I've never heard of trying to use e-cymbals. My thought would be, why bother? They sound terrible acoustically and that would get recorded. More over, there should be a click running to record in this manner, if that isn't enough for the bass player to go on as you track, I don't know what is. Lastly, I think they often lay down just drums first to a click when operating with separate cymbal and drum tracks. Everyone else dubs.Yep, a totally legit technique, though I had thought (and this seems like it should be the case if it is not already) that the idea is you record with electronic cymbals and then replace those. That way you have some simulacrum of the auditory response you're expecting, which helps not only you, but also anyone else who may be tracking along with you, most commonly bass. When you go back and replace the cymbals there is a small 'thwack' sound that will be buried by the real cymbal sound, and may just add a tad of definition to the cymbal attack.
