A classic needs no introduction. QjackCtl 0.3.5 slipped away!

Change-log: - Late support for UTF-8 encoded client/port names. - Allow only one single patchbay connection to or from an exclusive socket (mitigating bug #2859119). - Automatic crash-dump reports, debugger stack-traces (gdb), back-traces, whatever, are being introduced as a brand new configure option (--enable-stacktrace) and default enabled on debug build targets (--enable-debug). - Probable fix on the audio connections with regard to client/port (re)name changes (an ancient bug reported by Fons Adriaensen). - Portaudio device selector is now available (after a patch handed by Torben Hohn and Stephane Letz). - A couple of primitive D-Bus interface slots have been introduced, giving the option to start/stop the jackd server from the system bus eg. via dbus-send --system / org.rncbc.qjackctl.start (.stop), (a nice addition supplied by Robin Gareus, thanks). - New command line option (-a, --active-patchbay=[path]) to specify and activate a given patchbay definition file (a simple patch sent by John Schneiderman, thanks). - Added one significant digit to DSP Load percentage status display. - Tentative support for netjack (slave) by adding the "net" driver to the existing backend driver options on the Setup/Settings section. - Converted obsolete QMessageBox forms to standard buttons. - New patchbay snapshot now raises the dirty flag and allows for the immediate salvage of patchbay definition profile. - Conditional build for JACK port aliases support (JACK >= 0.109.2). - Alternate icon sizes other than default 16x16, are now effective to the Connections widget (Setup/Dislay/Connections Window/Icon size). Enjoy, -- rncbc aka Rui Nuno Capela rncbc at rncbc dot org http://www.rncbc.org

jack-rack feature request

by Renato

Hello, I've sent this email in July on the jack-rack-devel list but haven't got response... I'm posting it here in the hope of some dev to take up this idea, which IMHO is really missing from jack-rack and would take it a step further. [jack-rack-devel] feature request: preset change through midi From: Renato Budinich <rennabh@gm...> - 2009-07-17 08:37 hello, It would be great if it were possible to browse saved presets from a separate window, and sending midi program changes to go up or down the list. (the window is actually a detail, what i think is really missing is the possibility to change presets from say a pedal board if one is occupied playing an instrument) for the rest i think jack-rack is great! Great midi implementation Renato

FFADO Contact Needed

by alex tinsley

Hi, I have tried the contact form on the FFADO website and through the email address provided in the contact pages at the SourceForge.net project page to no avail. I'm not sure where else to ask except here. Are any of the FFADO developers on this email group that can provide a contact email that will garner a response? Thanks, Alex -- When you gotta have it, you gotta have it. Lesson learned from days of record shopping.

"Open midi-keyboard"

by Albin Stigo

Hi, I'm new to the list so I hope this is not the wrong forum! I've been working on a midi keyboard ("physical" hardware 88-keys "professional" = no toy) for a while for which I plan to release the schematics and source as open source. It's based around a Fatar keybed (they make Studiologic) and an Atmel AVR mcu. The code is all in C and is very portable. Current features are: - Velocity sensitivity. - Pedal support. - Custom velocity curves. - Only normal MIDI serial "current" link. No USB, yet... My questions are, Is there an interest in this sort of thing..? What features would you like to see, what are you missing from off-the-shelf products? Atb, Albin

SC-AU-VST wrapping

by Paul Jones

Hello everyone, I'm new to this list. My names Paul, I'm developing a plugin in Supercollider. It allows a user to define algorithmic processes using a GUI and trigger them via MIDI. I have the following question, how does one go about making this available cross platform as an AU instrument or VST instrument? It should suffice in the first instance to just receive midi note triggers. Thanks for any pointers Paul Send instant messages to your online friends http://uk.messenger.yahoo.com

alsa and buffer size

by Vincent Meserette

Hi all, I'm trying to use alsa with a buffer size other than a power of two for capture. If a define a buffer size of 8000 in my /etc/asound.conf file and if I use arecord it works, but if I try to access to the samples in my code with the snd_pcm_readi function and this size of buffer I have an EPIPE error. Does anyone know from where could comes the problem ? Thanks in advance Vincent

Re: [LAD] Non-daw, non-sequencer (fork?)

But am > incredibly busy at the moment. Danni, That would be cool! I posted this cause it will be a lost for Linux Audio if this dies imho. Btw I think I found one disadvantage in the workflow of non-sequencer. You can choose a scale to work in, but the disadvantage afaik is that you can't choose notes outsides that scale. Maybe I'm wrong, but if I'm right it seems to narrow the possibilities quite a bit. \r
