Before I never tried more than 4 instances of vsthost and that was stable. I was when I got my new workstation with two cpus, that I noticed this: Going for 5 instances of vsthost, the 5th would simply not start. I searched internet for limitations/correct ways of how to connect everything. I tried connecting the live-hosts with different inputs and the same outputs(Analog 1 and 2) and also with separate inputs and outputs.
Then I tried different live-hosts together... The software I am using is Live Professor 2, vsthost and bidule.
When staring Live Professor 2 first, I notice different results each day. Yesterday, I was able to to start 3 instances of vsthost after Live Professor 2 was started. Today only 2. It seams like if I start Live Professor 2, then I can only start 1 -3 instances of vsthost. It varies.
If I restart, never run Live Professsor 2, only run vsthost, I can have 4 but no more, instances of vsthost. This is reproducible.
It is confusing...
