Hello all, I'm considering to test Linux mint for my 'sound machine' - a normal laptop that's used for modest recording and editing of sounds and music, as well as miscellaneous office work. Anyone here try that before? Any pitfalls to avoid? Regards, Alf

Re: [LAU] Linux mint for audio?

by Edward Diehl

I'm using Mint 19.1 on a recent Dell 15" XPS laptop and my experience is excellent for general use and good for pro audio. I find to be Mint to be quite polished and supports this laptop very well. What I particularly found impressive was: I was able to install with Windows10 dual-boot effortlessly, no problem with UEFI, secure boot, or GPT partition; Out of the box support for using both Intel and Nvidia graphics card (nice applet to switch between them) Bluetooth works effortlessly (mouse, headset). Laptop has touch-screen, which seems to be basically supported (can move windows around, though I don't really use this feature). All laptop buttons work (to control audio, screen, etc) As far as audio goes I added kxstudio repositories so I have the full audio suite. There is a low-latency kernel available, so I use that. I have turned off hyperthreading which I believe helped x-runs. There is a mint backup tool which I disabled immediately because it gobbled a huge amount of CPU and disk space. I have run some checks with realtimeconfigquickscan script, though I did not do all recommendations, maybe I should complete that. Of course, when doing audio I switch to performance mode on CPUs. I have run Jack with both onboard audio and with a Komplete Audio 6 USB interface. Both worked with no problems. Currently the setup is quite adequate for mixing at high-latency, very few x-runs. Low-latency work still gets some x-runs, sometimes in bursts. Clearly there process waking up or something which causes x-runs. Possibly things like networking. Need to spend more time figuring this out. What is impressive is that I am able to run Pianoteq at 48kHz, 64 frame/periods, 2 periods, 2.67ms using the USB midi connection on my keyboard and the on-board audio with no x-runs. I also play soft-synths using Ardour as a host, but this does not work well so far, many x-runs. So I'm hoping with a little more tweaking to get rid of the x-runs entirely. Also I left a free partition so I may try some other distro. AVLinux would have been my first choice, but unfortunately it does not support GPT partitioning, so is essentially un-installable (unless I revert to MBR) Edward Diehl

dkbuilder: from circuit to LV2 plugin

Well, I'm a Troll, keep that in mind before you go on reading, special, because all I want to give you here is a link, trollish, isn't it. https://linuxmusicians.com/viewtopic.php?f=44&p=102574#p102574 If you still read, okay, I'll give you a bit more than just a link. It's about converting a circuit drawing to a LV2 plugin, a working solution. regards hermann

List on emergency moderation

by David Runge

Folks! This list is on emergency moderation until further notice. Apart from that, I have removed Ralf Mardorf from the lists, as he repeatedly did not care about escalating arbitrary topics (after several times of telling him to stop) - aka. "trolling", insulting people and spamming. I hope this gives everyone some cool-off time. Please try to remember, that there are over 700 people subscribed to this list. Please don't enforce your personal issues onto others. Be mindful and respectful in what you write. Do not take part in distro wars (aka. "flaming"). Think before you write. Last, but not least: Be constructive! If you can't adhere to this (simple) social standard, this (and most likely most other) mailing list is not for you. Best, David -- https://sleepmap.de

Maudio M-track eight

by Will Godfrey

I bought one of these last August, and it failed catastrophically within a week, got a no-quibble replacement and tested all functions and it was fine. I used it a couple of times for recording guitar and mic into the computer, but since then only used it for playback from the computer. Try to use it for recording again, it's silent. Direct out is fine, and playback from the computer is. qjackctl shows the inputs, and appears to connect them correctly, but no data is coming through. The only change in that time was the distro on the computer being changed from debian to devuan. However, I also tried it on my laptop (which is still on debian) and got the same results there. Has anyone else seen a similar problem, or got any suggestions as to what may be wrong. -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.

Sonoj 2019

by Will Godfrey

Is there any likelihood of this happening? Last year it was in October and so close to SynthFestUK that I couldn't get the time off work to do both - this year that won't be a problem - so long as they are not in the same week! -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.

Plagiat experimental-oriental-rap (former Sebkha) first clip Snapchat au Harem - made with free softwares only

by ORL - AMMD

Hi all, As some of you know, I've been playing in Sebkha-Chott for fifteen years, an experimental and avantgarde rock/metal band from France, in which we used free softwares only for recording as well as on stage. We developped some softs as well. Sebkha-Chott has ended in 2015, and by that time, we were a trio, augmented by machines (synths, samplers, loopers - many of them - FX, routing, mix, and so on). Plagiat started at the end of Sebkha-Chott, and was thought around the same setup, though it is a drum/bass/vocals duo, and is more orientated in oriental-experimental-rap. We just released our first clip, all built with free softwares only (in the AMMD studio www.ammd.net), you can check it here: https://plagiat.org/snapchat-au-harem and you can check more on http://plagiat.org (by now, it's mainly in french, but we could translate it if someone demanded it!) As you might want to know a bit more, here is what we've been using and/or are using by now: *For this clip:* *- hw: Alesis HD24XR -ADAT- RME HDSP9652 / TL-Audio Ivory II series Preamps / Focusrite Octopre Preamps * - debian testing - ardour5 (mix and mastering) - zynaddsubfx - x42-fat homemade patch - calf, caps, swh, tap, invada plugins, and maybe some others we forgot - calfjackhost (just because calf 30 band eq didn't work well straight in ardour5) - kdenlive - gimp - inkscape (and maybe some others we forgot) * * *On stage (https://github.com/PlagiatBros/PlagiatSetup)* *- hw: 2x Focusrite Saffire Pro40 -ADAT- RME HDSP 9652 * - debian testing - gladish (yes, it's still working, but we know we will have to change this soon) - zynaddsubfx (with microtonal settings) - non-mixer (many instances) - seq24 (with a homemade-patch) - tapeutape (same as gladish) - x42-fat (12 of them) homemade match to get one octave up and down offset, and microtonal settings - guitarix (actually only for tuning, was used for more before, but ain't no guitar left, so...) - fluidsynth and one rhodes sound font - sooperlooper (8 stereo loopers) - mididings (many many many instances and patches and homemade forks for managing OSC) - calf, caps, tap, swh, invada plugins - OSC - pytaVSL (https://github.com/PlagiatBros/pytaVSL) : homemade light VJ soft - QLC+ - OpenStageControl (developped by Plagiat's drummer) (and maybe some others we forgot) *For upcoming clips (work in progress by now):* - synfigstudio - qstopmotion - lives Well, that's it for now.

how to match tempos

by wferi＠niif.hu

Hi, Suppose I've got recordings of two live performances of some piece. I'd like to mix them but their tempo is slightly different and each one also varies naturally. What is a good workflow for time-stretching one of the recordings to match the tempo of the other? For example I could create a series of tempo ramps in Ardour to align the metronome clicks, but how do I proceed from there? Slicing up the other recording at each bar and time-stretching the slices manually to match the tempo bars sort of works, but it's rather cumbersome and misses the "ramp" part. I'd rather create both "tempo maps" and have some tool do the appropriate ramped time-stretching for the full piece in one step. Does anything like that exist? Or can you recommend a more practical approach? -- Thanks, Feri
