Connecting with an external MIDI device
On the GX-100, you can use MIDI to perform the following operations.
- For details on MIDI, refer to “GX-100 Parameter Guide” (BOSS website).
Operations from the GX-100
Operation | Explanation |
---|---|
Transmit program change messages | When you select a memory on the GX-100, the program change message specified by MEMORY MIDI is also transmitted. The external MIDI device that receives this program change message will switch to the corresponding settings. |
Transmit control change messages | When you operate the [C1]–[C2] switches or the footswitches or expression pedals connected to the CTL 3, 4/EXP 2 jack, this is output as a control change message. These messages can control parameters on an external MIDI device. |
