Nope, and unfortunately, never will in realtime (in the samplers you can do this as an offline process). This was the hardware tradeoff E-mu made in giving you 128 voices.

SLoop offsets the loop points. The loop length stays the same.
Interestingly, with the Gain4x cord, you can actually push the loop points *into the next sample* making for VERY weird and somtimes cool sounds.

I just said that no current E-mu hardware synth with 128 voices will be able to play samples reversed in realtime.

Pitch-shifting sample playback is complicated. E-mu uses a very high quality pitch shifting technique that invloves the use of many input samples to generate a single output sample.

The short story is that to perform these conversions, lots of memory bandwidth is needed. The more voices you play, the more memory bandwidth you need. At 128 voices, the available memory simply wasn't fast enough to keep up. The patented solution to that problem unfortunately precluded reversing samples in realtime.

E-mu doesn't hype the quality of their pitch shifting very much these days, but they're probably the best in the business.
