The I/O page is very easy to use, and I like the matrix layout, but I have an issue with the fact that you have to scroll around the matrix with your finger, and it is extremely easy to cause accidental patch changes on the mixer screen or the ipad app when trying to scroll around.
There either needs to be an undo button on this window, or an option to use a long-press or double-tap in order to make a patch change. Make it a user-configurable feature in case some people really don’t want to slow down the patching, which I could see when setting up a brand new patch like in a rental or touring scenario. For HOW and install applications, the patch rarely needs to change.
The only way to do this now is to save an I/O library patch every time I make a change so that it can be loaded as a fall-back, but if something got accidentally changed during an event or shortly before, there could be disaster.
