Subject changed to reflect that I now have solutions I can share with you.
I recently posted an aggressive wah style lead preset here. I was really trying to make a dent in recreating Derek Sherinian’s Monster Lead originally done on a Korg Trinity and featured in many works under his name, Planet X, and Dream Theater. There are plenty of examples on Youtube (e.g. Derek Sherinian - Master Class (Transition Riff No Third) - YouTube), but I’m failing to do a good job here. If I had a block diagram of the preset, I’d be able to make a good stab, but my poor ears aren’t really telling me enough. Can anyone in the peanut gallery help and old codger out?
