Improved audio on iOS: better audio startup behavior and metronome playback on iPhone/iPad. More natural piano feel: notes don’t cut off as abruptly when lifting your finger (smoother “release”). Reduced audio clipping/saturation: lower gain on iOS (especially for the piano) for a cleaner sound. Sample playback improvements: better pitch handling for sampled instruments (piano/guitar). Help & onboarding refinements: improved in‑app help overlays and metronome help layout on mobile. ## Apps similar to MIDI Piano & Guitar Chords | App | Rating | Price | Category | | --- | --- | --- | --- | | [Hum2MIDI](https://appshunter.io/ios/app/hum2midi/id6786317080) | — | Free | Music | | [BeatForge Studio](https://appshunter.io/ios/app/beatforge-studio/id6785533942) | — | Free | Music | | [GTB Guitar Chords](https://appshunter.io/ios/app/gtb-guitar-chords/id6764719857) | — | Free | Music | | [DoomLoop](https://appshunter.io/ios/app/doomloop/id6766733624) | — | Free | Music | | [Gibber - Learn Guitar Chords](https://appshunter.io/ios/app/gibber-learn-guitar-chords/id6780884722) | — | Free | Music | | [JingleJam Music](https://appshunter.io/ios/app/jinglejam-music/id6777500340) | — | Free | Music | ## More apps by Antonio Ortega Gonzalez - [Marcilen](https://appshunter.io/ios/app/marcilen/id6741707805) All apps by Antonio Ortega Gonzalez: https://appshunter.io/developer/1772528526 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
