Hi,
I would contact Source Audio directly as you have a lot of their gear.
The key is learning to use the Source Audio Neuro Hub. Essentially you should be able to control all three of the Audio Source devices by sending Program Change messages.
This is from the Neuro Hub's Online FAQ.
This breakthrough in effect technology introduces Source Audio’s new scene saving functionality, enabling the creation of up to 128 single or multi-pedal presets (i.e. “scenes”), each recallable via MIDI Program Change messages. Simply dial in your One Series and Soundblox 2 effects as you would any traditional pedalboard, then hit SAVE on the Hub and your pedal settings are captured! Enjoy the power of one-step scene recall without the headache of navigating a complicated multi-effects processor.
You have to think if two signal chains. One for MIDI and one for audio.
Like a difficult piece of music, break down the problem into smaller pieces and learn each one. Start with figuring out the Source Audio gear, then move on to integrating other pieces of your setup. You have chosen a really complicated, but very flexible system. So take your time and get input from the people who made your gear because they know it better than anyone else.
