Native Instruments Traktor just appeared on Freshmeat! :) I guess some people are starting to take notice of the OSS community. Though it isn't OSS in itself and not available for Linux (OS X, + a few marginal os:es). But the most interesting thing was that they used Freshmeat as a marketing channel. There goes the neighborhood... I'm not sure if I like it, that freshmeat now includes non-free commercial software only available on non-free commercial OSes ciao -- Allan Klinbail [EMAIL PROTECTED]
Re: [linux-audio-dev] libakai
Hey There Does this mean I can read and listen to my MPC200xl .snd files? What about editing, which software can read it? cheers Allan On Thu, 2003-06-12 at 22:28, Christian Schoenebeck wrote: Hi!

Re: [linux-audio-dev] Re: [linux-audio-user] Re: New LADSPA Hints -clarification of definitions
Hi All Can I clarify a few definitions here based on real hardware usage. I think there was one more too, but I can't think what it was... I remember one about sidechains or something. I don't know what a sidechain is, though, I just recall seeing it somewhere :) I dont think that one is practical. A sidechain is a send/return insert for a single device.. e.g. if you don't have mutiband compressors (but had three standard compressors) but wanted to compress specific frequencies you would plug an eq rack into your sidecahin in/out plug of your compressor..then the signal output of the compressor is what would be compressed. Say by boosting the bass frequencies, the bass frequencies would be compressed more than the rest of the signal. .. A simpler example would be wanting to distort a signal before compressing it. The distortion unit would be plugged into the sidechain. I suggest going to a hardware manufacturers site, say DBX and downloading a pdf of a compressor manual and investigating the block diagram. The reason for using a sidechain (in the hardware world) as opposed to plugging everything inline.. is simplification of patching and minimising the number of cables being used. In software there would be no reason other than aestethics to include a sidechain as it is possible to plug modules into each other in series without getting ground noise from excessive amounts of cabling. So Steve you are correct it isn't really useful. For example the distinction between the control output of an envelope follower and the gain reduction output of a compressor, the follower is inteded to drive eg. a filters cutoff, wheres the gain reduction is just inteded to be viewed by the user as a clue as to what is going on. Correct about control output. However gain reduction on a compressor actually controls the output level or gain from the unit, it is not simply for the user as a clue as to what is going on.. Often when compressing the resultant output may be larger than desired... When compressing a signal, input level is often boosted to get more of an effect from the compressor (usually this is controlled with the input gain on the desk) which is why the output level would often be very high.. gain reduction is a way of counteracting this. Here is a simplified diagram of a system using desk inserts for inline compression within one channel of an analogue mixing desk. 0 ---0--0 --- 0 --0 BUS input input compressor eq level fader gain via section insert So using an insert means the input gain effects the input to the compressor and not directly to the desk channel. Without gain reduction the compressor is likely to send a signal that is is either hot (too high and hence distorting within the channel) or in some cases too low, making it impossible to give it effective signal level within the entire mix. This would be useful in a software compressor as well. As basic audio engineering tells us, the signal must be high enough to be clear of the ground noise and low enough not to distort within the mix. I hope this helps.. cheers Allan
Re: [linux-audio-dev] MIDI Clock and ALSA seq
Not being a coder so you can all shout me down in flames if you like if my response is misguided .. Thanks, but I really wanted someting with dynamic timing. Does this queue tie me to a particular BPM? All I wanted was to be able to put the tick out every 24th of the buffer. Isn't the pulse of MIDI clock defined by the BPM, that's how all instruments synced to MIDI clock work... I'm a little confused as to how they would otherwise as BPM is the defining feature of MIDI clock SMPTE/MTC is another thing though, it is timed in frames and maybe that is what you need here??? You should be able to alter the tempo in real time and MIDI clock send those changes through the system so that all machines can see that change i.e. my delay unit with MIDI controlled delay times only looks at the BPM, nothing else. Also think of 2 drum machines synced together... when one slows down the other must do exactly the same. I hope this is useful... but it probably isn't cheers Allan - Steve

