Hello dear linux audio users, Having read threads about harmonySEQ, i decided to try it, then to package it for ubuntu 14.04 as it is not included in the official repository. As i also tested qtractor 0.6.0, i packaged it as well since official ubuntu repository offers an older version. I read the ubuntu packaging guide online, and finally succeed to submit these two source packages on my launchpad personal package archive. I thought these packages would be useful for some of you too if you are a ubuntu user. These 14.04-only packages should be OK to install on any ubuntu 'trusty' flavour. If you like qtractor or harmonyseq, and use the latest ubuntu, you may be interested in adding the PPA into your APT configuration. See details on 'howto' here: https://launchpad.net/~brouits/+archive/ppa Actually, its just a matter of blind typing 3 comands in a terminal: $ sudo add-apt-repository ppa:brouits/ppa $ sudo apt-get update $ sudo apt-get install harmonyseq qtractor (do not type the '$') These _unofficial_ packages have been built for both 64bit and 32bit Intel platform. But BEWARE, these packages are for ubuntu _14.04_ only. Do not install them on an older ubuntu version. If you have an older ubuntu, you might want the source package: i can give you so that you can build it on your version.. if it works. Qtractor has been compiled _without_ Windows VST support (cause i do not have the Steinberg vSt sdk, which needs a registration on the Steinberg website), and linked against Qt4 gui library (QT5 version gave weird menus on a Unity desktop). HarmonySEQ is just as is, no special enabled or disabled features. Thanks to the authors of these cool softwares. Cheers, and happy composition. - Ben
