On Debian Sid, something seems to have installed systemd-logind (or something else?) and now when I start JACKD, it reports "Cannot use real-time scheduling (RR/10)(1: Operation not permitted)". I am a member of the audio group. ISTRC folk on the list mentioning what to do to get RT permission back? -- David W.

[LAU] User Documentation

by Will Godfrey

Come on now, don't all run away :) What do people think would be the best format (from a user's point of view), yet reasonably easy both to transfer and to keep up-to-date? -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.

[LAU] Fireface UFX in class compliant mode

by Peter P.

Hi list, not sure if this has been reported already, but today I was able to connect an RME Fireface UFX in class compliant mode via USB to my Debian box and got 22 Channels (the limit in RME's class compliant mode) of output working (was not able to verify inputs due to a lack of real-world input sources) with Pure Data and ALSA's OSS emulation, as well as with jack. Most likely it does not make sense to purchase such an exquisite audio interface for use with linux, as the mixing application will not be accessible from software, and with it most DSP processing power in RME's on-board mixer. But in case your institution/department chair/infrastructure management decided to buy such a thing, and you see it sitting unused on a shelf in someone's office, i thought it might be nice to know you can get at least 22 I/O with it on a standard Debian testing box via USB 2.0 best, Peter

[LAU] [ANN] Qtractor 0.6.7 - The Lepton Acid beta release!

by Rui Nuno Capela

It's alive! Qtractor 0.6.7 (lepton acid beta) is out! Release highlights: * MIDI instrument rendering on audio export (NEW) * MIDI clip editor view/event criteria persistence (NEW) * MIDI clip editor resilience on record/overdub (FIX) * Generic plugin form position persistence (NEW) * JACK Transport/Timebase master option (NEW) and yet more tiny lurking critters swatted ;) Well, the major highlight to this release is in fact this brand new and way long overdue feature, seamlessly integrated to the faithful and regular audio track export function: MIDI track instrument plug-in rendering and mix-down (aka. freeze) is now real, as long their audio output goes onto selected buses, aka. stems, mix-groups, whatever a mix/mastering head would name it! nb. on the (very esquisite) Qtractor arch-model parlance, those are just called "audio output buses" and that ain't gonna change, any time soon, so stop it! A word of caution must be told by now: dedicated (JACK) audio output ports are off-the-grid, so sorry. Maybe this silently makes a notch towards the DAW epitome, though Qtractor still claims to be just a plain and honest sequencer--with yet another DAW-like feature addition--the same as it ever was. Nuff said. Qtractor [1] is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework [2]. Target platform is Linux, where the Jack Audio Connection Kit (JACK [3]) for audio and the Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.

Change-log: - MIDI clip editor (aka. piano-roll) position, size, and view/event type criteria are now persistent, across session and user preferences application state. - Generic plugin form widget position is now also preserved across open/save session cycles. - MIDI clip editor resilience is about to get an improvement, fe. it doesn't close on stopping record/overdub anymore. - Introducing (JACK) Timebase master setting as an option to Transport mode (cf. View/Options.../General/Transport/Timebase). - LV2 plug-in MIDI/Event support now slanted for deprecation. - Spanish (es) translation added, by avid Reyes Pucheta. - It's live: audio track export (cf. Track/Export Tracks/Audio...) has been deeply refactored to finally include MIDI track/instrument plugins rendering (aka. freeze) on selected audio output buses on mix-down. (EXPERIMENTAL) - MIDI file player now does (N)RPN 14-bit controller events. - Track properties dialog output bus switch fix/optimization; also fixed multiple DSSI instance reference count on close. - Fixed for some strict tests for Qt4 vs. Qt5 configure builds. - German (de) translation update (by Guido Scholz, thanks).

[LAU] PCI1 and new motherboards - a tip

by Jostein Chr. Andersen

Hi, I'm in the process of upgrading my computer HW, but still want to use my old trusted M-Audio delta 1010 cards. Two times, I have had to buy a motherboard with old PCI ports, or that is what I have believed for some years. Today I found this on the 'Net: http://www.startech.com/Cards-Adapters/Slot-Extension/PCI-Express-to-PCI-Ad… ..and will probably find more if I dig further. After overlooking this kind of solutions for years, and also seeing this topic coming up at this list for years, I feel a little stupid. :-) I know that many of you still have PCI1 state of the art cards of different kinds and I hope that this solution will work for yo if you consider to upgrade your computer HW.

The drums on Cold Drop are from one of Bitwig's 707 kits. The basses were played by u-he's Triple Cheese via Airwave and Iain McCurdy's FMClang Cabbage instrument plugin. dp

[LAU] Experience with rpi, wolfson audio card and JACK

by F. Silvain

Hey hey everyone, has anyone tried the Wolfson audio card with JACK yet? It's a little difficult to find, since google doesn't distinguish between jack and JACK. :) A link to a relevant post somewhere will suffice. Thank you!

[LAU] GuitarSynth now as lv2

by Gerald

Hi, GuitarSynth is now an lv2 plugin. Yep, it's true, thanks to falktx's DPF. You can get it at https://github.com/geraldmwangi/GuitarSynth-DPF. A new feature is the Overlay Input: It multiplies the synth output with the input signal frame by frame. Basically this results in the convolution of the frequency spectrum of the synth with that of the input. Have fun testing it and give me your thoughts. this was announced previously under the subject Jimson Drifts double attack. I guess no one looked at it since the subject says nothing. Sorry for that. Regards, Gerald
