Wave instructions can be compared to midi instructions. Both are instructions that tell something what to do. However, WAV instructions can be used only with PG Music RealTracks audio. Thus the idea of WAV instructions is proprietary to PG Music while midi instructions are a universal standard.

Midi instructions is data that directs a midi instrument patch what to play. The sound you hear is generated in real time by a midi instrument patch.

PG Music RealTracks are prerecorded audio files. The Band-in-a-Box program generates WAV instructions that is data that tells Band-in-a-Box, RealBand or the Band-in-a-Box Plugin how to select, use and manage RealTrack audio. A very rough example of a Band-in-a-Box generated WAV instruction is: the audio in "ABC" RealTrack is a "Gmaj7" chord that starts here in the audio file and ends here in the audio file.

Whichever PG Music program you're using, Band-in-a-Box, RealBand or the Plugin, uses Band-in-a-Box generated WAV instructions to select, use or manage RealTrack audio.

Rendering a RealTrack tells whichever program to follow the WAV instructions to create a new audio file.

Until recently RealBand or the Band-in-a-Box Plugin had to wait for the main Band-in-a-Box program to render a RealTrack before the RealTrack could be managed by either program.

Now both RealBand and the Band-in-a-Box Plugin can read and understand WAV instructions so the wait time for Band-in-a-Box to render a RealTrack is eliminated. Both RealBand and the Band-in-a-Box Plugin can now directly access the original RealTrack audio files stored on an external or internal drive so any changes you make to a chord sheet doesn't take as long to implement.

One way to gain a better appreciation for WAV instructions is to investigate how UserTracks are created.
