Multi-Sample Player sample pack requirements

Folder layout:
- One instrument per normal folder.
- Keep the folder unzipped when copying to phone storage or microSD.
- Put WAV files directly inside the instrument folder. Nested subfolders are ignored by the app loader.

WAV format:
- WAV PCM only.
- 44.1 kHz or 48 kHz sample rate.
- 16-bit or 24-bit integer PCM.
- Mono or stereo.
- Avoid MP3, FLAC, AIFF, Apple CAF, floating-point WAV, or compressed WAV.

Naming:
- Every WAV file name must contain a note name and octave, such as C3, CS3, C#3, Db3, F4, or Bb4.
- Add velocity as V1 through V127 when possible. Example: My_Keys_C3_V96.wav.
- If velocity is missing, the app treats the file as V127.
- For drum kits, use 16 chromatic notes from C3 through DS4 for the 16 pads.

Performance targets:
- For this Moto G Stylus build, 16 to 64 playable WAV files per folder is ideal.
- Short one-shots and keys should usually be 0.2 to 3 seconds each.
- Long ambience or release tails can work, but large folders will be thinned by Moto Smart loading.
- The app copies playable audio into RAM; microSD is a library source, not the real-time streaming source.

AI generation prompt:
Create an unzipped Multi-Sample Player instrument folder. Render clean PCM WAV files at 44.1 kHz, 16-bit stereo. Name every file with InstrumentName_NoteOctave_VVelocity.wav using note names like C3, CS3, D3, DS3. Keep the folder flat with no nested folders. For melodic instruments, render 16 to 32 roots across the useful range and one or two velocity layers. For 16-pad drum kits, render exactly one sound per chromatic note from C3 through DS4. Trim silence, keep peaks below -1 dBFS, avoid clipping, and make each sample start promptly.
