TRESSE is a polyphonic synthesizer that merges 39 sound engines into one instrument for iPhone and iPad. It runs standalone and as an AUv3 plugin inside AUM, AudioBus, and GarageBand. Twenty-four engines come from Classic MI Plaits: subtractive, FM, wavetable, additive, granular, speech and formant, chords, resonators, and analog-modelled drums. Fifteen more are custom, ported and extended: Karplus-Strong strings, vowel formants, modal and sympathetic-string resonators, a seven-saw supersaw, Hammond-style drawbars, bytebeat, and a multi-waveform wavefolder. TWO LAYERS, ONE VOICE Run two engines at once and crossfade them with the balance knob - each layer has its own filter, envelopes and voice mode. A self-stable SEM-style filter morphs continuously from lowpass to bandpass to highpass to notch and stays stable at full resonance. Two ADSR envelopes per layer shape amplitude and filter independently. Three six-shape LFOs and two step-sequenced MOD lanes route to almost anything - timbre, filters, the layer balance, even the sequencer's own knobs. A master chain adds chorus, tape, ping-pong and lo-fi delays, hall, room, plate and shimmer reverbs, and a wavefolder. GENERATIVE SEQUENCER, POWERED BY VEKTE A generative step sequencer drives the synth with seven algorithms - wave interference, Euclidean, random walk, logistic map, cellular automata, Kaprekar and Fibonacci. Shape the pattern with DENSE, probability, swing or humanize, tie and strum over a full scale and chord system. The arpeggiator can play the main sequence itself - with or without its intervals - or walk your held notes in seven modes. Two synth-macro knobs put any synth parameter on the sequencer page. Presets save, load and rename instantly - and share as compact text keys or QR codes anyone on TRESSE can load. FORMAT AND COMPATIBILITY TRESSE is an iOS standalone app and an AUv3 instrument. Load it in any AUv3 host, including AUM, AudioBus, and GarageBand. Its state saves with your host project. It responds to MIDI note input from any connected keyboard or controller, with MIDI learn on every knob. FREE, ADVANCED, PRO FREE plays all factory presets and offers one editable oscillator layer using EastCoast or RingsInh, the Euclidean algorithm, up to 16 steps, three divisions, three scales and three chord options. LFO editing, Shimmer, MIDI Learn and split sequencing require an upgrade. Manual MIDI CC assignment remains available. ADV unlocks the 24-engine instrument, two editable layers, split sequencers, 32 steps, LFO 1, every algorithm, the arpeggiator, divisions up to 2 bars, Ping Pong, all scales and chords, Shimmer, MIDI Learn, MOD 1 and preset saving. PRO upgrades ADV with 15 additional Våld engines, 64 steps, LFOs 2 and 3, MOD 2, timing options up to 16 bars, Random Walk direction and oscillator/sequence copy-paste. FULL includes ADV and PRO in one purchase. All are one-time purchases covering the standalone app and AUv3 extension. UPDATING FROM AN EARLIER VERSION Version 1.3.0 changes the FREE editing limits. Features previously editable for free, including LFO 1, the second oscillator layer, Shimmer and MIDI Learn, now require ADV or FULL. FREE sequences are editable up to 16 steps. Existing preset and host-project settings are retained: locked features continue to play, but editing them requires the relevant pack. Already available also on desktop as VST3 and AU, for macOS and Windows.
