HXFX - stereo path merge to mono in Helix Posted September 26, 2020 Hi, I just solved the issue! Hxfx behaves just the same way the helix is - if the right output is not connected, signal merge to the left. The problem was probably in my presets. I imported them from helix and even everything was set properly, some settings from helix stay active but not visible in hx edit of hxfx. After I copy everything block by block to a new preset, problem disappeared.
