OSC pattern matching
by dparson 26 Jul '13

26 Jul '13

It's been a while, so apologies in advance if this topic has come up lately. Last time that I wrote an OSC receiver in ChucK, the code had to match the incoming address pattern verbatim. There was no way to apply pattern matching, e.g., a regular expression, to match the incoming string. Also, I don't think that there was a way to match a prefix of the incoming string, after which one could in theory write one's own pattern matcher on the remainder of the incoming string. Little time for that, anyway. Is it (still) necessary to match the incoming OSC pattern string, literally, in its entirety? My solution last time was to spork a separate shred to match each incoming literal string in its entirety. That approach does not fully solve the problem at hand. Thanks. Dale (Acoustic Interloper)

Ah yes, it's not possible at the moment I'm afraid, but since many people have been asking about multi-channel chug ins, it wouldn't surprise me if they include it in the next version.

How can one build stereo chugen
by Rich Caloggero 29 Jun '13

29 Jun '13

It seems from all the documentation I can dig up that the chugen class (i.e. your class subclassed from Chugen) can have a tick method with only one in and one out. How can one make a stereo chugen? Thanx, especially if I’m missing something obvious. -- Rich

Very Basic Question
by Rich Caloggero 26 Jun '13

26 Jun '13

On several ugens, I see both a phase parameter and a phase offset parameter. What exactly do these mean and how would one use them. For instance, on the sndbuff ugen: • .phase - ( float , READ/WRITE ) - set/get phase position ( 0-1 ) • .phaseOffset - ( float , READ/WRITE ) - set/get a phase offset Thanx much... -- Rich

EspGrid 0.42
by David Ogborn 10 Jun '13

10 Jun '13

Dear friends, I am pleased to announce the official release of version 0.42 of the EspGrid software - the synchronization and sharing software for laptop ensembles I have developed around the Cybernetic Orchestra at McMaster, during the project "Scalable, Collective Traditions of Electronic Sound Performance" (supported by Canada's Social Sciences and Humanities Research Council, SSHRC). The software and some additional helpful files (code/patches) can be downloaded here: http://esp.mcmaster.ca/EspGrid-0.42-OSX-10.7.zip Over the course of the past year, earlier versions of the software have been presented at the Toronto Electroacoustic Symposium, the Audio Engineering Society Convention in San Francisco, and most recently, the live.code.festival in Karlsruhe, Germany. This 0.42 release is a "clean-up release" - with better stability and synchronization. EspGrid has been developed around the ideas of neutrality and hybridity with respect to the languages and environments employed by laptop and live coding performers. The EspGrid application "sits in the background" and takes care of clock synchronization, to a large degree independent of the diverse and multiple "foreground" environments in which performers/creators work. Another participant in the live.code.festival session (chair Alex McLean, if I recall correctly) provided a perfect example of the intent of the EspGrid software: three electronic musicians find themselves on a train together; despite all using different languages/tools to make their music, they each fire up EspGrid and instantly share a tight common clock and a metronome that anyone can control. Jamming ensues... The EspGrid software is being made available to community as free and open source software (GNU public license version 3). The code base of the software includes a large and growing number of unit tests, and development should proceed according to the principles of test-driven development. The rudiments of a help/documentation system are in place. Binary executables exist only for Mac OS X at the present moment but the Windows and Linux ports of the software are the highest, immediate priority following this release. Windows and Linux users in mixed laptop ensembles don't need to wait for these ports however: there is a "side chain" mechanism that allows users/machines without a running grid to piggyback on a user/machine that is running the grid. To get/browse the source code, visit the software's Google code site at: http://code.google.com/p/espgrid Enjoy - and feel free to get in touch for help/issues with the software. I hope that some of you will find this useful, and look forward to working with you on the (gradual) evolution of this tool!

Re: [chuck-users] Get audio samples of adc (fernando alonso)
by Perry Cook 09 Jun '13

09 Jun '13

Either is fine, in fact the samples would be identical in this example. However, if you wanted to apply a gain scaling to the samples coming from adc (as part of a more elaborate patch, for example), then the gain labeled "input" would be the place to do it (I'll tell you why soon). In the example I gave, we could set input.gain to 32768.0 then do the cast of input.last() to int, saving the multiply. For that, you'd need to connect adc through the Gain UG and to blackhole, because it doesn't update/compute without that. Why wouldn't we just change the gain of adc? Well, as a matter of best practices, that is a very bad idea. Turns out that since adc is a persistent and unique UG (like dac and blackhole), as long as the VM runs, the gain change on adc is permanent and global! Imagine how surprised another shred might be if it used adc and found the samples ranging from -32767 to 32768. Bad idea, so I make my students always connect adc to a Gain UG, just avoid the temptation of operating on adc directly. Also, if you connect adc => blackhole (or adc => dac), that connection is also global and permanent, even though the shred that did it might end. So again, operating on adc directly is not good practice. adc.last() is perfectly fine at all times, but I just make my students avoid all use of adc directly. Hope this helps, PRC

You can use adc.last() or adc.chan(0).last() to access the most recent sample. Put that in a single-sample loop that writes to your input[] vector. -Julian On 2013-06-07, at 1:19 PM, chuck-users-request(a)lists.cs.princeton.edu wrote: > Re: Get audio samples of adc (fernando alonso)

Hey, You can collect the values from the ADC by calling it's .last() method. so for example: float values[32]; int i; for (int i;i<values.size;i++) { adc.last() => values[i]; samp => now; } I think what is confusing you is that chuck ugens works sample by sample and not by sending a vector like other languages.
