best way of doing this
by Chris McCormick 05 Jun '02

05 Jun '02

Hi, I want to do the following quantization operation: multiply my signal (which is between 0 and 1) by some number (say 1000) round it to the nearest integer divide my signal again by 1000 this effectively makes the signal snap to 1000ths between 0 and 1 and as you make the quantizing number smaller you get a really nice harmonically rich crunchyness come through which sounds great when you filter it (sounds wicked on drum loops). Basically i'm wondering what's the best way of doing this in Pd? I can't seem to find any 'round to the nearest integer' operation that will work on signals. Thx in advance for your help!

Floating point vs. Integer
by David Sabine 05 Jun '02

05 Jun '02

Hello all, If PD keeps all numbers in 32-bit floating point, then why is the [int] object necessary or useful? Does the [int] object save CPU or provide any functionality that [float] does not? Many thanks, Dave S

[FONTS] tiny font
by Andre Schmidt 05 Jun '02

hi all, thnx for all the screensize&os replies, keep'em comin ! CK send me an interesting link http://www.be-e.de/files_00.htm and my fingers started to itch rightaway :) so here is it, a 5x5 pixels font. (small enough?) (looks nice on 17" @ 800x600) [5x7 would maybe look more readable] BUT, before i/we haven't solved the problem using/installing new fonts on all OS i'm not giving any beta version fonts for usage :( windows: just copy to windows/fonts folder. installs automaticly [deinstall; delete from fonts folder] linux: ??? mac: ??? irix: ??? thnx -andre

The great thing about [mtof] is that you don't have to limit yourself to integers. Thus: [notein] | | [spigot] | [* 1.33] | [mtof] | [osc~] | [dac~] This would give you instant microtonalities. It would just be a matter or working on the math to convert key numbers to the number of steps you want per octave or such. The [spigot] in the example patch acts as a gate to only allow the note-on note number to be sent to the synth by ignoring note of velocity 0. Makes for a better monophonic synth. good luck and have fun! Sam

Re: [PD] Input Controllers for Pd with finer grain than MIDI
by David McCallum 05 Jun '02

05 Jun '02

I've been tinkering around with this. Do you have it in patch form? Your else if statement doesn't take into account values between last-output and last-output+jitter. Which isn't exactly everything else. Is this intentional? If it's supposed to be like that, should I be using two moses (mosees?) to split that? At the moment I've been assuming that "else" really is everything not included in the if statement and using one moses. Also, do you have any tips for tuning the filter? I've tried to get it pretty close but it still jitters. I imagine it's not perfect, though. tanks David McCallum At 08:42 AM 31/05/2002 -0700, you wrote: >Here's a dejitter algo I use on sliders, joysticks, etc...

real time time-stretching ?
by oliver 05 Jun '02

05 Jun '02

hi list, "Gradually slow down a recorded sound without altering its pitch or timbre". (steve reich, "slow motion sound", 1968) I'm looking for a not too CPU-expensive way of gradually time-stretching a sound in real-time without hearing too many "windows". i didn't find much about this subject in the mailing list database, and will check out the few results, but maybe in the meanwhile someone has gotten further in this matter already ?... it should be something like in 7.stuff\soundfile-tools\3.phase.vocoder.pd. but this patch is a little unhandy and can not produce the sound in its original length without artefacts... oliver

best method for non fft spitch shiting
by oliver 05 Jun '02

05 Jun '02

hi, you once spoke about a patch for time-stretching and described it like this... <I once used the block~ to do multiple overlap when reading from a delay <line.. <this worked pretty good for "time stretching", maybe a similar soultuion <can be applied to pitch shifting .. <Guenter i cannot imagine what you did, but i'm interested. was it real-time ? did it sound good? is it downloadable somewhere ? hoping for help oliver

microtuning in pd?
by booey chewy 04 Jun '02

04 Jun '02

Hello, I am a newbie. I was wondering what sort of microtonality has been developed for pd. Ideally I would want to pitchbend incoming midi data from cubase or cakewalk or something, or quantize the pitch data from one the step sequencer objects I have seen floating around. The ideal way for this to occur would be direct importation of scales from scala files. todd __________________________________________________________________ Gesendet von Yahoo!

IEM is/isnot included?
by David Sabine 04 Jun '02

04 Jun '02

Hello all, Is the IEM library now included (as a native library) in PD? I'm using 0.35 test 24 on Windows XP. The reason I ask is that when I start PD without explicitly calling the IEM library from the command line, the IEMLIB objects such as [bng] still work and are present in my patches. Is this because IEMLIB is 'present' on my machine or is this because IEMLIB are part of and called directly from PD's source code? Many thanks. Dave S

by rat＠telecoma.net 04 Jun '02

hi, is there a possibility to put an image on the canvas ? i guess one has to write an external for this purpose. if someone already played around with something like that it would be great if he could share. if not how would i start to do so ? is it possible anyhow ? thx erich
