drumkv1

a really solid FOSS drum kit sampler for Linux. great set to features to manipulate individual drum samples in the kit as well as a nice set of effects to apply to the entire kit. comes as both standalone version as well as lv2 plugin version which works great with Qtractor (or any other Linux DAW). It's not as advanced as in you can't send individual drum samples in a kit from a single plugin instance to different audio output/buses afaik, but you can of course adjust vol and other parameters independently for each sample in drum kit from within the plugin. But otherwise it's a very useful tool for creating drum groove using one shot drum samples via a MIDI editor/piano roll such as in Qtractor etc.
