That is, it does not matter if the string gauge used for that low E string is 38 gauge or 58 gauge - it will vibrate exactly 82.4 cycles per second when tuned properly. And the time for one complete string vibration (cycle) is ~12.136 milliseconds, again irrespective of gauge.

Good software, especially on a HEX PUP (e.g., GK-2/GK3 systems and even the FTP) can "cheat" a little since the string the signal is coming in on is already "a known." So the interpreting firmware/software MIGHT (could) be able to get away with only sampling the first half, or even the first quarter of a cycle (if the engineers really try hard) - and cut down by half or a little more the amount of time it needs to "decide" the MIDI note; thus improving tracking for low notes.

Of course the SW designers may want or need to "over sample" to be sure (e.g., read one full cycle or at least more than half) to be sure, thus trading "fast(er)" for (more) accuracy.

Thanx for that info. I was not aware that the controllers are that good now. I have read as they haven't changed much since the early days. Like I indicated in my old Casio it takes 1 - 2 string vibrations for it to determine what note is being played. Thus thinner strings work the fastest on my controller. I have tested a number of gauge strings over the years and the 8s worked the best. YMMV.
