Tópico: Virtual DJ and Denon SClive 4 pitch
loading songs in decks 1 and 2 the sync buttons automatically light up and I can't turn them off. both songs will have the same tempo. the deck that is playing controls tempo on both decks. I have to stop deck one and press play on deck 2 and then move the pitch sliders to get it to the proper tempo but it also changes deck one tempo. any idea's?

go into settings and type
pitch
check out the setting descriptions
 
tried that to no avail
 
The purpose of Ableton Link is to sync tracks, so if you don't want to sync the tracks you should indeed turn off Ableton Link
 
hmmm. trying to sync 2 macbooks.
 
Ableton link is not the issue as it does it when its disabled as well
 
You can disable autopitchlock if you don't want the 2 tracks pitch to move together after sync.
You might also have smartplay or autobpmmatch enabled
 
yes I have toggled them all off and on with no change
 
Based on your description, you definitely had auto pitchlock and possibly auto bpm on/other auto sync options and @Adion mentioned.

If you haven't already, switch them all off on the deck (their description and how toggle them from the default interface is stated in the User Manual here).
Also, pitch lock may be a "sticky" setting (@Adion and @locodog pls correct me if I'm wrong), so if you still see the sliders moving together, you may have to add this to a custom button and click the button afterward before trying to manipulate the pitch again:

pitchlock off & beatlock off
 
auto pitchlock and auto bpm on are off. as soon as i hit the ableton link button the tempo jumps to 120bpm and I can't change it until after I hit the play button
 
So earlier on you said this:

That implies no link session and that can only really happen if you have autosync and auto bpm options on.
A link session is different - I've not personally used it, but from what I understand the tempo that will be used for the grid session when a new participant is what is already established by an older participant.

Maybe you could give more info on the session (what applications are the participants, which app started the session first, the VirtualDJ instance you are talking about or otherwise)? It would probably be expected that, if VirtualDJ is a later participant, it would sync itself and play relative to the established tempo/grid of the session (if that was at 120 BPM) and then the tempo changes on the deck would register to change the tempo of the session.

You probably would want to disable the regular autosync options just to ensure/understand the behavior too.
 
just notice that the tempo drift between the 2 decks as well. both set to 100 the run out fairly quick
 
I didn't think ableton link was the issue ( when I turn it off I still couldn't adjust the tempo of deck 1 ) but discovered after I hit play I could adjust it but it always starts with the previous songs tempo, I have to move the tempo fader back and forth then center it to get correct tempo. I just have virtual dj and a Denon SClive 4 running. I wanted to link my 2 macbook pro's together to run visualization software on one but don't have it turned on until i figure out why ableton link is messing with my deck
 
everything works perfect until I hit the Ableton Link button then deck 1 is messed up
 
 
So i just tried this with two different ARM based MacBook setups running VirtualDJ (one connected to a DJM S11 and Phase HID, the other connected to a DDJ 1000).
The answers:

  1. A session is started and continues to exist as long as a participant is still running VirtualDJ with the Link Plugin
  2. The one in the session the longest along with the last BPM change seems to dictate the BPM that a new participant would get
  3. The BPM sent for session changes/the ability to change the BPM is not registered until the deck starts playing


So that behavior seems reasonable based on the spec - a non-playing deck doesn't really contribute reasonably to the session - there is nothing actually playing there to sync to/read BPM changes from (the BPM is actually 0 in that case in terms of the definition of BPM (Beats Per Minute, but it's not playing so no Beats are actually happening Per Minute, Second, or any time measure), but it can show the current Link session's BPM.

Your video didn't show the other participant, but I would guess that you had enabled Link on the other machine on a deck/some other Link software and played a track there at a BPM of 74, so the machine you showed, on Link activation, shifted its BPM to the playing deck.

However, I've noticed one thing that is weird to me, or at least I may not understand the behaviour:

If I disconnect each VirtualDJ participant in the session (adjusting the BPM of the track last participant before disconnect) and then I reconnect one again, the new participant adjusts its BPM to the last reading - i.e. the Link Session's BPM seems to still exist from VirtualDJ's perspective, given at least one VirtualDJ participant started/joined it, regardless of if the Link plugin was disabled on the deck for all VirtualDJ participants before doing a rejoin of one of the VirtualDJ participants.
This behaviour is only reset if I restart VirtualDJ for both participant machines.

@devs is this normal? I would have thought that disconnecting all participants from the Link session killed the Link session itself.
 
there was no other participant. just one macbook and my Sclive 4
 
So I pretty much tried this - I could not get this behavior unless a session was started with another participant that contributed a BPM.

Without seeing your sync options it's not clear what's happening here. Maybe provide a video that shows everything:


  • Disable all auto sync options (show how you did that too on both machines)
  • Close all instance of VirtualDJ and restart them
  • Connect all controllers
  • Do the sequence you did (show the software screens on both machines too before/after every step)
