话题: Automix BPM issue
djkrysrPRO InfinityMember since 2010
Hi
I was running an automix while setting up at the beginning of my set and noticed one track sounded very slow, It was a 117 Bpm track but was running at 107 Bpm with the pitch slider @ -8.1%, I pressed the pitch reset button to correct it then waited to watch the next track mix in, it was a 122 Bpm track, as the tracks mixed the BPM moved up to 122 but as soon as the mix finished the BPM jumped up abruptly to 124 Bpm (+1.6%), the next track was the same BPM so nothing happened and it stayed at 124 Bpm, the next track was 127 Bpm as as it mixed the BPM moved up to 128.9 as it mixes then as soon as it finished it jumped abruptly to 132.21 (+4.1%), this continued throughout with every track at the wrong Bpm while playing.

Any ideas what is causing this?
I have just updated to the latest official build: V2024 b8336

What are your automixTempoMode, autoMixMode and autoMixDualDeck set to?

AutomixDualDexk ="No"
AutomixTempoMode = "keep pitch"

Altho it wasn't doing that, the pitch was moving all over the place, ranging from -8% to +4% just on the few mixes I observed before I stopped automix.
I am going to run it at home now and see what it is doing, if I can provide anymore information I will.

OK it's quite consistant.
I am running the automix on deck B.
I load the first track (128 Bpm) from the automix into deck B with pitch @ 0% then hit play, then start automix.
Next track is 117 Bpm and is loaded ready, now hit 'Mix Now'
Mix starts, pitch starts to move down to 117 Bpm during mix and reaches it at end of mix with pitch @ 8.5%.
As mix finishes the BPM jumps (not fades) down to 107.17 Bpm and pitch slider stays at -8.5%.

What is happening is the pitch fader is moving as the mix happens, (ie to mix into a 117 Bpm track from a 128 Bpm track the 128 Bpm track needs to be reduced down to -8.5% during the mix) then when the mix stops, rather than resetting the pitch to 0%, it applies -8.5% pitch to the new track, therefore reducing it's speed accordingly.

Technically it is 'keeping pitch' after the mix ends, but the pitch is moving during the mix, is this what was intended because it ends up with some very strange pitching.

Changing automixTempoMode to "normal" restores the automix method I am used to.

There was indeed a bug, an update will be available soon

Glad to see I am not going crazy. I was just putting on an automix while I was working and switching between an 80bpm to 120bpm on smart automix left the 120bpm track running at -25% and is quite jarring LOL

It should work correctly in Early Access build 8344

This drove me up the wall for the past 1 week. When is the fix coming?
