music made with linux - Wanda & Nova deViator - Pacification

by Luka Prinčič / Nova deViator

hi all, just wanted to let you know, that myself and Wanda 'officially' released an album on our own little label Kamizdat in early April. some of you may have seen us on LAC in Utrecht and in Ireland. well, the album was made almost entirely on linux (i had a collaborator at the end who did mixing and mastering, who was not on linux). anyway, it's a free download (name your price - can be 0) on bandcamp: http://kamizdat.bandcamp.com or you can order CDr, and special handmade boxed limited editions with USB or CDr. best, Luka -- Luka Prinčič / Nova deViator - + 386-40-66-77-98 + http://deviator.si + D6A4 595B F092 684A 389E CD9D 1397 C721 FFA5 2FD7 -

no sound in ubuntu studio 13.04

by architectadrian

I installed Ubuntu Studio 13.04 and have no sound. I reinstalled the system due to some video card errors I could not bypass after an upgrade from Ubuntu Studio 12.10, but on the old system the sound (and video) was working. The only thing I had was a sound from the microphone, after I unmuted it in alsamixer. No other playing or recording was available. Can anyone help me with this? I wouldn't like to go back to 12.10, install all programs and updates again. Thank you. -- View this message in context: http://linux-audio.4202.n7.nabble.com/no-sound-in-ubuntu-studio-13-04-tp847… Sent from the linux-audio-user mailing list archive at Nabble.com.

a2jmidid/aj-snapshot issue

by Ralf Mardorf

Hi :) I start my sessions by scripts, I don't use session managers. "a2jmidid -e" could cause issues for aj-snapshot regarding to ... Connecting port 'a2j:Qtractor [136] (capture): Master' with 'yoshimi:midi in' Connecting port 'a2j:Qtractor [136] (capture): Master' with 'yoshimi-01:midi in' ... ^^^, most of the times it's ok, but it doesn't work always. No drama in this case, but it could become unfunny, if there would be more connections, since this number isn't always the same. If I don't need all cards, I could run "a2jmidid -eu", IIUC it would drop this ID, but if I want to use my Envy24 cards too, then ... port created: RME AIO_579bcc [16] (capture): HDSPMx579bcc MIDI 1 port created: RME AIO_579bcc [16] (playback): HDSPMx579bcc MIDI 1 port created: TerraTec EWX24/96 [20] (capture): TerraTec EWX24/96 MIDI port created: TerraTec EWX24/96 [20] (playback): TerraTec EWX24/96 MIDI port created: TerraTec EWX24/96 [24] (capture): TerraTec EWX24/96 MIDI port created: TerraTec EWX24/96 [24] (playback): TerraTec EWX24/96 MIDI I can't use the -u switch, because it would cause ...

It would be possible to ask for the ID and then let the script edit the file that will be used by aj-snapshot, before it runs aj-snapshot, but IMO this is another bad extra effort.

Probably not PA, and besides you have tried with PA turned off. Pa was having problems about that time, but normally the problem was after having used it to stream.

I have tried Cadence and it has a lot of different ways of doing things. You do have both jackd and jackdbus. Both Cadence and qjackctl are able to deal with either one. However some of the jack apps will start jackd if no jack is running. So if an app starts jackd and then you use qjackctl (for example) to start jackdbus, it will fail because the device is already in use. So maybe try: jack_control exit kill -9 jackd and see if jack starts. When you have this problem. Really, these are shots in the dark. I am trying to think what questions to ask that could narrow things down. -- Len Ovens www.OvenWerks.net

About the Functional Transformation Method of sound synthesis

by Yvonnick Noel

Hello all, In the line of my previous post about lv2_guitar, I wondered if anyone ever tried to implement the Functional Transformation Method of sound synthesis in an open source softsynth. This would allow for all parameter adjustments, as described in: http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.84.1572 An implementation is described in: http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.10.6022 I must say that I know nothing about filter theory and would be totally unable to do write such a program myself, but maybe one of the signal theory gurus around here could have a look... :-) Best, Yvonnick

Are you running an audio or video player? Have you been using a web browser that was seeing a video or just hit a page with video adds? To put it another way, does this problem show up right after a fresh login? or only after having used the system for a while. What does your desktop use for most of it's non-jack audio output? -- Len Ovens www.OvenWerks.net
