Here are some banks using midi clocksLINK
http://www.emusonacid.co.uk/forum/viewtopic.php?f=9&t=3651This shows how to use controllers to modulate the sound. These banks create rhythmic filter sweeps in time with your tune using midi clock devisors.
There is downloadable bank and also patch data for you to input it manually, which would be a good way to learn your way around the sampler.
For realtime control of the filter just use the following
CHORD NO------------SOURCE-----------------DEST---------------AMOUNT..06 ---------------------MidiA ----------------- FiltFrq-------------- +100
Source could be whatever you like eg Mod wheel (but ensure that the mod wheel is not patched to vibrato by setting the lfo to pitch chord to 000)
To hear the filter change you need to ensure freq is set to the lowest setting in the filter page so that the controller can have any effect apon the filter.
By experimenting with these chords you will begin to understand the ways you can set up controllers.
I will post a "synth type" bank that gives you C/Controller cords for the amp and filter envelopes, filter cutoff, resonance, detune, sub osc level,white noise and chorus depth soon.
