Hey Torch - Be happy to start a new thread when we get started with some SysEx examples. Interesting request of doing that without a computer. Never needed to do that and I'd have to look and see what SysEx functions I could send via our primary controller.
To get things started, we plan to show a few examples from a DAW and let's see where the thread goes as folks comment. I'd be interested in learning more about what you suggest. In the meantime, we are working on a short "How to" video this weekend to show using Cakewalk Instrument Maps with an SD1000. Let me put a reminder on my calendar to bump up the priority of putting together something on using SysEx.
