I have a new build now that takes care of some of these things. You have to specify the ksmps, and ensure that the Bela blocksize (in the IDE) is a multiple of it. (they can also be the same).
It should also fix multi-input-device MIDI (as long as you install the portmidi package)
See here https://github.com/giuliomoro/csound/releases/tag/6.15-bela2
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

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)
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
using this as a default header for the .csd files
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:
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)

</CsoundSynthesizer>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.
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.
