Trying to get start with Chuck on MAC - USING TERMINAL
by gary hiebner 27 Jun '09

Hi Everyone, I am new to Chuck. I saw Ge's video on the Apple website and am very interested in getting into Chuck as an audio tool for live performance. I seem to be having a problem getting it to run. I have tried going through the start up manual as it says, but keep getting the same error. I have added chuck to my usr/bin/ When I check through the /usr/bin I can see chuck there, so it has been added successfully. Then I type the >chuck in Terminal I don't get the [chuck]: no input files.... message i tried typing the command: > chuck // connect sine oscillator to D/A convertor (sound card) But just get the following error message: -bash: syntax error near unexpected token `(' Is there something else I am not doing correctly? I have tried in miniAudicle, and everything works fine there, But would like to get this working from the Terminal. Thanks in advance for any assistance, Regards, -- Gary Hiebner SoundBase Productions cell: 082 877 6239 www.soundbase.co.za This message contains privileged and confidential information intended only for the person or legal entity to which it is addressed.

Thanks Rob! Silly me, I'd read the manual but didn't realize how exactly it works. Now it is more clear. Atte: Nice trick, thanks! It's a bit "aesthetically ugly" to do it this way, especially for more arguments, but it should the job.

crashing VM on (<string> != null) test?
by Robert Poor 24 Jun '09

24 Jun '09

I'm so baffled that this must be easy. What is the proper test to see if a string is null? More to the point, why does the following code bomb out on the conditional test? "foo.txt" => string g; <<< g >>>; // prints '"foo.txt" : (string)' if (g != null) { // evidently crashes here with "[chuck](VM) NullPointerException (during string op)..." <<< "not null" >>>; } else { <<< "is null" >>>; }

a couple of questions
by Bozelos Dimitris 22 Jun '09

22 Jun '09

Hello everyone! 1) can default values be passed to a function? I've tried all of fun void test( int i = 0) fun void test( 0 => int i) fun void test( int i => 0) but nothing works and in the manual nothing is stated. Anybody knows? I would be surprised if you cannot pass default values to a function. Why if so? 2) by printing <<< now >>>; I get the timestamp from the virtual machine, but if I do <<<now>>>; /// do some stuff <<<now>>>; the two outputs are exactly the same even if the stuff in between last for some seconds. Why? How can I know the duration of something? Cheers, Dimitris ___________________________________________________________ Χρησιμοποιείτε Yahoo!; Βαρεθήκατε τα ενοχλητικά μηνύματα (spam); Το Yahoo!

Solved: getting simplest mrmr => iPhone => OSC => ChucK app to work
by Robert Poor 21 Jun '09

21 Jun '09

Solved my own problem: I had accidentally left the OSC-Client running, which was evidently snarfing all my OSC events and preventing ChucK from receiving them. Killing OSC-Client made everything work. - Rob On Sat, Jun 20, 2009 at 21:38, Robert Poor <rdpoor(a)gmail.com> wrote: > I've installed mrmr on my iPhone.

getting simplest mrmr => iPhone => OSC => ChucK app to work
by Robert Poor 21 Jun '09

21 Jun '09

I've installed mrmr on my iPhone. I also downloaded and installed Niklas Saers's OSC-Client (http://niklas.saers.com/Media/OSC-Client.zip) on my MacBook Pro. OSC-Client shows that I've configured things correctly; I'm receiving messages such as: messages: /mrmr/accelerometer/direction/2/PoorPhone 2 messages: /mrmr/accelerometer/force/2/PoorPhone 54 messages: /mrmr/accelerometer/angle/3/PoorPhone 134 messages: /mrmr/accelerometer/force/3/PoorPhone 54 ... but haven't been able to get the simplest ChucK program to honor the messages. Here's the code -- it never gets past the "oe => now" call. I'm sure my error is obvious to the old hands out there -- any suggestions? OscRecv orec; 1500 => orec.port; orec.listen(); orec.event("/mrmr/accelerometer/force/3/PoorPhone, i") @=> OscEvent @oe; while (true) { oe => now; while (oe.nextMsg()) { oe.getInt() => int i; <<< "got", i >>>; } }

iPhone => OSC apps
by Robert Poor 20 Jun '09

20 Jun '09

I've been having so much fun with my GameTrak controller in ChucK, I now want to add my iPhone as a controller. It appears that there are numerous iPhone/OSC apps, I'd like people's opinions about which ones work well and which ones don't. Here's my roster: iOSC ($2.99) Mrmr (free) OSCar (free?) OSCemote ($4.99) OSCRemote (free) pOSCa (free) TouchOSC ($4.99) Omissions? Recommendations? FWIW, I'm especially interested in the accelerometer data -- I think they all provide some support for that, but some may be better than others. - Rob

