Scale & diatonic
by Hans Aberg 12 Oct '11

12 Oct '11

I have made a program, scale.ck, that admits one to work with scales, including tuning stretch, céleste tremulant, retune them, and then save to a file, with a line of code that can be pasted back into the source, available at next program startup. Scale tunings can be put into tuning banks, and otherwise defined by your favorite method. Details in the file. I have also updated my program for diatonic tuning systems, diatonic.ck. Just a few changes: adding some common tunings, fixing typos. The files are available here: http://www.math.su.se/~haberg/tuning_systems/ Hans

I think this error has been documented here before; the problem is in line 24, the for loop.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 right. while running through the directories in examples, what i would do is pull up the ck file on screen, try and figure out what it was trying to do and what it would sound like in my head, then i wouldn't change a thing, and execute the chuck command on that file, and see if i was right. an amusing way to learn chuck coding perhaps, though it seems to work for me. anyway, this deals with the file in the deep subdir called unclap.ck, that seems to give me a 'program has caused an error' dialog box, and options to submit the error or not. in other words, file not run. and the most amusing part is i can't even guess why this might be. i can say that i'm using the windows version of chuck.exe, 1.2.1.3 i think it is. and can't think of anything else to put in here. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBAgAGBQJONPeuAAoJEIaKvi7tbzRH80gH/2kEF19jw7yqCq6SDefcS7Sa D/J3bwHi5fsMBJMI/k84ZWS7wmYy2STXLFXBomM0YHUbsQVlouzhS8ocV+Dul6u/ mkcYLqFlw0c6jTIRsr2S3HqLvdMtQQsvDEg5UjQ5PfpQulVh7BputHvDTAG7WkGq rREyCGdRsjmccmYwJyCJ1zxkgNyCT+8wYqJ2EH8uzBSBo6SaiTxgdKle3RM1Du/h 2ubzu/7yWdrzltpn0j084UX2DGra460Frcx90OcgvzB3n40VtcD5B1PahFW5stYD nCFL/Rsq3+G90C+EOTmJeSrOBVfsZS/CFLWljsIMp5BzeqTuJJ73OcWaPW6SUck= =/Skd -----END PGP SIGNATURE-----

MIDI Forwarding?
by Johnathan Bell 26 Jul '11

26 Jul '11

All, I was looking at Ableton to do this, but I think I may be able to achieve a cheaper and better solution using ChucK ... I want to forward MIDI messages from a USB-MIDI keyboard, through a computer, to a hardware synth that has the standard MIDI in/out ports. My keyboard does MIDI over USB, but has no standard MIDI ports, so I can't plug it directly into a synth, but if I were to use a USB MIDI interface on my computer, could I interface the keyboard to the synth that way, using ChucK as a go-between? It'd be a simple matter of opening the MIDI in from the keyboard, and then just copying those messages to the MIDI out of the interface, I'm thinking... - Johnathan

chuck on os x 10.7 (lion)
by Jonas Zeleninsky 24 Jul '11

24 Jul '11

Hello, my first post here, so please excuse me if I'm doing something wrong. I installed the latest version of chuck on my 10.7 system, and I am facing this issue: go-vegan:basic Jonas$ chuck demo0.ck [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). My sample rate is 44100, and I didn't change it since the Snow Leopard (where ChucK worked without any problem). Anyone else having this problem? Or can think of solution? Regards, Jonas

irc channel
by Jonas Zeleninsky 24 Jul '11

24 Jul '11

Hello, currently trying to analyze the digiio_rtaudio.cpp and I came to idea, that would be nice to have IRC channel where we can discuss issues more directly/hangout, deal with non-dev issues as well. is there one maybe? If not, I made one at irc.freenode.net called #chuck. See you there! Regards, Jonas

I mean, I imagine that downloading and compiling the new version of rtaudio isn't enough, the link with ChucK would be missing. It looked as though the old RTaudio files in ChucK should be replaced by the new one; then recompile. That is, Chuck does not call RTaudio library but uses the sources. But if that proves complicated, it should be possible to install RTAudio as a library, take away the old sources from 'chuck', and the make sure the rtaudio library is included when linking (say by tweaking the chuck Makefile). That does not result in a standalone binary, though., but you will know if it fixes the problem. Hans
