LFOs
The two LFOs provided on the Modal 008 are extremely flexible providing both envelope and
LFO functions, both with identical parameters.
The LFOs have individually adjustable delay and release controls allowing the fade in and fade
out of modulation to be musically controlled. In single shot mode, this allows the LFOs to be
a true exponential Attack-Release envelope generator with the wave set to square, and an
Attack-Decay envelope generator with the wave set to saw.
The LFOs can reach audio rates and can be mapped to any analogue destination:
1. Depth: This parameter controls the global depth for all LFO modulation for either LFO1
or LFO2.
2. Waveform: This switch allows you to choose one among the four available LFO
waveforms (i.e. sine, sawtooth, square and sample & hold).
3. Rate: This parameter controls the speed of the LFO.
4. Delay: This parameter controls the initial delay of the LFO. The LFO is initially silent, then
it's amplitude increases until it reaches its full amplitude and keeps constant: 'Delay'
regulates the time needed to complete this initial phase.
5. Release: This parameter regulates the time needed for the LFO to decrease it's amplitude
until it becomes silent once it has entered the 'Release' phase.
6. Sngl: This button activates the LFO's 'single mode': when this mode is on, just a single
cycle of the waveform is read every time you press a key, then the LFO stops.
TIP: if using a sawtooth waveform, the LFO turns into a simple 'decay envelope', that can
be extremely useful to modulate many different parameters, like oscillators' pitch (see
'Modulation' section - later in this same chapter).
7. Reset: This button activates the LFO's 'reset mode': when this mode is on, the LFO
retriggers on each new note received.
8. MIDI Sync: This button activates the LFO's 'MIDI sync mode': when this mode is on, the
LFO is synced to the MIDI clock tempo.
