Well I just turned multicore/multiprocessor support off in LIVE and cured the problem! Thanks for that guys, you nailed it. Hive and Diva problem sorted

edit: Although having said that, I can play 11 instances of Hive in maschine without a problem but not more than 3 in Ableton. That's better than none as before but still!

Can you point me to the part in the User Guide where it's recommended to turn off the Host Multi-Threading ?

This was the line I was remembering:

Multicore causes Diva to distribute voices...Also, this feature might interact with
multi-threaded hosts in an unpredictable fashion (we haven’t seen any problems so far).

I italicized the part I had forgotten. So yeah, the host's multi-threading is probably not the issue. Nevermind, apparently that worked... >_>

But if you turn off Live's MT that means everything else is now not taking advantage of multiple cores. Audio, other plugins etc.

I think it would be better to turn off MT in DIVA when using more than one instance rather than turning off the Host's MT.

But anyway you're saying that in Machine Hive is almost 4 times more efficient than in Live. I don't own Hive, Machine, or the latest full version of Live so can't be of any help there but that definitely doesn't sound right. Live is one of the most popular DAWs on the market so you'd think it would be one of the more efficient.

Live isn't that efficient. But neither is Maschine. But then again, it's most certainly not that inefficient. Still don't know what to make of this.

Hive doesn't need that really, it's so low on CPU that the CPU meter hardly ever shows anything.

Yeah, but that's not at all why I mentioned that.

Hi, I swapped my fireface ucx over to firewire and tested it again and this time I was able to run Hive with multicore support enabled in Live and managed to get to 23 instances of Hive playing three note chords with the Bright Stack preset loaded! The Fireface has also stopped turning into "bitcrush mode" ever half an hour too which I mentioned before.

I can also run no more than 3 instances of Diva in multicore mode playing 16 note chords in divine mode and turning on multicore support in Live at the same time actually helps a lot.

This is odd because according to the UCX manual firewire is supposed to be less efficient than usb.

I wondered whether it might have something to do with something I read in UCX manual about it not being connected to its own USB bus as the usb cable is plugged into one of six usb ports in the back of the PC with all the others being used by something else.

Something else unrelated that oddly isn't mentioned in the manual is that when connected by firewire the UCX powers itself via firewire cable and doesn't need the power supply!

This is not weird, FW port can provide enough current to power the audio interface.

Is it in the manual? I couldn't see anything.

Did you checked the CPU temperature? Overheating causes this kind of problems often.

No but ive got a liquid cooler if that makes any difference

Check temps any way, if thermal paste wasn't applied correctly it can cause problems.
