ChucK Chat
by Les Hall 23 May '11

23 May '11

Hi everyone, I have a cool idea. Tonight I'm going to start on a ChucK Chat application. This will be a serverless application, so client only. Each program has a list of ip addresses of your pals in it. As you type, it sends out OSC messages that deliver the text to all of the pal clients. The program also displays everything received. The idea is to chat and also jam musically (add music later) - I just thought it would be cool to do a ChucK chat session program! :) Does anyone have any comments or suggestions regarding this concept? I'm coding it now, so please reply soon! Les

Today's ChucKchat NetLooping Session
by Les Hall 20 May '11

20 May '11

For about two or three hours today, I did netlooping on radio.electro-music.com using ChucKchat. The results were quite positive. I announced it on facebook where many music friends hang out, and we got 10 listeners - half from electro-music chat regulars and half from facebook. That's just about how many we get for scheduled shows so it indicates at least some level of interest. I did vocals and music into the loop and explained lots of things about how it all works, plus joked around with the folks in chat. Then near the end, Blue_Hell installed his setup and remotely controlled my software from across the Atlantic ocean! He successfully did things like change tempo and gain and such, but quickly lost interest because, let's face it, a three-word command line interface is not very musically intuitive. So my next goal is to make it more fun by using the mouse and/or keyboard to control the music remotely. That should help a lot in terms of fun. Overall it was a big success for an impromptu event and we hope to have many more events like this. Yay \o/ Les

altering a sample while it reads
by Timothy Leonido 19 May '11

19 May '11

hey all, Is there a way to control aspects of a sample (rate, reverb, delay) while it is being read? I'm interested in, say, playing a minute-long speech sample and being able to change the effects as it is playing. I've done this with supercollider and pure data but can't seem to find the resources in chuck. Thanks! all best, Tim

Internet Jam Suggestion
by Les Hall 19 May '11

19 May '11

I'd like to address the topic of delay and synchronization during internet jams. I feel that the very approach of trying to accomplish audio synch in the current medium of audio over the internet is somewhat inappropriate. In a way it's kind of like trying to get flute sounds out of a guitar. Maybe it's possible, but it's really not in the nature of the beast. To be sure there will come a day when the lag monster is largely defeated and we can jam with simultaneous artists, but that day is not today. I remember the frustration expressed by my fellow grad students whose simulators kept their workstations or even supercomputer accounts busy for long periods of time. I had no such problems as I had chosen to restrict my simulation constraints such that compute times were short. Looking back, this was appropriate as I was matching what I wanted to accomplish to what I had as a resource. In a similar way, perhaps we should not be attempting to defeat the lag monster, but rather to create novel musical jamming techniques that operate within the timing constraints of the web. Now, that's easy for me to say and do because via the power of ChucK and my amateur musician status I can do just about whatever I want, and others may not have that luxury for various reasons. So please accept my apologies if you are limited in this way creatively beyond your control, however I do maintain that we should be doing what we can do, not what we want to do. Back when I constrained my simulator complexity within the available compute constraints, I suffered the consequences of riling up anger and derision from those without that freedom or that choice. I hope that will not be the case with this message. Rather, I wonder if we can discuss ways to create music that fits the web rather than discuss programming that accomplishes synchronization over a web that denies it. I welcome your comments on this topic and I apologize in advance if I have offended anyone. Just my two cents, eh? Les

ChucKchat8
by Les Hall 17 May '11

17 May '11

We tested ChucKchat last night and found some major improvements, a polite way of saying that the prototype was pretty crude so my apologies if you tried it and found it lacking. Anyway, all those bugs are fixed, especially with the use of line reading which forces us to use the command line version of ChucK only but that's OK. We did manage to test features like turning each other's music on and off from across the web and that worked just fine. Several details like text feedback of each feature, etc, were added. I also put the ip addresses in a "friends.txt" file external to the source code so I can distribute the code without revealing my friends' ip addresses to the world, nice feature lol. At radio.electro-music.com I have started some discussion about having a ChucKchat net-looping concert which should be fun, and in the mean time I am doing some individual net-looping of my own. Oh, and ChucKchat now has a properly working and debugged Karplus Strong algorithm driven by a thing of my own creation, a Boolean Sequencer. Just keeping you all updated. Hmm, no response from the group yet... Les

ChucKchat 6
by Les Hall 16 May '11

16 May '11

OK, i'm up to version 6 of ChucKchat and it's got a manual too. I put in a full boolean sequencer and Karplus Strong algorihm, both controllable via remote or local commands. Plus there's a crude chat interface, what a freaky way to use ChucK's capabilities! It's posted on the electro-music.com ChucK forum, enjoy! Les

Novation Launchpad examples
by Jordan Orelli 15 May '11

15 May '11

I wrote some code for the Novation Launchpad a while back, and I was taking a look at it recently and (of course) couldn't figure out how it worked, so I wanted to start over. I separated the interaction with the Novation Launchpad into a side project so that I could just grab it whenever. Here it is, for reference, if anyone wants to copy it. The examples are all stupidly simple; the useful part is that the MIDI messages are already parsed into grid coordinates; that was the part I kept wanting to import ^_^ https://github.com/jordanorelli/Launchpad-Examples -Jordan

How To convert integer number to float number on max msp
by Tony Maryana 15 May '11

HI, Every one Would you give me solution for my problem about converting integer number to float number. this is sample my script ,this work on mini audicle but still error on chuck objek on max msp. Thanks alot for your help ///////////////////////////////////////////// while (true) { Std.rand2(24 , 35) => int asoy; // integer number to be converted asoy $ float => float asik; //convert int to float ( asik => m.floatout// send data information to outlet chuck object on max msp 0.7::second => now; count + 2.0 => count; } ///////////////////////////////////////////////
