Just My Imagination?
 

I just started using Keyrite, and so far, I think it's great! The changes the software makes seem pretty natural. However, do I notice just the slightest bit of slow-down in the processed track after it has been key changed, or is it just my imagination?

Your imagination...
 

Well, I'll forward this on to our programmer to see what he thinks. We have never had this reported before, so I don't think it is actually happening. We use a very sophisticated algorithm, and it might have sample rate correction as part of the processing.

I'll try to get back to you on this with a second post after I get an answer. :w

Does not shift sample rate
 

Our programmer who wrote Keyrite has reported "Keyrite should NOT change sample rate at all. As far as I know it is exact." He wrote the code from scratch based on a proven algorithm. He is the best Digital Signal Processing (DSP) programmer I have had available to me in 31 years, so I am confident this is a correct answer.
