Yes it's not exactly the same. It never really is with Axoloti, as we all have our own use cases, so don't expect an exact patch that does exactly what you are looking for, you probably have to work for it a bit.
But the pitch to note process is there, which is the core of what you are trying to do
So use it as a starting point and see if you can make what you need. Maybe remove everything else that the pitch analysis and go on from there?
What you are trying to do is something that needs a bit of "buffer time":
1. You send a trigger to activate the pitch analysis.
2. Then it take a short time to do the pitch analysis.
3. Then it can play back the analysed pitch value.
So there will be a bit of latency. The more precise you want it to be, the more buffer time you need = more latency.
So yeah. My advice will still be, check that patch and start from there, even though it's not exactly what you need. Alternatively you have to start from scratch.
