[linux-audio-user] Does anyone have a working example of Supercollider and SCUM GUI where slider or a button does real-time update on the synth

by Ivica Bukvic

Greetings all, I guess title says it all. I do have working examples (i.e. the sequencer example from the LAD 2004) that make new instances of synths but none of them actually do real-time updates to existing instances. At any rate I would greatly appreciate your help in this matter. This is as far as I got and cannot figure it out beyond this point (my brain is pretty darn fried :-): s = Server.local.boot; SynthDef("onetwoonetwo",{ arg out=0, freq; w = SCUMWindow.new; w.title = "Slider example"; w.initialSize = Size(20, 300); c = SCUMVBox( w ); v = SCUMSlider(c, { |v| v.expand = 1; v.fill = 1; v.bgColor = Color.white; v.fgColor = Color.black; v.action = { freq = v.value * 100; }; v.doAction; }); w.show; Out.ar(out, SinOsc.ar(freq + 400, 0, 0.5) ) }).play; What I am simply trying to do is to affect the frequency of the sinetone by moving the slider, yet nothing changes when I move the slider. Any help would be greatly appreciated! Best wishes, Ico

[linux-audio-user] music [some more]

by Florian Schmidt

Hi, this is just me playing around with a loop: http://affenbande.org/~tapas/om1_2.ogg i'd call the style abstract dopehead-dub-reggae. As you can tell from the name the main software involved was om-synth. but i also used qsynth, seq24, jack-rack and jack_convolve. Have fun! Flo P.S.: The .ogg is very quiet, as jamin likes to segfault atm (might be the result of shoving a different jackversion beneath it), so no mastering done.. -- Palimm Palimm! http://affenbande.org/~tapas/

[linux-audio-user] search programm: audio recording with adjustable start / stop level

by Ruben Jenster

Hi, I want to archive very much LPs. Therefore I search a programm that is able to start / stop the recording dependent from the input level. The time period of the input level that triggers the recording to start/stop should be adjustable (or very long - to avoid stop recording in silent passages of a sond). It would be very good if the programm can send a event, or execute a programm if it stops recording because I want to automate the splitting and encoding process after the recording has stopped. Does anyone knows a (set of) programm(s) that can do this job? Regards Ruben

I have an old Roland Gr-50 with a GK-2 midi pickup. I have used it live a lot. In that case my main use was to fill in string beds underneath normal guitar comping. I also had a handful of percussive patches that I mixed with the natural guitar sound. Occasionally I used an organ patch or keyboard sound when I was gigging without a keyboard player. I liked it for what it was. I am just getting used to it again in this new linux recording enviroment. You do have to play differently to use it, but I think that should be an expectation anyway. I have my pickup on my strat which seemed to work better for midi but is not nearly as playable a guitar for me as my Howard Roberts Artist. As a result I have a little more difficulty controlling attack. You can hear this in the bass in this little practice recording I did last night to get ready for an upcoming jazz gig. The bass was recorded in one take with no edits or effects played on the strat with ardour recording fluidsynth and a sonic implant sound font. Hopefully you can hear the point of this which is to practice, not to create great music ;-) http://blogs.xcskiwinn.org//images/blogs_xcskiwinn_org/panmanphil/5/r_2295-… Philip - http://blogs.xcskiwinn.org/panmanphil "There's a difference between righteous anger and just being crabby" - Barbara

Thanks. I've looked at the midi transform tool in muse... it does *some* of the things I want. Perhaps I should look at adding some sort of scripting to muse to do the rest. It would be nice to make use of an existing framework and to be able to do things inside an existing editor rather than doing the "save to midi file, run some program, reload the midi file" thing. > > The second part is harder, where you talk about the "music view" in notes, > beats, bars vs the data view.

Audacity can send audio data to nyquist and nyquist can handle both audio and midi data, so I guess hacking on audacity is another possibility. Audacity loads and displays midi data but doesn't play it or (AFAIK) pass it to nyquist yet. I guess I'm looking for a scriptable midi editor similar to the way in which, say, "snd" is a scriptable audio editor. Thanks for the comments Philip. BTW, I noticed your comment in another thread about having a guitar midi controller. Which controller do you have? Does it track well enough to be useful? I'd love to get into midi guitar, but I'm not sure where the current state of hardware/software pitch tracking is. Any comments you have would be useful. Cheers, Stuart

Some of these operations should be easy to do with scripts. The difficult part is to process SMF files. I recommend you to first convert the MIDI files into text, and then process the text using Perl or Python. Here are several tools for text-based MIDI processing: http://alsa.opensrc.org/index.php?page=MidiComp Regards, Pedro

[linux-audio-user] More Homemade Muzak

by Steve D

--Just some more original music from a list member, for anyone who is so bored they can't think of anything better to do. I'm recovering from the flu, so I went for the easiest, least fussy recording route this time. I just played the three keyboard parts straight through my M-Audio Delta 1010 sound card into Audacity, using it like a digital multitrack. No MIDI, no editing except for trimming the beginning and ending silence and adjusting the relative volumes of the three tracks.

I meant that the program has logic to relate the note on event offsets to bars, beats etc so the track editor can function.
