GarageBand Issues on Mac

Having trouble loading AmpStamp in GarageBand on Mac? We’ve got the fix.

GarageBand, unlike Logic Pro, does not necessarily make audio routing as clear when instantiating new tracks. It makes sense since GarageBand is meant to be more of an introduction to digital recording, providing a quick, easy to use interface to get up and running and making some music. That being said, it can also lead to confusion if you want to dig deeper in knowledge, not in your wallet for Logic Pro, to get more out of GarageBand.

So we need to address an important issue with regards to AmpStamp. AmpStamp is meant for guitar, but can be used on other instruments, and expects mono input. AmpStamp supports stereo output, so in total you can run AmpStamp as either:

• 1-in-1-out, or
• 1-in-2-out

It sounds simple, but that’s not how audio tracks are created by default in GarageBand. In order to get GarageBand to expose plugins that require mono input, follow these steps:

1. Create a new audio track in GarageBand
2. Toggle the input from mono to stereo and back to mono
   • 
   • 
   • 
3. You can now replace the default Compressor plugin with any mono-compatible plugin that you have installed

And that’s it! We tested this with GarageBand version 10.4.6, let us know if this works for you too!
