| Problem | Likely Cause | Ultralight Solution | | :--- | :--- | :--- | | | Resource pack missing required instrument | Use mididump to see missing patches; reassign in Polyphone | | High CPU usage (>20%) | Polyphony too high | Limit polyphony: fluidsynth --polyphony=32 | | MIDI playback too fast/slow | Sample rate mismatch | Force rate: -r 22050 on player and in your audio chain | | Resource pack won't load | Corrupted SoundFont | Use sf2_analyze tool to validate; resave from Polyphone | Part 7: Building the Ultimate Ultralight Rig Let’s put everything together. To build the definitive ultralight MIDI player resource pack work station, follow this recipe:
fluidsynth --load-preload --sample-rate=22050 ultralight midi player resource pack work
echo "Resource pack work complete."
