new settings for delay and reverb

[fox]

I personally would suggest to the developers to make more settings in the event marker for the 'blend' option, specifically I want to be able to input when the transition should begin, or how long before the marker that the transition should start to occur.

you can already do all of that with markers

also, reverb and delay are probably not going to get anything more than an on/off state. if you want custom delay, use note volumes and space them out how you want. reverb might get some more presets but thats about it.
