KENTON electronics GS-2 MIDI Guitar Amplifier FootSwitch Controller User Instructions
Introduction At last, an affordable unit which enables you to put your amplifier foot-switches (channel/overdrive/graphic etc.) under MIDI control, enabling to control them from your MIDI pedal board or MIDI seqeuncer. For playing live or in a studio, the GS-2 makes your set-up work for you freeing you to get on with your playing. Setting Up MIDI Connections The GS-2 must be connected to your MIDI set-up.
1, Channel and System Settings To be in Channel edit mode, the yellow `CHannel` LED must be lit. If the `PATch` LED is lit, press the `PATCH/CHAN` key. The display will now show the current MIDI channel number 1 to 16. The system settings consist of; MIDI channel Whether foot-switch control AMP A is a normal or momentary type control Whether foot-switch control AMP B is a normal or momentary type control Editing the MIDI channel; To edit the MIDI receive channel number, use the `+` and `-` keys.
2, Patch Edit Mode Selecting patches; To be in patch edit mode, the green `PATch` LED must be lit. If the `CH` LED is lit, press the `PATCH/CHAN` key. The display will now show the current patch number 1 to 128. As the GS-2 only has a two digit display, a special method is employed to display numbers larger than 99.
3, Controller Assignment Mode This is an `advanced` programming mode is for those who wish to control each of the amplifier foot-switches individually (as opposed to all at once within a patch) from their sequencer or other MIDI device. Each device can be activated by its own MIDI controller (or several MIDI controllers at once). This mode is not likely to be used live by a guitarist, but used within a studio or home set-up being controlled by a computer sequencer.
