Monitoring latency is a problem when recording, especially if you have lots of other tracks with lots of plugins active at the same time. There are things that can be done like pre-rendering all the tracks prior to recording, but depending on how you work, that may be a serious buzz kill. It is for me. So what I like to do is run a standalone instance of S-Gear (or Guitar Rig 5) and I monitor the guitar from there while I simultaneously record the guitar in Reaper to a track with Helix Native plugged in. The latency is pretty much non-existent from the standalone and I get a reasonable approximation of the tone I want for monitoring. This is the main reason why I'd love a standalone app for Helix. All the vst hosts I've tried are far more hassle to set up and run compared to a standalone app.
