Ah, sorry, not being deliberately vague I thought everyone was reading and keeping up to date on five pages of my vacillation and deliberations... :headbang:
I went with Native Instruments Abbey Road Vintage Drummer.
It took me quite a while to get my head round how it was working but I mostly got there in the end. There are a few frustrations though.
The drop down to select the different kits doesn't load properly in Reaper (haven't tried it standalone yet) so you have to step through each version to get somewhere and as there's two versions of each kit this is a long time thumb twiddling whilst waiting for the kits to load.
But the main frustration at the end of the evening was that, after the kit has loaded and all the sounds are sounding, well, nice. Making any changes to the mixer control takes 5 or so seconds to effect. So if you want to mute a channel, or raise a fader, or solo something, you click a button, wait a bit, then the action happens. It's just about ok if you're making a single change (say soloing the kick) but if you want make a few changes at the same time it's a ball-ache.
Likewise playing with any of the built in effects, there's some nice SSL emulations in there but trying to A-B something effectively is a mare.
Will try again at the weekend and see if there's anything I'm missing - wouldn't do any harm to do some general housekeeping on my computer as well - but none of my other VSTIs behave like this.
The drums sound good though! ;)
Ignore the post count, I have no idea what I'm doing...
