qjackctl and the hardware latency setting

by Maciej (Matchek) Bliziński

Hello list, I've come across a problem where the hardware latency numbers entered into qjackctl setup window don't take effect. I wrote up the details here: http://quinoa.blizinski.pl/~maciej/latency/calibration-problems.html The workaround was to start jackd from command line and pass the -I and -O options that way. It is possible (but not certain) that the problem was caused by qjackctl. I wrote a post on the qjackctl forum, but I'm not sure how much attention it gets. http://www.rncbc.org/drupal/node/749 Since my setup is fairly common components: Ubuntu 13.10 with ardour, jackd and qjackctl installed from packages, it sounds like I shouldn't be the only person to experience this problem. Has anyone else come across that? Maciej

QMidiArp 0.6.0 Initial release with LV2 plugins

by Frank Kober

QMidiArp 0.6.0 is out, since of course it cannot miss the huge TGV train of Q-Application updates just racing by for the new year! This release includes LV2 plugins of the three QMidiArp modules. They are synchronizable to the transport info provided by different hosts in different ways, and they work well with the new Qtractor, thanks to Rui for updates regarding this. I don't claim that I have fully understood LV2 host-GUI communication, but I found the recent sisco plugin by Robin Gareaus very instructive for this, thanks! Happy new year! Frank --------------------------------------- http://qmidiarp.sourceforge.net Direct download: http://sourceforge.net/projects/qmidiarp/files/qmidiarp/0.6.0/qmidiarp-0.6.… ---------------------------------------- qmidiarp-0.6.0 (2014-01-01) New Features o LV2 Plugins are now available for Arp, LFO and Seq modules - They have full functionality as known from the standalone application except MIDI control, which can be provided by the host - The LFO plugin also has a LV2 control output scaled from 0 to 1 - When the 'Sync to host' option is checked, the plugins support transport LV2 atom data from hosts as well as host transport information available from designated lv2 time ports (Qtractor, thanks Rui!) - Arp pattern presets are available in the LV2 module but cannot be written to the .qmidiarprc file. This has to be done with the standalone application - On hosts with small atom port capacities that do not honor the lv2 rsz:MinimumSize property, there will be issues with displaying very large LFO waveforms - Features of QMidiArp beyond the modules themselves (including global storage) are not available Fixed Bugs o Trying to open an inexistent file from the recent files menu led to crash (reported by Frank Neumann)

pygtk jalv starter

by hermann meyer

Hi I've reworked my little pygtk script to select a plugin and run it with a selected jalv interpreter. It use now python-lilv to create a plugin-list. You can select the plugs now by name, and you can search the list by regex to find a plug fast. https://github.com/brummer10/jalv_select greetings hermann

'Reverse' gates?

by Andrew C

Hello everyone, Is there a ladspa plugin that is a 'reverse' gate of sorts? i.e removing noises louder than a certain db, but keeping quieter ones? Or do I need just have to learn how to use gates properly? Thanks! Andrew.

No sound with jack

by Peter O'Doherty

Hi, I've just installed qjackctl and am having trouble with the audio setup in a few programs (like pd, supercollider). When I run these programs I get no sound and also no error messages in qjackctl. Is there a way to test whether jack is working correctly? Here is my setup: Ubuntu 13.04 qjackctl 0.3.10 libjack-jackd2-0 libjack-jackd2-dev Any help would be greatly appreciated. Thanks, Peter -- //============================= -> Peter O'Doherty -> http://www.peterodoherty.net -> mail(a)peterodoherty.net //=============================

Midi program change in Muse

by Brent Busby

Does anyone happen to know how to insert a Midi program change command in mid-sequence in Muse? If I bring up the piano roll editor to edit a region, there is a tool at the bottom under "ctrl" to insert things, including program numbers, but anything I put there changes the global program number for the whole track, and is seen in the main window as the new program for that track's whole timeline. I'm sure there's got to be a way to put a program change command into the middle of the track timeline, isn't there? -- + Brent A.
