Digitakt Auto Channel / Sound Browser issue

Digitakt is sending Sync & Transport to a Syntakt & Digitone. All good.

On the Syntakt & Digitone i’ve set their respective Auto Channels to 1 & 3. The Digitakt Auto Channel is 2.

On the Digitakt, Midi track A is set to Ch1 (Syntakt) & Midi Track B is set to Ch3 (Digitone)

When i select either Midi Track A or B on the Digitakt i’m then able to go into the Sound Browser on the Syntakt and/or Digitone & audition sounds via my Keystep. As i go through the sounds i can play them on that Keyboard. But when i go into the Sound Browser on the Digitakt i’m unable to audition the sounds the same way. The Keyboard won’t play them whilst scrolling through the list.

The Keystep’s Midi Channel is set to the same Midi channel as the Digitakt’s Auto Channel.

Does anyone know what i’m doing wrong?

Thanks
