the qv-l is a quad low-frequency oscillator with a variety of waveforms, flexible modulation options, clock sync and presets.
waveforms included as of firmware 0.9.0:
sine, triangle, saw up, saw down, shark left and right, and square waves, all with variable shape controls (pulse-width for the square wave).
sample & hold with selectable source (cv in, any other lfo, etc).
three morphing waves: sine to tri, saw to tri, saw to square
stair-step up, down and up-down
a sine / saw / square sequence-able waveform.
a variable-pulse width square wave sequence-able waveform.
a three output lorenz attractor chaotic waveform.
a perlin-noise style random waveform
a logistic map chaotic waveform generator.
lfo rates can be set using a variety of modes. there are two logarithmic response modes (wide and slow) to cover traditional ranges. there is a hz mode for specifying the rate from 1hz to 246hz. there are also 3 tempo-based modes: 16th, beat and bar.
the qv-l's tempo can be set internally, or via a 16th note tempo clock to a gate input. the qv-l can also be connected to a vector sequencer for sync and bi-directional midi communication.
the qv-l also includes two simple, linear egs for modulation duties. the egs currently have two modes: ar: attack/release, and asr: attack/sustain/release.
the qv-l supports extensive modulation via 8 modulation busses, with selectable sources, destinations and amounts. sources include 4 cv inputs, all 4 lfos, and either of two internal envelope generators.
in order to accommodate multi-output algorithms such as the lorenz attractor, and for general versatility, each of the 4 cv outputs can be custom mapped. output processing also includes a selection of handy operations (invert, rectify, etc) and both sale and
offset controls.
lfos can be reset (and egs triggered) from either of the two front-panel gate inputs, or from the triga or trig b buttons.
most edit pages have animated waveform displays.
the main edit page offers 6 customizable parameters for each performance control.
all settings can be saved via onboard presets in flash memory. up to 40 presets can be saved.
