your panel looks nice to me. I just don’t want to help people who are selling their panels. When your panel is fininshed I would publish it here on the Ctrlr site. You will get more help when everybody can see that you are not making business with your panels.
btw. global vars are called k0 to k9, then next one is ka, kb etc. up to kf then it goes on with o0, o1 etc. up to of. Very strange naming convention… I don’t know what’s the next one after of.
about the fixed values: this is probably a bug in the fixed slider. It just does not react as expected. What you could do is making another box (an uiLabel) and set the fixed slider by a Lua script according to what is entered in the uiLabel.
