Thanks for your explanation.
I wanted a very blank preset to help myself learn all the connections and knob values, so I ended up making one. I'm attaching it to this message in case anyone else finds it useful.
In addition to having zero connections, all the knobs have been reset to the "default" position by double clicking on them. (The Factory "Default" preset has some knobs set to seemingly arbitrary values. For example, VCA1 Volume is at -7.11db, and the Dual Delay Left Time is at Tempo*3, etc)
Some exceptions to the "double click" positions:
* ADSR: A=0 D=0 S=1.00 R=0 (rather than all of them being 0.50)
* Sequencer: The "next step" knobs progress 1 to 8 (rather than all of them being 0)
All triggers are disconnected, with the following exception:
* VCA1 trigger is connected to "Keyboard Trigger On" (so that connecting an oscillator to "VCA1 In" works immediately - this seemed like a reasonable default)
Other than that, nothing is connected or modulated at all. Any further exceptions are errors on my part.
For a beginner like myself, it takes some work to get this preset to do anything complex, which is the point. But I find it more predictable than starting from the Factory "Default" or "1 Osc 1 Filter".
