reply-to of this list

Hello, is there a special reason why this list's emails don't have a reply-to header? I find it rather annoying that when I click 'reply' I always get the author of the message as the recipient of the reply. With all other lists I have subscribed clicking 'reply' produces an email addressed to the list. Thanks for any info on this Urs

msg problem: calculate 2 sinesum and normalize both
by eni 22 Jul '05

22 Jul '05

hi list I'm building a dynamic additive synth with sinesum-cosinesum. but I've some problems with [sine When pd (0.38-4-extended-RC1) calculates 2 sinesum and normalizes them it seems that the order is rather important . the following examples work (osx pd0.37-1) as expected , in pd0.38-4 the first msg doesn't update the last array correctly . [; array1 sinesum 16 0 0.5 0 0.5 1; array1 normalize 1; array2 sinesum 16 0 0.5 0 0.5 1; array2 normalize 1( [; array1 sinesum 16 0 0.5 0 0.5 1; array2 sinesum 16 0 0.5 0 0.5 1; array1 normalize 1; array2 normalize 1( I must use the order of the first msg. In my solution I just bang the msg twice [t b b] (works but isn't it a dirty-hack?) I wonder if that needs more cpu??? an other (dirty)solution I thought was to delay the normalize but I couldn't figure out a deltime which was stable 50ms sometimes display both array and sometimes not! thanx eni #N canvas 250 81 293 333 10; #N canvas 0 22 450 300 graph1 0; #X array out2 19 float 0; #X coords 0 1 18 -1 128 128 1; #X restore 45 154 graph; #N canvas 0 22 450 300 graph1 0; #X array out 19 float 0; #X coords 0 1 18 -1 128 128 1; #X restore 45 19 graph; #N canvas 654 47 502 520 doesnt 0; #X obj 57 148 t b b b b; #X msg 57 260 \; out2 normalize 1; #X msg 95 198 \; out normalize 1; #X obj 18 295 t b b b b; #X msg 18 407 \; out2 normalize 1; #X msg 56 345 \; out normalize 1; #X obj 18 129 bng 15 250 50 0 empty empty empty 0 -6 0 8 -262144 -1 -1; #X obj 57 129 bng 15 250 50 0 empty empty empty 0 -6 0 8 -262144 -1 -1; #X text 82 127 <- calculate 2 (co)sinesum; #X text 17 11 I have this behaviour(bug?) in pd-0.38-4-extended-RC1.app in pd-0.37-1 it works fine as expected.

pd using Jack DIO errors - but no xruns
by Brad Fuller 21 Jul '05

21 Jul '05

I'm having a bit a problem with pd. It runs fine most of the time, but every once in a while there are DIO errors. Changing the "delay" setting doesn't seem to do anything. The pd CPU load is at most 5% and 1.2% in jack Pressing the DIO errors button reveals "A/D/A" sync and "unknown" The patch is only doing some logic and playing back wav files. Any ideas where I can look for the culprit? Hey, are there any test patches that run the gamut of processing complexity? TIA brad

Re: [PD] GApop compilation in OSX

So strange. After cvs update of both flext and gapop, I did bash build.sh pd gcc and sudo bash build.sh pd gcc install on flext, and everything went ok...then I went to grh/GApop and did: waldorf:/usr/local/lib/pd/extra/externals/grh/GApop dc$ sh ../../grill/flext/build.sh pd gcc which definitely pointed to the flext sources I'd just successfully built after cvs update. I reviewed .pdrc and it pointed to -path /usr/local/lib/pd/extra/externals/grh, and asked for -lib GApop Somehow though, pd still crashes. Could it be a pd version problem? Should I up to 0.39? d -- # David Plans Casal problem.each { |day| assert_nil(spoon) }

[OT] Converting hex values to individual bytes
by B. Bogart 20 Jul '05

20 Jul '05

Hey all, I'm working on an abstraction to control a Canon VC-C50i serial-control camera from PD. Things are going pretty well and I have the basic trigger commands done. The problem I'm running into is the continuous controls. Lets take the pan as an example. The documentation states that the minimum angle is 0x7c87, while the maximum is 0x8379. To set the angle of the camera I need to issue a command made of up individual bytes (converted into decimal for comport) in this case something like: 255,48,48,0,98,p,p,p,p,t,t,t,t,239 (in decimal) Where the four P bytes are the panning angle and the four t bytes are the tilt angle. So what I want to do is to take a range (say floats 0-1) to map to the min and max panning angle. How do I convert the miniumum angle (31879 in decimal) to four seperate decimal messages for use in the above command? Obviously I would like the granularity of the steps to be continuous so I could do some interpolation without sending invalid values. I could sit here for a couple hours to figure it out, but I thought someone on the list would have a short cut for me. Oh and according to the documentation (and testing) the following is correct: Hex value | decimal message ----------+------------------ 0x7c87 = 55,67,56,55 (min) 0x8379 = 56,51,55,57 (max) Thank you! B.
