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. It is not affiliated with, sponsored by, or endorsed by Roland Corporation.

ToneSpace helps you test your room before you record, teach, stream, sing, podcast, or join an important call. Run a short guided room check and get practical scores for noise, echo, voice clarity, and recording level. ToneSpace listens through your microphone only during the test, estimates how ready the room is, and turns the result into clear fixes you can try immediately. Use ToneSpace to: - Check room tone before a podcast, voiceover, vocal take, class, sermon, meeting, or livestream - Measure estimated noise, echo, clarity, and level from a real microphone capture - Choose scoring modes for podcast, voiceover, meeting, vocal, church or hall, online class, and general recording - Follow a guided silence and voice test so you know exactly when to stay quiet and when to speak - Save room profiles and compare how a setup changes over time - Track score trends after moving a mic, closing a window, adding a rug, or softening reflections - Listen back to saved voice samples when sample saving is enabled - Share a clean PDF report with scores, metrics, and suggested fixes - Use dedicated live tools for room echo, background noise, and real-time level checks - Control local history, saved samples, theme, and privacy settings ToneSpace is built for practical creators and everyday rooms. It is not a certified acoustic lab, and its readings are estimates, but it gives you a fast way to understand whether your room is quiet, controlled, and ready enough for the recording you are about to make. Privacy is central to the experience. ToneSpace works without an account. Sessions, room profiles, reports, and optional samples stay on your device unless you choose to share them. You can turn off saved samples and clear local data from Settings.
