POT2.5 is a polyphonic octave generator that stacks sub octaves, a fifth and upper octaves under and over everything you play, chords included. Swell it in, filter it, detune it, and spread it across the stereo field.
Now available for MacOS & Windows
What's Inside
Play chords, double stops or single lines. Every note is transposed, so the octaves follow your full voicing instead of glitching on intervals.
-2 and -1 octave, a fifth up, +1 and +2 octaves, each on its own slider next to your dry signal. Organ stacks, 12-string shimmer or a bass under your guitar.
Every voice has its own pan knob. Spread the octaves wide, keep the sub dead centre, and turn one note into a full stereo section.
Fade the octaves in on every note for bowed, pad-like volume swells, from a quick bloom to a slow three-second rise.
Low-pass, band-pass or high-pass with continuous Q, plus an envelope that sweeps the cutoff up or down with your playing.
Transpose everything up to ±12 semitones, dry included, and detune the upper octaves for a thick, chorused shimmer.
MIDI Learn every control in one click. Voice levels, pans, attack, filter, detune and bypass, all on your controller.
Step through presets and banks, load a preset with the effect on or off, or save your current sound, straight from your MIDI footswitch.
Ten banks of ten slots. Save your stacks and recall any of them instantly with MIDI Program Change 0–99.
POT2.5 takes the polyphonic octave pedal idea and gives every voice its own channel: two sub octaves, a fifth and two upper octaves, each with a level slider and a pan knob, blended with your dry signal.
The upper bank shapes the whole stack. Attack swells it in, the filter tames or sharpens it, and Detune thickens the top end. Dry FX decides how much of that processing your dry signal shares.
Three footswitches step through presets and bypass, just like the pedal on your board.
Every voice gets a fader and a pan knob, so the stack is yours to balance. Pull the -2 Octaves up for a bass line under your chords, ease in the +5th for organ drawbar colour, or push the uppers out wide for 12-string sparkle.
Then shape the lot. Pick LP, BP or HP, dial Q for bite, and let Env sweep the cutoff with your playing. Pitch moves everything up to an octave either way, no capo needed.
The octaves always get the full treatment. Dry FX decides how much of it your dry signal shares: Off keeps it untouched, A adds the attack swell, A+F runs it through the filter too, and All puts every control on the whole sound.
On stage, three footswitches handle the rest. Preset Down and Preset Up step through your sounds, Bypass drops it out, and the Active light tells you where you stand.
Control
Put the whole pedal under your feet. In the VST3 version, MIDI Learn any control in one click: voice levels and pans, attack, filter, detune, pitch and bypass. Step through presets and banks from your controller, or call up any of 100 presets directly with Program Change.
It ships with a factory CC map laid out like the hardware it grew from, so a controller already set up for the pedal on your board drives POT2.5 straight away.
