Separate filters for each channel with programmable cut-off frequency would have been awesome though. You could do so much synth with that as well as eliminate the aliasing from the samples!
Incidentally I've lately been experimenting with compressing my samples by upsampling, and restoring them with a Lanczos interpolation. Works quite well.
