I had one broken key and several loose/clicky keys. I sent the MODX8 back to Sweetwater under warranty. After 4 weeks I got it back. Within 2 days the same key was broken.
Very sad. Yamaha used to make pro gear.
Anyway, if I need to repair this after warranty expires, what do I need to know?
I definitely can’t spend the money required to ship it and pay for repairs.
