Detune for phonk type music

[Liam]

You open the console ctrl+shift+j
You put setDetune(instrument, detune) and put in the instrument and amount of detune
E.g
setDetune(808 Drum Kit, -2400)

Close. But instead of typing "808 Drum Kit", you need to use the instrument's number. For 808 Drums that's 36:
setDetune(36, -2400)

But I can never remember all the instrument numbers, so I find it easier to just select the instrument I want, and then type "instrument", which stores the instrument number that's currently selected:
setDetune(instrument, -2400)

There's more details on that wiki page.
