Omnivore Software has released WOPR – a polyphonic, stereo virtual analog synthesizer for iPad that features unique evolving modulation, driven by vintage 1970s cellular automata.
WOPR is a powerful virtual analog synthesizer, but what sets it apart is its modulation grid: you paint a pattern of cells into a grid, set the tempo, hit ‘run’ and let the cellular automata evolve your pattern. You can link areas of the grid to any of the synth’s parameters and your patches come to life, rhythmically pulsating as the patterns shift with each beat. You can constrain parameters to ranges for tight control over rhythmic modulation, or set them free to dynamically breed new patches.
Core synth engine:
- 2 pannable oscillators with sine, saw, square and triangle waves. Each oscillator has an incredible range: 32′ to 1′, with +/- 500 cent detune (a perfect fourth either way). There’s also a white noise generator.
- 3 ADSR envelopes, 2 assignable between osc 1 & 2 and the third dedicated to the noise source.
- 2 resonant 24Db/octave low pass filters, assignable to osc 1 & 2 or to the left and right stereo channels.
- 2 delays, a free-running delay with fine control over low intervals, and a tempo-synced delay running from 32nds to two whole beats. Delays are independent, or can be assigned to feed each other in any sequence.
- 2 octave, full-width ribbon keyboard: play piano like a guitar, bending individual notes or entire chords.
- 6 voice polyphony.
- Modulation matrix: use this to link controls to the Game of Life, or simply use it to define a custom control panel for easy performance.
Note: WOPR is made for iPad 2 or later only. There’s no mention of MIDI support at this time.
WOPR is available now in the App Store.
