Chas, I think that, if the whiz bang features inspire you to spend more time sitting at the instrument, becoming a better player comes automatically with that. And if the features make what you ALREADY play sound better, that becomes the reason to sit and play for maybe an hour a day when it used to be ten minutes a day, or whatever.

Seat time, as any racer will tell you, always ends up being better lap times..!

Also, enough seat time behind a new arranger usually ends up with a curiosity about whether any unused features can help you sound and play even better. It’s a feedback loop. Stagnation is the enemy. Some people have enough drive to just sit and put an hour or two into excersizes (and by that I don’t really mean just scales and arpeggios, but anything that improves your performance like mastering bending lead solos, or working on chord voicing for guitars, strings, horns, whatever) with the gear they already have. But others do better when the inspiration of a new whiz bang arranger graces their music room.

Whatever it takes!

The only way a new arranger won’t make you a better player is if you don’t play it!
