What MODELAR does
- Four oscillators drone all the time, each with twelve waves and eight routings from mix and ring to chain FM.
- The sixteen white keys form an XY pad: touch one to glide the cursor there, hold several to sit between them.
- Eleven black keys draw gestures such as circle, eight, spiral, tremolo, random walk and bounce, latched with SEL.
- K1 to K4 always fade the four oscillators in, and MASTER sets the main volume.
- A stereo chain adds filter, drive, fold, ring, crush, tremolo, chorus, delay and reverb.
- The sequencer holds eight patterns with a KAOS lane and four oscillator lanes, each its own length for polymeters.
Its modes
- KAOS PAD
- Play the white keys as a four by four grid of points that move the cursor.
- bars
- See four bars and set the volume, wave and tone of each oscillator.
- FX
- Set the filter, VCA tremolo, drive, fold, ring, chorus, delay, reverb, crush and FX level.
- ENV
- Pick a generative environment and set drift, drift speed, mutation and density.
- LFO
- Shape two LFOs and set the clock rate, source, swing and jitter.
- EDIT
- Assign two destinations each for X and Y with slew, attack, release, range and curve.
- GLO
- Press a key to give it its own point or gesture, intensity, oscillators and X/Y destinations.
- ARP
- Arpeggiate the held points with mode, rate, gate, glide, swing, latch and spread.
- SEQ
- Build patterns across the KAOS lane and four oscillator lanes with length, rate, swing and direction.
- SYSTEM
- Set MIDI options, pad colours, lights and check the version and audio load.
