Yamaha .sty → MIDI file (.mid) → Medeli GrandSuite (import) → .AKX Use Style Works (discontinued but functional) or MixMaster (free, by Michael Bedesem) to open the .sty file and export only the style sections (Intro A/B, Main A/B/C/D, Fill, Ending) as a single multi-track MIDI file.
1. Objective To determine a viable workflow for converting Yamaha auto-accompaniment styles (typically from PSR/SX/Tyros series) into the proprietary .AKX style format used by the Medeli AKX10, ensuring correct playback of drum maps, chord recognition, and voice mapping. 2. Key Technical Challenges | Challenge | Yamaha (.sty) | Medeli AKX10 (.AKX) | | :--- | :--- | :--- | | Format | CASM (Chord Assist Module) + MIDI | Proprietary (similar to MIDI + internal mapping table) | | Drum Map | XG/GM (usually standard GM drums) | Medeli GM2 (similar but some key offsets) | | Voice/Sound | XG, MegaVoice, S.Art, Live! | GM2, Medeli native voices (SF2-based) | | Chord recognition | CASM rules embedded | Internal chord engine (no direct import) | | File extension | .sty, .prs, .bcs, .sst, .pst | .AKX | Critical note : Medeli does not provide an official style converter for Yamaha → AKX10. Conversion requires indirect methods. 3. Recommended Conversion Workflow Because no direct converter exists, the process is: how to convert yamaha styles to medeli akx10
No major changes needed for standard GM drums. Only special Yamaha kits (e.g., “RealDrums”) may require manual remapping. Yamaha
