The hardest test is to record a MIDI groove for kick, snare and hihat.
I then used my Alesis D4 drum module that don't cause audible jitter
when using it with the C64 and Atari ST.
I did record the audio output of the Alesis D4 by Linux, but each
instrument one after the other, each instrument two times.
The result:
Playing one recording of the two recordings for each instrument and the
groove is broken. It doesn't matter if it's a beautiful McCoy Tyner or a
stupid Madonna like groove.
Playing two recordings, but just of one instrument the phasing is not a
constant phasing, but fluctuating. An early reflection similar effect
usually isn't the result, but in the worst cases even this is possible.
