Great video. Can you tell me where you got the keyboard felt bed material? The felt on mine is a bit worn out

[@TwistedGridStudio]

I got it from a Canadian piano repair felt supplier. www.pianofortesupply.com/ They are super helpful and will even ship you custom felt cuts and sizes.

I just got a free DX7, but I'm not getting any output from headphones or main out. The battery warning came on the screen when it was powered on. Does that mean all of the internal sounds are gone? Help plz!

[@TwistedGridStudio]

Change the battery. That fixes 95% of issues. And yes, you'll have to re-download the factory presets via sysex after changing the battery. It's not too hard to do. Use a free sysex tool and follow instructions on one of the DX7 fan websites. You tube might have a tutorial on it somewhere as well. Good luck!

Hey! I hope you could help me out, mine has a problem with the analog/digital converter (that's what they told me, but what I know is that it just sounds distorted at the output) do you know how it could be fixed?

Change the battery. That fixes 95% of issues and is cheap. And yes, you'll have to re-download the factory presets via sysex after changing the battery. It's not too hard to do.

If that doesn't fix the problem, then you can look into replacing the DAC.

@@TwistedGridStudio I could actually fix it and it was just a battery issue, still, I need to find some midi to reload all data.
