
More lively LFO
The easiest way to inject a bit of ‘life’ into an LFO is to select
Rnd
as the rate and/or amplitude
modulator, with the amount(s) set to about 0.20 max. Recursive modulation strikes again!
Global envelope
The organ ‘percussion’ effect only happens on newly played notes after any other notes have all
been released. Although Bazille doesn’t have such ‘global envelopes’, you can use the
Delay
of
a very slow LFO in single mode to emulate one. The Delay is your ramp, which you can re-
shape using a mapping generator if you like. Set the LFO’s
Phase
to 50 or above.
Alternatives to LFOs
If two LFOs are not enough, remember that you can always use oscillators, looped ramps or
envelopes instead. Each of these alternatives has its own advantages / specialities.
Filter Tricks
Self-oscillation
You can play notes just using filters by setting the Resonance and Key Follow both to maximum,
and Cutoff fairly low e.g. +12.00. Experiment with all 6 filter types. Caution: self-resonating filters
can get very loud, so it’s best to turn the volume down first!
Especially the lower notes are slow to self-resonate, and a short impulse is often necessary to
kickstart the resonance. Patch an unused envelope into one of the filter inputs, and pull all the
sliders down to minimum except the Decay. Adjust the Attack, Decay and filter Gain for various
flute sounds.
More cutoff modulation
Both main filters allow
four
freely definable cutoff modulations, but only if you use one filter at a
time. Try this: Change filter 2 cutoff mode to
Spread
, and connect whatever you like to the cutoff
modulation sockets in the
currently unused
main filter. If filter 2 is your unused one, note that
the extra control works in the opposite direction. Confused? Just try it, and maybe read all about
the
Filter Ping
(tip by justin3am)
Feed any impulse-type signal (pulse LFO, gate, short envelope) into a filter with fairly low gain
and the resonance set to just below self-oscillation – usually somewhere around 50.00. This can
result in interesting tuned percussion sounds, especially if you also modulate the cutoff with an
audio signal. Note: the ‘ping’ decay also depends on input gain and cutoff.
Filtering control signals
Lowpass filters are basically audio-rate lag processors with extras – so there’s nothing stopping
you from using them to process control signals.
