From the latest 6.15 build, the STK opcodes are still missing.

- here is the output of the console, followed by a test instrument for you.
- the test instrument does work in CsoundQt on the Mac and on the Terminal with the latest developer build.

    csounder From the latest 6.15 build, the STK opcodes are still missing.

    Yes, they will be added at some point in the near future, once everything else is sorted and we are closer to making a new release. Thanks for the example code, I will use it to test them when I add them in.

    @csounder could you please help @basswoman here ?

        giuliomoro Yes. I have been working with @basswoman and we have been making progress. I am looking now for specific models that I can share with her and that will be a part of the set that I deliver to you ultimately.

          Thank you so much guys! I think I got it. Now I'm trying to figure out how to make my 9 buttons to send midi note messages so I can play the tuning scale form "ftgen".
