SoundFont Instruments

When you are using the built-in synth, the SoundFont Instruments window lays out every instrument in the bank that is currently loaded, so you can see exactly what you have to play with.

  • Open it from Display → SoundFont Instruments.

What it shows#

  • A scrollable grid of every preset in the active bank, grouped under bank headers, with each instrument's position and name.
  • Each instrument's polyphony cost: a small ×2-style figure on the right of the cell showing how many voices a single note of that preset uses. Stereo and layered instruments use more voices per note, so they reach the voice limit sooner. Hover over a cell for the full wording. (Shown when you have loaded your own SoundFont; the bundled Apple bank does not report it.)
  • The bank header stays pinned as you scroll, and the grid pans sideways if there are many columns.
  • A summary of how many instruments the bank contains.

The window always follows whatever the built-in synth is using: the bundled Apple sound bank by default, or your own SoundFont once you load one. Swap in a different SoundFont and the list updates to match, no refresh needed.

When it is useful#

A few moments where it earns its keep:

  • Checking which instruments a SoundFont actually provides before relying on it.
  • Finding the bank and program of a sound you want to use, for example when choosing a voice in Performance Mode or the Mixer.
  • Spotting which instruments are the expensive ones on a busy file: the higher the voices-per-note figure, the faster they fill the POLY meter.
