Re: [xl7] drum kits

2002-04-30 by Aaron Eppolito

Actually, it's almost the opposite from that.  The instruments on any of
the Proteus 2000 and later (including XL-7, PK-6, etc) are not simply
multisamples.  They are pretty much full-on E4 presets, complete with
key ranges, multiple layers, velocity crossfading, amplifier envelopes
(this is where the "factory" envelopes come from).  They are not simple
"this keys range plays this sample" multisamples (and especially not one
big long sample with offsets!).  This is also why the keymaps we provide
are complicated (and even these are simplified!) because the instruments
are so powerful.

see just how to create a P2K instrument.
