Has anyone written a variable delay object that can go to zero? I know feedback wouldn't be possible, but I've found a couple of situations where such an object would be useful. Isn't there a minimum delay time of one block with delwrite~ and vd~?

vd~ ?

This topic is one of the mysteries in PD, but it is explained in 3.audio.examples/72.execution.order.pd
I had to contemplate this a lot, before I understood, what's going on there.
Basicall you have to make sure, that the delwrite is executed before delread or vd~, then you can get delay times as small as zero, without a block in between.

Ah, got it. Great, thanks for the pointer :)

hi Ben,
comb~ from the cyclone library implements a variable delay with both feedback and feed-forward control. Delay time, specified in ms, is clipped between one sample-period and a maximum defined by the user.
Unfortunately, being an msp's comb~ clone, it uses a linear interpolation vs. 4-point interpolation in vd~. There are still some incompatibilities, though: a larger default value of the maximum delay, and the feedback gain clipped at above 0.999 -- I have not decided yet, if these should be kept or gone (I would appreciate comments, and bug reports too:-)

Dear folks i was wondering if there are any OSX externals that i may use. I am particulary interested in the plugin~ and vst~ externals but i am 1.) not sure if ladpsa will work under OSX 2.) unsure if regular pd externals will compile correctly
I see that there are a few Yves Exts including the wonderful cooled~ but has anyone else developed any others?
any hints would be greatly appreciated cheers

Is cyclone available anywhere online? I can't find it on pure-data.org...
Thanks, Greg

hi all,
http://suita.chopin.edu.pl/~czaja/miXed/externs/cyclone.html
is the cyclone page. This is now linux-only (I will upload a snapshot with windows libs later this week).
I think the library (at least the 'hammer' part of version 0.1) should enter the 'alpha-test' phase soon, otherwise the bugs would proliferate into an unmanageable pile...
By 'alpha-testing' I mean, mainly, not using on stage, but if anybody was willing to perform alpha-testing for real, like stress-testing, max/msp-compatibility testing, etc., and looking for bugs in the code, I would be more than happy.
Btw, the newest snapshot includes a (completely untested) 'pv' (private value) class. It is like the 'value' class, but its objects handle values which are local to a window (and its sub-windows), and which can be messages of any type and length (not only floats).

This looks great... any NT ports planned in the near future?
