to clip or not?
by Krzysztof Czaja 15 Apr '02

15 Apr '02

hi all, I have changed my mind, and made some tests of that comb~ thing, putting a mac with msp alongside a pc with Pd. As far as I can tell, the comparison test has been passed for both static, and flanged effects. One thing remains unclear, though: -- the feedback gain input is never clipped in msp version, and it is easy to produce comb~'s output level reaching `infinity'... Should I keep it that way? And also: how about using more than 10 ms for a default maximum delay time (making the two combs slightly incompatible)? Krzysztof

any one have a working version of this help file . i have tried to install it on another computer and it gives me different errors but in both cases the xgroove~ object itself doesnt come up in the patcher window . here is a sample of the errors i am getting with pd-35-test17 either with the iemlib installed and with out : error: canvas: no method for 'intatom' ... you might be able to track this down from the Find menu. xgroove~.pd 0 0 17 0 (hsl->text) connection failed xgroove~.pd 2 0 17 1 (gatom->text) connection failed xgroove~.pd 3 0 17 2 (gatom->text) connection failed xgroove~.pd 11 0 17 0 (message->text) connection failed xgroove~.pd 12 0 17 0 (bng->text) connection failed xgroove~.pd 13 0 17 0 (message->text) connection failed xgroove~.pd 16 0 17 0 (message->text) connection failed xgroove~.pd 17 0 15 0 (text->dac~) connection failed xgroove~.pd 17 0 15 1 (text->dac~) connection failed xgroove~.pd 17 1 8 0 (text->snapshot~) connection failed xgroove~.pd 17 2 4 0 (text->gatom) connection failed xgroove~.pd 17 3 5 0 (text->gatom) connection failed xgroove~.pd 24 0 34 0 (text->message) connection failed xgroove~.pd 26 0 17 0 (text->text) connection failed xgroove~.pd 32 0 17 0 (message->text) connection failed xgroove~.pd 33 0 17 0 (message->text) connection failed xgroove~.pd 34 0 17 0 (message->text) connection failed xgroove~.pd 35 0 31 0 (message->???) connection failed i have tried it with pd-34-4 also and it doesnt work there either . i am using the latest version of xsample~ [0.2.2] . joge .

No problem, only their on my machine at home so the earliest I can send them to you is in the morning. I actually thought it was CK who was looking for them? some of these long 'mix and match' emails can get quite confusing.

by Andre Schmidt 15 Apr '02

[PD][announce] new objects: maxlib
by Olaf Matthes 15 Apr '02

15 Apr '02

Hi all, I have started to collect some useful (non-tilde) objects in a library called "maxlib" which stands for "music analysis extensions library". Win only at the moment but I'm shure it compiles on Linux... (makefile might need some changes) The objects can be very useful to analyse any musical performance. Some of the objects are 'borrowed' from Max (they are not ported but rewritten for Pd - cheap immitations). Objects included (more to come soon, as I find the time to make them 'ready for the masses'): borax - the "swiss army knife" (Todd Winkler) for music analysis: it takes pitch and velocity from a notein or makenote and calculates nine different parameters (identical to the Max object with the same name) ignore - lets input only get through when it stays unchanged for a specified time match - checks whether a list of entering numbers (only floats supported at the moment) matches its arguments (similar to the Max object with the same name: we take floats instead of lists as input) pitch - outputs pitch (MIDI note number and 'real' key name as symbol), pitch class, interval and register of an incoming note number speedlim - lets information (floats) through only every N milliseconds, especially useful to reduce continuos controller data (identical to the Max object with the same name) Download at http://www.akustische-kunst.de/puredata/maxlib/ Olaf

OSC extern and csound~
by vanDongen/Gilcher 15 Apr '02

15 Apr '02

Hi all, I can't get pd to communicate sensibly with my csound orchestra using the OSC external. Does anybody have an example of the mesage format that [cool-name]csound requires, and how to send it. How many numbers should I send, an how are they seperated? thanks Gerard

win98: wrong sample rate
by smoerk 15 Apr '02

15 Apr '02

hello, i don't know how i could use 44100 sample rate with my sound card. it seems that my sound cards always expects 32000 hz from pd. i have to start pd with -r 32000 to get a clean sound. the sound card (SoundMax on board) works with other audio software with 44100 hz without problems.

ASIO latency
by sme 15 Apr '02

15 Apr '02

latency again, ... PD is running on W2k with the RME (Multiface) ASIO drivers, also with multichannels (thanks to joreg), but latency is still bad. i measure a latency of ~1536 samples, although pd printout shows a latency of 128 samples at the startup. how can i reduce that? other progs like cubase donÅ½t show that behaviour (using the same asio-driver), does portaudio/pd have some additional buffers? marius.
