Improved Drum Grid Reliability Resolved duplicate input handling that could cause unintended drum triggers. Stability Improvements Internal fixes to improve sequencing consistency and overall reliability. ### 0.2.2 — 2026-04-09 • Expanded KEYS & CHORDS piano roll — now reaches deeper into sub-bass range • New House & Techno randomizers with shared musical key detection • KEYS and CHORDS now generate patterns that work together harmonically • Updated CHAIN lengths: 2, 4, 8, 16 bars • Added 2-bar chain option for faster groove building • Improved MIDI export consistency across octave ranges ### 0.2.1 — 2026-03-28 zpunk now generates standard MIDI files automatically whenever you save a project, making it easier than ever to continue your ideas in your favorite DAW. New Features Automatic MIDI export on project save Exports the full chain arrangement Separate MIDI files created for: Drums (Traditional style layout) Keys Chords Chops Drum velocity levels are preserved Note lengths and chord timing are exported correctly MIDI files saved inside the app and accessible through the Files app Why this matters: You can now sketch music ideas quickly in zpunk, then continue refining them in: Ableton Logic FL Studio Any MIDI-compatible DAW Start anywhere — finish anywhere. ### 0.2.0 — 2026-03-22 New House Mode for chord generation A major musical upgrade to the progression engine. Long press the KEYS or CHORDS tabs to activate House Mode. Chords now follow house-inspired progressions with richer voicings — including 7ths, 9ths, and suspended chords — along with groove-focused phrasing. Instead of static block chords, patterns now feature offbeat stabs, syncopation, and evolving variation across bars. Improved multi-bar generation All randomizers now respect the full CHAIN length. This means: • Chords, keys, and drums generate across multiple bars • Patterns evolve over time instead of repeating a single bar • Melodies and chords are linked together, sharing the same key and musical direction The result feels much closer to building a real track — not just looping patterns. ### 0.1.8 — 2026-03-18 No release notes. ## Apps similar to zpunk | App | Rating | Price | Category | | --- | --- | --- | --- | | [Rhythm Pads – Music Board](https://appshunter.io/ios/app/rhythm-pads-music-board/id1628795764) | — | Free | Music | | [Rivet 04 - Comb](https://appshunter.io/ios/app/rivet-04-comb/id6758967505) | — | Free | Music | | [DAF-100](https://appshunter.io/ios/app/daf-100/id6759817075) | 4.8 (6) | Free | Music | | [Pianond: Piano Keyboard](https://appshunter.io/ios/app/pianond-piano-keyboard/id6778135307) | — | Free | Music | | [LE01 \| Bass 808 Synth + AUv3](https://appshunter.io/ios/app/le01-bass-808-synth-plus-auv3/id1502480224) | 4.8 (1,129) | Free | Music | | [Rivet 02 - Room](https://appshunter.io/ios/app/rivet-02-room/id6758566292) | — | Free | Music | ## More apps by Shanna Ragavan - [Pocket Punk](https://appshunter.io/ios/app/pocket-punk/id1611714154) - [kmusic](https://appshunter.io/ios/app/kmusic/id6639588222) All apps by Shanna Ragavan: https://appshunter.io/developer/1611714486 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
