I'm using my father's Motif 7 purchased 14 years ago (I think). I've been playing on it for a while now, never faced any issue. It was locked up for 6 months because of quarantine and I was stuck at another place.
I played it for a few hours yesterday it worked fine. But today it freezed 5 times in a span of one hour. The keys go silent for a few seconds and then all the notes I've played while it freezed sound together.
I'm playing it with my headphones connected , no speakers, no usb cable, no sustain pedal .
I used it with logic pro x an hour before this occurred but had no issues.
Should I be worried or is it something that occurs sometimes?
