Hi I found in this forum the information to make the 7in "work".
1) get a fresh gorgona and UPDATE
2) I am editting the files from windows using winscp editor and I sometimes have to edit multiple times and use the SYNC command otherwise the file is unchanged on the sd card.... so SYNC and reboot a lot to commit....
you have to change the framebuffer from fb1 to fb0 in 3 config files.
But for some reason I can't the see the 2 left controller areas. My screen seems not correctly centered and the 2 leftmost areas are past the left side of my pi7''.
Also how do you "enable" the touch controllers I can see that the touch in the middle of the screen works since I can press on "new" and then on the synth modules. But the 2 controllers area which I can see on the right seem not responsive...
I made a few pics from myscreen here: https://goo.gl/photos/7iq9WDAxaX8ZJeYa8
and here are some of the changes I did:
changed fb1 to fb0 in here:
commented out piTFT (needed?)
Now I do have a a raspberry + pi 7 + iqaudiao dac+ and some usb-midi converters.
Do I need anymore hardware to make all this work?
Also I just ordered an audioinjector board so maybe I'll be able to record or sample sounds and voices directly in the future.
