@Christoph-Hart it worked! can't believe it was that simple :)
Probably some valuable info for anybody using the table in scriptnode for more complex timings. thank you

@ulrik @d-healey @Lindon I just opened the best bottle of rum I could find and will have a little celebration - it works!

So I don't know what exactly has been the case - as self thought idiot that never learned how to use computers properly I know that with my first attempts writing scripts in whitebox packages for my installers I did some harm in the Application Support Folder leading to some weird stuff later on - now looking up all the files that I need to remove for a proper uninstall of Live there was quite a bit of stuff in the folders that I could have harmed - this is just me very vaguely trying to calm myself down that this will not be a common problem - if it happens - clean reinstall as instructed on the ableton website will do the trick ;)

I will implement midi out in current projects now and in 2 weeks latest I can tell you if it's safe or if I had to hire more support staff ;)

@Lindon @Christoph-Hart after posting this I started to write my own c++ code inspired by all the different algorithms available and can say that for "realtime" pitch shifting there is not really a one fits all solution but it's very doable and I got it up and running (but still optimising) . my use case right now is vocal manipulation and besides the fact that you have to really play around with window sizes, overlapping and so on - there is some other stuff that is needed for a industry standard result. I saw that autotune or little alterboy are reporting very odd latency to the host. so I figured there has to be additional sfft processing happening and it is resonance suppression. so before doing the actual shift I lower the magnitude of bins (above a certain frequency) to avoid resonances hitting the shifting algorithm. formant shifting sounds shit yet but I'm working on this right now.
Summary is that I don't see myself coming up with a node that I just use in different projects.
and if you go down the road, don't accidentally process per Frame or your computer will explode ;)

@d-healey I tested Live 11 only - as I used midi out in live countless times with other plugins so i can be sure it‘s not a user error on my side and if something doesn‘t work in live it‘s not something I can implement because a fair share of my users are using it. But of course it would be interesting if it works in other daws - I’ll see if I can find my little midi out test project and post a snippet for others to try. Now that I think about it I believe I tried in logic as well.

@Christoph-Hart 1024 samples (50ms) is what all the "realtime" pitch shifter plugins introduce.

the signal smith demo https://signalsmith-audio.co.uk/code/stretch/demo/ set to 50ms block size sounds on monophonic signals pretty much how you would expect "industry standard" rt pitch shifter to sound like .
would it be a crazy amount of work to basically replicate the web demo but with an audio stream?

the following looks even better for "realtime" processing and has a MIT license:

used in here:
https://github.com/jurihock/stftPitchShiftPlugin

I tried to implement it already but failed (I think because it's not c++11)

do you want to take a look? I think it opens up really cool currently not possible opportunities straight out of the box.

To test a RNBO node synced to host I made a little clock ramp project in RNBO - when trying to compile the node I get the following error:

❌  .../ramptest2.h:16:3: use of undeclared identifier 'setUseTempo'

                setUseTempo(true);
                ^

This is the RNBO setup

Am I missing something?

ps

@Christoph-Hart great! now with having rnbo I'm wondering if there is any way to get all the great midi manipulation possibilities from max/rnbo into hise. So basically something like a script Midi Fx. Is this somehow achievable?

ps

@Christoph-Hart ok it obviously worked perfectly fine in a clean new small project. Still it's pretty strange.. I think I deleted a xml network I initially compiled a Faust node in. I still could export the c++ nodes if there was no rnbo node present in the src. I couldn't find a trace anywhere of the deleted xml network but still somehow it's messed up and won't compile even if I delete the whole network binaries folder. is there any way to compile faust nodes independent of script networks like with rnbo nodes. it's super handy especially if you have nodes you often use in different projects.

ps

@Christoph-Hart I can't believe it - it actually was the calculation - but to be fair it just sets the maximum amount of samples 2^19 = 524288

I just replaced it with 240000 and no complaint.

24 hours of my life wasted for that haha

ps

@Lindon @ulrik @d-healey I can't believe it suddenly I am this one customer that has an unsolvable problem that you happily offer a refund.... I tried it on another Mac (intel) and it works here as well.
Clean install of live on my M1 incoming.

BUT WHY THE HELL DO OTHER PLUGINS WORK....

ps

@Christoph-Hart ok i managed to compile it - and if this is what you have heard I understand now why you are not impressed. I downloaded the vst and tested it and it sounds pretty different and has also a completely different performance. I'll do some digging.

ps

@Christoph-Hart one last thing - what is the magic trick to make it find the files referencing each other?

'../stftPitchShift-main/cpp\StftPitchShift/RFFT.h' file not found

#include "../stftPitchShift-main/cpp\StftPitchShift/RFFT.h"

ps

@Christoph-Hart haha thank you - I will have a completely non-judgmental look :)

ps

@Christoph-Hart can you share the node template with me? I'm doing something wrong - I get 2000% cpu even though I'm pretty confident I do the processing in buffers haha

btw in general It would be interesting to see how you write a wrapper around a juce plugin code and integrate it as node :)

ps

@Christoph-Hart can you point me in the direction how you included the library? i fail drastically somehow.

ps

@Christoph-Hart did you align the pitch shift with the timbre shift and set a timbre frequency to around 2.5 - 3ms?

if the formants are not shifted together with the signal it will sound strange :)

ps

@Lindon @Christoph-Hart
stftPitchShift is def the best out there I could find - it can do polyphonic and also formant shift.
2048samples latency is normal for pitch shifting audio (it's also normal that low signals sound bad when pitch shifted in those kind of plugins)
I'd love to see that implemented as well :)
