As for casting durations or floats to time one should always ask how the newly made time relates to the one(s) we already have? Most logical would be that: minute $ time => time sometime; refered to "one minute after the VM started". But it could also refer to "one minute after this shred started". I find it more clear syntatically if we had predifined global and local time variables of VMstart and me.start (or me.birth). Then it would be clear from the syntax what is meant. VMstart + minute => time sometime; //As opposed to: me.start + minute => time anothertime; >>Kassen wrote: >>As for actual use, I could imagine that referring to absolute moments in time could become useful when writing a score, especially with some sort of sorting, Csound style. Maybe there are other better uses, maybe it's all quite academic? I'm already enthusiastic there are people that have a position on this too. That's what I thought when I first read about time in the ChucK manual. And I did make some tests with absolute time (relative to shred start time) ie. Calling: now => time start; //1st line And then making an array with [time,note,velocity,note_duration] float vectors to drive a score-player that would play the notes and chuck the time of the next note to now: spork~instrument(pitch,velocity,duration); start + time_of_the_next_note::second => now; But then I realized that this was a very unflexible way of doing things. If I wanted to add a new melody in between the old notes I would have to modify all of the times after it. Also tempo changes would be virtually impossible. So instead I went with an array of [time_separation,note,velocity,note_duration] vectors. Now the score-player would go: spork~instrument(pitch,velocity,duration); time_separation::second => now; //I recommend using a global duration of a quarter note here instead of an absolute duration of a second ...and it already felt more chuckish. :) Now adding new notes to the score needed no modification on the ones already present. I'm still thinking for the most effective way of changing the tempo on the fly... Thine, -Pyry

I personally like the way time and duration are done right now, that you cannot make an explicit time-type variables. Those kind of things would only be limiting because they always had to refer to VM-time. If they instead refered to some kind of shred birth time then "chucking time to now" would lose meaning and unambiguity. And we can already define a birth time and times relative to that with the current state of affairs. //First line now => time birth_time; birth_time + 4::day => time four_days_from_birth; birth_time + minute => now; //Wait until the shred is one minute old >>; //Stuff four_days_from_birth => now; //Assuming it hasn't been four days yet. If it has then this chuck throws an exception. That should be enough. Requesting time casting sounds to me of requesting different kinds of time like VM time, shred time, real time, tea time and what not... :) There should only be one time. VM time. I think of it like a kind of a big bang time... everything else is relative. (Did someone say Einstein?) -Pyry, (Frostburn)

cast dur to time?
by Kassen 07 Jan '08

07 Jan '08

Dear list (and language designers in particular), this is legal; now + 2::second => time later; so, we know that time and duration are quite similar things (we already knew that ourselves but now we know ChucK agrees). However, this isn't legal; 2::second $ time => time later; I tried this, intending "later" to refer to the moment 2 seconds after the VM sprang to life. Are there good reasons not to allow the casting from time to dur and dur to time? Yours, Kas.

am i wrong that you can't get the state of the caps-lock button? you can, with Hid, see whether it's gets pressed or released, but you can't tell what state it's in. dt

I'll look into it. Eventually, I would like to have dual screen recording for presenter and presentation. It seems possible that we may be able to record a single camera version.

06 Jan '08

January Bay Area Computer Music Technology Group Meetup Our January 10th Bay Area Computer Music Technology meetup will run from 7:30-9:30pm and will be hosted by Pyramind (www.pyramind.com) @ 832 Folsom St, San Francisco. You must RSVP for this event as we may need to verify names at the door. RSVP here: http://electronicmusic.meetup.com/152/calendar/6710904/ Our presentations this month: - Andrew Benson from Cycling 74 will present on the new features in Max 5! - Craig Latta will be presenting his Smalltalk based musical livecoding project called "quoth" that uses executable natural language. Craig presented an exciting preview of quoth at our December Stanford Meetup. - Lightning talk by Ge Wang on the upcoming ChucK workshop and an update on the forming Laptop Orchestras - A lightning talk by you? If you would like to do a lightning talk (5 minute presentation) come with your laptop. Let me know in advance or just come prepared and let me know when you see me that you would like to present. Also, let me mention that there are two other upcoming events in January: - January 13th (Sunday): Ge Wang will be teaching a workshop on ChucK programming at Stanford (more info at http://electronicmusic.meetup.com/152/calendar/6710874/) - January 24th (Thursday): Build Ruby Language Audio APIs Brainstorming session will meet in SF (Venue TBD; Learn more here: http://electronicmusic.meetup.com/152/calendar/6806947/ ) All the best, Noah Thorp Bay Area Computer Music Technology Group Organizer ABOUT THE PARTICIPANTS Cycling 74 ---------------- Cycling '74 creates software for the specialized needs of artists, educators, and researchers working with audio, visual media, and physical computing. Our visual programming tools Max/MSP and Jitter serve as the creative engine behind thousands of innovative projects. More information about Cycling '74 and its entire product line available at http://www.cycling74.com Craig Latta ----------------- Craig Latta is descended from a long line of itinerant researchers. Asking only for a fast network connection and an occasional glimpse at the sky, he explores the hinterlands of experimental music and computer science. Craig earned simultaneous bachelor degrees in music and computer science from UC Berkeley in 1991. Later that year, he discovered dynamic object programming with the Smalltalk system and realized that improvisational musical informatics was his thing. He enjoyed a variety of ambitious projects at ParcPlace Systems, Atari Games, Interval Research, the IBM Watson Research Center, and the Bootstrap Institute. In 2004, he fell in with the highly suspicious "livecoding" crowd (toplap.org), and two years after that joined the multimedia improv group "dud" (dudland.com). This afternoon he worked for the Fuji Xerox Palo Alto Laboratory. At twilight he went for a nice walk. Now, under cover of night, he pursues the NetJam project (netjam.org), a music improvisation network. Pyramind - Institute For Advanced Digital Audio Training (our host) ----------------------------------------------------------------------------------------------------- Designed for the professional and developing recording artist, Pyramind's certificate programs are the result of over fifty years of collective experience in: production, composition, sound design, engineering, mixing, mastering, studio design and installation. The curriculums are firmly based on the three foundations needed for success: technology, creativity and business. Pyramind's unique training programs include both Apple and Digidesign manufacture certificates. Website: http://www.pyramind.com/ Many thanks to Pyramind for hosting our January event!

an OSC bug that took a little bit to isolate. i've put it on the bug wiki: http://wiki.cs.princeton.edu/index.php/OSC_multiple_port_bug not the end of the world, but it can raise issues when working with multiple machines and perhaps GUI apps using OSC to communicate with chuck. dt
