Me? Pitch shifting is its biggest weakness. While it’s not terrible, it simply won’t track most chords. They know they aren’t that great. And they supposedly had a team come in there to work on it. But last I heard that was like when the HXFX just came out. If they improved upon on all the pitch shifting, I’d be hella happy.
Other than that, I wish they’d at least add the preamps to the HXFX. So you could use all those as well, preamps. I know there are platform limitations. But imo, the HXFX would kill even more if it provided those preamp circuits. But I know it’ll never happen. So I got over it. And I got a stomp.....haha damn you line 6!!!!
And the synths. I wish and hope they add another moog synth or two like a freqbox in the future. The ones on there are actually pretty nice. Just a tad limited. On the ones I use anyway. Not a huge deal. I’ve used the existing synths with my old band and it sounded great. So it’s not a huge deal for me. But it’s a minor, very minor gripe. I know L6 is always and progressively working to continue making the helix line get better over time. I love new updates. It’s makes my day. Week sometimes. Love my helix pedals. They just rule. Not a whole lot to gripe about. From my end anyway. But there are a couple things I wish they’d get improving on already. Biggest one for me, the pitch shifting.
Oh! And Adding a couple more crazy weird delays and reverbs would be amazing! Like an EQD afterneath or their rainbow machine. Some stuff like that. I’ll just stop now though haha
