So
NOOoOoooo!

I mean that:
In that case, every parameter is returned to a default position. The knobs on the panel arenāt motorized so they donāt reflect that value. But I do know the filter is fully open, modulations are reset to nothing, volume is up, Envelope at default etcā¦
Switching to manual mode sets the values to where the knobs are, I tried it and it does what it says, doesnāt change the fact that Square waveform isnāt audible with OSC2 (after making sure all the above is happening as it should).

Thanks but no, sorry 
As stated above, Iām not able to diagnose nor fix electronic instruments, and it is under warranty, which Iād void by opening it up.
Yep!
I usually prefer Manual mode.
I read somewhere the Basic Preset could be broken.

I wonder if it loads a user preset.
Have you tried updating the firmware, just in case?

For what itās worth sequentials warranty will let you do self repair if it is something like popping in a new board or reseating somethingā¦ worth getting in touch with their support, they donāt outsource there support team. I actually just had an interview for a role doing support there

Firmware update, Filter calibration is something you can also try. Very unlike it will let the sun in, but try everything before sending it in (guarantee, which by the way is godsend in such a case). Hope the bestā¦

VCOās are discrete in this one afaik, so sounds like whatever component is performing the pulse width modulation or buffering it into the waveshaper went out.
All shapes are based on the same oscillator core, which is working if you hear the other waveforms.
Dead op-amp pre-mixer most likely.
But I agree, donāt open and make use of your warranty.

100% if all voices have that problem.
So itās probably on the controlling side of the waveshaper. Mux or DAC-related.
Best of luck, Iām planning to get my hands on one myself.
Thanks for all the help. Iāve tried everything (loading presets, manual mode, initializing the presets etcā¦), not yet firmware but Iāll wait to hear from Sequential support.
While Iām an ass with electronics (thanks @trackerjack for confirming some of my assumptions and educating me some), Iām not with synthesis, nor that synth, Iām quite positive itās an electronics problem and will confirm with Sequential, and then use my remaining warranty.
@trackerjack I can only recommend the OB6, it has a sound and a way to stand out that I love deeply! I would say that quality is high, but hey, this thread shows that nothingās immune to breakage.

I guess Iāll wait to see what theyāre going to present at Superbooth.
But after a failed Syntrx b-stock adventure, the funds are technically available, well almost.
Thatās very subjective but I bought both a Syntrx and OB6, and the OB6 is the one Iām feeling wil never go anywhere. Iāve sold the Syntrx meanwhile and replaced it with something I like more.

Ahemā¦ ahemā¦ Feel free to judge me.
While looking at the Sequential website I looked at the latest firmware number, wanted to check on my OB6 so I turned it OFF and back ON., I have the latest firmware andā¦
That fixed the issue.
Ahem.

Glad that fixed the issue.

Shame would be there but itās overpowered by good laughter. An adventure for a Fridayā¦
Tomorrow I continue that Electro track I started this morning. Nothing groundbreaking, I make matter to play Live for an unexpected mini-gig (mini because the venue fits 20 people, or 30 tiny ones).

Sorry OP, I thought this was vintage. Glad you got it sorted. Iām out of touch with the synth market, esp the high end. Enjoy!

Great to hear! But what exactly solved the issue?! Just checking the actual firmware while tuning it off/on? After hours of trouble shooting you did not tried earlier? Nevertheless, now on to the electro track !

No problem! I appreciate the intention and no offense felt, at all.
And I feel sorry to have wasted everybodyās energy!
Itās funny how the good old turn it off and back on didnāt occur to me nor participants. Interesting social experiment

Nope, I didnāt try before. Just turning it off and on immediately. Somewhere a train of thought that itās analog and so it didnāt cross my mind, when in fact it running a firmware that controls the analog components.
