most gear is center pin positive but the roland se02 is center pin negative. did you make your own 12v power plug for it?
for how long did you use it like that?
for a few hours - yes i make my own cables. i use these connectors
i’ve read from some people that the se02 is very sensitive to power supplies. but when you drive it with 12V i will try to build a proper one myself with a 12V powerbank and some dc-dc buck-converter to 9V. thanks for the information.
or usb powerbank & usb-to9v-ripcord
you know any ripcord brand that outputs stable 9V 2A? myvolts only gets 1A max …
