That's the edit screen for the octave effect. The footswitches are touch-sensitive, meaning if you touch (but don't press) them, you will go into edit mode on that effect. Playing barefoot or using your hand to select the effects can trigger edit mode if you hover over the switch before pressing it. If you don't want the touch-sensitive functionality, you can turn it off in "global settings>>switches>>stomp select". As @silverhead suggested, reading the manual will go a long way to understanding your new toy :) Enjoy!

For bedroom playing and recording, I would think your money would be better invested in a nice set of studio monitors. FWIW, I run my Helix through a pair of EV ZLX12P's and I think it sounds great. You can get 2 for the price of 1 of the Yamaha's.

@PierM Ninja on my 2nd post...might be an interwebs first ;)

I've replicated your steps using Pocket MIDI. It appears that sending CC #32 (select setlist) by itself does nothing, you must immediately follow it with a PC (0-127) to select the preset within the desired setlist. What are you expecting to happen when you send CC #32 without a corresponding PC? I've only had my Helix for about 6 weeks, but I've found this to be a valuable guide when setting up MIDI: https://www.thegearpage.net/board/index.php?threads/the-unofficial-helix-midi-guide.1954544/

Already did it :) But, you can't mention a firmware update and NOT expect this question: When are you dropping 3.10 and any teasers on what goodies might be in said update? Asking for a (very excited) friend...
