Hi
Have you tried your controller with any of the c/c banks that I have posted?
If you have your controllers mapped to the same numbers as the emus midi controller page through from A to L then your midi controller should now have some effect on the filter envelope in these presets.
You may find that if the frequency cutoff is set to max on your controller, the filter envelope settings may not have any noticable effect .
Once you have achieved tweakable control of my bank you can then be sure that the controller is working and correctly mapped.
From here you can start to write your own presets.
If you then experience lack of envelope control try looking at how I set my cords.
To be honest it took me a lot of trial and error befor I had any success with envelopes.
You could always delete my samples, replace with your own and modify the settings to suit.
I generally start with a previously saved template (a sample-less preset) with the cords set as needed
Lfo filter Wobbles ( HPF LPF & BPF) Midi clock for filter wobbles and Amp Gates, Mono and Polysynths, whatever.
Try building some presets and then save a version without samples in a folder called TEMPLATES
Don,t forget envelope 3! I often use this for pitch (nice for those alpha Juno type Hoover synths)
Hope this helps
