BeatStep – Notes changing randomly in sequencer mode

Step BeatStep Pro
#1

Hi,
I’m having a strange issue with my Arturia BeatStep (not the Pro version).
When I create a pattern in the sequencer — for example, just one step with a note — the CV out changes the pitch automatically every few steps. In my case, every 6 steps the BeatStep changes the note, and then repeats the cycle, even though I’m not programming any variation.

Here are the key details:

  • Only one note is active (e.g., step 2).
  • I’m in Chromatic mode, no custom scale.
  • The Probability for the step is set to 100%.
  • BeatStep is connected via CV (V/Oct) to a modular synth.
  • No randomization or pattern chaining is enabled (as far as I know).
  • Firmware is up to date.
  • Tried different cables and ports — the issue persists.

Also, on the BeatStep’s tempo/value screen, I can see that the value changes by itself, even when nothing is being touched.

I’ve attached a video showing exactly what’s happening.

Has anyone experienced this? Any help would be greatly appreciated — it’s frustrating not being able to use it reliably.

Thanks in advance!

HI @Vlad1 and welcome to The Sound Explorers Forum!

I do not own a BeatStep and a look through the manual didn’t enlighten me any, so i think the best course of action for you at the moment would be to log into your account to contact Arturia Support who should be able to assist you.

HTH!
