you can get access to all the input channels, you just have to use multiple input modules if you want to use all 16 in your patch.
I do understand that the way you assign them internally in the input module is perhaps more complicated right now than it can be, so can you explain how you would like it to work?
@tiger001 @aengine how would you like the input module to work so it is less confusing?
One possibility to make it less confusing is to reduce the outputs of the input module to 4, and then just have 1-4 per page of input jacks. So jack 1, 2, 3 and 4 on each row can be sent to out 1, 2, 3 and 4 respectively.
You can use multiple input modules of course, to get access to your 16 input channels. In this scenario you would need 4 input modules, each module giving you 4 channels to access.
The other alternative is to show 8 scopes on each page (2 rows of input jacks) and the 8 soft keys show 1-8. You can use them to turn the outputs of the input module on/off.
