I switched (back) to apTrigga. Much cheaper, much more stable (no bugs), and much more accurate in all my experiences. In my opinion it makes Drumagog look like a chump, all dressed up with nowhere to go. Whose idea was it to have a little video screen of a foot hitting the kick drum on every shot? This is VST though, so you'll need the VST-RTAS wrapper for this. I love it for sample reinforcement, as it allows you to click through & preview samples very quickly. Much better than Drumagog in this regard, and you don't have to make GOG files out of your samples. Whether you make your own samples, download them from a forum, are given them from another producer, or purchased, they're all going to be in .WAV or .AIFF, maybe SDII format. Do you really want to convert all of them into GOG files? I sure as hell don't. Besides being over $200 cheaper, more stable, and (IMO) a better interface, they give you another plugin for free called spikeGen, which creates MIDI triggers from audio. Doing that allows you to edit the drum performance as MIDI and trigger a 3rd-party drum module such as BFD, DFH, DM5, etc. You may prefer that route for replacement. apTrigga rules.
Kenny's method rules too, and is the most accurate. When using a plugin like Drumagog or apTrigga, before the final mixdown, you'll want to print those tracks, so you can check them. I use apTrigga while building the mix, to preview my library of sampes in real-time in the mix (with no latency!) and once all is said and done, I go through and use Kenny's method to place the samples in the session. Kenny's method makes this much faster.
