Sequential Circuits Six-Trak, would power on but was function locked... then... one time, it powers and the buttons/keys are working! Then... it make some sort of sound!! Then... it had patches that don't make any sense!!!

Then, it goes back to being locked up. The spirit within briefly came to call. And then returned from whence it came. Glad to have caught the moment, till' I find a tech to fix it.
