Program Up/Down Switch

An optional control for the Hexpander MIDI Interface, this switch allows you to scroll up and down through your MIDI converter's sounds.

It's the same as what some converters call an S1/S2 switch.

You may also want to add to your installation:

PE-0111-00 QuickSwitch for MIDI/both/guitar
PE-0181-00 Hexpander MIDI Volume Pot

If you want all three of these options with your Hexpander, it's better value to order the Hexpander MIDI interface Kit.
