Any wizards in here who wanna help me out?!
I have bought a very small synthesizer called FLASH, that I have connected to my YAMAHA CS2x MIDI OUT port.
This small synthesizer contains microtunings. I am told I can access them by doing CC (control change) from my buttons on the YAMAHA CS2x.
I am attaching a link to my Onedrive cloud, which contains pictures of the YAMAHA CS2x, YAMAHA CS2x manual and the FLASH synth manual.
About MIDI starts on page 72.

Thank you for your help!

regards,
Erlend O Albertsen
