I can't think of ANY way that the pitch changes in a digital recording setup, unless you had/have a pitch correction plugin or changed the bpm of the track.

I agree that the encoding while converting to a different format could be a likely source for the error.

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!

Well, with each of my sequencing software, I can record and play back at any sample rate I want, and it never changes the pitch because the software looks into the file and detects the sample rate. In this case the software must have _assumed_ a certain sample rate and played it back at the rate. The software didn't do the conversion properly (which it should have) because its was locked into a certain clock speed.
