Can you 'flip' the OH track in EZD? Have no idea, and I only assume that its drummer's perspective, too.
Yes, I send all the EZD tracks to separate tracks in Reaper. Not only for any FX (I typically have more reverb on snare and OH), but also for mix adjusting, tweaking the mix as its gets close to the finish - why would I want to open up a secondary mixer, when its all in front of me with the regular view?
Well...I do the same with my SD tracks...send them to my DAW app....but, I first "set" my kit basics in SD.
I don't just send the SD tracks "raw", as-is to the DAW, and then tweak them there...mainly because tweaking them in SD, the basic stuff, is much easier.
It's like...SD is where I fine tune the kit setup...like you might do when you're setting up the mics and your pres and all that shit, and tuning the drums and selecting the snare and the cymbals...etc...etc.
Like I said...in SD, I go to the mixer...hit one button..and the entire kit is flipped from L to R, or R to L.
Much easier doing that there. I also use the SD mixer and instrument panel to tweak the tones, the level, the pitch...etc.
I would think you could do some of that in EZD (I assume you are talking about EZD2...?)...but just from what saw in EZD1, which I have, and the demos of EZD2...neither is as robust with its kit control and tweaking options as SD is capable of.
You should consider upgrading. I can guarantee you will never go back to EZD.
I mean...EZD 1 and 2 are OK for just grabbing some drum tracks...but if you want to be able to treat the drum tracks as if YOU had actually recorded them....then SD is the better tool.
