A pricy but really amazing sampler. It's not just the visual map organisation of your samples, you can also swap samples lightning fast. Even preform really creative and fun functions like set a filter (sound category, length, percussiveness, etc.) and then swap your whole kit for sounds that are sonically closest to the previous ones while obeying the filter settings.
Pattern editing is pretty smooth, you can drag export MIDI or a WAV right out different, you have a lot of groove control (global or per sample track), accentuator. Good routing options, each sample can be routed into 8 different outputs, a single master output, or both! Each track can be sent to one of 2 build in effects (9 reverbs, 6 delays) and they do sound good. However these effect are affecting the master output, same for the distortion module that's built in.
When the sample is loaded into your kit, you can edit where it begins and ends (basically really easy to mace a glitchy kit out of anything real fast), fades out it, collapse it to mono, etc.. You can set how punchy or soft the transient is, hold and decay. There are more features to modify the sounds themselves, some standard (pan, vol, you know).
And yet there's still more I could mention.
Also, the samples it already ships with are really good. It's a very effective sampler that is not only fun to use but it can really speed up your workflow if needed. Definitely a pricy product but I use it very often (bough it when it came out for the introduction price) and I can't think of any major flaws, nor have experienced any issues or bugs ever.
