RANE Twelve platter speed doesn't change when adjusting tempo

I found an interesting phenomenon. When I move the pitch fader, the pitch on the djay iOS changed synchronously. And the speed of the music also changes accurately with it. BUT!!! The platter/motor of RANE Twelve runs in a normal speed! It has no change in speed!

I don’t think this is a perfect turntable adaptation, and it also affects my scratch practice. Because sometimes I need to use it in ±25% or ±40% pitch but the motor speed is not real.

Is there a way to solve this problem or will there be updates in the future?

Addendum: I have tested it with RANE Twelve and RANE Twelve MKII. They all have the same problem! (Yeah, I don’t know why the RANE Twelve works.) And Hercules Impulse T7 has no problem with it! They are all MOTORIZED controller!!!

Thanks for the details about your setup @ry900814. I will share this with the engineering team on Monday. in the meantime, can you please try to capture a short video of the issue, upload it to your Google Drive/Dropbox, enable sharing permissions, then share a link to the video here? Thanks!

Hi @ry900814, I spoke with engineering and this is expected behavior with the RANE Twelves. Changing the speed of the physical platter or making the pitch fader purely digital are both functional ways to apply a pitch fader on a motorized controller. We chose different implementations depending on the individual controller. You mentioned that this affects your scratch practice; could you please share some more specific info on how this affects your scratching? Thanks!

I don’t think it’s a good way to apply a pitch fader on the motorized controller. I mentioned that I also tested the Impulse T7. It has no this problem! When I increase the pitch, the motor run faster and vice versa. It feels like a real turntable!

Sometimes I use a scratch sample or digital scratch record that needs a very low pitch but the platter runs in a normal speed like pitch not changed. It’s not synchronized and feels strange!

For RANE Twelve, mixing or a little scratching is well. But it’s really really not suitable for professional scratch users.

In addition, the Serato has no this problem. Even the Virtual DJ performs good! I strongly agree that djay is a powerful software and has the potential to replace others. But please prepare the details first!

Okay, thanks for the additional info @ry900814. I’ll share this with the dev team.

It’s not a bug, it’s a feature !

The Twelve Mk1 and Mk2 have been a mess with Serato taking years to fix infamous sticker drift. And it’s still not really here.

At least you can’t complain with this issue here, except when moving pitch slider !
Off course all cue move from their landmark as the music stretch instead of motor speed change.

I found this behavior interesting because you can’t have it with Serato and vice versa.
What the point if all software behaves the same ?

Yes, you mentioned the issue of sticker drift. I also hate it very much! But that feature is not the key to solving this problem. I don’t think there’s any connection between the two. Serato does not solve it, but djay made it! Not only the RANE Twelve but also the Phase. That’s why I insist on using djay.

What I want to say is why different motorized controllers have different implementation effects? I tested the Hercules Impulse T7 and it performs as a real turntable. The motor speed follows the pitch, and no issue of sticker drift. I just want a real feeling of turntable on RANE Twelve.

Hi again @ry900814, as explained above, the implementation and behavior depends on the hardware. This is the implementation that was chosen for the RANE Twelve. The other implementation was chosen for the T7. However, the dev team is going to review this further and will consider changing this. I’ll report back here when I have more news. Thanks!

Thnx for this. Hopefully the same for the Rane one and Rane one mk2?

Glad to hear that and looking forward to good results!
