Re: [LAU] Open Sound Interface project beginnings

by Christoph Kuhr

Hi! great idea!!!!!!!! im desperatly looking for AVB (IEEE 802.1BA) adc/dac s. this could be THE solution... > 1. Modules for dac and adc with on-board identifiers (mixed-signal design) > 2. A FPGA-based programmable system board with connectors for > respective modules (high-frequency circuit design) > 3. FPGA code for buffers, clocks, and device discovery (VHDL/Verilog > programming) Did you have a look at opencores.org for IPs? I2C and I2S cores are available at opencores.org > 4. Data transport modules (FPGA code plus hardware design), could be > USB, FW, ETH, PCI, wireless, etc... Perhapes two transport modules? like FW and ETH -> AudioVideoBridging? (they share the same codec implementation: iec61883-x) if you like to use it with a laptop, use FW. if you have a little projectstudio with seperated recording/control room situation it would integrate in an AVB environment. The DAW would need to have an AVB ready NIC, means PTP HW timestamping between PHY and MAC. At the moment im working on a linux implementaion for AVB, perhaps this is what i could contribute? my implementation will be jack a application... There is an AVB properitarien IP for FPGA, apparently 25000€. => there would be the need for opensource implementation. so i would like to contribute my AVB stuff if/when i got it working -> estimated deadline july 2012... after that i would like to have a look at an open AVB IP for FPGA. bye Ck

New music, made with Ardour 3

by Leigh Dyer

Hi all, I've just finished my first track that makes extensive use of Ardour 3's MIDI features. I definitely put it through its paces -- there's MIDI CC automation, plugin and fader automation, and synths of all varieties (hardware, external JACK software, and LV2 and VST plugins): http://wootangent.net/~lsd/music/releases/texel/texel.ogg http://wootangent.net/~lsd/music/releases/texel/texel.mp3 http://wootangent.net/~lsd/music/releases/texel/texel.flac I ran in to my fair share of problems, as you'd expect with alpha software, but overall I think Ardour 3 is shaping up very well indeed. I've written a bunch of details about the production on my blog; links are provided below: http://wootangent.net/2011/10/new-track-texel/ http://wootangent.net/2011/10/new-music-update/ Hope you enjoy it! Thanks Leigh

No sound from Qsynth 0.3.5 and 0.3.6 when using Jack MIDI on Jack 0.3.6

by Artem Vakhitov

Hi all, when attempting to try out MIDI capabilities in the latest Ardour 3 alpha build, I seem to be unable to get audio output from Qsynth when using Jack MIDI engine. Qsynth is being triggered from A3 (as indicated by its tray icon), the MIDI channel is right, the Qsynth audio output is connected in QJackCtl, and yet there is no sound. With alsa_seq MIDI driver, Qsynth does output audio, but A3 doesn't support that. This is on Squeeze, A3 alpha 10, jack 0.3.6, Qsynth 0.3.5 and 0.3.6. Any clues what's going on here? Regards, Artem Vakhitov

metronome survey

by Raffaele Morelli

Hi, I've tried: - gtick but it's not "jack compliant" - kmetronome but didn't get it works with fluid soundfonts - klick works fine for me, but not for my woman which is a dummy linux user :-) so, which metronome gui-app do you use... if any? regards -r -- *L'unica speranza di catarsi, ammesso che ne esista una, resta affidata all'istinto di ribellione, alla rivolta non isterilita in progetti, alla protesta violenta e viscerale.*

Recommend inexpensive monitors and headphones

by Artem Vakhitov

Hi all, can you recommend me some inexpensive but good small monitors and headphones for home recording? No high aspirations yet, just for doing various demos on my laptop. Admittedly, I don't know how to define "good" here, I just need them to be perceptibly better than your average desktop speakers and earbuds :) Similarly, I don't really know what "inexpensive" is referring to the above, but as a wild guess, let's start from $100. I prefer plain audio solutions, though will consider USB ones (my Samsung Q70 has two US ports only, so that puts some limitations). Regards, Artem Vakhitov

Multitrack recording with MIDI sync?

by Mario Lang

Hi. This question might sound stupid to some, however, I have never done something like this before in Linux and would love to hear your tipps: I am trying to record a multitrack thing with my x0xb0x. In other words, I'd like to record *two* tracks generated by the external synth sequencer, but in sync to each other. Since I have never played with transport things, I am looking for hints on how to do it. Since I am limited to command-line tools, I would like to do it with ecasound, backed by JACK. Right now, my x0xb0x emits MIDI clock sent to a DR202 drum machine. Can I somehow record the MIDI clock along with the first track, and resend it in the second recording so that everything is in sync? Or, should the PC emit MIDI clock (how?) so that everything starts in time? Any hints are very welcome. -- CYa, ⡍⠁⠗⠊⠕
