Firmware 4.1 Bug - Master Tempo On/Off again.

The old 'Master Tempo On/Off' bug is present in the latest firmware.

You can easily make two perfectly locked in time tracks go out of time, causing a trainwreck, by turning the master tempo functions on/off a few times. I appreciate that this isn't something most people do during normal operation (i was doing a few tests for the 'drift' thread) and wondered if MT was still causing it.

However, it is a bug and shouldn't be happening, it was supposed to be fixed by an earlier firmware release. i can recreate 100% of the time - can someone else see if they can do it?

This is normal as the audio is bypassing the MT DSPs when it's not in use; engaging the MT re-routes the audio and incurs a minor delay in doing so.  Simply put, if you engage the MT mid-mix, expect that there will be a delay.

ok pulse, make sense. i can't imagine most people would MT of/off 10 times whist mixing 2 tracks together anyway. just wanted to make sure the old bug hadn't made an appearance.

No - from what I understand there was a latency that they addressed and it has been markedly improved.

Hi Pulse,

I don't think what you are saying is entirely true - you can turn MT on/off on things like serato with it not affecting the tempo - it shouldn't be that hard here either. From a quick look at the cdj2000 service manual it looks like the DSPs are always in the audio path, so there's no "re-routing" to bypass them. This looks purely like a software issue (I don't see any reason why the hardware wouldn't support glitchless audio manipulation) - can you ask them to take another look as I'm sure they could improve this. Thanks.

phil , you say : i can't imagine most people would MT of/off 10 times whist mixing 2 tracks together anyway..

I must agree , so I don't see a problem with this "Bug"  :)

@Will > Regardless, it's not a bug, it's a condition of operation and it won't adversely affect performance if used correctly.

How is it not a bug? I didn't notice this as a significant problem on the CDJ1000 and previous comments suggest it would be fixed on the CDJ2000. Is it really too much to ask to have the engineers take another look?
