Gale,
I’m really surprised that you regard 30b as too difficult beginners
I’m certainly no geek in this regard - I’ve never used a real mixing board so to a large extent you could regard me as somewant of a novice with this stuff. When I was testing 30b for Steve I certainly found it probably the easiest to comprehend compared with all the previous versions. The controls seemed simple (well as simple as they can be for this effect) and clear.
Furthermore I’m struggling to understand why you say you need more preset curves. The choice between just the two shapes is one of the thingshat makes 30b so delightfully straightforward - but still capable of yielding powerful results.
As an example I tested using a 5-second generated sound wave so I could see the effects of the controls on the fade curve shapes - It took me only a little experimentation to get a curve of the same shape as the existing Cross-Fades that you are fond of.
Peter.
