What? You must be kidding! 200ms is a HUGE FUCKING amount of time, when
making music. 100 ms is even way too much. When syncing my HD recording
to my synth and sampler, the latency MUST be < 20ms or else it sounds ilke
shit.
Just get a MIDI sequencer from the Internet somewhere and try to shuffle
the drums or melody
around by blocks of 50 ms. I assure you you will be surprised.

Apart from that, it is imposible to select single notes from a recording,
be it analogue or
digital. The first person to be able to deconstruct digital music like that
would earn a
nobel prize, for that would mean that a critical function of the human
brain had been
emulated by computers, and that would be a breakthrough for real AI.
