Reply with quote  Mark this post and the followings unread

Have nasty problems trying to run miniAudicle and/or Chuck on OS X Lion.

Just installed mA and Chuck on a MBP 13" running current version of Lion. I installed Chuck first, ran the simple check and it returned the appropriate message:

demos@DREIZEHN% chuck
[chuck]: no input files... (try --help)

...but here's the Console output from mA when I start the Virtual Machine (just before I get the pop-up warning that the Virtual Machine appears to be hanging —

[chuck]: (via rtaudio): one or both 'channel' parameters must be greater than zero.
[chuck]: cannot initialize audio device (try using --silent/-s)


...not sure how to troubleshoot it from this point.

Best,

~~D.

Code:
[chuck]: (via rtaudio): no devices found for given stream parameters:
... RtApiCore: No supported sample rates found for OS-X device (Apple Inc.: Built-in Output).
... RtApiCore: No supported sample rates found for OS-X device (Apple Inc.: Built-in Input).

[chuck]: cannot initialize audio device (try using --silent/-s)


I am also having problems running the precompiled ChucK binary under OSX Lion. I don't see any output on the console, just above error when I execute the first (sine-wave generating) program of the tutorial.

I'm going to try building from source. fingers crossed...

Compiled from source. Exactly the same output.

It seems that something may be hardwired to a previous OSX audio architecture. Maybe some changes can be made to the makefile? Or is it possible to try to connect to a specific audio interface in the code?

I'm not holding out much hope of assistance here, but may as well document my progress (or lack of!).

PostPosted: Sun Oct 30, 2011 9:36 pm    Post subject: audio working in lion... so far no midiout Reply with quote  Mark this post and the followings unread

I've been looking for a way to get chuck to pass user input back out as midi and I ran into this forum, which proved quite useful. I am also running MA on a 13" MBP (most recent) with Lion. I found a beta release of chuck and MA on the mailing list that got me audio support, at least so far. Here's the link:

https://lists.cs.princeton.edu/pipermail/chuck-users/2011-August/006329.html

There are two downloads there, obviously for Chuck and MA.

I don't know if my midi issues are related to Lion or my audio/midi setup, but I am so far unable to open a midi port to send midi out. Just using the standard midiout example from the documentation (pdf, no midiout examples on the website).

As I suggested, it was my audio midi setup that was causing the issue. I still get a "hanging" notice when I run this:
Code:

MidiOut mout;
MidiMsg msg;

// check if port is open
if (!mout.open(0))
   me.exit();

// fill the message with data

144 => msg.data1;
112 => msg.data2;   // note
while(true)
{
   127 => msg.data3;   // velocity
   mout.send(msg);
   125::ms => now;
   0 => msg.data3;
   mout.send(msg);
   125::ms => now;
}


but I just hit cancel, brought up midi monitor and the note signals were chugging away.

So it looks like if you download those files, everything should work for you.
