A3000 filters are reeal good, some hot trance or deep house or ambient subtleties arise in a soundsample depending which filter type is applied (providing you R willing to break all the rules and/or learn all the rules, and mess with the parameters).
And realtime controlling of a sample's filter parameters can be applied via
a Nordlead2 knob (or some other true synthesizer with at least midi out and a filter sweep knob).
Hey! cool tip - If you go into the sampler and assign a function to the A3k's "assignable" button that resets any outside changes to the your initial sample filter settings, this can be very convenient.
warning tip-any filter sweep sent on say midi channel 2 will affect all samples in the program that have had a filter put on them and that are setup to respond to midi channell two.
When you set a sample to respond to a midi channel, you can push the knob underneath the number, it flashes, you hit a note, and whatever channel your synth or sequencer is transmitting on automatically replaces the default of midichannel one. Same for choosing the original, high, and low note mapping of the sample on the A3000.
