At rehearsals it would be useful to have a button dedicated to increasing the level of the output block, and another for decreasing it, so that the overall level of a patch could be adjusted to fit the mix of the band. Is there a way of assigning a modifier so that the level would start at the current level and increase or decrease, say, 0.5dB with each tap? The scene-level-and-save utility is good for fine tuning, but sometimes the overall patch volume starts off much higher or lower than others, and changing that first with your foot (not a mouse) as the band starts would be a quick way to get in the ballpark. Then, save the patch at the new setting and use scene-level-and-save for the nuances, if necessary.
