Editing Controlling the simulator with MIDI

The simulator in the [[Using the Sandbox FV-1 Editor|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 ==

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 ==

# 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 ==

{| class="wikitable"
! 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.
