Re: [PD] plot - 1000 element limit?
Hi Derek - Pd hasn't ever been carefully tested in cases where objects send huge atomic messages to the gui - but in looking at teh code I don't see that there are any limits to their size (there used to be fixed buffer sizes here and there but it looks like it's all fixed now). So if you want, you can just remove the size limitations in g_template.c and recompile. I'm scared to do this in the Pd release since I don't really know how to know whether it will really work robustly on all posible OSes etc. cheers Miller On Wed, Jul 22, 2020 at 07:04:28PM -0700, Derek Kwan wrote: > Hello list, > > Long time, no e-mail. > > It seems there's a limit in [plot] to only plot the first 1000 elements > of a struct's array (at least for me on Ubuntu 18.04, pd 0.51)?

Thank you both, I understand now what I was doing wrong!

Re: [PD] switch-and-ramp technique
Here's an abstraction I call rampdown~ - any time you want you can bang the second inlet (control) and simultaneously cut off (brutally zero out) the left (audio) inlet, as if you were stealing a voice that was actively playing. I use this quite a bit for monophonic voice stealing, as when you want to repeatedly trigger a monophonic sampler. #N canvas 105 474 450 300 10; #X obj 64 68 inlet~; #X obj 63 205 +~; #X obj 64 255 outlet~; #X obj 79 169 line~; #X obj 183 86 inlet; #X obj 183 190 snapshot~; #X msg 79 141 \$1 \, 0 100; #X obj 183 109 b; #X connect 0 0 1 0; #X connect 1 0 2 0; #X connect 1 0 5 0; #X connect 3 0 1 1; #X connect 4 0 7 0; #X connect 5 0 6 0; #X connect 6 0 3 0; #X connect 7 0 5 0; cheers Miller On Thu, Jul 23, 2020 at 09:47:54AM +0200, Maximiliano Estudies wrote: > Hello list, > > I'm working through "The theory and technique of electronic music" for the > second time and having some trouble implementing the switch-and-ramp > technique described in 4.3.2.

[PD] switch-and-ramp technique
Hello list, I'm working through "The theory and technique of electronic music" for the second time and having some trouble implementing the switch-and-ramp technique described in 4.3.2. I understand the concept but my current implementation clicks harshly when I retrigger the envelope. Does anybody have an implementation I could look at? -- Maximiliano Estudies *VDT Referat Beschallung* +49 176 36784771 omslo.com maxiestudies.com ___ Pd-list@lists.iem.at mailing list UNSUBSCRIBE and account-management -> https://lists.puredata.info/listinfo/pd-list
