glossolalia Posted January 1 Share Posted January 1 Hi everyone, I just bought my first Line 6 product, the HX Stomp box. I've upgraded the firmware to the latest version (3.80). I'm using the studio setup with my guitar going to L/Mono in and USB out to my computer where I have it as an audio input in to Logic Pro (v10.6.3). The issue I'm having is that after a while (typically about 15 minutes) there is suddenly about a 1 second lag between playing the guitar and the sound coming out of the computer. There is no lag coming directly out of the HX Stomp via headphones though. Unplugging the USB cable and plugging it back in resolves the issue. The computer is pretty old (a late 2012 iMac with 16 GB RAM and quad core i5 processors) but I have had no issues previously uisng a Focusrite Scarlet audio interface for the guitar running in to Logic Pro with dozens of tracks, and the memory and CPU on the computer look fine. I've tried different USB ports on the computer with the same issue. I have the Line 6 Helix Driver2 installed but I had to use version 1.1.0 due to my OS limitation (I can't install any OS beyond Cataline due to the age of my computer). Does anyone have any insight in to this issue? Thanks! Quote Link to comment Share on other sites More sharing options...
lou-kash Posted January 2 Share Posted January 2 You may want to monitor everything through the Stomp, not through the Mac. Then you will have nearly zero latency on the guitar. In general, the Helix driver adds quite some latency on the Mac. I think you might get the best result when recording at 48 kHz sample rate – which is "native" for the Stomp – while keeping the Logic buffer as low as possible. But the lower the buffer, the sooner you run into problems with plugins. For the record, I'm doing multi-track recording – but not mixing – on a 2008 MacBook Pro running El Capitan because it enables me to use my two "antique" and "obsolete" FireWire interfaces together with the Stomp and a Roland Octa-Capture as an Aggregate Device, thus having 18 mic inputs plus the Stomp in total. It works, as long as you know the limits. In my experience, the worst bottleneck always was the spinning hard drive. Switching to a fast high quality SSD was a game changer, even on this old-timer Mac. What drive type does your iMac have? Spinning, fusion or flash memory? 1 Quote Link to comment Share on other sites More sharing options...