Re: [chuck-users] eChucK Update
by Les Hall 17 Jun '09

Vilson, I'd be happy to send you a board. Also the Eagle CAD design files for it are posted on the eChucK forum Eagle CAD is freeware and cross-platform to Mac, PC, and Linux, so that's why I use it. Well, actually if you use it for profit you have to pay for it, but for us hobbyists it's free. The maximum allowable board size is small but sufficient for many small projects. If you download the files you won't have to reverse engineer the board but I'll send you the last remaining board anyway. It's nothing special, but it will give you the idea of what's going on. Oh, and if you prefer I have one board that's already chopped up into little boards. Please email me (inventor-66(a)comcast.net) with the mailing list and your preference as to which board you would prefer me to send (whole or chopped up). And especially thanks for participating in the project, I'm sure it will be wonderfully educational. Les Mark, Thanks for the encouraging words. I'm beginning to realize that having these first four boards made was primarily an exercise in learning Eagle CAD and working with a board house as a hobbyist, plus more importantly it has provided sort of a focal point for getting the ball rolling on the eChucK project, even if we never use these first boards in practice. It helped make people realize that the project is tangible and real and ever so slowly gaining momentum, etc. The cost at the board house I used was $100 for four boards, 3" x 4" in size. That's double sided with solder mask and screen printing, but not chopped up into little boards. So that works out to about $30 each including shipping. Not cheap, but acceptable I suppose. I hope you enjoy your perusal of the eChucK forum and please feel free to post a message if you like, the more people who chime in, the more excited other people will become. Enjoy. Les

eChucK Update
by Les Hall 17 Jun '09

17 Jun '09

Hello again fellow ChucKists, You may recall a while back that I posted a few times about this interesting eChucK project that I conjured up one day and started developing. There has been some good progress and the project is moving along slowly but steadily. Here are the latest updates: eChucK is inspired by and related to ChucK. The "e" stands for electronic, so it's a hardware implementation of some of ChucK's features in concept. The idea is that we would like to create little bitty postage-stamp sized circuit boards that perform ChucK UGen, code, and instrument features in electronic form and then wire these boards up into free-standing "sculptures" that can create music on their own or interact with ChucK software or both. Also ChucK can model eChucK sculptures, which I have done a few times. One of the things that makes eChucK interesting to people, and perhaps it's most defining feature, is the interconnect method. As you know, modular synthesizers are typically built into panels or other enclosures and interconnected with patch cords or jumper wires. So you have this rigid structure with wires all over it, which is just fine as a way of hooking up the circuits. eChucK, however, is the dual or opposite of that - the yang of the synthesizer yin, in a sense, because the concept is to use solid wire (not stranded) to perform the interconnect in such a way that the strength of the solid wire is sufficient to hold the little boards in a free-standing 3D "sculpture". So there is no enclosure, no panel, etc. This idea is apparently at least somewhat novel as I have received news from various folks who find it interesting. OK, now for the updates. I had four dsPIC-based eChucK circuit boards made and two of them are taken, I'm keeping one for myself, and there remains one board to be mailed out for free to anyone who would like to work on the project. Please let me know if you would like me to send you this board. In other news, the awesome folks at www.electro-music.com were interested enough in eChucK to create a forum for it right next to the ChucK forum under the DIY section. I am moderator of that forum and I posted design files, hardware and software descriptions, and ChucK files there. Some folks have participated in the eChucK forum threads and a few are working on their own vision of what eChucK should eventually become. We have one fellow working on a special type of processor (i forget which) for eChucK in England, I'm working on some Lunetta-based eChucK possibilities, and I just heard from someone in Brazil who is planning to create an Arduino-based eChucK project. I purposely left the specifications of the project as open and unstructured as possible so that people could do things however they wanted as long as everything works together. So things are moving along nicely in the eChucK realm. To date there do not exist any completed projects, but momentum is growing steadily. I really enjoy the occasional email or post about eChucK, especially when someone is excited about the possibilities. Well, anyway, I thought it was time to mention all of this stuff on the ChucK Users list to keep you posted and also to see if anyone has any thoughts about the project. That's all for now. Les (Inventor)
