Just joined this magnificent forum although I've been reading it for a while. I just want to point you in the direction of a drum plugin I help develop. It is called DrumGizmo and is both open source and free. It aims to emulate the recording of a real drumkit with multichannel output and a full microphone setup. It's also cross-platform and can be downloaded as a VSTi for Windows or lv2 for Linux (no mac yet, sorry). We released 0.9.3 yesterday. Go check it out at http://www.drumgizmo.org If you want to see a short demonstration, check out this tutorial I made yesterday. Find that here: http://www.youtube.com/watch?feature=player_embedded&v=S0hJ74nNJ7E We plan on releasing a bunch of drumkits for the plugin over the next 6 months'. Also, the file format is completely open and based on xml, so I you have the courage, you can create your own kits. An editor actually exists right now, but it is not really ready for the public. It is included in the sources though, so you can use it if you want. It's called DGEdit. Anyways, we really want to spread the word about this plugin, and any feedback will be greatly appreciated. Also, consider joining us on the officla irc channel at Freenode, channel #drumgizmo. Thanks guys!
