Adding @lookback to ampslice-based JIT onset detection?

Do you happen to know how @lookback works in terms of the point it picks offhand?

I do, I devised it with @groma It looks at the lowest value within that window - so if you have a decaying cymbal followed by a hit, it will go to the lowest point of the decay. does that make sense?
