Under pressure for a possible solution; as an upcoming gig in about 15 hours from now.
The t4 master volume knob, ( far left , round black knob) is not functioning at all.
Regardless of what setting. the volume is maxed out. The only way to control volume is with the mixer in the tyros.
I suspect there is a simple solution to why the vol knob is detached from its normal function.
Any suggestions appreciated.
