I am on PC, i7, powerful machine, 750W PSU, etc., Windows 7, 32bit, TC studiokonnekt 48 with the latest drivers.
I use Nuendo 5.5, the latest update.
I just purchased UAD-2 DUO and the audio glitches, stops, stutters - it just doesn’t work in Nuendo and nor the card, nor the CPU are overburdened - it just causes ASIO spikes, even at big buffer settings - I can make it work for a while when I change the buffer after inserting an UAD-2 plug-in, but if I insert another one, it starts to stutter again.
I also have two UAD-1 cards and they work fine, even with the same plug-ins inserted - when I assigned some less intensive plug-ins to UAD-2 - and it was not burdened at all - it didn’t work, while UAD-1 on the same system with the same plug-ins works normally.
Even stranger - everything works without a problem in REAPER, I could plug-in 6 Ampex tapes, NEVE 33609, 1081, etc. - all the CPU intensive ones and still it worked without a problem. But in Nuendo it doesnt.
So - the problem must be in something that Nuendo does differently than Reaper and something that UAD-2 does differently than UAD-1 and which is not problematic for Nuendo in the latter, but is problematic for the former - on my machine.
What could that be???
Did anyone have similar problems and solved them successfully? It seems it is not a problem in my system (REAPER works fine) and also UAD-1 work fine, there is something that UAD-2 DUO causes to Nuendo or vice versa that it doesn’t work.
