I have been using plugins almost exclusively now, and it's been annoying me having to manually switch presets. So I asked around and I was told I could use a pod hd500x to switch between presets on my plugins. So I bought one used and for the life of me I cannot figure out how to do it. I'm hoping, that someone here can help me out? the plugins I use are neural dsp plugins, if that's needed info
