A full track sounds like a good idea.
Watch with the low pass filtering, though. You're apparently running into what I've run into: When the frequency of the filter changes through automation clipping, there tends to be a random popping noise in the lower frequencies. Pull up the Parametric EQ 2 on that instrument and you'll see what I mean. See if you can get rid of it before you proceed with the full version.
Catches you at the beginning, and holds on
Well done loop that shows a lot of potential for inclusion in a larger piece. Keep it up!
Please contact me if you would like to use this in a project. We can discuss the details.
