Hi folks! I just got myself a super pristine one couple of months ago for my dawless live performance setup. I have an Elektron DT2, DN2, Moog Labyrinth, Metal fetishist and a Nord Drum 3p all connected to DB4 with a complex routing. I also purchased the Revival PCB to make DB4 mac / iOS compatible again and it works great for my needs actually. Apart from all those good things I have a strange problem about the tempo-synced damage effects like stutter, dicer, bitbash, saturator on the DB4. There is a super annoying slight drift goin on when I activated the tempo-synced FX’s. Whatever I tried, those damage FX’s drifts slowly. Internal / external clock, BPM detection, DB4 own Midi clock determined from the menu etc… doesn’t matter, they just drift in a very annoying way like in a loop, like one of the machines is slightly slow or fast somehow. Then I just find out that when I send the master clock via iPad AUM app with the Revival to DB4 the stutter effects doesn’t drift but every time I stopped the music then hit play again the stutter FX starts from a different point like an LFO without a reset. So it looks like the DB4 BPM conscious damage effects designed to work like this which is weird and make those very cool FX’s unusable. I know I can correct the timing/ position of stutter or chopped audio by the FX adjust scroller knob to move the position of the chopped audio but its not an option during a live set. So I cannot turn on those effects instantly without cueing it cause I’ll never know where it starts to chop the audio. Btw, I dont want to use the iPad and AUM always connected to DB4 and if I set the BPM manually on both Digitakt and DB4 manually, those damage effects will drift eventually but it can be tolerable if the chopping/ stuttering position could be in the same position everytime I engage the FX.
Did anybody ever noticed that problem? I know that there is no perfect gear but those tempo-sync FX’s shouldn’t work like this logically I think… 
cheers !
