Key bindings not working

Support
1

Hi

I have some trouble with key bindings. It doesn’t seem to work.

I created a keybinding with spacebar to toggle play/pause. But nothing happens.

I have the system bip when I press the key.

I’ve tried this command in the terminal : sudo log stream --debug --predicate ‘subsystem==“com.supermegaultragroovy.capo.CapoRemoteControl”’

and I get this:

thanks for your help

Pierre-Marie,

Three things:

  1. Can you check if any of the other default keystrokes work? For example, the M key should place a marker, and the K key should place a chord.
  2. If you create your own keystroke for another key (like W or Q), does that one work okay?
  3. When you ran the terminal command, did you start the log before you launched Capo, or was Capo already running?

Thanks!

1 - K, M doesn’t work. But Ctrl+Cmd+L works or Cmd+[

2 - No, it doesn’t work (I also noticed that keyboard bindings are not saved if I quit the app)

3 - can’t remember, but I can retest both way

with the app already open:

Ok. I tried to reinstall the app from the MAS and it seems to work fine now.

Sorry

There it is! Capo encountered some kind of problem when it was trying to translate your old keyboard and MIDI mappings to the new system.

There’s an easy fix for this, but first I’d like some help from you so that I can prevent this from happening to others in the future. Please do the following:

1. Capture your legacy playback commands

Run this command in the Terminal. It will use pbcopy to place the information on your clipboard.

defaults read com.supermegaultragroovy.capo3.mac CapoPlaybackCommands | pbcopy

2. Send me the legacy playback commands

In your reply to this thread, just hit paste (command-V) and it will dump a bunch of text.

If you want to be extra safe, maybe paste them into a text file somewhere in case something goes wrong. We’re about to delete them…

3. Delete the legacy playback commands

Make sure Capo isn’t running anymore. Then, at the terminal run this command:

defaults delete com.supermegaultragroovy.capo3.mac CapoPlaybackCommands

4. Re-launch Capo and test

If the problem is actually resolved (it should be!), then your spacebar and other keyboard commands should work correctly.

Let me know how it goes.

No problem at all!

I’m glad to know that’s another solution that seems to work. I don’t know exactly why it worked… But if I had to guess, you might have had a slightly older version of Capo installed, and re-installing got you a version where I already applied one fix for this issue.

Now you can go off and learn songs again with keyboard shortcuts working. Yay! :slight_smile:
