If frequency was absolutely spot on 1KHz that would have been exactly 24 samples
for one cycle.
That should have been ok, provided that the Akai can loop a sample that short ( ),
and it isn't trying to do some kind of crossfade (which under more normal
use would help, usually you'd loop a much longer fragment).
..but just a fraction off 1KHz, or if the sampling frequency isn't
exactly 24KHz then the loop you're making is still 24 samples, but
it won't fit precisely. There'll be a small glitch at the join
...and that will buzz like anything.
If you're sampling 6kHz then that's 4 samples and massive room for error.
Just the slightest error in how the loop joins up will strongly colour the sound,
Whether the waveform doesn't match across the join, or the Akai does anything other
than allow the raw digits to be sent to the DAC.
I suspect that's what you're hearing.
So, try sampling 100Hz.
Try looping several cycles.
hope that helps,
(my experience is with simulating wavetable sounds with digital editing).
