Hello all. First time posting, new Helix user here(approaching a month).
I have to agree with the consensus that the helix, even after the latest update, does not track chords well, at all. A great example that everyone can try is play the intro to Wish You Were Here. The helix fumbles at replicating that hammer down from open A to 2md feet B while maintaining the G on the 6th string.
Now to reply to someone's comment about how there isn't anything that can track chords... Play the 5 year old Electro Harmonix HOG2. You get full chord articulation, mind you with a slight bit of latency, which I can handle.
The hog2 can even glissando between two chords, freeze chords, pitch shift while freezing a chord, and allows 8 shifts of pitch all at the same time from - 2,-1, 0, +1,5th, +2, 3rd+2, +3, +4.
5. Years. Old. The helix should be more than capable. At the expense of a couple of blocks? Or 5ms or so of latency, sure! I think we can live with that.
Also, I will commend the helix for its low latency processing on pitch shifting. Now let's just see if we can convince line 6 to improve that pitch shifting algorithm.
