## Description

New in 2.0: output meters and a one-tap master compressor, all 41 engines loudness-matched, hardware knob pickup modes, and a layout that fits any screen.

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
