I have tried using Linux, but gave up when I couldn't get ALSA or OSS to recognise my USB MIDI interface, (a Yamaha UX96). Under NetBSD it's recognised as soon as I plug it in. I did Google around expecting there to be lots of convenient MIDI libraries, but I couldn't find any. Is ALSA that good that no one uses anything else? It seems to be overkill for System Exclusive stuff to use a high level library though, especially as the details differ on virtually every MIDI device. Chris

[linux-audio-dev] Re: [linux-audio-user] mapping alsa devices to oss devices

by Allan Klinbail

Hi I can't answer your question.. but this email has answered one of mine, and I have successfully edited my asound.conf file to be able to do what you are doing.. recording in through discrete channels and outputting though discrete channels.. Maybe someone on the ardour list can answer us both by confirming that this will allow multichannel recording on ardour (a possible solve to the question I think you are asking) cheers Allan P.S I'm still working on a way of then combining my Delta66 with my intel8x0 (built-in to MOBO) so that I can use the stereo out of the intel8x0 for monitoring while using the outputs of the Delta66 for channel recording. (i.e. sending output into the mixing desk to use outboard processing gear or for external mixdown of tracks) cheers Allan On Mon, 2003-06-09 at 20:25, Akos Maroy wrote: > In my quest to record from the different channels of the Delta 1010LT > have come so far that I can address the different hardware inputs using > ALSA device names, while using an appropriate /etc/asound.conf file. > e.g. I can > > arecord -f cd -d 5 -D channel2 test.wav > > and this would record from hardware input channel #2.

[linux-audio-dev] Bristol Synth

by Anthony

Hi, I've been playing a lot with bristol synth and really love it. So much so that I've been trying to 'Jackify' it. Actually, I'm pretty much done, but can't figure out the internal audio format. Its interleaved floats I think, but not normalised to [-1,1]. If any of the developers are here could you help me out? I can hear noise, but I need to tune the maths. TIA. --ant

[linux-audio-dev] GPL and VST.

by Torgeir Strand Henriksen

Hello A friend and I have made a VST plugin as a college project, and would like to open source it, and possibly port it to other plugin APIs. We are considering the GNU GPL for our licence, which has lead to this question: Does VST count as a special exception of being "anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable," or should we follow the suggestion about [1]controlled interfaces in the GPL FAQ?
