Playing the Keys - a search for an old thread

Hello pals!

I’ve finally set up my DX7 as the master keyboard. I can actually sit down in front of some keys and press them. I have no training or any experience in this field. Just noodling for about a year on hardware. It has been fun just experimenting but now I want to take a leap and actually learn how to do everything.

There was a thread on this a while ago but I can’t find it for looking. If anybody has a link for that thread I would be much obliged if you could share it. It contained some great information. (I have searched through the entirety of my posts but found nothing.)

I want to read sheet music and play chords. How do I start??
