Just to put on a perspective. IMHO.
Maybe complaining that T-1 doesn’t have a screen it’s like complaining that the piano doesn’t have a screen.
Not having a screen on the T-1 doesn’t mean you don’t have visual feedback (just like the piano).
I use it with a visual feedback all the time, you just need to press the button twice or keep the button pressed actually.
It’s an instrument. You learn to play it by developing ear and muscle memory. I have had mine for almost 12 months now and I am just starting to really PLAY it and I am still learning new tricks/functions/skills.
I understand that, if you don’t have the time to put in, it’s better to focus on something else because this could be frustrating in terms of remembering combos and hidden functions.
But, if you do put your time in, it’s really rewarding on the long run.
