For example, Csound has script UI because that is all what is there. If PD can be fully programmed via text files, then it has script UI. A script support is not exactly the same thing as script UI if user has to use GUI at some point. Maybe "text UI" would be better than "script UI". Regards, Juhana

[linux-audio-dev] Vsound-like tools for ALSA?

by Tom Felker

Hi, Are there tools to copy audio to a file as it goes through ALSA to the soundcard? I'm basically looking for something like VSound, but for everything, not just apps that can be coaxed to use OSS. If not, would there be a way to implement such a tool without resorting to vsound-style LD_PRELOAD hacks? Thanks, -- Tom Felker, <tcfelker(a)mtco.com> <http://vlevel.sourceforge.net> - Stop fiddling with the volume knob.

[linux-audio-dev] [ANN] new LADSPA plugins

by Tom Szilagyi

Hi all, TAP (Tom's Audio Plugins) 0.1-0 is released. Currently four LADSPA plugins are available. You can check them out at: http://www.hszk.bme.hu/~st444/tap/tap.html Key features: * TAP Equalizer 8 channel equalizer with adjustable band center frequencies. * TAP Reverberator Actually no less than 38 reverberator effects, ranging from Afterburn to Warehouse, including small/medium/large rooms, halls, plates... and more! * TAP Stereo Echo Supports conventional mono and stereo delays, ping-pong (cross) delays and the Haas effect. * TAP Tremolo The newest incarnation of an ancient effect. The plugins have been developed and tested primarily with Ardour as a host in mind, but should be functional with any LADSPA-capable host. A thorough manual is provided in HTML format, including detailed information, CPU usage metrics, usage tips & more about each plugin. Enjoy! Tom Szilagyi

[linux-audio-dev] ".mid" files playing in Linux games

by Dominic Genest

Hello, I am programming some little games in Linux as a hobby, and I composed midi files that I would like to be played in the background. What is the easiest way to do this so that it works on all platforms for everyone ? I would like suggestions of real time synthesizers that can read ".mid" files. Does anybody know of any library that just does all the work to send wave output to sound cards from a ".mid" file ? Also, I would like not to have to supply instrument files. Thanks a lot for any answer or clue ! Dom -- Dominic Genest Étudiant 3e cycle Département d'Informatique et de Génie Logiciel Université Laval 97010111

[linux-audio-dev] Ann: Specimen v0.1.0 (the first beta release)

by Pete Bessman

Too everyone who's waited with bated breath for this day to come (primarily me), rejoice in the first beta release of Specimen, a midi controlled audio sampler for GNU/Linux systems. Features as listed on the webpage: # ALSA sequencer interface support. # Audio output via ALSA or JACK. # Individual panning and volume controls for each patch. # High quality cubically interpolated pitch scaling. # Sample start/stop and loop points. # Three playback modes; "normal" just plays the sample, "trim" plays the sample and stops early if so instructed, "loop" plays the sample for the requested duration. # Patch bank saving and loading in the "beef" file format. Check out www.gazuga.net for more and to download the source. I'm gonna spend the next few days giving the program a usability test and creating a demo song that does it justice, so keep your ears open for some homegrown UHB in the not-too-distant future. [pb]

Re: [linux-audio-dev] creamcheese

by James W. Morris

creamcheese... little bit twee, perhaps, but, nice and pleasant, definately category C for chilled, reminded me of aphex twins rarer chilled moments. I liked it. But the ending , suffered a little from what I've come up against when I've done tracks, and thats not quite knowing how to end it? leaving it slightly unresolved sounding. But that's after just one listen, so don't take what I say too seriously ;) jwm ~(sirromseventyfive)~ >Would this (http://dis-dot-dat.net/creamcheese.mp3) do for b or c? >The call seems to want classical for category b, so probably c would >fit best. > >If anyone else would like to have a listen, I'd appreciate that very >much.

