Hi Clive, I realise that you might not want to hear this, but in my experience and if I was in your position, I would sell the Helix whilst there is value in it and buy a Vox ToneLab SE. This is what I did as I had the ToneLab before the Helix and having got another, I have not looked back.
You said yourself that you are not familiar with how the Helix works, so that is just stressful as they are not easy to work with even when you do know.
On the ToneLab LE, you can get a good Vox AC30 or AC15 sound through your system, then make the echoes for the songs you play and store them, just like the EFTP units did.
I recommend the LE version because all the stuff is there for Shadows echoes, including a swell pedal. On some models you can't get Shads echoes as good.
I can give you the method of doing that. If you are playing through an amp, you do not need the Vox AC30/15 as you already have the amp preamp that you are plugged in to.
I know it's not what you wanted to hear, but I sold my Helix well over a year ago now and have forgotten everything that I knew and I can tell you it wasn't easy even for me, I had many stressful hours trying to programme it, letting me down on a major gig by freezing was the last straw.
