"Welcome Prism" (sorry, no link) from Technictix contains two samples that I've heard elsewhere:
Front Mission 3 - Base Invasion (the high whistling synth starting at 0:07) &
Mega Man Zero 2 - Ice Brain (the sample that kicks in right away, which I'm pretty sure I've heard in another VG track or two as well)
Anyone know where these are from?
Also, how about
those synth toms that SuperSweep has used a lot (among other artists)? It has a very distinct sound to it.
