The sample rate is NOT the issue here.
Toobz is still right that sample rate issues would not create speed problems on playback. You all have to be more careful when you talk about these things: Statements like "it was recorded at 22.05k, and played back at 44.1k" don't make sense because a sample rate is in kHz, which is the unit for "samples PER SECOND". Therefore, a sample rate alone doesn't change pitch because a sample rate of is always referring to an amount of time (in units of seconds).
Therefore, the CLOCK of your sequencing software was not locked it and off!
