Loading library (pdp)
by Nicolas Sauret 03 Mar '06

03 Mar '06

Hello everybody, complete beginner speaking... I managed to install Pd-extended. I now try to use pdp and pidip objects but they "don't create". Reading through the list archive, I understood that i was supposed to load the library pdp, but there i'm not quite sure of what i'm doing. is this correct : ? pd -lib /usr/local/app/Pd-0.39.2-extended-test1-linux-i686/lib/pd/extra/pdp.pd_linux/pdp If yes, why do I get "/usr/local/app/Pd-0.39.2-extended-test1-linux-i686/lib/pd/extra/pdp.pd_linux: can't load library" ? If pdp has to be loaded starting PD, is there any other package I'm supposed to load ? Thanks you, Nicolaos.

MIDI file anatomy
by Chuckk Hubbard 03 Mar '06

03 Mar '06

I give up, I think I'll try to just make pitch-bent midi files from my sequencer. Anyone have a good reference for how these files are constructed? Is it possible to make one from PD? I don't have time at this point to make high-end sounds the hard way. I'd far rather do it myself, but the deadlines aren't having it. Thanks. -Chuckk

Hi F.e., > I wonder if there's a way for pyext to know it's deleted, in order, > for example, to remove previously created temp files before it's > killed... > yes there is. Just define a _del(self) method in your pyext class. It gets called when the object is deleted. greetings, Thomas

Hi Martin and Chuck, Pitch bending on every note is one way of doing it, but you need to do this on more than one channel if you want polyphony. you could do this by setting up pitch bends on as many channels as notes in your just intonation scale, or trying not to go more than 16 note polyphony and dynamically changing pitch bend values on any free channel before playing the note there. not sure if this would be much fun in Pd, I did this using java and was not particularly hard, but a reasonable amount of code. the other way I suggested (in a message with the wrong subject title) was to go into scala (http://www.xs4all.nl/~huygensf/scala/), create the scale and export as a tuning dump to a MIDI file, then prepend that dump to the MIDI file you want to use, or the MIDI device you are streaming to. cheers, mark > Martin Peach wrote: > > > I'm not sure if there's a standard way of doing microtonal music in > > MIDI, i.e. do you use Pitch Bend on every note or Continuous Controller? > > > So I parsed the file lou.mid from > http://works.music.columbia.edu/~chris/micromidi/ using midifile and > find that here it's the pitch wheel on almost every note: > midifile: Parsing track[1]... > midifile: tick 0 delta 0 status C0 MIDI: 0xC0 2E: channel 1 Program > Change: 46 > midifile: tick 480 delta 480 status E0 MIDI: 0xE0 00 40 : channel 1 > Pitch Wheel 8192 > midifile: tick 480 delta 0 status 90 MIDI 0x90 3C 63 : channel 1 Note 60 > On velocity 99 > midifile: tick 960 delta 480 status 80 MIDI 0x80 3C 00 : channel 1 Note > 60 Off velocity 0 > midifile: tick 3120 delta 2160 status E0 MIDI: 0xE0 12 34 : channel 1 > Pitch Wheel 6674 > midifile: tick 3120 delta 0 status 90 MIDI 0x90 3D 4F : channel 1 Note > 61 On velocity 79 > midifile: tick 3600 delta 480 status 80 MIDI 0x80 3D 00 : channel 1 Note > 61 Off velocity 0 > ... > > Martin

big [hid] changes...
by Hans-Christoph Steiner 02 Mar '06

02 Mar '06

So my bruising experience of porting [hid] to Windows has lead me to a new approach for [hid] on all platforms. Currently, as it is now, [hid] is not a HID API, but really an input API like the Linux input API. I think it is useful to have a real USB HID API as well as a Linux-style input API within Pd, so I plan on changing things in a big way to support this, and I wanted to get some feedback on the ideas before forging ahead, especially considering that none of this will be backwards compatible with [hid] (though the input-style API will be very similar and based on the same code). First off, [hid] will become a Pd object version of libhid, so it'll be a regular USB HID API, but with some Pd-style specifics. Yes, there is some pain to this conversion, but I think we'll all be better off in the long run. I hope to make a corresponding [usb] object based on libusb which can be used in conjunction with the new [hid]. This will be a much more flexible approach, but there is still much design work and research to be done before I know how feasible it is. Second, what is now [hid] will be renamed and I'll implement some biggish changes that I have been meaning to do which are not backwards compatible. The idea for the new object is to fully embrace the idea of the Linux-input-style abstraction layer. I am not sure whether this should be a separate object with its own C code, or whether it should also be based on [usb] and [hid]. Then the existing [joystick], [mouse], [tablet], [gamepad], etc. objects will be based on this new object and _will_ be backwards compatible. So only more advanced users of the [hid] objects will be affected. But the first step is to find a name for this new object. I have been thinking either [human->pd] or [you->pd] to highlight that its meant for getting data from people into Pd. Plus I think that "->" makes a nice conversion symbol. Ideas, thoughts, criticisms, comments are all welcomed and are in fact what I am after. .hc ________________________________________________________________________ ____ If you are not part of the solution, you are part of the problem. - Eldridge Cleaver

Ubuntu OSX pdp pidip stuff
by bigswift＠cox.net 02 Mar '06

02 Mar '06

ok, well i guess around 6;30, ye olde linux fever hit me and i installed ubuntu fresh on an 80GB older 533 G4 i did not install OSX. Everything seems to be working well except that the headphone sound does not work and currently all sound is emitted through the internal PC speaker. everything thing else is pretty straightforward hopefully some Alsa configging will sort that out. there is a nice marked speed difference from the 533 running OSX 10.3.9 to ubuntu 5.10 breezy it really does give the machine that old zip again pd 0.38-4 installed from source and works fine pdp 0.12.5-test4 works fine as does pidip 0.12.20 are these the current versions? i cannot seem to get a pdp_qt and when i run pdp_freeframe from a pdp_yqt i get a NOT A PDP_IMAGE d ??? ok sevvy, i installed linux.

midi learn, osc learn - state saving
by patrick 02 Mar '06

02 Mar '06

hi all, in the process of making an audio patch (in, out, fx, seq etc.) link with open sound control and my uc-33e (midi controller). i was using memento for the first version of my patch. now i tried the simpler state-saving patch from frank for pd 0.39.2 - nice! but still missing to pd is a midi learn and osc learn. it works like that: 1) bang "learning" 2) touch a gui 3) move 1 controller from your device (uc-33e in my case) 3) or move 1 gui from another computer link by osc 4) save this setup anything done like that or alternative solution? pat
