I haven't used it as an effect but I have recorded the bass with it and then added the effects. Mine is for use live for complex samples and sounds - I have an MPX that can play samples, but it is litterally just a sample playback tool, and when I wanted to play the same sound but longer or shorter or with a different velocity (ie, keyboard stuff), i went for the MPC, especially with the multisampling where you can have the same sample at different velocities, so on the MPX you can play back the same sample at a lower volume when you hit the pad softer, but on the MPC you can play a different softer hit sample and it makes quite a difference. And the MPC can play back sequences on a pad too
