After spending MUCH TIME manually adjusting beat grids on A LOT of songs I was dismayed to find EP played back every one of them at a varying tempo as a result!! Disable “Key Lock” and it’s even more noticeable, as the pitch gets changed in portion the tempo.
I was not happy to (finally) get my tracks on to my brand new Prime 4 only to discover that none of my “warped” beat grids I had spent years adjusting in Serato survived the migration over to Engine Prime. I play classic Rock/Pop & Funk; there is almost no such thing as any material from that genre having a steady tempo. Many Effects sound stupid if the grids are off the actual beats, especially things like Echo. And forget Roll, it won’t even work.
It seems that Engine Prime is locking on the BPM value and playback is then determined by how many milliseconds is in between each Beat Marker to maintain that value, regardless if the Markers have been adjusted…If the Beat Marks are closer together the song is played faster, further apart and it gets played slower.
The Beat Marks in EP are “elastic” as to being able to adjust each and every one of them, (as opposed to Serato/RekordBox-you can only adjust/anchor the first beat) but then playback is faster or slower as EP tries to “push” the tack along to where there’s the same amount of time distance between each one.
Try this with Stevie Wonder’s Superstition. Just played straight you can tell the tempo changes in the song. I wish I could watch the expression on your faces as you try to adjust the Beat Markers as the song goes berserk, especially as you get closer to the end.
I know this isn’t the first time this has come up; it’s just that when it has it’s been buried in a paragraph. The purpose of this post is to put the issue as a topic, front and center. Many, many others have hit on it over the years in this Community. SonnySeven lists it as the main issue for abandoning EP and selling all his Denon gear, (see “Engine Prime 1.2 is here but it’s time to say goodbye”). THAT WAS ALMOST 1-1/2 AGO!! Denon acknowledges that this is a “known issue” but it’s still not fixed. I just downloaded 1.3.3 hoping that the “BPM Issue” is fixed. Well, it ain’t.
I hope Denon comes out with a new update that fixes this SOON. Until then, I suggest you “Reset” all of your manual adjustments to any track.
