You'll have to disable the delay compensation for the VC in your DAW, because although while playing live or recording it will play normally, when playing back MIDI the DAW will play ahead of time to compensate for the delay of the USB connection. Besides the analog outs, the S/PDIF out is also a good idea if you want to avoid sampling noise.

What I wrote above is in reference with running VC in the DAW and sending MIDI part output to the physical outs. If you don't use VC and send DAW MIDI track output to the "synth out" MIDI port, you will not experience the delay compensation issue.

I switched to that recently,



the Virus is stable when you are not sending audio through the USB.

Of course, this way, you will not be able to use the VC and the TI concept.

I hope your studio is in a well ventilated room (e.g. not a basement), I just can't stand the smell of a newly carpeted room. And now to business...

You have 2 ways of sending the part to the analog outs: one is the "D" button which stands for direct monitoring, and the other is selecting one of the 3 outs as the destination of the part which you can do from the common tab or by command+clicking the said "D" button.

The problem is that I don't think there is a way to disable delay compensation for a single VST in Logic. You can switch to live mode which will make it play just a tad earlier, or you can just go back and forth between VC for designing and copying sounds to ROM and pure MIDI (external instrument plugin) for playing.

I use my Virus this way... works more reliably than using USB Audio via Virus. I think the amount of data going through the USB port as well as Midi data is half the problem people are having with sync issues too, and Analogue outs are just fine for me, as long as you use a low noise good desk, or SPDIF outs even... but you are limited to 1 X stereo out instead of 3 X Analogue outs.but it depends on your requirements.

VC works fine using Cockos Reaper DAW for me this way too, so long as you select Direct monitoring & Live mode...
