[PD] Re: stuck installing on OSX

[Mitchell Turner]

Alex,
I went back and re-read the entire thread.  It explained it all.  I 
have followed your instructions except the last items.

I opened terminal and tried to "cd" over to the new "/pd/usr/" 
directory. I receive the response:
No such file or directory.
Did you mean pd/src/? There is a "configure" in there. I assumed that 
you meant pd/src/ so, I ran the ./configure and make from pd/src/.

I still must supply command line flags to get it to work with my 
Fastlane 2X2 (USB MIDI).

So, I typed the following at the command line:
% ./pd -midiindev 0,1 -midioutdev 2,3
using default input device number: 0
using default output device number: 2
nchan 2, flags 3, bufs 8, framesperbuf 256
PortAudio on OS X - Latency = 2048 frames, 46 msec

I can now send and receive MIDI from either port of my Fastlane.  MIDI 
channels 1-16 come from portA and MIDI channels 17-33 come from portB.  
Just like it should.

On the audio front.  If I use the Built-in Audio controller, everything 
is fine.  If, however, I try to use my Mbox things do not go well.  It 
appears to only have 1 in and 1 out

./pd -listdev
Number of devices = 4
---------------------------------------------- #1 DefaultInput
Name         = Built-in audio controller
Max Inputs   = 2, Max Outputs = 0
Sample Rates = 44100.00,
Native Sample Formats = paFloat32,
---------------------------------------------- #2
Name         = Digidesign HW ( MBox )
Max Inputs   = 1, Max Outputs = 0
Sample Rates = 44100.00, 48000.00,
Native Sample Formats = paFloat32,
---------------------------------------------- #3 DefaultOutput
Name         = Built-in audio controller
Max Inputs   = 0, Max Outputs = 2
Sample Rates = 44100.00,
Native Sample Formats = paFloat32,
---------------------------------------------- #4
Name         = Digidesign HW ( MBox )
Max Inputs   = 0, Max Outputs = 1
Sample Rates = 44100.00, 48000.00,
Native Sample Formats = paFloat32,
----------------------------------------------

When I try to tell pd that it has 2 channels, like this:
% ./pd -inchannels 2 -outchannels 2 -audioindev 2 -audiooutdev 4 -nomidi
nchan 2, flags 3, bufs 8, framesperbuf 256
PortAudio on OS X - Latency = 2048 frames, 46 msec
Error number -9999 occured opening portaudio stream
Error message: Invalid number of channels.

I am unsure of the meaning of the error message Error number -9999

If I lie to pd and tell  it that the Mbox has only one channel:
% ./pd -inchannels 1 -outchannels 1 -audioindev 2 -audiooutdev 4 -nomidi
nchan 1, flags 3, bufs 8, framesperbuf 256
PortAudio on OS X - Latency = 2048 frames, 46 msec

I can send and receive audio on one channel in and out.  I wonder if 
this is a problem with the Mbox's coreaudio driver.


Thanks again Alex, I really appreciate your helping me with this.
Mitch
