The guy that helped me out was Christopher Edwards. Honestly amazed that they took my enquiry seriously, say what you want about Behringer but this is the first time a company has released a firmware update for me 
It really is a gamechanger feature (that the original MonoPoly had) so I hope you guys enjoy it as much as I am!

Thanks for the follow up!
I admittedly forgot about checking it, sorry.
Nice to hear that Behringer is fixing issues with the synth. I have issues with the glide.
Have anyone noticed that the glide doesnât work when you play two or four notes in polymode?
My settings:
Polymode on. Portamento is turned up. Arp range is set to 1 or 2 octave. Latch on. Play two notes one octave apart for example. No glide. Play 3 notes. There is glide. Play 4 notes. No glide. Turn full range on arp and there is glide. Strange isnât it? I have tried both the original portamento setting and improved in the synth tribe app. Same behavior. Anyone wanna confirm?
Hi, i have a Behringer Monopoly and everything worked fine until today :â(
I canât trigger notes via the keyboard. I mean, it triggers a note but it only sounds a simple tone that doesnât keytrack, only plays the same note over and over again. The VCOâs lights are always on as if i was triggering notes non stop. Itâs weird because everytime i reset the synth the âsoundâ only comes back like if i were on 16â (lower octave range) on the VCO. But if i move it up it resets and transposes one octave up. Strange.
Also, the Key Assign Mode remains unusable i donât know why and its only on Unison Mode , the effects section is Off and no matter how i press it it doesnât lits up, leaving this section of my synth unusable.
Iâve tried sequencing via a Korg SQ-1 with his CV ins and it works perfectly this way, but i dont have access to other voicing modes and effects.
Arp is off, obviously.
Please help me :â((((

Maybe open it up and see if there is a ribbon cable connecting the keyboard to the main pcb. Try reseating it and see if that fixes the issue

Have you tried connecting to the Behringer app? Just wondering if that and/or an OS update might help if itâs had a wobble?
Solved. A guy from Youtube told me to literally let the synth On for like an hour and it fixed itself. Wish every problem of life could be solved like this.

Behringer monopoly owners - now that youâve had it for a while, how are you finding it? Howâs the build quality? Does it stay in tune? Any known issues?
Cheers

Wondering as well. How does it feel after a while?
Could this make a âpoor manâs Performerâ?
Iâm having the exaclty same problem.
Iâm waiting an hour to see if will be fixed.
Did you see this solution in a video or in a comment?
sorry for the late reply.
You can see the error here: https://youtu.be/pX05TFfxeQc?si=IsU50R9RQTrMl4ca
Thereâs a few other videos if you look enough.
Itâs a great synth. The sound is awesome, the build is pretty damn solid, the keys are really good to me (not really a skilled pianist). Kinda buggy with the VCA Bleed problema and allĂĄ but itâs a great instrument. Seen here in my city used at around $500-$600 USD, itâs a great deal if You asked me.
Picked up a unit displaying this exact issue. As others have reported, fixed by leaving to run for nearly an hour. On further testing, I seem to have prevented the issues return by leaving plugged in, socket on and power off. Wondering if itâs a power management thing then. Will raise with B if I get the chance but would recommend at least trying, might solve.
Hi all,
Are these any good? And by that I mean, can you do that round robin Robert Hood techno thing on it like the original Korg?
Donât know if itâs fixed but thought Iâd draw your attention to an earlier post discussing the round robin behaviour you asked about.
