Ok, this was something that a few people have been asking about on different forums. I now know what a morphing filter is, and I've found one in Synthmaster to play with, goes between high and low pass. Just playing with it doesn't immediately make me go 'wow, that's awesome'. It sounds like I expected, high pass at one end, low at the other, neutral in the middle. Can someone give me advice on the kinds of patches to use it on, and how it's used? Maybe link to some tracks with it in? Do you have to modulate it in some way? Just why is it so awesome?
