The Live Monitor shows all three.
Move a control to see its MIDI message, value and device in the Live Monitor.
The message is checked against your mappings, including any device and value limits you set.
An enabled mapping runs its AppleScript when the trigger matches.
Put Mac controls on the hardware you already use.
Assign keystrokes and AppleScript to your controls, then choose how each mapping responds.
Put a keyboard command on a pad or button. Select 'Shortcut…' and record a keystroke, including modifiers such as Command or Shift, then assign your MIDI control. The keystroke goes to the app in front. For media keys or system actions such as Mission Control, choose a supplied Script Library entry instead of recording them.
Control a level from a fader's position. Turn on 'Send value' to make the incoming position available to your script as midi_value. Your AppleScript can convert that value into Mac output volume or Music's playback volume. During a fast sweep, newer values replace those still waiting to run, so the mapping follows the latest position without working through every intermediate value.
Start with one of 109 supplied scripts for tasks such as changing volume, controlling Music or sending a keystroke. Choose an entry and read its requirements before assigning a control. Save your own scripts to the Library for reuse, and check Used by to see which mappings use a script.
Assign a control by moving it. Select 'MIDI Learn', then press a button or move a fader. MIDItoAppleScript captures the trigger and selects the device that sent it. Check whether you captured the press or release before saving. They can send different messages and trigger different actions.
Use several connected controllers together and choose which one each mapping listens to. 'MIDI Learn' selects the device you used, so an identical note from another controller will not trigger that mapping. Choose 'Any device' when you want the same trigger to work across controllers. The message and value still have to match the mapping.
Give the same controller different jobs with separate sets of mappings. Keep music controls in one profile and presentation controls in another, then select the set you need from the sidebar or MIDItoAppleScript's menu bar icon. Duplicate a profile to use an existing setup as the starting point for another job.
Use an endless knob to raise or lower a value, such as your Mac's output volume. These relative encoders send direction rather than a fixed position. Choose 'Relative' mode and the format your controller sends, then set 'Step size' for each click. Turn on 'Faster turning' for larger changes when you turn quickly, and 'Send value' to pass the resulting position to your script.
Make a control act only within part of its travel. Set a range to ignore values outside it, then turn on 'Fire once' to run the script on entering that range. For example, a pitch strip can skip to the next track when flicked to the top. It must leave the range before another entry can fire again.
