Change in plan: I ordered an Ultra this evening and I'm going to return the Standard.
Today I ran into a few scenarios where I either didn't have a feature available while building a patch, grabbed a few patches off of Axe-Excange that I wasn't able to utilize in whole but demo'ing pieces at a time I wanted to be able to evaluate their utility in full, and finally ran short on processing power while building a patch I would definitely make use of IF I were able to. Most of this didn't matter to me as I was just playing around with sounds I'd have no practical use for. Running out of processing power building something I would definitely use after a bit of refinement was what tipped the scales. I had the means to sport for the Ultra when I bought the Axe-FX. I just did not foresee the need for the Ultra. Oops!
I suppose I could have saved myself the cost of shipping back and forth on the Standard if I had purchased the Ultra 'just in case' but it just didn't seem worth an extra $500 for 'just in case' at the time. It does now! Since I've now seen fit to pay that additional $500 I'll definitely be playing around with the additional features in the Ultra to see if I can find uses for any of them. At the very least I'll be able to demo any patch shared on Axe-Exchange. Oh well - live and learn.
