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.
