TODO {
immediate frontburner {
- support rendering to FLAC
- figure out why it defaults to mp3 regardless of type selection?? (it's because qt does a default suffix)
- add rendering floater
examine commandreader (nextsub w/ default for ,XX?)
wet-only output for delay (be smart about it)
check on filter
revert action
distortion effect
- add ,XX support to global tempo
}
qt update causing some patchboard artifacting on mouse movement
