	---------- Forwarded message ---------- Date: Sun, 22 Nov 2015 13:42:15 -0500 From: Beinan Li To: csound users' discussions Subject: [Old-Csnd] Standard method for generating an event of infinite duration Hi Csound, For creating an "infinitely long" event, I tried i1 0 -1 and it didn't work (no sound). Then I bumped into this old post: http://csound.1045644.n5.nabble.com/R-Re-Infinite-Duration-Proposal-td1115458 .html where Steven explained why this can't work (in 2010) and the ideal case of an always-online sound engine, which is what I want. Now what is the state-of-the-art in this area other than "cheating" with a huge p3?

	Also with current Csound, if an empty score is given when Csound starts, it will automatically keep running. In this scenario, Csound internally will generate a mock note with length z. I do think the engine could be modified to operate without direct knowledge of "done-ness" of the pending events and active instances. For all intents and purposes though, having a mock note in the score with length z gives the desired behavior. The engineering cost to implement it "properly" does not seem worth it considering the known workaround. However, it may be that there are use cases outside of what we know that might make it worth it to implement. Also, since we're tracking issues on Github now, it wouldn't hurt to add an issue and then it would at least be something we could track.

	Thank you both, jpff and Steven. @Steven Also with current Csound, if an empty score is given when Csound starts, it will automatically keep running. In this scenario, Csound internally will generate a mock note with length z. Is current Csound the latest official release or dev branch on GitHub? I'm running "Csound version 6.05 (double samples) May 13 2015" on OS X. I do think the engine could be modified to operate without direct knowledge of "done-ness" of the pending events and active instances. For all intents and purposes though, having a mock note in the score with length z gives the desired behavior. The engineering cost to implement it "properly" does not seem worth it considering the known workaround. However, it may be that there are use cases outside of what we know that might make it worth it to implement. Also, since we're tracking issues on Github now, it wouldn't hurt to add an issue and then it would at least be something we could track. The workarounds are acceptable to me. It would be nice if the info were made highly visible in the FLOSS manual somewhere. Apologies if it's already there (a simple search of "fudge" or "z" leads me nowhere). But I understand that there will be a delay if the features are new. Thanks again!
