Nothing sounds like the 909 hihats. Only 6-bit, but somehow very clear, smooth and snappy. Jomox sounds very harsh in comparison, nowhere near as good and hardly useful IMHO. The sampling frequency on the 909 seems to be around 60khz at the stock tuning setting judging from spectral analysis.
Anyway, I just recorded the hihats with a lot of knob settings straight into a good converter at 192khz (downsampled to 96k because there wasn't much useful information in the high ultrasonic region). First from the mix outputs, then from the single outs. Enjoy:
