I don't know why you were flagged because this is quite relevant to the discussion .. it should be noted that this gated processing technique is quite common and not just for bass/drums - its also used in M/S techniques for recording vocals, acoustic instruments, and so on. I hope you'll train your classifier on different targets of the technique - it seems that would be fruitful, in terms of getting a classifier applied in new ways ..
