[linux-audio-user] Status of JACK midi sync?

by Ivica Ico Bukvic

Hi all, Any news on this one? IIRC, there was some talk that such a feature would be sponsored by Google's summer of code, but am not sure if this was the case or if anything ever became of it? Best wishes, Ico

[linux-audio-user] Vocoder Working

by DCZX

Okay, sorted out some file installation difficulties and now it's up! Pretty cool. I wonder if there's a program that can just "stick" a midi note for me though for the carrier... __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

[linux-audio-user] Miscellaneous hardware/software questions

by Jason White

I am looking for suitable hardware to handle digital i/o between a Linux system and an RME ADI-2 ad/da converter that I just bought. I don't need lots of channels, but reliability of the data transfer is important, including jitter reduction. An RME card would be excellent but it is somewhat outside my budget. Also, connectivity to a laptop would be desirable, suggesting either a USB interface or waiting until http://freebob.sourceforge.net/ (the Alsa firewire project) matures. I don't plan to run any OS besides Linux with this hardware, so Alsa support is crucial. As this is for home/personal use I'm not in a hurry. M-Audio hardware is high on my list of possibilities at the moment. Now to the software question: does there exist any sound editor with a non-graphical interface, i.e., one that can be operated from the Linux console for inserting, deleting, copying and otherwise editing audio? Due to a vision-related disability I can't use a graphical display and therefore need a text-only solution - but all the sound editors appear to require X11. Surely it should be possible to design an audio interface to a digital sound editor. Suggestions welcome. I've discussed hardware on this list once before, and the USB options weren't highly regarded at the time.

[linux-audio-user] Axiom 25 keyboard

by lanas

Folks, To complete my base audio setup I got a M-Audio Axiom 25 keyboard. The small size makes it easy to fiddle (no pun) around with apps using both the machine keyboard and this music keyboard at the same desk, without moving the chair. Getting it out of the box I noticed the paper about setting it up on Windows. About 10 steps in small print. Sheesh. And then me with Linux. Was I looking at a yet 3-day installfest ? Fortunately, not. I plugged the USB cable of the thing, started Jack, et voilá, it simply appeared and was ready to be connected to Zyn. One funny thing to add on this is that the Axiom documentation (which has nothing on Linux) troubleshooting section mentions that it can be that the keyboard at one point eventually stops working. In that case it is said that Windows users should re-install the driver. Well, you know, I still have to see the day when a Linux kernel module that is perfectly working stops to do so ! On with the question. I'd like to use the rotary knobs for interesting things such as changing some of the so many parameters of the Zyn synth. Is this possible ? Is it possible with another synth ? Anyone out there using those Axiom rotary knobs in creative ways ? And, is it possible to use the play/stop/backward/forward buttons with Ardour or MuSE ? Cheers, Al

[linux-audio-user] Linux audio sites on the www

by Mathias Friman

Hi list. In my quest for good audio related documentation for the Linux platform, several things strike me: 1. It is very scattered around the internet. 2. It has no unified structure 3. It is, in some cases, downright ugly. ;) Don't take this as critisism of webdesigning skills on a community wide basis, I know most of the people responsible for the websites have better things to do than to put days or weeks designing their content to please the eye. As everyone knows already, content is king and webdesign is for sissies. ;) However, a non-cluttered look and feel should make a newcomer more inclined to find what they seek, a link-farm of some sort would enable people to delve further into the world of linux audio and so on and so forth. It seems to me that most places throughout the Linux audio community are scattered like islands in a very big ocean with nothing to bridge them. I was thinking about a top row somewhat like the OSTG-bar on slashdot.org and the like, with maybe 6-10 of the most central sites in the linux audio community. Any rating of these sites will not be done by me, that's for sure. ;) The thought was to incorporate this bar on as many sites as possible, with a central link repository of some kind. How do you feel about such an idea? I'm willing to implement it, it there's any interest. Regards, Mathias

[linux-audio-user] VOIP and JACK

by Esben Stien

Just reporting on status of hooking up VOIP to JACK. I'm sure there are many wondering. I found twinkle softphone to work very well with oss2jack. (I'm on linux-2.6.18-rt1). Twinkle unfortunately does not separate the UI from the core, but it's the only piece of software I've found that works. I hope we can get the LAD VOIP channel up and running again. -- Esben Stien is b0ef@e s a http://www. s t n m irc://irc. b - i . e/%23contact sip:b0ef@ e e jid:b0ef@ n n

[linux-audio-user] Dave's Prelude

by Gavin Stevens

I must've downloaded Dave Phillips' Prelude a while ago & then not listened to it. Finally corrected that oversight & greatly enjoyed it - nice harmonies. In fact, a piece with a quiet, almost veiled beauty. I wonder if it would work on an acoustic piano (although it sounds nice with the bell piano)? Thanks Dave - I look forward to more. Gavin.

[linux-audio-user] Help me set the volume for Freebob, please!

by Carlo Capocasa

My Edirol FA-101 gives off a horrendous hiss during recording AND playback (well, most people probably wouldn't even notice it consciously, but I find it horrendous), and I have concluded it is probably due to the volume control being too low and me therefore having to jerk up the pre-amps and internal headphone amp (for which there are physical controls on the device) way higher than intended. So what I would like to do is simply turn up the volume to the highest sensible point for all channels and use jack applications to control the volume. I don't need a GUI or anything for this and this is a one time operation so PLEASE PLEASE PLEASE I BEG YOU don't make me go ask some friend with a Windows PC if I can install my driver on his device. I want linux power. I also want to go around showing people things they CAN'T do with their proprietary pieces of slavery. I'm used to compiling software, just give me a quick n dirty solution, any solution! Thank you. Carlo
