If you go to the ReSound site for the Preza and look at the Smart 3D app brochure available under the Downloads tab, it shows a screenshot, presumably for a Preza, with a music program included on the program bar in the smartphone app, same as for the Quattro’s. http://future-resound.com/
Whatever HA you get, it’s a good idea to read/skim the user guide ahead of time and advise your provider what programs you want set up in the HA’s. The programs added to the HA may vary depending upon how the provider has their default fitting scheme adjusted in the fitting software. I recall at least one previous Quattro user whose provider had just installed the All-Around program and not much more to get the user started. It is hard to find in the Costco ReSound Preza literature any specific mention of the music program but an easy way to solve this is just to call your local Costco’s hearing aid center and ask - or visit that store area the next time you’re shopping at Costco (the HA center’s hours are more limited than the overall Costco store hours).
