Adjustable offset helps, but the greater the latency the more disconnected you feel from the beat. 200 ms would be absolutely unplayable. To put that into perspective, 200 ms is an eighth note when the music plays at 150 bpm. So every time your fingers move you have to wait an eighth note to see and hear the result.
