MIDI-synchronization and metric timing (?)
by Blixa Barscheck 05 Dec '13

05 Dec '13

Hi, ChucK-Community! My name is Steve. So far I have been using Max 6 for MIDI-programming. My primary workflow is that I generate MIDI-data in Max and send them to my DAW where it's used to trigger several SoftSynths. I am the point now, however, where Max doesn't offer me enough flexibility to realize what I want to do. I am considering switching to ChucK. There is one thing, however, I need to know about ChucK: In Max I am able to synchronize it's timing mechanism to my DAW and define any kind of timing data (e.g.: frequency of an LFOsc) in metric timing (1/16-notes, 1/8-notes, etc.). Is this also possible in ChucK? If no, then ChucK unfortunately is no option for me, at least at the moment. Thanks! best regards, steve -- Diese E-Mail wurde aus dem Sicherheitsverbund E-Mail made in Germany versendet: http://www.gmx.net/e-mail-made-in-germany

I have installed the beta version of ChucK and miniAudicle whick supports PulseAudio in Linux. I am now able to view a course video and use ChucK at the same time. Thanks to all who helped me on this. Monon

What does $ do?
by Gregorio Gomez 22 Nov '13

22 Nov '13

Hello, everybody: I've been looking at Michael Heuer's (most excellent) LiCK library. He uses an idiom that I don't see documented: intervals.get(i) $ Interval @=> Interval interval; from Arpeggiator.ck, line 35 https://github.com/heuermh/lick/blob/master/Arpeggiator.ck What does $ do? Of course just because I don't see it in the documentation doesn't mean it's not there, so please feel free to point me to the docs if I've overlooked it. Thanks! Greg

Problem with multiple audion sources
by monon＠att.net 20 Nov '13

20 Nov '13

I am a new chuck user and have just installed linux-alsa from source. All works well as long as there is no other audio source active. If there is another active audio source active I get this message when, for example, I type in chuck --loop: [chuck]: RtApiAlsa::getDeviceInfo: snd_pcm_open error for device (hw:0,0), Device or resource busy. This seems to be a chuck issue as I can run multiple audio sources as long as one of them is not chuck. My concern is that I started a coursera course on chuck and would like to use chuck concurrently with the course. My operating system is Kubuntu Linux 12.04. Does anyone have any ideas? Thank you, Monon

chuck + PulseAudio (was: Problem with multiple audion sources)
by Spencer Salazar 14 Nov '13

Hello ChucK linux users, We are excited to have a beta version of chuck that features PulseAudio support! While PulseAudio is not always ideal for professional audio usage, we absolutely recognize that its a popular choice for general-purpose Linux installations. We would love it if Linux + Pulse users could try out the beta and report any feedback, issues, etc. ChucK source (version 1.3.3.0-beta-3): http://chuck.stanford.edu/release/files/beta/chuck-1.3.3.0-beta-3.tgz miniAudicle source (version 1.3.1-beta-3): http://chuck.stanford.edu/release/files/beta/miniAudicle-1.3.1-beta-3.tgz Thanks, spencer On Wed, Nov 6, 2013 at 1:12 AM, Harald <hg42(a)gmx.net> wrote: > pulseaudio should usually work out of the box because most linux desktop > distributions have this installed and configured, so it should be nice for > beginners. > > But musicians etc. / linux music distributions usually use jackd. > > Apart from that alsa allows to create virtual devices to be routed through > pulse or jack for those who know how to do it. > So alsa would be a good choice for all, but unfortunately desktop > distributions don't come with alsa on top of pulse (from what I remember). > > So there should be a choice between all these systems, probably with > default to pulse and a BIG comment at a prominent place saying latency etc. > may be bad and using jackd would be better.

[MiniAudicle] Minor bug with editor
by Pierre Faure 11 Nov '13

11 Nov '13

Hi, I recently acquired a late 2013 Mac Book Pro running Mavericks. While working on MiniAudicle on this computer, I noticed a few problems, all bypassable, but annoying nonetheless. First of, while using non ascii characters, like ‘é’ in strings. I made a program that looks up samples, and their name is hardcoded in the script, e.g. « réso1.wav ». When I save the file for later use, and load it up again, the ‘é’ are gone, the editor displays « reso1.wav ». My files are therefore not accessed. I don’t think that is normal, as on my Windows PC, non ascii characters are accepted. Secondly, when I paste from the terminal (like a folder path), the editor uses whatever colors my terminal background is set in. I use black, so when I paste, the background of the pasted line becomes black. Lastly, here’s an error message I get from the console window. 2013-11-11 18:14:31.318 miniAudicle[662:707] *** WARNING: -[NSImage dissolveToPoint:fraction:] is deprecated in MacOSX 10.8 and later. Please use -[NSImage drawAtPoint:fromRect:operation:fraction:] instead. 2013-11-11 18:14:31.318 miniAudicle[662:707] *** WARNING: -[NSImage dissolveToPoint:fromRect:fraction:] is deprecated in MacOSX 10.8 and later. Please use -[NSImage drawAtPoint:fromRect:operation:fraction:] instead. Again, those are minor problems. Best regards, Pierre FAURE
