Thank you for the informative and helpful post! The reason we included the ability to upgrade our Stompboxes is so requests like yours can be implemented in future updates.
The updates we have released so far have been largely based on customer requests, including sending the Feedback control to 110% for self-oscillation, and doubling the amount of space for saving Presets.
We are currently working on the next release which will address many of these MIDI requests. Your Clear Loop suggestion has been added to the list of feature requests.
At this time there is no source code editor for the Stompboxes, although there is one available for our rack processors (VSIG.)
We appreciate your input and please be assured that we are listening!
