Hi Gabriel, I am not sure from your email what is the level of your knowledge, so I will presume you know almost nothing (pardon me if I am wrong) Here's the way I use UbuntuStudio, and I guess everyone is using it in a different way 1. Jack (audio server) is at the heart of an audio system - it lets you route all audio and midi signals: - hardware audio inputs (guitar, mics) to software (Ardour,) - software outputs (Ardour, Muse) to hardware outputs (stereo out > amp > speakers) - software outputs (Ardour, Muse) to other software inputs (Effects etc) - midi inputs (keyboard midi out) to software inputs (Muse) - other midi signals routing: keyboard (Muse midi out to external synth or hardware stereo out or Ardour for audio recording of the midi signal) Please note that some programs let you edit the Jack connections via their own interface, some even insist on that (Ardour). ----------------------------- The second main use of Jack is that it serves as a Master Transport control - i.e. all 'jack-aware' apps start and stop the playback when one of them is started/stopped. Of course, you will need to check that jack-transport is enabled on most of them for this to work. Audio/Midi recording. There are all kinds of possibilities here. I personally use 2. Hydrogen - for drums. Comes with a few drums kits, lets you download more within the program itself. Excellent, intuitive drum-machine 3. Muse - for midi: it has a built-in soft synth, but I use it mainly for soundfonts (sf2). Soundfonts (or soundfont banks) are basically good and and not so good copies/emulations of real instruments (you might want to google here for MIDI standard, General Midi specifications, sf2 fonts etc) 4. Zynaddsubfx for generated synth sounds; it possesses many banks of ready sounds, and other users of this list have contributed with patches for its libraries. 5. Ardour for audio recording (mics, guitars etc), and fx (reverb, chorus etc) 6. Jamin - once I have all these 4 apps playing parts (drums, midi, audio) of my music, run them all through Jamin, trying to create a nice master track. The jamin output I usually record back in Ardour on a stereo track, and then right-click > export it on my computer. here's a good Ubuntu Studio link to get you into the things in a more technical/detailed way. <a href="https://help.ubuntu.com/community/UbuntuStudio">https://help.ubuntu.com/community/UbuntuStudio</a> I hope this helps.
