I 100% agree about LFO 1 being a mod source!!! 
Yeah I think I didnt make myself clear, I didnāt think anything had been drastically changed to the sound engine itself so Im sure an A/B would be exactly the same, its just the small tweaks theyve made to the second oscilator tuning the way the velocity modulation works and maybe some other things I donāt understand have made it play so much nicer in my opinion so much so that I didnt really like it before and now I absolutely love it. Its more immediate and Its easier to program a sound from scratch and get enjoyable results. When I first downloaded it I spent about 3 hours just playing and messing with stuff because it sounded so good to me. I made a post just before I downloaded it saying the way the keyboard responded to velocity was awful, then I downloaded the firmware 1.0 and it made it infinitely better I couldnt believe it and I couldnt be happier. Before this I was umming and arring all the time about selling it but theres no way now, its a keeper for defo
The only thing I donāt like is that it doesnt have 61 keys and LFO 1 canāt be a mod source.
Yeah, the weird dirty chorus in the left channel, I had to turn the chorus off. Itās like it has autogain, quieter when you play a note, then rises in level. Rebooted the keys, now itās gone. Seems like some weird intermittent thing. Well, that might be hard to trace. 
Sounds great otherwise, so happy round robin is back in Poly 1.
Hotfixes releasing today.

I just updated the s6 with the hotfix and I canāt put my finger on it but the synth sounds different and not in a good way, it sounds weaker, very quiet (always was on the quieter side) and the chorus is barely noticeable! maybe my brain is playing tricks on me but I was playing the synth the other night and it didnāt sound like this at all, it sounded better before.
Anyone else?
@chewyfinger Itāll be the velocity curve - youāll have to play a bit harder to hit full velocity. At lower velocity the patch will be quieter and with reduced filter ENV. The synth or patches havenāt changed, just the keyboard velocity curve, so midi will sound the same (or other midi keyboards) You can compensate if necessary by adjusting parameters on the patch (dynamics toggle, filter ENV amount, cutoff) We might still need to tweak the curve a bit but didnāt get much feedback from Betas. After upgrade you may need to auto tune filters again in some cases

@udo-audio That would make sense, I thought my brain was playing tricks on me for a moment! I would personally say that it has been tweaked a bit too heavily, I find that I have to adjust my playing style way too drastically, Iām almost hitting the keys!
@udo-audio Has the chorus been tweaked at all?
I updated my S6,
in my opinion the new velocity curve is too soft, I use my S6 for midi recording in Cubase, and monitoring the velocity input I get maximum 113 hitting very hardā¦
I would downgrade to 1.0, is it possible?

@Mauro @chewyfinger i agree. Leave it with me. I can feel it too, the response it miles better but not perfect and too different from 1,0. I will resolve quickly. Please do not try to downgrade as it will not work and may cause issues if the firmware file on disk does not match the one in flash

Thanks for your great work! I would like to gently & respectfully add that 3~4 days is maybe not enough time to give your beta testers who may have gigs/jobs/families a chance to respond with adequate feedback. So it seems we are basically beta testing in the public forum now on a release. I am glad that it is still possible to tweak the just-released hotfix, but just an idea for the future; Maybe give us a week to test new betas and provide feedback? Anyway Iām on a desktop model so this particular hotfix doesnāt apply to me, but am following all of this closely & passionately simply because I love this synth! Please donāt take my comment negatively, I just care and want to see it succeed and be as good as it can be. The major updates in v1.0 have taken the synth from a hopeful candidate all the way up to my favorite piece in my wind synth rig so Iām very grateful for your work.

hey all, new firmware seems great so far! love all the changes and maybe a bit niche but the steeper curves on LFO1 really make it feel much better.
just wondering if thereās any plans to fix the phasing / comb filtering issues when summing to mono in non-binaural mode? i know that you can send the voice spread to 100% and then sum to mono cleanly in your DAW etc, but itās just a hassle and upsetting to see this still hasnāt really been addressed for years now?
also wondering if this issue is present in the gemini?
The voice pairs are hard panned in the Super 6, so the codec is used to create a pseudo mono signal in 12 voice. Due to a few samples delay in the system if you sum left and right in 12 voice mode with voices not hard panned you can get some comb filtering. Leaving the voices as hard panned and summing to mono (or removing the right jack which achieves the same thing) will give you true mono in 12 voice mode. Unfortunately due to the fact this is hardware, there is no firmware update that could avoid you summing left and right unfortunately. Gemini and Super 8 get round this by having a clickless JFET switch that can sum left into right and right into left internally.

I held off for a bit to see if people would have any major issues with the update, but can confirm that 1.1 is working very well for me.
Iām loving the mix as mod destination and the vastly improved VCA level response to modulation. Round robin voice allocation fixes issues with using portamento in a poly mode, which is what I was hoping. For my purposes the velocity response in 1.1 is a big improvement.
Thanks to UDO for continuing to develop this synth.

In one video George states that Gemini has āstraight down the middle monoā(I think thatās how he says it) which implies that Super 6 doesnāt. Iāve also read, or heard, that there is always some artefacts present in the Super 6 preventing it from producing true mono.
Just to confirm, that is not the case? You say that the Super 6 can produce true mono with one of the techniques mentioned above?
After nearly four years of testing s6 firmware pro bono, customers finally get to test release candidate 1.0

To achieve a true monaural signal you need to disable binaural mode in either voice assign mode POLY 1 or POLY 2. Once the Super 6 is set to non-binaural mode, set LR PHASE (or PAN in this mode) to 100% so that each voice would be hard panned if both audio outputs were connected. (If you set LR PHASE below 100% in non-binaural mode, this will result in phase cancellation every time the signals of both audio channels overlap.) Finally, connect only the left audio output to your mixer or audio interface.
If you leave both outputs connected in non-binaural mode and set PAN to 0%, only an approximated centred signal will be generated due to hardware limitations (see Georgeās post above).

i just came back from a trip abroad, and iām just about to try the 1.1 firmware, to see if this solves my problems. (after installing v1.0 my mod matrix stopped working)
I do notice however, there is no init file in the latest download package.
Am i supposed to use the previous V1.0 init file?
So, to confirm, when performing the update via bootloader, the only two files that should be on the drive are xos_v1.1.bin and init_patch_v1.0 ?
I really want to get the new firmware up and running, but iām feeling super cautious about doing it right, now.
So i tried to install firmware V1.1. Same issue. Mod matrix routings have no effect whatsoever. My Super6 is still a near-potato. Be warned.
I have been enjoying the update but as a few have mentioned the chorus is now intermittently very noisy! Turning the chorus on causes very loud hiss that ducks when you play a note. It is unusable when it is noisy. I had to reboot twice and now it sounds ok.
