No sound, wrong mic, or text too small
Fix silent playback, pick the right speakers and microphone, and make Presetti's text bigger or smaller.
Nothing plays
Open Settings (the gear icon), pick Audio and check that Speakers is set to the output you're listening on.
If your audio interface is busy, for example because your DAW is using it, and Presetti can't open it, Presetti says so and plays through your system's default output. Speakers plugged in while Presetti is open appear in the list without a restart.
Record uses the wrong microphone
In Settings > Audio, pick the microphone under Mic. The Search tab shows which mic is in use next to the Record button.
Text is too small or too large
Presetti scales with the window, so a larger window shows larger text. To zoom yourself, press Ctrl + or Ctrl −, and Ctrl 0 to reset. Your zoom is remembered.
