Appendix: MIDI Note Mapping

All Poly presets use General MIDI drum map assignments, compatible with Cubase Drum Maps, Native Instruments Battery/Kontakt, and any GM-compliant kit.

Note names use the Cubase default convention: Middle C (MIDI 60) = C3, MIDI 0 = C-2.

Design Notes

Non-Western instruments are mapped to the closest GM equivalent by role rather than by timbral similarity. The choices prioritize rhythmic function over acoustic accuracy:

• Kanjira (39 / Hand Clap) – 54 (Tambourine) would be slightly more accurate for a frame drum, but Hand Clap works as a snappy ghost layer in the Carnatic Tala preset.
• Pandeiro (70 / Maracas) – 54 (Tambourine) is arguably closer, but Maracas gives the right shaker-shimmer role for the Bossa Nova preset.
• Ghatam (42 / Closed Hi-Hat) – no GM equivalent exists for a clay pot. Closed Hi-Hat fills the rhythmic shimmer role well in the Carnatic Tala preset.
• Afrobeat bell (56 / Cowbell) – Ride Bell (53) is an alternative for timeline bells, but Cowbell is valid and more universally mapped across drum kit plugins.

These mappings ensure that any GM-compatible drum instrument produces a usable result without custom drum map configuration.
