If I remember correctly, there is a video on here called Rare Slipknot Samples. I also used a video that had just the vocal, extra percussion and sample tracks for Psychosocial. The piano parts I just simply played and recorded on the sampler itself. Again, if I remember correctly hope this helps.
The keyboard OP is playing is being used as the controller for the sampler (Korg Electribe ES-1 Mark.I) The ES-1 uses a memory card as its sound bank, so to do this you simply load slipknot samples into card, pop her into the Electribe, then use a MIDI controller (in our case, a Keyboard) to trigger the samples at will <3
(MIDI is like a programming language for music, it just means it’s a Keyboard [or Controller] with the ability to transmit data back and forth with other instruments)
@@scotty2033 no problem!! nowadays you can do this much more easily (though I prefer the fun in using a pile of old equipment) by loading Craig & Sid's samples directly into a Korg "Volca Sample", sort of a portable version of the Electribe that OP's got here
