giuliomoroRunning multiple MIDI devices is not a top priority, but it would be nice to connect a hub to the bela and just use any of the controllers that one has connected.

The strange thing now, is that realtime audio in does not work with the latest bela2 (it could be connected perhaps?)
- and so, this might not be portMIDI related.

in the examples, the audio loopback still works, but none of my 50+ audio examples work any longer
- and the console does not report any issues.

As a test example, you could just use the previous example with the 'ins' opcode
- this works on the laptop and this worked previously

I tried forcing the comandline with a -iadc and -odac and --realtime and --daemon, but this made no difference.

    csounder As a test example, you could just use the previous example with the 'ins' opcode

    which one please? I am not sure I understand which one you are referring to.

    In the meantime, you can try 6.15-bela3 release:

    • restores MIDI functionality (or at least it should, let me know)
    • adds support for Trill Craft. You have to specify 30 "touches", and the touch size for each will be the reading from each individual pad ( I think -- completely untested)

      giuliomoro I will try the latest version, and solder up my Trill Crafts for those tests too!

      Here is a working MIDI .csd, in the CsOptions section, you will see command lines for:
      previous Bela 6.15 (with no multiple MIDI support, but excellent MIDI)
      Bela 6.15 v2 (with multiple MIDI support, working!... but many Mode switches and Dropped blocks)
      the command line settings I use on the Mac, to run Csound with multiple MIDI devices in the terminal

      As you will see from the .csd below, it is reading MIDI CCs 1-9 (typically from my nanoControl)

      giuliomoro to test and see/hear if realtime audio in is working again, you would use the version of the stereo-delay instrument that includes the two uncommented lines (and plug in your iPhone or a Microphone):

      ainL, ainR ins
      ain = ainL+ainR

      to test if the soundin opcode is working, you need to add your own mono sample to the project and uncomment
      the ain line with the soundin opcode.

      ;ain soundin "sp_hellorcb.aif" ; Does NOT work on Bela.

      • you should replace "sp_hellorcb.aif" with the name of your uploaded mono sample.
        It can be either a wave or aiff - for instance

      ain soundin "sp_hellogiulio.wav"

      and if instead, you were to uncomment the line using diskin opcode, you will hear/see that it does work

      ain diskin "sp_hellorcb.aif", 1 ; WORKS on Bela

      I will try your latest build now.

      Best,

      -dB

        giuliomoro I would love to provide several additional example instruments that would show additional ways of working with the Bela and Csound - and that sound great too! I will pull them together and you can see which you might like to include.

        giuliomoro I am trying the 6.15-bela3 release now.

          giuliomoro 6.15-bela3 release - initial test

          1. not sure it was installed correctly? sorry
          2. as I noted previously, in 6.15-bela2, realtime audio-in does not work so...
            2a. I rolled back to 6.15-bela1, and... realtime audio-in WORKS (yes!) - in this version, and also...
            2b. To my surprise, multiple MIDI inputs WORK with this older version (?)

          with the following command line in the csOptions:

          -Mhw:1,0,0 -Ma --daemon ; -dm0

          The console still reports a lot of dropouts and a lot of ModeSwitch changes, but not as many as in 6.15 v2

          csounder Are these the messages that you would expect to appear in my terminal when updating?

          no. Something was broken in the package. I uploaded another bela4 version that fixes that.

          csounder
          to test if the soundin opcode is working, you need to add your own mono sample to the project and uncomment
          the ain line with the soundin opcode.

          ;ain soundin "sp_hellorcb.aif" ; Does NOT work on Bela.

          OK, I can reproduce that this doesn't work. In the source code of soundin I see a comment that says soundin now uses diskin2 VL 24-12-16. Not sure if that means anything to you?

            giuliomoro the comment in the code is by Victor Lazzarini - it would be great if you contacted him about this (on the Bela at least) bug. It does confirm that the console is reporting this fact (feature? bug?) when the .csd is loaded and it reports that diskin2 has loaded the sample "sp_hellorcb.aif" - when the soundin opcode is used in the .csd file - but, then... there is silence, no sound, as if the file is loaded and there is no 'error' but the rest of the instrument can't find it. curious. I am sure Victor will have a suggestion and an explanation.

            giuliomoro testing 615-bela5 now.

            Awesome.

            All seems to be working very very well. THANKS!

            (I will report on the Trills in the next post - my Trill Craft is soldered and ready, but that test will wait until tomorrow)

            Here are some details (30 or so models tested - NoteList, Generative, MIDI, Audio Processing, MIDI with Audio)

            Warnings in the console about missing libraries - gone! - check
            Audio IN - check
            MIDI IN - check
            - even Multiple Simultaneous MIDI controllers plugged into a USB HUB (are powered and working) - check
            (when using the: -Ma command line flag)
            MIDI and Audio at the same time - check (controlling Audio FX from MIDI sliders and knobs)

            now, in some MIDI instruments, there do still seem to be an ever-increasing number of mode switching in the audio thread happening, especially when I am using real-time MIDI in, and even more when I have Multiple MIDI in set (-Ma), or without -Ma, but when I am playing lots of notes from my controller keyboard.

            ? do I need to "uninstall" portMIDI ?

            - if so, how do I do this

            Finally, for now, as you know, the soundin opcode is still not working correctly,
            - maybe it will not work on the Bela?
            - maybe this is by design and is related to memory issues and buffering issues?

            BUT WOW - this is a really wonderful update. THANKS.
            - I will be making you some model instruments (for testing and sharing)

              csounder now, in some MIDI instruments, there do still seem to be an ever-increasing number of mode switching in the audio thread happening, especially when I am using real-time MIDI in, and even more when I have Multiple MIDI in set (-Ma), or without -Ma, but when I am playing lots of notes from my controller keyboard

              Please send me the very code that shows this issue.

              To uninstall portmidi try

              dpkg -r libportmidi0

                giuliomoro

                doing some sound design with this MIDI instrument with reverb - quite a lot of mode switching still - and some crickets too. Try it out. You might need to change your CC numbers. I am using the Novation LaunchKey mini and it is set up for controllers 21 - 28 by default

                giuliomoro for comparison, you might be interested in the fact that this instrument, that uses more CPU but does not have any reverb running, does not report and mode switching or dropped blocks

                giuliomoro I have not yet tested the Trill Craft, but this .csd is running the other 4 Trill Sensors in a Trill Hub and sensing Vertical from each and using it to control the pitches of 4 oscillators. You might want to try it out.
                - more to come, and more musical too!

                You need to enclose the code you paste with ``` (triple backticks)

                OK. I will try that now. Sorry for the clutter and confusion:
