Secret (for a song)

by Philip Yassin

Hi list! Her is my new song: Secret <https://soundcloud.com/xaccrocheur/secret>. This morning the SoundCould announcement was retweeted by none other than Sir Stan RIDGWAY <https://twitter.com/philipyassin/status/762700853220405248>, and considering that I basically decided to become a musician while loop-listening to "Call of the West" back in 1982, there's an undeniable sense of accomplishment here, so don't kill my buzz ;) This is the 9th song in my "Faux Frogs" album <https://www.youtube.com/playlist?list=PLBvCHJWi9SXxIr3Zvv_9qygxuXv_F1pbb>, one more to go (she's been almost ready for months now) PS - if more and more people keep telling me that the lead voice is too low, I'm going to be forced to do something about it. The problem is that this very vocal take is a bit crappy (I just don't sing it really good) and if I crank it even a notch, this will show :| PPS - Everything goes into an IR modeled Lexicon 480L (using Klangfalter) and boy, I feel rich :) PPS - My new album is almost ready, greetings from the studio! -- Philip "xaccrocheur" Yassin http://manyrecords.com http://bitbucket.org/xaccrocheur / https://github.com/xaccrocheur

16.04, jackd and MobilePre

by worik

Friends I have recently upgraded my laptop to ubuntustudio 16.04 and I cannot get my MobilePre working. (It has USB ID 0763:200f) The setup is the same as on my other machine running 12.04 (vanilla ubuntu). On the 1604 I have tried it with and without running pulseaudio. Have other people had problems with 16.04? I have a sinking feeling I have a hardware problem Wori -- Why is the legal status of chardonnay different to that of cannabis? root(a)worik.org 021-1680650, (03) 4821804 Aotearoa (New Zealand) I voted for love

Focusrite Scarlett 8i6 recognised, inputs work, but no output - Mint 18

by Marco Donnarumma

Dear all, I have been using my Focusrite Scarlett 8i6 for a couple of years without issues on a Linux Mint 17 laptop. I can use the sound card only via Qjackctl (no ALSA out of the box). Now, I have a new computer (shuttle xpc slim) on which I installed Linux Mint 18. The sound card is recognised by both Jack and cat /proc/asound/cards. It even correctly appears in the system sound preferences, which did not happen in Mint 17. However, while the inputs work, there's no output. I've tested with a bunch of audio software, such as Pd, Ardour, Hydrogen, etc.. Interestingly, if, immediately after testing with Mint 18, I plug the sound card back to my Mint 17 laptop, at first, the sound card does not produce output. I have to power off the sound card and re-plug it, then it works. I would need this to work only with Jack, I'm not looking for an ALSA fix. I know in the past three years there has been a few ALSA patches to make this range of Focusrite work, and I think most of those patches are now in the mainline kernel. Although I'm not familiar with this. Does anything I could try come to mind? [SYSTEM INFO] Mint 18 kernel: 4.4.0-31-lowlatency alsa-base 1.0.25 libasound, etc.. 1.1.0 thanks in advance! best wishes, -- Marco Donnarumma, Ph.D *Performing bodies, sound and machines**Universität der Künste Berlin* http://marcodonnarumma.com 4w33534643646 --

[Music] jam25 feat. Wavedrum solo

by jonetsu＠teksavvy.com

Here is yet another improvisation, this time featuring a Wavedrum solo. Dusted off the Wavedrum, plugged it, and played a few 'notes'. The improv is built around a percussion loop to which a synth adds basic chordal colors. Guitars, vibraphone, bass drum, snare, strange metallic sounds, find their way. All was sketched and recorded in Bitwig then all individual tracks imported in Mixbus 32C to actually try to remove a few things, let the sounds breath a bit more by themsleves, trying not to compete for the same sonic spots. All work at that stage was done usign the imported audio - not additional playing. I mostly did this starting out as a mixing exercise. The outcome is pleasurable, and so I'd like to share. Enjoy. https://soundcloud.com/nominal6/jam25 Exported without normalization.

JACKD regularly grabbing a lot of CPU (90%+)

by Ffanci Silvain

Hey hey everyone, for a few months now my jackd1 (0.121.3) takes on a lot of CPU, even with no clients connected. Admittedly my CPU is down at 800MHz, one core most of the time. Normally JACK stays below 2% though. The kernel is: 3.9.0rc6 SMP PREEMPT (self built) For some reason I couldn't use JACKD2 - and at the time it wasn't advised anyway. Any idea, why this CPU-hunger might creep up? Things to look into? I'd be very grateful for hints.

Ardour 4, X32, and USB port

by Mac

Hi All, Using UBS 16.04, Ardour4, and the USB interface on the Behringer X32. Lashed up with JACK. The pc is a intel core i7, and I think I was using the usb3 port. Recording seems to work well, few if any xruns. But, playback is a different story. During playback, there are random clicks (or pops or clacks, how ever it might be described). They don't appear to be xruns. The same thing happens when using, say, Clementine to playback, so I'm guessing it's JACK, USB, or some other subsystem. Any ideas on what I might try to fix it? Regards, Mac

A bit of instrument patch investigation

by Will Godfrey

Recently I was given a Yoshimi patch set with one instrument that takes 11.5 seconds to load! It's a pure padsynth one with a very large sample size. Well the first bit of good news is that although it holds up the GUI for that time, everything else carries on serenely. However, this prompted me to implement a millisecond timer to find out just how long patches usually take to load. It has actually been very instructive! Almost all pure SubSynth patches take 1mS on my machine. AddSynth ones can be that low, but rapidly go up into the tens if you have things like unison and/or modulators operating. PadSynth ones start at around 40mS and are frequently up to 80mS. Then of course, there's that monster at 11.5 seconds! Some of my multi-engine patches are about 160mS. I don't know why we didn't think of this before. It will be very useful for getting the right position when you want in-program patch changes. In the current master I also added root and bank load times but in microseconds (MIDI & CLI only). Typically 15uS for a bank change, and 30uS for a root change, so it's probably not worth recording those! -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.

The Musical Artifacts Survey

by Lucas Zawacki

Hello all! Last year I launched Musical Artifacts [1] and have been maintaining it, steadily adding new features, new files, amassing a (modest) number of contributors and software integrations [2]. Anyway, I'm planning on dedicating more time to the website very soon and I've made a quick survey to help me focus my efforts based on what the users want. Here it is https://docs.google.com/forms/d/1VUGsBj1AUJgqiSZLelqERINbkfFJN4KTqG5KNfbIbr… It'll only take you a few minutes and will help me immensely. Thanks in advance! 1: Musical Artifacts is a web application aimed at helping musicians find, share and preserve the 'artifacts' that they use for producing their music. More info on the website (https://musical-artifacts.com) and wiki ( https://github.com/lfzawacki/musical-artifacts/wiki) 2: https://github.com/lfzawacki/musical-artifacts/wiki/Integrations

[OT] Searching for an 80s song

by Ffanci Silvain

Hey hey everyone, sorry for the OT< but I can't find it and it's driving me crazy. I'm looking for a song I remember from my early childhood in the 80s. I think the second half of the 80s and it starts with vocals only (or maybe a few drums). Someone sings "It's a love" in a high register and then the line is repeated about two octaves below. That goes on twice I believe. I have a feeling the drums were 80s drum machine or heavily gated with that typical roomey sounding reverb. But nothing else. That bit popped into my head a few days ago and even though I searched the net and a friends large music library, I couldn't find it. I have a feeling I might not even like the song particularly, but that feeling of being on the tip of my brain and not being able to grasp it, is driving me utterly crazy. Thanks for any help and appologies again for the OT> Ta-ta, ---- Ffanci * Homepage: https://freeshell.de/~silvain * Twitter: http://twitter.com/ffanci_silvain * GitHub: https://github.com/fsilvain
