The only real change I've noticed is now my volume pedal remembers its position. It never did that before. When I would turn on the unit the volume would be full on everytime regardless of the fact heeled the pedal cutting the volume before I shut it down.
The other thing I noticed, and I dont know if it had anything to do with the update is my Android phone will now play gapless music even while the wifi and data connections are on. I still get gaps when trying to play music from my Kindle.
Now for the bad, I now have the audible lag when switching presets. I never had that before the update. I always considered myself lucky until now. It is very noticeable when switching from rhythm to lead. Almost like the sound it cut off while the button is pushed though its the same lag even when you hit the button fast.
Another thing I noticed was the tones were not the same in my opinion. Though it kept all my presets, I still had to go back and tweak them for tone and especially volume. I had an immediate cut in volume even though all of the volume controls on the unit and in the presets were the same.
And is it just me, because I haven't actually timed it but the looper though still way too short does feel a couple of seconds longer. Probably just me for Im too tire of fiddling with it today to test my theory.
All in all I would have rather they left it alone until they could do a real update with some real improvements. I love this unit and had never even considered the Helix. But I am feeling a little disenchanted at the moment and a lot underwhelmed.
And just to add a rant....... This is suppose to be a HD unit but has way more SD than HD and some of the SD actually sound better Just my opinion I know.