[linux-audio-dev] Lionstracs Mediastation, LinuxSampler, Linux at NAMM

by Benno Senoner

Hi, just back from NAMM, just a few infos for the interested people: Lionstracs had a booth demoing a preliminary version of the Mediastation X-76 ( http://www.lionstracs.com ) I've read a thread here about people complaining about the price of the keyboard. ( $12,000). I fully agree, the problem was the distributor trying to ask an exaggerated price. Too many men in the middle (distributor, retailer) each one wants a big cut of the pie while the producer of the actual iron usually earns only a fraction of the price the user pays. But you know since the distributor hosted Lionstracs at his booth you cannot complain about the price they want to set :-) Anyway see Domenico's (Lionstracs head) posting: http://www.lionstracs.com/index.php?name=PNphpBB2&file=viewtopic&t=7 the new price will be around $6200 which is much more in line with current keyboards. AFAIK: Korg's flagship the PA X-Pro is about $4500, add mp3 playback expansion, sample RAM expansion (from 16MB to 32MB :-) ) and you get into the $5000 - $5500 which is comparable to the Mediastation X-76 price but the X-76 much more iron (256 DSP voices vs 64, 512MB sample RAM vs 48MB sample ROM, not to mention what you can do in software with the Athlon 2400+ CPU (LinuxSampler, softsynths, ardour etc). Anyway if you want to see a couple of videos of the Mediastation X-76 in action (with crappy audio since it was taken with a camcorder in the noisy NAMM halls): (the guys were playing the keyboard over an mp3/wav song that ran in the background, changing the sounds interactively (mostly by pressing one single button , eg organ family, and then select organ patch) You can play them with mplayer/xine too but I think you need the win32 codecs installed. Length: 2:22 size 23MB http://www.lionstracs.com/~demos/video/x76smooth1.AVI Length: 4:58 size 48MB http://www.lionstracs.com/~demos/video/x76delmar1.AVI (The GUI at 3:00 in the second video is Paul Davis that tells the keyboarder to shut up with his 120dB noise :-) ) Domenico told me probably they will sell individual parts too so people can build their own keyboard without paying an arm and a leg. (eg case + MIDI keys + LCD , custom VGA with Linux supported GFX chip etc) As said this company tries to be open as possible and its success depends on the success of linux audio too, so I think it's in their interest to support LAD people. For example developers could get discounted keyboards in exchange of code etc, there are many possibilities. Domenico is in talks with Mathias Nagorni about coming at the upcoming ZKM with a Mediastation to show it off and that he can meet developers offer some paid work for developing new apps (or adapt existing ones) for the keyboard etc. BTW: many top engineers of the big 3 keyboards makers came to see the X-76, seemed quite puzzled that a penguin-powered keyboard exists :-) regarding LinuxSampler & NAMM read this: http://sourceforge.net/mailarchive/forum.php?thread_id=3758500&forum_id=127… I was quite surprised about the positive reaction. Other Linux stuff was Plugzilla, a hw expander (a Linux PC) that runs VST plugins (I've meet Marc Lindahl and Joe, very nice people), then there was the Muse Research box which is AFAIK similar to Plugzilla and the Hartmann Neuron was there too but I have not had the time to chat with them. (it is linux powered too but they don't tell you so on their website). ok shutting up :-) cheers, Benno http://www.linuxsampler.org

[linux-audio-dev] TAP plugins (follow-up)

by Tom Szilagyi

First of all, a big thank-you goes to Steve Harris for checking my RDF. Second, tap-0.2.0 is out: * New plugin TAP Scaling Limiter This should be an efficient tool for those who want to maximize the loudness of their mixes without audible artifacts, but can be used for other things as well * Added a Bode diagram of the TAP Equalizer filters to the manual. * Changed versioning from x.y-z to x.y.z. Thanks to Frank Barknecht and others for complaining, and sorry I wasn't aware of this problem. The almost but not completely unmemorizable URL is still: http://www.hszk.bme.hu/~st444/tap/tap.html (but i'm thinking about whether i should put it up on SourceForge...) Tom
