Hi

. . . . Are all instruments royalty free?  . . .

If you are:

1. composing an original piece of work - if you are using someone else's composition it may be subject to Copyright and/or Royalty fees
    
2. using the Instruments to either write the notes (MIDI Editor) or playing those instruments using the computer keyboard or a MIDI keyboard

Then there are no royalty fees, or commercial licences needed to use.

However, if you use Soundpool loops in your composition, and are publishing for commercial gain, or on a site that supports adverts and makes a financial gain, eg Youtube, then you need Commercial licences for every Soundpool that contains a loop you use.

The full licencing terms for Soundpools are here.
