Frequently Asked Questions
What message controls volume balance?
Bank Select (Controller number 0, 32) and dedicated Volume messages (BnH 20H llH) are used to adjust the volume balance.
How can I program a reverse delay effect?
The Delay section allows adjustment of Rev Delay Time (49-89), Feedback/HF Damp (0-17), Center Level, and more parameters for shaping the reversed sound.
What are the frequency range controls for the delay sound?
You can use Low Gain (0-30) or High Gain (0-30) to boost or cut specific frequencies in the delayed signal.
Does the device support panning adjustments for effects?
Yes, Control Change messages using Bank Select (Controller number 10) allow adjustment of 'Center' and 'Right' levels, while dedicated Pan control is available for general parts.
