Re: [PD] speedlimit of data in Pd - until in reverse order
Hi, thanks for your replies, I wasn't aware of the function of [until]'s right inlet. It does work much faster that way. This is a kind of general problem: What is the speedlimit of data in Pd? How many operations can be done until a stack overflow occurs? There is a place where the limit is hardcoded-- that's what gives the buffer overflow error. It protects against infinite recursive loops in some cases but not in others, as well as being a nuisance when you need to have a recursive loop more than 1,000 levels deep. I think matju precisely explained how it works on the list somewhere (definitely more precisely than I can). ok, I'll look for that ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] speedlimit of data in Pd
thanks, that and other's [until] suggestion answers most of the questions. you get a stack overflow if you have about 400 (iirc) objects in a row. whenever an objects sends something to its outlets, the stack is saved and not restored until everything below it has executed. there has been some talk about making the maximum stack depth settable as a cmdline arg, but i guess nobody every implemented that. (usually you want a maximum stack depth, as it allows you to survive a recursive patch without exit condition) This is a kind of general problem: What is the speedlimit of data in Pd? what do you mean by speedlimit. How many operations can be done until a stack overflow occurs? That also i don't get how speedlimit and stack overflow go together in this context. the problem is more: since Pd-messages are executed as fast as possible, you need to use the stack. or put the other way round: if you can live with breaking linearity (by splitting a message chain using [delay 0]), then the stack will not overflow. happens when I try to automatically load the contents of a not-so-big [textfile] into an array with a click - unless I add a [del 1] to the loop. If the operation isn't in realtime, the problem can be circumvented, but anyway the issue is there. depends on how you do the loading. avoid recursion, use iteration. (read: use [until] rather than feedback) How is it possible to increase the control rate in Pd? I tried changing buy a faster CPU. the control rate in Pd is only limited by the CPU. if (and only if) you have enough idle time to do some DSP-processing inbetween message processing, then your messages will be done in bursts every 64 samples. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] FTM for PD
Hello list has anyone compiled FTM for PD in mac OSX 10.6?? or is their a UB for installing, or maybe is their somewhere to find the compiled library??? thanx -- Lic.

[PD] Data Structures - Scaling Visual Display - (1:10)(2:200)
I can't remember where I've seen it but you can create a struct like so... [struct structname float x(1:10)(2:200)] ...such that x displays more tightly or loosely and with boundaries depending on the values in the brackets. But I can't figure how to enter the values properly! My question is, how do you set the values in the brackets? What do they refer to?! Is there any documentation available on this? Thanks, John. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] Data Structures - Scaling Visual Display - (1:10)(2:200)
There's a somewhat lame explanation in doc/4.data.structures/09.scaling.pd -- in brief, 1:10 in the example below says that the value of x is restricted to the range 1-10, and this range is linearly rescaled to values 2-200 in the coordinates of the patch. cheers Miller On Fri, Jun 29, 2012 at 06:50:21PM -0700, JF wrote: I can't remember where I've seen it but you can create a struct like so...
