Linux Audio Music has been dormant for a very long time, but recently I contacted the the person who hosted and ran it. The reason he closed it was because of a serious vulnerability was discovered in Rails, and he no longer had time to do the necessary upgrades. However, he has told me that he still has the entire database and the code. In his own words: "... would be happy to host and do what I can to facilitate a handoff to someone else who wants to manage it." For anyone who doesn't know, this was a relatively simple and clean site aimed specifically at providing a home for tracks composed with Linux - something rather rare! -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.

[LAU] jack-dssi-host: chooose plugin UI

by Jeanette C.

Hey hey, is there a way to choose a plugin's UI using jack-dssi-host from the terminal? I'm thinking of hexter, which has a gtk and a text UI, but I haven't been able to choose the text UI, since it's listed as the second one.

[LAU] OT: SSD disk prices have dropped?

by Ivan K

I need to replace a hard drive that recently went bad, and the new drive needs to be at least 1TB. I was looking on Amazon and debating whether to buy a 5400rpm versus 7200rpm disk, when, just for fun, I thought I would price 1TB SSD disks. I started finding things such as this: https://www.amazon.com/Inland-Professional-Internal-Solid-State/dp/B07FM9SS… Inland Professional 1TB SSD 3D NAND SATA III 6Gb/s 2.5" 7mm Internal Solid State Drive (1T) $140 (USD) https://www.amazon.com/Samsung-Inch-Internal-MZ-76E1T0B-AM/dp/B078DPCY3T/re… Samsung 860 EVO 1TB 2.5 Inch SATA III Internal SSD (MZ-76E1T0B/AM) $148 (USD) Can I just plug one of these drivex into a SATA plug on my motherboard and it will function just like a regular spinning hard disk drive? If 1TB SSD drives have become so cheap, I don't understand why anyone would buy a hard drive that spins anymore, but maybe I am missing something. Am I missing anything?

[LAU] samplerate conversion targetting number of samples

by Brent Busby

Anyone know some Linux CLI tools that would be good to batch convert a folder of 24/96 samples, mostly small waveform clips about two to four wavecycles long each, down to 8-bit...<drumroll>...and the nearest number of samples that's a multiple of 256 by stretching/squeezing, not by truncation (so as not to ruin looping)? You can see why I don't want to do this to a large number of files with a mouse in Audacity... :) Though if you did do it in Audicity, you can achieve what I'm trying to do by selecting the whole clip, selecting Effect -> Change Speed from pulldowns, plugging in a new length that's a multiple of 256 under New Length (with unit set to samples), and exporting the new file. Except, I really don't want to do that hundreds of times myself, so a scriptable CLI method would be better. Basically, I have some Multimoog waveforms that I've sampled with a good interface, but I'd like to bring them into an Ensoniq Mirage (8-bit), which likes everything to be on 256-sample page boundaries. I'm hoping to do some interesting hybrid/wavetable synthesis if I can get the waves into the machine. The target samplerate is unimportant, because the Mirage is going to adjust it up and down itself anyway because of the way its playback works. Only the length of the clips is important, which should be a multiple of 256 samples, and it can be downconverted by any amount that will achieve the length. Most samplerate conversion seems to target a desired frequency, but I'm targetting the number of samples, and I'm flexible on whatever frequency/resolution conversion is needed. -- - Brent Busby + =============================================== + "The introduction of a new kind of music must -- Studio -- + be shunned as imperiling the whole state, for -- Amadeus/ -- + styles of music are never disturbed without -- Keycorner -- + without affecting the most important political -- Recording -- + institutions." --Plato, "Republic" ----------------+ ===============================================

[LAU] MOTU Ultralite AVB - possible to configure two connected devices without 430 EUR switch?

