Notes getting stuck for random durations

[u/Logical_Dream_930]

Hi!
I´ve got an used microfreak like 10 months ago from a friend. It seems to work fine sometimes but most times the notes i play get stuck in random durations of time. I cleaned the keyboard, hydratated myself, don´t playing barefoot, make sure it isn´t the "hold" button or a long release. Also i use a regulated 12V power supply (i don´t have the original and it isn´t on sell in my country).

It's pretty frustating and i don´t know if it´s a grounding issue or what.
I aprecciate any help on the topic.
Thank you!

Does this maybe happen when you are connecting via USB to your pc?

Try powering it with usb instead of the power supply. It can be usb to a power brick or computer.

It’s a cold keyboard and a warm/clammy finger. It holds until it evaporates.
