I have a Yamaha S90 XS synth and when I perform I would like to control the volume of one or more of the zone sliders (in Performance mode) with foot pedals so I can quickly switch from backup to lead.
In case that isn't clear enough, here is an example. Say piano in zone 1 is at volume 115, strings in zone 2 is at volume 50, and the pads in zone 3 and 4 are typically at 0 (this one isn't used much live) and 10 respectively. That would be something like the volumes when I am playing backup. However, the strings (zone 2) become way to live for lead in that, so I would want to back that down to about 20. Also, there may be different times when I want zone 3 or 4 at much higher volumes.
Are there pedal board setups that allow this, and if there is, what would the S90 XS support?
I have two foot pedal control inputs (1/4" size input), a sustain pedal input (in use obviously), and an assignable foot pedal control.