by Hanns Holger Rutz

hi there, i found a number of related threads, seems mainly @Anders Hellquist who is using connected Ultralite AVB, but with the additional switch. i'm trying to determine whether this interface or the slightly cheaper mk4 (which has 2 more analog outs as far as i can see) makes sense for my setup. i have a performance project where connecting with another AVB device makes sense, so i'm tempted into the ultralite AVB. only... - manual seems to indicate that you can maximally route 8 channels either way, which is a bit silly given that I can already do that directly with the two laptops connected and Zita running... - also manual suggests that probably i won't be getting the web interface served just with USB connection, but only ethernet, so catch-22 if i want the two interfaces connected and not spend 430 EUR on a bloody specialised switch. isn't it possible to set up the interface when it's not connected to the second interface and then simply replug the ethernet cable? i guess the problem will be that i can tell it to send output channels to the other interface which is not yet visible? or other idea - simply use an off-the-shelf ethernet plug, then disconnect the laptop once the web interface is configured? ideas? better options for a 9.5" usb CC interface with at least 8i8o analog? i'm a happy user of scarlett 18i20, but it's often too big and heavy for travel. best, ..h.h..

[LAU] death by ogg vorbis

by Paul Davis

strange problem ... looking for clues. we have a slimdevices/logitech media server, and have had for more than a decade. we have 2 or 3 playout devices, one class and two "receivers". the system has worked solidly for a very long time. about a month ago, i download some awesome new London jazz from a project named Yuseef Kamal, as FLAC from Bandcamp. Sadly the project has since broken up, but "Black Focus" is phenomenal. As I usually do with FLAC or WAV downloads, I stash these files outside our music repository, convert to a lossy compressed format and then move the result into the music repository to keep the space down when we copy the whole thing to an SD card or whatever. The compressed format is generally always Ogg/Vorbis. So I did the same. Played the result on my main working computer (one version of the repo), and on my laptop (another rsync'ed copy of the repo). Entirely expectedly, it works normally. But then, after a lot of head scratching, I realized that whenever I try to play any of these files via the slimdevices/logitech server+devices, it does something to the server and/or the devices that requires a complete reset of the entire system. Switching to other music will not work - things are dead, even though they are superficially alive. I have never seen this behaviour from any other music/files. I can play the same files via some other media app on the computer where the server runs, and there are no problems. I've repeated this "experiment" at least 4 times so far. Playing a single track from the Yuseef Kamal album effectively crashes my logitech/squeezebox system (though the server is still responsive and the controller(s) still appear to do stuff. I've tried looking a debug logs fromthe server, but have seen nothing to indicate what is happening. I even reconverted from the original FLAC files, and tried those instead. No difference in the behavior. I have a few thoughts about things to try, but wanted to see if anyone else had any suggestions on approaches to the problem, things to look for, etc.

[LAU] Yoshimi Command Line Interface

by Will Godfrey

Our formal command line access is now almost complete. There are just a few remaining areas to be improved. The latest push has seen all the synth engine controls completed. We're not *quite* ready for a release, but would very much like people to try things out. We are actively looking for problems and inconsistencies between the CLI and GUI. Bank and root management have some naming and adjustment controls missing, and the effects parameters are not done - the effects themselves are, and so are effect presets. These were done quite a long time ago, and are being reviewed. The final missing piece in the jigsaw is copy/paste. This is an interesting one. I've a feeling that once the basic structure is organised, it will just slot into place like MIDI-learn, and reading limits/defaults did. There is likely to be some shuffling to get the most user-friendly command and parameter names. There is a huge amount of name duplication. Although this is convenient for developers and for the GUI, it makes it harder for CLI users to follow. We've already changed some of these to synonyms - and indeed also made some of the GUI names more relevant - but based on user feedback they may change again. There is now an extremely comprehensive and context sensitive help system in place. Typing '?' will give you the command information relative to your current context, but you can get any other context usually with just the first two or three letters, so while in the Part context '? sub' will show all the SubSynth commands, and '? li' will show all the dynamic settings that can be listed - such as what instruments are in the current bank. As usual the source code for the current 'master' is available from either: https://sourceforge.net/projects/yoshimi Or: https://github.com/Yoshimi/yoshimi -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.

Well, re-tread music actually :) Completely re-worked, and a percussion track added at the end. Oh, and it's all Yoshimi (bet that surprised you). http://www.musically.me.uk/music/Ghost_Train.ogg or http://www.musically.me.uk/music/Ghost_Train.mp3 -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.
