Multi Instruments

Creation

Since we are going to work with multi-instruments all the time, let’s break it down!

A multi-instrument can contain single instruments, event instruments, programmer instruments, command instruments, silence instruments and other multi instruments.

You can create a multi-instrument in 2 different ways: right click the audio track and select Add Multi-instrument or drag and drop multiple audio files from your file explorer.

If you click your newly created multi-instruments, you will find something like this on your bottom dock.

You can see the settings are pretty similar to Wwise.

Master

This is where you can control the volume, pitch and starting offset of your instrument.

If you right click all the parameters, you can always add randomizer like in Wwise.

Synchronous? Asynchronous?

It is important to understand the difference in between Async and Sync while implementing in FMOD.

In a synchronous instrument, it will start playing your sound from where your play cursor is. You can trim the unwanted section of your file or add silence at the end of your file.

If you stretch the tail of your synchronous file, it will be looking like this.

However if you enable Asynchronous by clicking the Async button, it will ALWAYS play from the beginning of your instrument no matter where your play cursor is. And if you drag the tail of your instrument, it will stretch visually on your timeline but the length of the sound is not going to be changed.

You can do something like this by using Async and Sequential

Moreover, you can’t cut inside your instrument like you can in the synchronous instrument.

Playlist

In Shuffle and Random, you can decide the play percentage of each sound. By default, all assets inside an instrument have an equal probability of being selected to play. Play percentage allows you to change this by setting specific entries to have a higher or lower chance of appearing.
