That kinda depends on you and your overall chain.hi Synetos:
After running cubase(Digigrdi lv1), how much buffer is suitable for programming and large projects.
I have been at 256 and can't be lower anymore.
If I am running 96k, I can run with 256. But, when I am tracking live instruments or vocalists, I run as low as I can. When just mixing or using midi only, It doesnt matter so much.
So, unless you are overdubbing and playing in live via keyswitches, then you can run whatever latency level you can tolerate. I am okay up to 8-9ms, but after that, I dont like it.
