Hi, i've got a question, because I couldn't find anything in the documentation: Is it possible to run Ingen as Jack Client and if yes, how can I do that? I tried all the parameters and the GUI "ingenuity" (or similar) but either Ingen tries to connect to some unfamiliar servers or to start a jack-server itself (which doesn't work either). Beside this question, are there other modular DSSI-capable syntesizers besides Ingen (since AMS isn't DSSI-capable)? -- Best regards, Sebastian Tschöpel.

MIDI data dump utility

by lanas

Folks, What is the name again of that simple shell utility that simply displays all MIDI data ? I'm troubleshooting an Alesis Control Pad that, although always lights up Qsynth's green light, only manages to produce a sound from time to time any not on every hit, with just about the same velocity (i.e. the pad is hit with just about the same force. The velocity setting is flat. Cheers, Al

JACK/ALSA and openBSD/FreeBSD

by Julien Claassen

Hi everyone! Does anyone know if openBSD or freeBSD has support for JACK and ALSA? If so are there major constraints? Imprtant for me is: ALSA sequencer and JACK completely (audio/MIDI and jack_transport control).

splitting headphones output

by Atte André Jensen

Hi I have a technical question that's not directly related to linux, but my laptop (which is involved) is running debian and for this purpose csound... I'd like to have an ultra easy setup with my laptop/csound and three usb keyboards. Normally I drag three hardware keyboards, an external mixer and my two roland cube amps. The onboard soundcard in the laptop is good enough to be used in most situations, so I'm thinking: what would happen, hardware wise, if I split the mini-jack output of my laptop into two, one going to in-ears monitors, the other going to the PA? I expect the output level will be lower, but can it damage the laptop headphones amp, that's driving the mini-jack output? -- peace, love & harmony Atte http://atte.dk | http://myspace.com/attejensen http://anagrammer.dk | http://modlys.dk
