Is there a way to achieve both phaser and octaver in Boss ME-70? They appear to be under the same pedal, is there any trick for it?
The manual seems to indicate that, in memory mode, you can assign an effect to arbitrary patch (pedal) position using write mode. This suggests to me that you can assign any effect to a different patch pedal than the one you'd normally be forced to use in manual mode.
See Boss ME-70 User Manual (page 10)
