| Problem | Likely Cause | Fix | |---------|--------------|-----| | | Polyphony limit too low | Increase max voices to 128 in Settings > Engine | | 12-string sounds out of tune | Vintage tuning mode enabled | Disable “Vintage Tuning” (it intentionally detunes octave strings by 3–5 cents) | | MIDI drag-and-drop from Riffer doesn’t work | DAW folder permissions | Save the MIDI file manually to desktop, then import | | High CPU usage | Multi-mic + high sample rate | Use only one mic position; reduce sample rate to 44.1kHz | | No sound in Pro Tools | AAX not installed correctly | Re-run the installer and select “AAX only” |
