Hi again Anoop!
Yes, that's it exactly!
Sorry, I hope I wasn't too patronising earlier, I never know how much the person I'm talking to already knows... in this case, quite a lot by the sounds of things!
On an interesting and related note, you know how a wheel spinning really fast in one direction looks a bit like it's spinning slowly in the other direction You can get the same thing with sounds too, so (if I've got this right) if you've got a sample rate of 10kHz and one of the harmonics is 12kHz, it will sound like it's 8kHz instead, the sample rate *minus* two instead of plus two. This is the reason why sampler inputs have a built-in low pass filter at half the sample rate.
Anyway, yes, samplers of that era will *not* sound as pristine as a CD quality sample. If it's any consolation, I spent many years making music in trackers, starting out with 8363Hz samples, at 8-bit resolution as well. It didn't sound great, but just the ability to use a sampler was amazing enough that I for one didn't really care. :) Now it's a whole crunchy aesthetic in its own right!
All the best,
Zoë.
