Original release notes
Thanks Everyone! FREE UPGRADE: • NEW: MICROTONALITY Explore new sonic territory with 150+ curated microtonal scales, including North Indian scales, Hexanies, and scales by Irv Wilson, Marcus Hobbs, and more. • Import Scala .scl tuning files and bring your own custom scales into the app. • NEW: WORLD SCALES Explore 60+ international scales with selectable root keys. Choose from Arabic, Egyptian, Eastern, and other world scales, then pick the base key that fits your song. • NEW: WESTERN KEY + SCALE SUPPORT Choose a key like C minor, Bb, F minor, and more. Select from Major, Minor, Blues, Pentatonic, and other familiar scales. Keep your arps, sequences, and external MIDI locked to a Western scale, world scale, or go fully microtonal. • NEW: PRESETS SAVE THEIR KEY AND SCALE Want Preset #17 to always load in D minor? Now it will. Save presets with the correct key and scale for songs, live sets, and performance patches. • NEW: AUv3 STATE SAVING FOR TUNING AND SCALE Your tuning and scale settings are now saved properly inside AUv3 sessions. • NEW: TUNE LOCK Tune Lock button starts unlocked, so presets can load with their saved tuning. Tap the lock icon to keep the same tuning while changing presets. • NEW: PROGRAM CHANGE MIDI MAPPING You can now use a custom MIDI CC to change presets. Go to the About Page [i], tap “MIDI Mapping,” then “Add/Edit Mapping.” Choose “Program Change,” then enter the CC you want to use. PLUS: More improvements under the hood. This is a big leap forward Thanks for supporting the app, Analog Matthew
