To put out sysex MIDI, theoretically in either ALSA or OSS, send the bytes out serially, as in 247, NN, NN, 240, not in a list as in 247 NN NN 240. OSS has, IIRC, been deprecated for many years now. ALSA should be the correct one to use on Linux. And, also, for the past year or so there's been a new JACK MIDI API which is a lot cleaner (and strongly-timed) than ALSA, although it of course uses ALSA for transmission to actual MIDI devices. -ken ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

But, if you know something I don't... I have open ears. Nope, you got real-time there, for sure. I was wrong then. Ubuntu runs so nicely on a laptop though... would hate to switch after finding such an easy-to-operate linux distribution because pd and only pd doesn't like jack in realtime. Dunno. You're playing Xrun whack-a-mole. Done that; it's not fun. Here's what I did to RT-ify my system (on Debian, but Ubuntu is based on it): http://www.restivo.org/blog/archives/preparing-a-debian-etch-system-for-audio-use Also, I expect you know to use chrt to give the IRQ of your audio interface top priority, higher than JACK and any other process. That's a crucial step. If I omit that, then I get clicks and pops too, which is why I wrote a script to do it automatically. You could also install and configure the rtirq package, which works great too. -ken ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] wierd feedback popping with pd/freebob/jack/rt
2008/5/20 Rich E [EMAIL PROTECTED]: Currently, Pd-0.40.3-extended from the autobuiilds. While I think this is occurring on every version on Pd I have tried since I installed Hardy (which is alot), I should do some testing to verify that. Another thing; opening Audacity only cures things for a bit, until I do something like open another patch in pd. Then, the glitch happens again, I restart audacity, and it goes away. I'll try some testing on 0.39 - .41 vanilla when I have a moment. IIRC, Ubuntu RT kernel is not actually Real Time (i.e. with Ingo patches), just a desktop RT which is not very useful for audio and certainly not enough for JACK apps of any heft. The pops/clicks phenomenon you are noticing that gets resolved by starting or killing another JACK app, is something I've experienced before. It happens when some app gets an Xrun or otherwise can't process audio in time. From that point forward it clicks and, in my experience, distorts as well with some bitcrushing-style aliasing distortion. When you start or stop any JACK app, the entire JACK graph structure gets re-ordered (this isn't true with jackdmp, just with single-processor JACK), and that causes the misbehaving app to start from scratch somewhat and get its audio organized properly. I'd suggest 64Studio, Musix, Pure::Dyne, or some other distro that has the really serious RT set up with the Ingo patches. With one of those distros, everything should run very well on a machine of any decent heft. -ken ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

[PD] A slightly more substantial question
I'm trying to create a PD application that'll be sync'ed to jack transport as a sort of master clock. I found the jack_transport object, loaded it, and it runs. If I bang it regularly with a metro, I can see the current sample in jack transport. So far so good. My question is about what'd be the most efficient/effective way to sync up a tabplay~ or tabread4~ object to the sample clock in jack transport. So far I've considered the following approaches: 1) Bang jack_transport with the output of a sig~ or phasor~ object, getting the clock from jack, and use that to hit tabread4~ (I don't know how I'd do this with tabplay~ though, and performance is an issue so if tabplay~ is cheaper I want to use it). 2) Bang jack_transport with the output of a metro every n milliseconds, and calculate what sample I'm supposed to be at in the tabread4~ or tabplay~ object, and just re-sync periodically if they drift. If they aren't ever going to drift (i.e. if PD's internal sample clock is sync'ed to JACK), then perhaps this resyncing will only happen at the start of playing, or perhaps I only need to do it then. 3) Or, maybe, let's say if I have a loop, I just need to bang the tabplay~ whenever the sample clock in jack_transport divided the number of samples in the loop is modulo 0. That'd be simplest and probably cheapest, but I don't know if the clocks will drift. Will they? I dunno. I'm asking you guys when probably I should be asking the software instead, by just trying it out and determining empirically what works. But before I get too deep into it I'd like to get a second opinion on whether any of the above approaches will work or if there's some other technique I should be looking at. For some reason I suspect that this'll go really easily, but I want to make sure I'm not overlooking anything important.

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 My MIDI controller is an M-Audio Axiom 49. It has 8 rotary controllers which can output continuous controller messages. This may be my way out of the 4-bit hole, and allow me to control parameters in PD with finer than 128 discreet steps. Are there any externals or internals in PD to handle these things? The Axiom manual states that each rotary controller can be configured in one of these ways: 2's complement from 64/Relative (Binary Offset) 2's Complement from 0 / relative (2's Complement) Sign Magnitude / Relative (Signed Bit) Sign Magnitude / Relative (Signed Bit 2) Single Value Increment/Decrement RPN Increment/Decrement Message NRPN Increment/Decrement Message I tried each of these and peeked at the MIDI stream to see what they do, and also at the output of PD's ctlin to see what might emerge. The sign magnitude and 2's complement ones look pretty promising: they indicate which direction (up/down) and how fast you spin the thing. Now, to turn those numbers into a float between -1 and 0 that I can use for controlling various parameters in PD. However, I'm getting old and lazy. I'm convinced that *someone* must have already solved this problem, and created an abstraction for using rotary controllers in PD. Google turned up hours worth of fascinating clicking, having nothing to do with what I was looking for. So if anyone can point me to an example patch or docs for using rotary controllers in any of the above formats, in PD,, please let me know. - -ken -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFG41SRe8HF+6xeOIcRAt2QAKDMF0MxlYPFrstiXI+glQVKfHiLawCg5PIc yR+zUNDl2UfVDwh35R3YBRw= =z2Am -END PGP SIGNATURE- ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

The command appears to be pd dsp 1;, which I'm now putting in all my patches. - -ken -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFG3D4be8HF+6xeOIcRAnDJAJ0SDaTHXNkpOERcXUN3PKFQLL/FHgCg3icW gzRi7XEmV82mklKlusBC+so= =k2V4 -END PGP SIGNATURE- ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

The JACK devices are definitely created at the time that PD starts up.

Only *then* will audio come out of any other patches that might be loaded, even if I can see from number boxes that the patches are definitely running. you hae to turn the audio-engine on in order to hear something. there is a little checkbox in the main pd-window that says compute audio, try enabling that... btw, this should be explained in the docs (if it is not, i think it is a serious omission) I didn't see it.

PS: i think it would be nicer to limit each email to just one (group of) question(s); as you can see by the answers so far, people seem to split it up anyhow, but the subjects and bureaucratic organization completely screws up. and pd-dev vs pd-list and... Thanks. I was looking for a pd-discuss list, and didn't find one, but I'll use pd-list from now on. - -ken -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFG21DEe8HF+6xeOIcRAnvUAJ4utNEpnMqg92nU9QeD8otSu8pwSQCcCUQ9 62cc0lO8EoGKC68xl/w8I2o= =2Xd1 -END PGP SIGNATURE- ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
