Audio Dropouts on Rekordbox 4.0.5 with Pioneer DDJ-RX

Macbook Pro (13-inch Early 2011)

2.3GHz Intel Core i5

16GB 1333MHz DDR3 RAM

1TB HDD with about 600GB free space

 

Having some serious issues with my new setup,

I recently bought the DDJ-RX in order to utilise the new Rekordbox software and for some reason, with no other programs running apart from the system programmes. I'm getting Audio Dropouts and glitches. It's subtle enough in some cases to not notice but it can get so bad that the 4/4 beat jumps and stutters. These audio artifacts tend to last about 1/2 a second at a time and can be frequent or non frequent as it wants.

I used Activity Monitor to see how my CPU was doing and its at anywhere between 80-150% on Rekordbox. I also noticed that during these periods of stuttering the "Audio Dropout Meter" is pumping. Not to the max, but its lively.

 

Anyone have any tips/answers?

 

Thanks

Oliver King

If you open the Activity Monitor, do you have any other applications running with considerable resource use?

That's the operating system. If you sort by the CPU % or Memory (on the Memory tab) you can see the highest-users at the top.

Yeah that's what i meant. the only thing below Rekordbox that's above 10% is Kernal_task. nothing else

Did you try sliding the buffer size to the max (2016 samples) ?

I'll try that in a second and get back to you, although i just switched between browse mode and 2-Deck Horizontal Waveform mode for a few minutes at a time and the CPU usage is considerably lower when its in browse mode. Could it be something to do with the Waveforms?

The next question is how it behaves if you change the drawing performance from HIGH to MEDIUM (found in the preferences).

I'll try that as well, do I need to quit Rekordbox and reopen it when i change these settings at all?

I've just created a ticket for you, you should see an email - our rekordbox team will get it and probably ask you a few more questions.

Hi,

Same problems. I tried, I believe all that is possible.

Pioneer ddj-sx2 / Rekordbox 4.05 / Mac Book Pro i7, 16gb Ram, 1To SSD, 500gb free.

The cpu get crazy with more or less noise and glitches on sound, without reason.  Can you imagine the situation when you mix in club or big party ?! It comes from Rekordbox for sure, I tested the SX2 with Traktor and Serato and it works perfectly. Unfortunately I prefer Rekordbox ! (However, a organisation of the tracks like Traktor would be welcome...for me.)

Thanks if you have an idea / solution, or I will be obliged to leave Rekordbox !

@Oliver > Have you tried using another USB cable?

The engineers would also like you to provide a screenshot of the activity monitor, both the CPU and MEMORY tabs, please.

How does the dropout meter work inside of Rekordbox? Mine is at 50% when I play on performance mode? Do I need to worry? How do you lower it?
