[1.6.0] Sample rate discrepancy between interface & soft

[Stealthii]

EDIT: Original title changed, see posts below

This bug seems to have only occurred today. Now I can't get rid of it. I use a timecode vinyl setup. Basically the pitch display always tells me the wrong value - when playing at quartz locked 0.0%, the display will show +8.8%. It does not affect the speed of play, the only effects are the pitch display and the BPM display. Pitching still works as intended, but the display of said pitch (and BPM) is always wrong.

I hope this is easy to recreate for you guys, I'll find out if there are any special conditions that cause this problem to arise.

hey,

have you switched the routines? from all relative (the right button) and is an yellow expression mark at the vinyl control buttons?

I think this could be something like J-kut and me had a few weeks ago at Cross DJ RC2 and beta7?

@J-kut maybe we are not alone

Dunno,

I was told it´s been fixed since (speed-refresh on reverse and playback-mode switching)

[Stealthii]

Funilly enough, the flexible mode sets the scroll bar for pitch to match the displayed value. If I press the 0% reset button the display returns to 0%. But now the tune is obviously pitched down. Hmm...

I've FOUND IT!

It turns out to be a sample rate discrepancy between the sound interface, and the software. Mixvibes Cross said the interface was at 96khz, but it was really at 88.2khz. Modifying this setting fixed the issue.

I wonder how this could be avoided in future. Personally I would NOT recommend Mixvibes always force initialize the interface on startup, especially considering this is an Ecler Evo 5 and is used at live gigs (and an initialization pauses the sound for a second) and different DJs would be swapping on and off to use it.

Any thoughts?

No thoughts on this,

but there seems some trouble with sample rates indeed.
in the beta and the rc as well, i lost all vu-meters on 48Khz startup.
(Steve found this too)

But asides the Gain-Issue no probs for me so far.

OK, there seems to be an issue there, maybe due to some buggy ASIO drivers (that wouldn't be the first time ... ^^)! But I really don't get the second part, what do you mean exactly ?

[Stealthii]

Simply, if Cross is opened, and the sample rate matches the one currently set in the mixer, nothing happens, there's no disruption to live audio. However if the sample rate differs, the mixer changes itself to match what it's being asked to do (causing a brief silence in audio).

Update: on 48K startup the VU-Meters are broken, again.

[sylMV]

Every time you start at 48kHz ?

[Hannes]

Yes,
switching to 44,1 they come back and stay for the session even if changed back to 48K.
Broken at startup though.

btw damn fast response
