RANE Four STEMS Split Suggestion & Drift Issue

Device Model: Macbook Air M3
Version of operating system: MacOS 14.6
Version of djay: 5.21
Hardware/controllers used: Rane Four
Hardware Firmware Version: 1.7.0.8

I just bought the rane 4. I love the stem split option, long term this will be my go to mixing style. So much control. Two reasons why I can’t use it today.

  1. I have to turn on Stem Split when I load every song, it’s so annoying, I’m sure I’m missing something.
  2. Sometimes the vocal and beat will slowly drift away from each other. Not sure when it will happen so I can’t use this feature at all.

Wondering if these will get fixed or maybe I should return the controller?

Hi @Rocky3000, thanks for the details about your setup and the issues.

  1. Do you mean that you want a setting so the whenever you load any song it automatically performs a STEMs split?
  2. When this drift occurs, is this with Sync On or Off? Can you please try to capture a video of this, upload it to your Google Drive/Dropbox, enable sharing permissions, then share a link to the video here? Thanks!

That would be interesting to have. An auto load to stem split button or command. Right now I have to hit the button to split before playing live because of the delay is heard of the instrumentals switching to 3/4 channels.

Yes , if I turn on Stem Split, why should I have to turn it on for every song. If I turn on Sync it stays on for the next track, I don’t have to click Sync for every track. It should work the same way.

I only use BPM sync, not beat sync. If beat sync prevents the drift, I’d be willing to try it. I don’t have a video, it happens randomly and it slowly happens and gets worse further in the song. Sometimes I don’t even realize it until it’s too late. It’s definitely unusable especially since it isn’t easy to reproduce.

I figured out why it drifts and I can reproduce it every time now! When I have stem split on, if I increase or decrease the BPM and use the keyboard shortcuts it drifts, if I use the tempo slider on the Rane 4 it works flawlessly. I typically use the keyboard shortcuts because I can nudge it by .1 with every click. Here’s a link to a video of the problem 20240926_153823.mp4 - Google Drive I start hitting the shortcut about 5 seconds into the video and it becomes obvious the longer the video plays and the more I click the shortcut. I use ctrl/option 3 to lower the BPM on the left deck and ctrl/option 4 to increase it and I do the same but 8/9 for the right deck. I can reproduce it every time now but I have a work around for this issue.

Still would love it if it worked with the keyboard shortcuts and also need to keep the Split Stem on when I load a new song.

One more thing. Why is the waveform greyed out when in stem split mode. I still want to see the full waveform, only the vocal is visible in stem split mode

Hi @Rocky3000, thanks for the additional details and video. This is very helpful. I’ve shared these with our engineering team.

Regarding the waveform being greyed out in STEM split mode, this is intentional so that you can visualize which parts of the songs have been removed using Neural Mix. You can see this in real-time by using the Neural Mix EQs.

Hi there! Have you tried to disable “Tempo change detection”?

Thanks for the suggestion, I tried it. Same thing occurs.
