Testere Supersaw Synth AUv3

About this app

TESTERE is a 7-oscillator supersaw synth where each voice stacks 7 saws with per-voice control over detune, phase, waveshape (flavor), stereo pan, and a sine wave sub oscillator. Instead of micromanaging each oscillator manually, TESTERE uses distribution curves to control these offsets. You dial in a curve shape and a spread amount, and the synth applies the resulting values across all oscillators smoothly interpolated, musically controllable, and repeatable. This system allows for infinite combinations, from tight analog-like stacks to wide, animated swarms, all with a minimal set of parameters. Each oscillator is a wavetable oscillator with a selection of saw waveforms. You can subtly vary the shape across oscillators or push it further for complex harmonic shifts. All detune, phase, flavor, and panning spreads are curve-driven and musically scaled, making the synth flexible but not overwhelming. A clean sine sub oscillator is included for adding low-end weight, with an adjustable octave (set in settings) and a level control (in the FX panel). Features: - 7-saw stacked oscillators per voice, 8-voice polyphony - Curve-based detune, phase, flavor, and pan spread - Clean sine sub oscillator with octave and level controls - Single global LFO with assignable target - Analog-style ladder filter with rise/fall envelope - ADSR amp envelope per voice - Built-in arpeggiator - Stereo ping-pong delay - AUv3 plugin support AUv3 Compatible Hosts: Works as a plugin in GarageBand, Logic Pro for iPad, AUM, Loopy Pro, Cubasis, BeatMaker 3, and other AUv3-compatible hosts. Whether you want to dial in tight classic stacks or explore chaotic layered textures, TESTERE’s curve system gives you deep control without micromanagement.

This version - Adds master gain control to the settings menu - Adds master gain AU parameter - Improves the Ping Pong Delay stereo spread - Increases the delay time up to 2 seconds - Fixes the delay tempo time sync - Improves the oscillator stereo spread - Makes toggled buttons more obvious
