What's a supersaw?
You can't know what a supersaw is if you don't know the Roland JP-8000 synth.

This is a really basic and plain supersaw.
7 saws with different initial phase offset, detune and panning.

Tips:
- Reset all the phases to 0° to have a plucked supersaw, ready to be used with a low cutoff freq
- Get inspired with the JP-8000 sample in its wikipedia page: https://en.wikipedia.org/wiki/Roland_JP-8000
