Which Decks for Beatmatching?

Humm, wonder what is the root cause of that. How big a difference in bpm (%-wise) do you mix apart?

The bigger the pitch shift the more work the player has to do. And it can come to the point where it becomes pretty ugly.

Another thing, since you are mentioning synths and pads, is that these instruments can produce pretty “unnatural” waveforms. But I am just venting a few thoughts here, nothing from experience.

I have two SC2900s and haven’t noticed such a thing. Can you give me two tracks that always do that on your 1200s and 1 or 2 tracks that definitely don’t do it and I’ll play them on my SC2900s and see what happens. Perhaps I can hook up a recorder and tape the sound coming out of the main or record out of the mixer and send it back to you? Would that be helpful?

I think the processing power in the 2900s is way beyond what was ever in the 1200s and the sound cards inside them are awesome, as are the ones in my X1600 mixer (Traktor Scratch certified).

Good to meet another long time Denon afficionado :). You don’t want to switch to Pioneer, LOL. If you are used to Denon quality at Denon prices, your are gonna feel so … mmm … what is the politically correct word … just fill in the blank … when you switch to the “big” Pioneer tickets at almost twice the price.

I don’t think the sound card processes the key pitch, this (my understanding) is done by the actual processor of the mediaplayer. Usually ASICs (application specific Integrated Circuits) in older equipment. In newer equipment you see more “general” processors running Linux adaptations for example. My old Numark D2 Director for example was running a Numark linux version.

I think that only the processed audio (i.e. after pitch) is offered as input for the sound card and the sound card does the same with any signal (pitched or non-pitched) which is translate digital pulses to analogue waveforms. And garbage in means garbage out. Hence my guess that it is not the sound card at fault. Every 16-bit 44K1 sound card should do just fine, really.

Ok. Will give it a try. 2% does not sound as enough of a pitch correction to cause problems on my SC2900s. Will look at it this weekend and let you know.
