Sharing sound-fonts (again)
by Larry Troxler 06 Feb '05

06 Feb '05

First, my aplogies to this list that I volunteered to do this mod to fluid~ and probably almost a year later, haven't had the time to tackle it yet. Well, I might actually have a few hours later on today to work on this, and just would like to see if the work would still be revelant. The motivation in my case is to use a large piano sounfont, loaded only once, and to use multiple instances of fluid~ to seperately process each voice. The simplest idea I came up with would be to simply compare the file strings, and if the same, to share the soundfount rather than loading it again. If I don't hear from anyone about a better approach, I hope to go ahead and tackle this. One related questions - is it safe to use C++ STL as is, or should I redefine the allocator to use pd_new (or whatever it's called)? Larry

Parallel Printer Port External?
by Phillip Stearns 05 Feb '05

05 Feb '05

Has anyone written anything similar to comport for the parallel printer ports? Can anyone point me in the right direction for writing an external that would be able to send and receive data from the parallel ports? Thanks Phil --------------------------------- Do you Yahoo!?

Also... I'm using waveshaping for distortion. To me Chebychev polys seem more of a practice found in synthesis as opposed to signal processing. I've found that the fractional power equations offer a very good approximation of traditional analog distortion. Other interesting equations are those based off sums of odd powers. I've also tried various combinations of periodic equations as well (atan, tan, acos, etc)... Well... this is all for people more interested in playing with distortion. Cool thing about the arrays, though, is that you can draw in data on the fly. Yeah noise! Thanks to all those who've responded! Cheers- Phil --------------------------------- Do you Yahoo!? Yahoo!

Wave Shaping
by Phillip Stearns 05 Feb '05

05 Feb '05

Which is a less processor intensive method of wave shaping: using writing an equation once to a table and modulating tabread4~ with an incoming signal or running that signal through the expr~ (the exquation I'm using is [epxr~ $v1-($v1*$v2) + if($v1<=0, -pow(-$v1, 0.15), pow($v1, 0.15))*$v2] Where $v1 is the incoming audio signal and $v2 is value from 0 to 1. I have had success using expr~ but have a suspicion that tabread4~ might be a little less processor hungry. Anyone have any clue? Thanks -Phil --------------------------------- Do you Yahoo!? Yahoo!

mp3 playing external
by Bartlomiej Bazior 05 Feb '05

05 Feb '05

Hi all, I'm looking for some external that can play mp3 files with variable speed. I know about readanysf~ but it seems it's linux/osx only (I use windoze). Is there anything similar available on "my" os? Or maybe someone somehow got that readanysf working on win? Any help will be... helpful :-) cheers, Bart -- Doesn't matter if I'm paranoid - they're still after me.

Hi List ! Happy new year to all the computer nerds ;-) A simple question, does anybody have a good recommendation for a midi-capable foot-controller. Like a wah-wah with midi out ??? Thanks Luigi

for anyone that is interested, i was able to get the alsa seq code from devel_0_38 to work in pd-0.38.0 (skipping the tk stuff) with minor changes to s_midi.c and the makefile. let me know if you want a patch. -s
