Thank you so much for the incredibly thoughtful response. I appreciate it so much. As you can tell, I'm a bit rough on my terminology. I thought that "real time" referred to being able to tweak parameters on the fly...seems that I was way off. I actually record using fx plugins in Ableton while playing instruments routed to the mixer > DAW > and then to Ableton...so I assumed that was real time. Thanks for the correction. So knowing this, I guess I DO NOT need to record in actual real time as I do not have latency issues. Does this change your explanation at all?
So, this is what I'm trying to do: I've been a guitarist for quite a few years and decided to start recording electronic music using guitars, along with drum machines and synths. I got used to using pedalboards and guitar effects, so my workflow is infinitely faster with guitar equipment. I currently need amp modeling for my guitar, AND I need effects for my synths...ones that I can control with knobs, and that don't suck my CPU. So basically, I'd like to use the Helix for playing guitar, and as a multi-fx processor that I can use to control the effects for multiple tracks.
Also, I have a Scarlett Clarett 8Pre thunderbolt going into my mac just for reference, so I'm sure I can use the outs to create more routing options. Now, from the first picture you posted, it seems like I can use up to 4 returns/ through usb, is this correct? So, theoretically, I'd be able to use the Helix's effects on 4 up to separate tracks? Thanks again, and I hope you bear with me haha.
