@joe_biomassa There is an execution order in orca, like @adrianf pointed out.
It’s easier to see how this works by looking at this example, notice how the first Va outputs nothing, for at this point in the runtime, there is nothing stored in the a variable. And Nothing is ever kept between orca frames.
.....Va
.......
aV5..Va
.....5.
.......
aV6..Va
.....6.
@Olivier I’m glad you figured it out. You will want to use MidiCC like @alanza pointed out, but to assign it to a knob id, just press enter on the operator, it will automatically bang it. It’s a good way to trigger something without having to necessarily send random values. All operators can also be triggered by pressing enter while selected.
@Tyler It sounds like you’re on Windows. There’s no way for me to test or debug this kind of issue. You should consider using a Linux distribution in parallel to Windows if you’re thinking about doing development or music composition on that device.
