s-2 is a polyphonic synthesizer designed to work with the Roland AIRA Compact S-1. ENGINE Each voice runs two parallel engine slots that mix together. Pick a sound flavor per slot, including: • Classic analog — saw, square, sub, noise, pulse-width • Wavetable • FM • Speech • Chord • Plucked string FILTER AND FX Classic mode runs a vintage-style ladder filter into a simple Delay → Chorus → Reverb chain. Modern mode swaps in a multi-mode SVF (LP / BP / HP) followed by a 3-slot Advanced FX rack with Bitcrusher, Drive, Flanger, Phaser, Auto-Filter, Tape Delay, Plate Reverb and Chorus. MODULATION Two free-routing LFOs (sine / triangle / saw / square / random / noise, with optional clock-sync), a dedicated filter envelope with two destination slots, and a unified mod matrix dialog that visualizes every routing in one place. Click any knob in Learn mode to assign — no digging through menus. FORMATS • Standalone for iOS • Audio Unit (AU) for Logic Pro and other AU hosts • AUv3 plugin for iPad / iPhone in AUM, GarageBand, Cubasis and more - s-2 is an independent third-party application.
