Hi, I've been making a few Chuck synths lately and have been wanting a way to play them straight from the keyboard instead of having to attach a MIDI device. I used to do this all the time with FastTracker back in the DOS-ages. Anyways, of course Chuck can get keyboard input, so all that was missing was a mapping from the keyboard keys to MIDI note numbers. Attached is a Chuck script that reads the keyboard and then generates Events containing a note number. These are available through a public class, so a separate Chuck script can wait for the events and spork notes. Note that it's not quite an up-to-scratch implementation of polyphony, since there is only a single event structure that will get overwritten by the next key press. Maybe I'll work on that next... (perhaps using an array to store extra notes, but some timing calculations will need to be made..) Oh yes, and this is designed for a US keyboard, but feel free to change the keymap. I figured it out from the kb.ck output. So anyways, enjoy. :) ps., run concurrently: $ chuck kbpiano.ck kbpiano_example.ck Steve

Recommended books?
by Carl-Gustaf Harroch 05 Aug '07

Chuckist, Are there any books that you recommend for general computerized music? If I want, for instance, to get involved in the development of chuck, which book would you recommend? Especially about general notions such as oscilators. music theory, tempo, sampling etc... I am quite new to all of this but would really love to get into the core of music programming. I have been through the chuck manuals but it is stil quite high level and would like to understand the basis of the language itself. Any help much appreciated. ./Carl

rec.ck gives an error and rec-auto.ck becomes mono

came up with the idea to turn my podcast http://www002.upp.so-net.ne.jp/buyobuyo/micro/rss.xml "chuck is in dub"(learning chuck} oriented did chuck isthisokay.ck maybe.ck rec.ck and it became [rec.ck]:line(7): class 'Shred' has no member 'getArg' chuck isthisokay.ck maybe.ck rec-auto.ck is okay but mono(might be as-is) is there a better example that i write stereo .wav to my hdd? i also wonder where i do 1 => w.record; 0 => w.record; oh! in the .ck file? this is what i have as isthisokay.ck and maybe.ck is something similar SinOsc s1 => Gain g1 => dac; SinOsc s2 => g1; SinOsc s3 => PRCRev g3 => dac.left; SinOsc s4 => PRCRev g4 => dac.right; .25 => g1.gain; .25 => g3.gain; .25 => g4.gain; while( true ) { Std.rand2(32, 64) * 55.0 / 32.0 => s1.freq; 5322::ms => now; s1.freq() * Std.rand2(8, 16) / 4.0 => s2.freq; s2.freq() * Std.rand2(16, 32) / 16.0 => s3.freq; s2.freq() * Std.rand2(16, 32) / 16.0 => s4.freq; 222::ms => now; } -- 2g http://micro.ispretty.com

Hardware information?
by Carl-Gustaf Harroch 03 Aug '07

03 Aug '07

Chuckists! First mail in this mailing list and there will probably be many more. I am a newbie with chuck. Been reading a bit and I am very excited to get my brain into this. Thanks all for putting this public. This looks exactly the type of language I ve been looking for in the last couple of months. I come from the programming side rather then musical. Anyway, my question relates to hardware. I am using ubuntu or gentoo OS. Do you have any hardware recommendation for a sound card? My current inboard card flickers the sound when I launch a simple sin loop. Even without any sound, I can hear some noises - I just think my current card is really really bad. Do you have any suggestions for a good sound card? What is the best solution - get an amplifier and use a numeric2analog converter? Secondly, I guess ALSA is the way to go or JACK, any documentation on that? Thanks, ./.Carl

can there be many ::ms in while?
by 2g 03 Aug '07

03 Aug '07

have just started coding on chuck was looking for way to let s1 have 3 overtones flying around him i know it should be something other than rand2f to handle integers but my q is about ::ms in while i wonder which one of these are the right way to use them i thought the latter might be safe but it seems to give one never changing long note and maybe only one another is floating around but none of them give me an error style one: SinOsc s1 => PRCRev g => dac; SinOsc s2 => g; SinOsc s3 => g; SinOsc s4 => g; .25 => g.gain => g.mix; while( true ) { 500::ms => now; Std.rand2f(30.0, 220.0) => s1.freq; 170::ms => now; s1.freq() * Std.rand2f(8.0, 16.0) / 8.0 => s2.freq; 75::ms => now; s2.freq() * Std.rand2f(16.0, 32.0) / 16.0 => s3.freq; 111::ms => now; s2.freq() * Std.rand2f(16.0, 32.0) / 16.0 => s4.freq; } style two: SinOsc s1 => PRCRev g => dac; SinOsc s2 => g; SinOsc s3 => g; SinOsc s4 => g; .25 => g.gain => g.mix; while( true ) { 200::ms => now; Std.rand2f(30.0, 220.0) => s1.freq; } while( true ) { 170::ms => now; s1.freq() * Std.rand2f(8, 16) / 4.0 => s2.freq; } while( true ) { 75::ms => now; s2.freq() * Std.rand2f(16, 32) / 8.0 => s3.freq; } while( true ) { 111::ms => now; s2.freq() * Std.rand2f(16, 32) / 8.0 => s4.freq; } -- 2g http://micro.ispretty.com

About joysticks
by Martin Ahnelöv 31 Jul '07

31 Jul '07

Hello. I feel that I would like to fiddle around a bit with Hid-devices. More precisely those who look like modern console-controllers like Xbox 360's, Playstation 2/3, and Xbox 1's small controller. Is there any gotchas I should know about when both choosing and using these (I have understood that the rumble-feature isn't implemented)? Also, I went to the computer-store today to look for a joystick, but I could only find these third-party ps2/3-controllers. I did find a ps2 to usb-converter, but since I were unsire I though that I should ask here for your experience first. You think it would work? Anyways. I hope I find something more X-box-like, since I'm not too fond of Playstation. Gasten

Hello and a cool snippet (crash)
by Martin Ahnelöv 22 Jul '07

22 Jul '07

Hello there! I've been playing a little with ChucK for the past few days and I'm really enjoying it. After finally figuring out how to modulate a sinosc's frequency (that one really needs documentation!), I though I were ready for som Hid action. It were actually much easier to set it up than I thought - but still a bit harder than I would like (probably due to the lack of documentation). Well, I successfully miss-used the program and got a couple of different crashes (woo!). I think the following is cool. // Patch SinOsc s => Gain g => dac; SinOsc lfo => blackhole; 1.0 => lfo.freq; 300 => lfo.gain; 0.4 => g.gain; // which mouse 0 => int device; // hid objects Hid hi; HidMsg msg; // try if( !hi.openMouse( device ) ) me.exit(); <<< "mouse '",hi.name(), "' ready...", "" >>>; while(true) { hi => now; while(hi.recv(msg)&&msg.isMouseMotion()) { lfo.last() * (msg.deltaX-msg.deltaY) => s.freq; //rubbie! } } Try changing the msg.deltaX-msg.deltaY to msg.deltaX*msg.deltaY or msg.deltaX/msg.deltaY for the crashes. Bug? This might be Linux-specific. By the way, isn't msg.deltaX and Y pretty inconsistent from the rest of the API? shouldn't it be msg.deltaX()? Well, Thanks for a great tool!

Re: [chuck-users] chuck-users Digest, Vol 24, Issue 5

Hi. I'd like to request for a feature. I'd like to be able to read a list of UGens that is chucked from a UGen. Or a list of UGens chucked into a UGen also. That'd be quite useful for programs with dynamic chucking. For example, for checking the order or wether two UGens are connected or not. Thank you ^_^. - kijjaz
