Just a heads-up that Slapper has had a big update.
The most significant change is the addition of a mono reverb tail on each delay tap. This follows pan position and you also have a variable verb amount parameter on each tap.
It's a pretty significant change, and I think it'll change the way you use both delays and reverbs.
We've also added support for the 7.0.2 and 7.1.2 formats, with a 3D panning interface, similar to Spanner 3.
There's a new mini interface mode - which allows you to leave all your Slappers onscreen as a heads-up to what's happening - only popping one open to edit it.
And a bunch of other features, fixes, tweaks and improvements.
