Munagi: Cloud is a generative visualization based on control by touch and motion from accelerometer. Shape algorithms borrow from Fibonacci patterns, l-systems, and wave functions. Any images or video created with this program are entirely yours. Feel free to send them to me. Precursor to this program is Munagi (win/mac/linux/android.) More to come.
Fang is a synth app based on motion modulated control through accelerometer information. Each parameter can be linked to different directions of motion. Contains presets, wav recording, a stepped arpeggiator with diatonic scale locking, a multi-pattern sequencer, wave shaping oscillators, resonant filter with envelope and pitch following, and an effects rig (including formant (vowel) filter, pitched delay, reverb, down-sample, bit reduction.) Capable of strange sonic textures, complex evolving arpeggios, or classic sequenced synth sounds.
Notes are generated with a sequencer and keyboard. The sequencer works by moving a step at the rate specified. There are four patterns that can be played and edited independently.
The keyboard has a set of notes that can be played or buttons which hold notes. Held notes can be cut off by sequencer notes and play notes of the same pitch.
The arpeggiator receives notes from the sequencer and keyboard. Its rate is controlled by both synced time and ms that are added together. It has variable steps, step transpose and gate. The steps and timing can be reset periodically with the optional arp reset. There is optional diatonic scale locking as well, allowing you to select a root note and scale from major, dorian, phyrygian, lydian, mixolydian, minor, and locrian.
The synth’s sounds are generated with five voices, each with two oscillators that modulate between triangle and saw. Modulation is effected by an envelope. There is a pitch envelope that effects both oscillators. The oscillators are capable of fm (osc B modifying osc A.) Both oscillators can have their signals sent to the filter or directly to the amp envelope. A white noise signal can also be added to the filter or directly to the amp envelope.
The filter is a 4 pole resonant band-pass whose frequency can follow the pitch. It is also effected by its own ADSR envelope. The filtered and unfiltered signal is sent to a per voice down sample and per voice delay under synth menu. All voices are sent to an effect rig with a formant (vowel) filter, pitched delay, reverb, and bit reduction. Presets and wav files are stored at /device root/fang/.
