[linux-audio-user] Keyboardist jitter detection?

Hi. I recently started to play a little keyboard. After guitar and traverse flute, the keyboard seemed the logical next step. I guess its totally normal to have a little problem with exactness. I wonder if there is a MIDI tool that could be used to measure my average jitter so that I could test myself and see if I improve? For instance, when playing BWV 846, it should be actually fairly easy measurable since that piece consists of mostly only 16th notes. Does such a program exist? I know the concept isn't that strange, Stanley Jordan told in a master session he was doing something like this with his MIDI-fitted guitar. -- CYa, Mario
