I'm trying to record with my guitar plugged in to a Focusrite 2i4, with one of our beloved VST amp sims (tried LePou and TSE) and an impulse loader on the armed track with monitoring on. Everything (including live monitoring during playback) is fine, although with pretty high cpu utilization, until I press record, then the sound completely stutters...
My computer is a bit aged (has a C2D cpu), is it just to weak to accomodate live monitoring and recording with VST amp sims? Or are my disks too slow? Anyone running a similar setup?
Yeah I play thru and record with VSTs 90% of the time. The only time i stutter is when I have too many other plugins open while trying to record or if I have multiple instances of guitar plugins on different tracks or I have them set at higher resolutions.
I know TSE and all the Lepou stuff has low/high quality and stereo switches and if you're getting lag during recording, sometimes it's best to run the plugins in low quality and mono until you're ready to mix. Also look into your interface's bit rate settings. That can have a big effect not only on latency but whether you will get skipping or not. My CPU is old too and I pretty much have to render drums and anything more than 2 guitar tracks separately when I plan to record more with live monitoring through Reaper lol.
I know that the new TSE stuff (x50, x40) is very CPU demanding and the Lepou stuff isn't that much better. I find that recording w/o a tubescreamer VST also helps free up CPU bandwith. Of the free plugins, Legion or TSE x30 seem to be the best with the least lag and still sound tight enough with the bass knob slightly rolled back. Then with mixing, if I prefer the tightness / gain compression with the tubescreamer I can add it back in.
For the non free sims, Revalver and TH2 seem to have pretty good latency if not better than the free ones. Actually TH2 has really good latency but that program is expensive.
So yeah, check your interface settings, set the VSTs to low quality when recording and record in mono and render tracks separately if you have to for playback/recording :P
