KMidimon 0.5.1 released, KMetronome and kaseq also updated.

by Pedro Lopez-Cabanillas

Hi, KMidimon is a MIDI monitor for Linux using ALSA sequencer and KDE 3 user interface. Temporary web site: http://kmetronome.sourceforge.net/kmidimon/ KMetronome is a MIDI metronome with KDE 3 interface, based on the ALSA sequencer. Web site: http://kmetronome.sourceforge.net ALSA MIDI Kommander is a DCOP interface exposing ALSA Sequencer services for shell scripts, Kommander scripts or programs. Temporary web site: http://kmetronome.sourceforge.net/kaseq/ The three applications are licensed under the GPLv2. New releases available: KMidimon - 0.5.1 KMetronome - 0.8.2 ALSA MIDI Kommander - 0.3.1 The common motivation of the releases is the fix of a crash that happened when using the program when ALSA was not loaded. They show now a message box giving the user some clues about how to fix the problem. The documentation has been updated as well. Download the source tarballs from: https://sourceforge.net/project/showfiles.php?group_id=134956 Regards, Pedro

Dirk By the way, I like the introduction videos at the website of freewheeling. Something which more linux apps websites should have!! :)

electric piano

by schoappied

Hi, This is just a question to get a idea of the possibilities... Can I use a electric piano the same way as a midi keyboard? Playing other instruments on the piano using midi etc.? What kind of other software do I need? Dirk

Call for Student Participation - CLAM in Google Summer of Code 2008

by Pau Arumí

We are glad to announce that 2008 summer is also going to be a Summer of Code for CLAM [1]. In other words, CLAM has been accepted as a mentoring organization for the Google Summer of Code, a program that offers student developers stipends of 4500 USD to write code for open source projects [2]. We are looking for smart students who enjoy coding free software so that they can earn some bucks for the summer. Last year, GSoC 2007[3] was a very fun and productive experience and we are willing to repeat it. Take a look at the CLAM GSoC 2008 wiki page[4] for more information on how to apply and some sample ideas[5] for projects. CLAM (C++ Library for Audio and Music) is a framework for research and applications development in the audio domain. It offers a multi-rate dataflow model suited for spectral processing, and a visual building tool that allows to develop rapid prototypes without writing code. See the CLAM web for more details and screenshots. We are waiting for you! Application deadline: March 31 If you have any question about any of the information below please contact ask to clam-devel list or join the #clam channel at FreeNode IRC. [1] http://code.google.com/soc/2008/clam/about.html [2] GSoC FAQ: http://code.google.com/opensource/gsoc/2008/faqs.html [3] http://iua-share.upf.edu/wikis/clam/index.php/GSoC_2007 [4] http://iua-share.upf.edu/wikis/clam/index.php/GSoC_2008 [5] http://iua-share.upf.edu/wikis/clam/index.php/SoC_ideas

Jack problems on Dell M90

by Nathanael Anderson

I'm hoping I'll be able to find someone else with a similar setup that has overcome their problems to get realtime operation, at least in one direction, with no xruns. Setup: Dell M90 (intel-hda audio) Kernel 2.6.24 RT PREMPT SMP from gentoo pro-audio feed quadro 1500fx with nvidia driver (i'd really like to keep this driver, unless compiz works now with the nv driver) I've tried multiple combinations of: irqpoll noacpi noapic pci=biosirq, some combinations help to reduce latency, but not enough to be useable I have GNX4 Guitar interface that works as a usb device, its almost useable with the same settings the intel-hda card skips with. I have an Opteron with sb-live that no no latency problems, and the GNX4 works great with it. What suggestions for Frames/Period, Sample Rate, Periods/Buffer would people reccomend to make this useable. I really just want to be able to mix and output audio in realtime on my laptop with its intel-hda card, full duples with the GNX4 on it would be an added bonus. If anyone is willing to look over the kernel config I can send them It, didn't want to clutter the list with it now. cat /proc/interrupts CPU0 CPU1 0: 20489426 0 XT-PIC-XT timer 1: 14552 0 XT-PIC-XT i8042 2: 0 0 XT-PIC-XT cascade 5: 0 0 XT-PIC-XT uhci_hcd:usb4 7: 2008 0 XT-PIC-XT ipw3945 8: 2 0 XT-PIC-XT rtc 9: 2930465 0 XT-PIC-XT acpi, uhci_hcd:usb3, nvidia 10: 269 0 XT-PIC-XT uhci_hcd:usb1, ehci_hcd:usb5 11: 1627576 0 XT-PIC-XT uhci_hcd:usb2, HDA Intel 12: 16281 0 XT-PIC-XT i8042 14: 60131 0 XT-PIC-XT libata 15: 64207 0 XT-PIC-XT libata 218: 1624641 0 PCI-MSI-edge eth0 NMI: 0 0 Non-maskable interrupts LOC: 5672972 14563710 Local timer interrupts RES: 9766464 13228888 Rescheduling interrupts CAL: 46404 41727 function call interrupts TLB: 21123 35433 TLB shootdowns TRM: 0 0 Thermal event interrupts SPU: 0 0 Spurious interrupts ERR: 0 MIS: 0 Thanks in advance, Nathanael

[ANN] Snd-Rt homepage update, Snd-ls V0.9.8.13 and jack_capture V0.9.7

by Kjetil S. Matheussen

Snd-Rt ====== Snd-rt is a realtime music programming environment running inside the Snd sound editor. The homepage has been updated with links, papers and many examples on how to create GUI's and how to access Faust. The old fancy design is still kept unchanged. http://www.notam02.no/arkiv/doc/snd-rt/ Snd-ls V0.9.8.13 ================ Snd-ls is a distribution of Bill Schottstaedt's sound editor SND. (http://ccrma.stanford.edu/software/snd/) Its target is people that don't know scheme very well, and don't want to spend too much time configuring Snd. It can also serve as a quick introduction to Snd and how it can be set up. Snd-ls also serves as base code for the San-Dysth softsynth (http://www.notam02.no/~kjetism/sandysth/) and the Snd-rt music programming language (http://www.notam02.no/arkiv/doc/snd-rt) http://www.notam02.no/arkiv/src/snd/ Changes 0.9.8.5 -> 0.9.8.13 --------------------------- -Updated Snd-Rt. (unguote-splicing, gui) -Updated Snd-Rt. (gui, dynamic scoping, oscil* etc.) -Updated Snd-Rt. (timer) -Updated Snd-Rt. (timer, faust, definstrument) -Updated Snd-Rt. Faust support. -Fixed rt timer. Previously it only ran 3 hours before giving negative numbers. Now it should run approx. 13 million years. (not tested) -Removed access to removed functions in jack. -Updated eval-c.scm. jack_capture ============ jack_capture is a program for recording soundfiles with jack. Its default operation is to capture whatever sound is going out to your speakers into a file. (But it can do a number of other operations as well...) http://www.notam02.no/arkiv/src/ 0.9.6 -> 0.9.7: *Don't segfault if the opening of a subsequent wav soundfile fails. (ie. if the 4GB limitation is reached on the old file and jack_capture continues writing on a new file.)
