Awesome, I am testing now. It eliminates a lot of warning messages. (wonderful)
1. You might need to add a ksmps = 16 or ksmps = 8 to your 0-hello.world example.
2. You suggest that one needs to install the latest portMIDI (libportmidi0_217-6_armhf.deb) too.
(this might also be a requirement, to get your 4-MIDI-in example to run too.)
- I know how to install into individual projects, but I am wondering how to install/update for all projects
(searching the forum now for advice on this)

    csounder 1. You might need to add a ksmps = 16 or ksmps = 8 to your 0-hello.world example.

    Will do yes. Haven't touched the examples yet, actually I meant to ask you if you wanted to provide some that would work out of the box, to improve and enrich our currently scarce portfolio.

    csounder - I know how to install into individual projects, but I am wondering how to install/update for all projects
    (searching the forum now for advice on this)

    The method I previously explained (drag on the IDE, and run in the console dpkg -i PROJECTNAME/*.deb actually installs the package globally.

      There might be an issue with audio in.
      - an instrument that previously worked with real-time audio input (coming from a mic in a mixer, for example),
      does not seem to be working now with Csound 6.15 V2

      • I have tried setting it with the -iadc commandline input flag (previously not necessary), and it still does not work.
        I will attach several .csd files for you to use in your tests.

        wow! who knows what I did there

        csounder I will attach several .csd files for you to use in your tests.

        thanks, looking forward to this

        giuliomoro Thanks! I have been doing this, and in the console, it does report that things are being unzipped, but then the previously working MIDI instruments are not working now. WAIT! I think I have it...

        In the past, (probably because it was using other MIDI drivers?), in the command-line, it was recommended that one set the following defaults:

        -Mhw:1,0,0 -+rtmidi=NULL --daemon -dm0

        it turns out that you do NOT want to set -+rtmidi=NULL any longer

        Once that is removed, all my previously running MIDI instruments are working AND...

        I am very happy to report that you are now supporting the connecting of multiple MIDI devices
        - I have a USB hub plugged into the Bela MINI
        - I have a Novation LaunchPad mini Mk3 PLUS a Korg NanoKontrol plugged into the hub
        - I am running my MIDI .csd with the following command-line arguments

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

        And both controllers are playing and controlling the instrument! (WONDERFUL)

        • You might need to make changes to the Csound examples, as I suggested to you previously
          using this as a default header for the .csd files

        sr = 44100
        ksmps = 16
        nchnls = 2
        0dbfs = 1

        and for MIDI instruments:

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

        Now to get to the bottom of why the audio input is not working on previous .csd files.
        - any suggestions about what might have changed, or what might now be required.

          csounder You might need to make changes to the Csound examples, as I suggested to you previously

          will do once the release is ready.

          csounder - any suggestions about what might have changed, or what might now be required.

          nothing as far as I know 🙁 send me an example passthrough patch and I can have a look

          When I comment out the RtMIDI=NULL from the 4-MIDI example, it runs, but...

          there are a lot of little clicks now (possibly data-lates as Barry Vercoe used to call them?)

          and the console does report a lot of dropouts and mode switches (which might explain the clicks)

          I am using the following sample rate and krate settings

          sr = 44100
          ksmps = 8. or ksmps = 16
          nchnls = 2
          0dbfs = 1

          I see. Mode switches are happening.

          Was this not happening in the script you previously mentioned was working fine? If that's the case, could you send me the well behaving script?

            giuliomoro There were almost always "some" mode switches and dropped blocks, but never this many and never these little cricket clicks. I will send you a few files to test. Working on them now.

            sounds like this is not a viable solution then, and I may have to revert to the previous one. Can you send me some example code that uses multiple MIDI devices? Then I can figure out how to make it work with the "Bela" MIDI API.

              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.

                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.

                      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.
