I'm not certain you can do that in EZD. There's no key switching involved in that program, that I know of anyways. I was thinking, cymbal crash, and then another midi note to follow (on the piano roll view) immediately after the crash, a few small ticks afterwards, with the velocity turned all the way down, for the choke effect. I've done that a few times myself (in EZD), when I actually thought to do it (cause for some reason, I couldn't find a cymbal choke sound - might have been using an EX pack that just didn't have one - I think the vintage rock kit doesn't have a choked cymbal sample, at least I didn't find it), as it was needed at that particular point in time, and got pretty much the same result. That's the thing...sometimes there's so many ways to skin the cat, you can't keep up with all of the options.mojobone wrote:Most drum synths have note groups, as well, so that a closed hat will cut off any ringing open hat sound; you could assign a silent note as a keyswitch to cut off any or all cymbals this way, though I don't know if you can do this in EZDrummer.
Unless you (speaking for myself) sit back, and really think about it.