I'm a little confused as to how they would otherwise as BPM is the defining feature of MIDI clock Not AFAIK. MIDI clock is just synced to bars and the receiving unit has to lock onto the pulses. I have a delay box that I wanted to sync to the software, its expecting 24 MIDI clock pulses per bar and will sync to that. I dont know if midi clock explictly states the BPM, but I know this particular box will track variably timed clock pulses in any case. As it happens I just fudged it by programming the tempo manually and sticking to one tempo. It worked ok :) but it isn't really what I wanted. You should be able to alter the tempo in real time and MIDI clock send those changes through the system so that all machines can see that change i.e. my delay unit with MIDI controlled delay times only looks at the BPM, nothing else. Also think of 2 drum machines synced together... when one slows down the other must do exactly the same. Yes, but I wanted to be able to track dynamic tempos, and I dont what to have to build a new queue for every bar. Also I wanted the beggining of the bar to line up with the beggining of the sample loop, which requires the pulse timing to be controlled by the player. It could be that I just misunderstood the code Takashi sent out though. - Steve
[linux-audio-dev] why is no-one responding are you all just a bunch of *^%^%^wits???
Hi Guys This is quite a disturbing message.. nearly 2 weeks ago Paul Davis marked one of my messages as something seriously wrong going on .. when libraries were compiling as dynamic not static... since then I have responded with full outputs of what is happening. In response I sent full output of what was going on .. tried to sort it out by myself and sent further results.. Okay some of it was too big to get to the list immediately pending list moderator acceptance.. and then some of it just purely didn't get responded to. I have done everything I have asked of me from the list, including Paul's responses ..and also taken my own initiatives following lack of response and still have recieved no response. Sure I am not a coder just a potential professional user.. but that really shouldn't be an issue... Okay some individuals responded to some of my initial questions, and thankyou to the two of them.. however noone has responded to further enquiries, after acting on the responses I did get.. Is it because I feigned mild support to Steinberg having (while unreleased) versions of their software for Linux?? Or is it because I'm obviously not a coder?? Is it simply because I used the wrong subject line? This disgusts me as about 2 years ago when I said I was going to give up on Linux to the LAD lists a massive response came about saying I should keep going and my opinions (not even problems relating to software directly) were valued and necessary. Now when I have real problems compiling something, contained with as much information I could forward were included it seems it is irrelevant and no-one seems willing to respond at all (let alone Paul) .. Other compile and/or configure problems have been responded too earlier than mine (at all really as my last few posts have not received any reply) even though I acted upon all requests made of me. I am active in all lists that I am involved in with any replies that I may have a potential answer to and have been promoting this OS and in particular the potential of Ardour to many fellow professionals in the industry. I also have rad and learnt as much as I could to give qualitative feedback to any problems I incur. All I seek is the ability to use open source software in preference to rip-off commercial apps. Yes, I admit there is potential for both to exist on this platform and would use some commerical apps to aide in crossover but that is not the point of this (ardour-dev) list. It would seem only the MusE list responds to anything I send, and only a few particular individuals at that. Aside from being upset, it appears to me that you guys are all a bunch of hypocrites.. Asking for further information, and clarification but never actually responding, while I do everything that I can possibly thing\k of in aiding you answer my questions.. yet continue to be ignored... It does not seem to be a coincidence that all response ended after my response to the string ahem. So I've wasted 2+ years of my life and countless dollars continuing down this path. Yes this is an emotional response as it seems like my friends advised me I should have just bought a Mac ,, inferior latency aside.. at least the support groups there (even those non-funded as this list) genuinely help. My only problem is , where do I go from here?? This really saddens me as I thought this (Linux) was the future. It seems it is only a future for the GPL elite. extremely pissed off Allan Klinbail
Re: [linux-audio-dev] why is no-one responding are you all just abunch of *^%^%^ wits???]
-Forwarded Message- From: Son of Zev [EMAIL PROTECTED] To: [EMAIL PROTECTED] Cc: Alsa-dev Thanks Vincent. Your reply is appreciated. However I have been involved in the ardour lists for over 2 years. I have spent much time reading about potential problems and responded to all those that have had the courtesy to respond. I have also learnt and spent much time investigating problems that have nothing to do with the production of music.. simply to try and help developers iron out problems.. Credit goes to some who have especially Takashi Iwai, Robert Jonsson, Tommi Ilmonen and a few others. If you look back into archives a couple of years back alot of development into inclusion of MIDI sync was added to some softwares (especially MusE) to accomodate users like myself who depend on this sync to make software compatible with real studios. BUT. In the last few weeks I have spent much time into trying to configure and compile ardour (the potentially greatest audio recording software available to us) but all my responses after I sent an opinion to the string ahem concerning Steinberg having produced (but not released) versions of their commercial softwares under our much loved platform, have been completely ignored.. except this one.. My responses have not been ignorant nor lacking in information. As I mentioned I have spent much time learning about the Linux platform and contributing when I can ... My annoyance is when it was asked of me to provdie more information and I did .. no response came.. then when I tried to resolve it myself and no further response came that's when I could only put 2 2 together and see that a response I made to the string ahem could have been related cheers Allan On Thu, 2003-02-13 at 00:50, Vincent Touquet wrote: I'm not a real coder either (so one might argue I shouldn't be on linux-audio-dev, but I'm just interested in the discussions), so I think I understand the root cause of your grief. I think if (if) the Ardour developers are _expecting_ quality feedback from normal users (not just programmers) at this stage, they should provide tarballs of the stable CVS snapshots they want to be tested. But maybe they want to wait for 1.0 before letting endusers test it? In that case, maybe you tried to use it too early in its development ? I think they honestly appreciate your effort to participate, there should be no doubt about that, but maybe Ardour is still changing too rapidly for you to be able to track it. I think only the developers of Ardour can clear out this question. best regards, Vincent

Re: [linux-audio-dev] USB Souncards
Hi This is more of a general comment I'd try and steer away from USB audio... Reports in magazines like Sound on Sound and Audio Technology (an Australian publication) don't rate any USB audio devices highly .. due to the low bandwidth and shared nature of the USB protocol. i.e. the FOstex USB Midi/audio desk (sorry can't remember the model) can't handle full spec MIDI and all audio processes at one time... When using laptops it is highly recommended to use a firewire hard disk as your recording media as the latency of the hard drive on even the best laptops is unacceptable under any OS (especially when multitracking even just on output). From reading the alsa-user-ML archives I have seen various reports. Basically ALSA has not written support for USB audio specifically as yet, however some people have had some luck in getting these devices to work. I would recommend posting a question to the alsa-user mailing list [EMAIL PROTECTED] (you need to be a member) to see how easily it has been done, and with which devices.. if this is your only option. My strongest reccomendation would be either to wait till there is a firewire audio device, with it's information released so that someone can write a driver specific to it. (i.e. not the MOTU or other devices currently out there). With any luck maybe the mLan spec will be available to open source developers at some stage and an mLan (firewire) device would be the strongest suggestion, especially with future studio expansion in mind.

As they only have USB in common I thought that might be best although hints in the earlier usb audio thread have worried me. If I'm paying a premium price for poor performance then I might just wait until I'm in a position to get a nice desktop. So, in short, what are the issues with USB sound cards under Linux? In particular, does it effect latency and realtime reliability? Thanks, Brad
