Creating EFM1 Random Sound Variations
The Randomize facility (shown at the lower right of the interface) generates new sounds. It does this by randomly altering a number of key EFM1 parameter values.
This feature is ideal for creating subtle variations of a particular sound, or for creating totally new sounds when you’re feeling uninspired (or need a hand to get started with FM synthesis).
Click the Randomize button. You can click as often as you like, but remember to save your settings as you go, if you happen across a sound that you want to keep.
Drag in the numeric field to determine the amount of randomization (variance from the original sound).
You should use values below 10% if you only want to randomly “tweak” the current sound.
Use higher values if you want to radically change the sound with each click.
