Nice Larry!
I've never seen it discussed anywhere, but I want people to note something that will never ever happen when playing an acoustic accordion, something that mostly a more experienced or advanced digital accordionist will do;
With acoustic accordions we switch registers and play the same notes out generally in the same manner and this gives greater variety. This is great, sonic variety is wonderful!
However, when a digital accordionist changes to a different "instrument" a higher, truer sense of that new instrument happens when you change playing styles to match the characteristics of that instrument.
For example when Larry switched to a saxaphone sound, he reverted to single notes and different phrasing vs when playing accordion, and it changed again when he added the mandolin sound, holding the notes a little longer to accentuate the tremelo of the mandolin sound.
It's these little things that add a lot to the level of enjoyment of the experience, at least for me, and displays a cognisance of the instrument that is a little bit above the average... am I alone in this mentality?
