Controlling the simulator with MIDI
The simulator in the Sandbox FV-1 Editor can be played from a MIDI controller plugged into your computer. The pots and the effect switch respond to control changes, so you can sweep a parameter with a real fader while a program runs.
The Sandbox pedal itself has no MIDI input. This drives the simulator only.
Before you start[edit | edit source]
Web MIDI needs Chrome, Edge or Firefox. Safari does not implement it, so the MIDI Control section will not connect there. Everything else in the simulator still works — see Using the FV-1 simulator.
Connecting a controller[edit | edit source]
- Open the TEST DRIVE tab and find the MIDI Control section.
- Press Enable MIDI and allow the browser's prompt.
- Choose an Input. All inputs listens to every device attached.
- Choose a Channel, or leave it on Omni to accept all sixteen.
The status line beside the button shows the last message that was accepted. If it never changes while you move a control, the message is not reaching the page at all — check the input and channel before you check anything else.
Your input and channel are remembered between sessions, and a controller that is unplugged and plugged back in is picked up again on its own.
What the controls do[edit | edit source]
| Control change | Moves |
|---|---|
| CC50 | POT0 |
| CC51 | POT1 |
| CC52 | POT2 |
| CC102 | The effect switch: 0–63 bypasses, 64–127 engages |
MIDI moves the same controls the sliders do, at the full 128 steps a control change carries, so a program cannot tell the difference between a fader and a mouse.
