Iridescence by Dillon Bastan

Iridescence is a MaxForLive delay effect with arpeggiated note trails via a polyphonic real-time pitch shifting and delay system.

You can select how many notes are in an arpeggiated “chord” created off of the audio input.

Additionally, you can create up to 16 different chords that can transition via a Markov Chain (a probabilistic transition from chord to chord). This device can create beautiful harmonies off of a single note!

There are various settings that allow the device to transform from one purpose to another. It is a powerhouse for real-time harmony on a continuous audio source!

NOTE: This is an audio effect and though similar in some ways it is NOT by any means MIDI note arpeggiator!

IRIDESCENCE FEATURES

• Polyphonic real-time pitch shifting and delay mechanism that creates the effect of arppegiated delay trails on an incoming audio signal
• Up to 8 ‘notes’ to create arppegiated sequences off of the original audio pitch.
• Delay time and feedback settings with swing options
• Ability to create up to 16 chords with different note combinations
• A probabilistic system (markov chain) to transition between the different chords, with manual and automatic transition trigger options
• Individual transition probabilties for each chord with randomization options
• Two different real-time pitch shifting algorithms
• Latching mode with different release options
• Pitch feedback options
• Automatic pitch detection and correction mode to change the note transpotions in real-time based ont he detected note and chosen Scale and Tonic
• Different panning options
• Lowpass and Highpass filter options
• Internal LFO with perlin noise and basic shape options for modulating the filter cutoff frequencies
