Hey everyone! When I am playing a MIDI file with Timidity, I would get warning messages along the lines of: *No instrument mapped to tone bank 0, programm 11 - this instrument will not be heard.* Is there a way to somehow automatically map something to this missing instrument? If not with Timidity, then with some other MIDI player? Louigi Verona https://louigiverona.com/

Sonoj

by Will Godfrey

Just wondering who else will be visiting Sonoj this year. I finally managed to get travel and accommodation sorted out this year, so I'll be there as a visitor. Hmmm... Hope that doesn't put anyone off :P -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.

SynthfestUK 2019

by Will Godfrey

Oops, almost forgot this :o I'm now quite well known by the Synthfest organisers and even had a pre-printed badge this year :) I had a hour to set up, but actually managed to get everything up and running within half an hour, including a Raspberry Pi 3B. Once set up, I had time for a quick look around the other stands. The balance was more towards hardware rather than software this year, and I didn't see *any* windows boxes at all. There was lots of modular stuff, kit form as well as pre-built. The big boys, Yamaha, Korg, etc. had their own individual rooms on the lower floor, and the talks were held in a nearby annex. Unfortunately I wasn't able to get away to see any of those - I think I need an assistant on the stand! When the doors were opened, it became very busy indeed. Something like twice as many visitors as last year, and more seriously interested rather than just curious. I was kept pretty occupied the whole day. I had the pleasure of two very good musicians playing on the laptop driven larger keyboard, one of which decided the 64ft Organ sound was ideal for a quick rendition of Bach Toccata & Fugue in Dm! The Raspberry Pi, got a lot of interest, and outright astonishment from quite a few people. There is a very good chance we'll get more users via this route. The idea of this as a stand-alone synth 'module' seemed to catch on straight away. I had plenty of the flyers from last year and a good number of them were picked up. I also had 40 laminated 'mini' banners with contact info on the reverse side - I only brought three of these home! The guy who got the big banner printed for us brought it with him, but his train was delayed, and he was only able to get it to me mid morning. He'd been told they'd actually printed two copies, but didn't realise they were both on one sheet, and we didn't have the means to cut it in half. We quickly put it up, but it's not quite how I intended - nevertheless it looks very good. I love the way the person who produced the artwork came up with the expressions on all the little robots :) Photo here - quite good detail if you zoom in :) www.musically.me.uk/Photos/Synthfest2019/Synthfest2019_12.jpg -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.

what is a good linux distro that supports Ardour?

by jim

My current system is pretty old. It's running on a five-year old desktop Zareason computer. I'll replace the hard drive and want to install a new distro. What's your recommendation? with thanks, jim

lv2core any alternative ?

by Banibrata Dutta

Hi, Having installed Lubuntu 18.04.3 64-bit on my old Laptop, I realized that the calf-plugins from the distro's repositories were perhaps quite old (0.60) while the latest available from calfpluginstudio are 0.90. I am thinking of building from source (unless someone has a good PPA), but building from source requires the package 'lv2core' to be installed, where-as it seems that Ubuntu 18.04.3 no longer has this package (which is supposed to be a 'dummy' package). Any thoughts on whether there is an alternative dummy package, or if I could ignore it and proceed with the build ? thanks, BD <http://twitter.com/edgeliving>

[Music]: Cooking Meth (an experiment)

by Jeanette C.

Hey hey, whilst on holiday I did not only play the piano and embarrassingly sweet ways. My friend has a very lovely studio with a powerful Linux machine and some outboard equipment. So as an experiment, we did record a very short electronic piece. For now, I'd like to show withgout further comments about the experimental nature, maybe it is obvious after all: http://juliencoder.de/nama/cooking_meth.ogg http://juliencoder.de/nama/cooking_meth.mp3 Feedback is welcome, especially if something strikes you as particularly odd about it. :) Or if you just happen to like to really hate it. :) Best wishes, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * SoundCloud: https://soundcloud.com/jeanette_c * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * GitHub: https://github.com/jeanette-c * Twitter: https://twitter.com/jeanette_c_s I can't believe it's what I see That the girl in the mirror The girl in the mirror Is me <3 (Britney Spears)

Xrun solved thanks to liquorix kernel

by Banibrata Dutta

Hi, Had been struggling with getting rid of Xruns based on various recommendations like switching to low-latency kernel, turning off WiFi, changing audio interface to other USB ports etc. This is a i5-8400 + 16GB DDR4 + SSD based system running Lubuntu, and with 128*2 buffer-settings. Xruns were seen with almost no non Jack applications running, barring say htop. However tried the Liquorix kernel based on someone's advise on a similar topic, and it seems to have completely solved the issue of Xruns. Now I have perfectly glitchfree recordings, several other applications (some quite heavy) running. Thought, I'd share with the community here. Cheers, BD

calf-plugins: why only few have 'byepass' button ?

by Banibrata Dutta

Hi, Had a great time playing around with calf-plugins and doing some live vocals (except the few rare xruns that still do trouble me). However, I noticed that while 'Reverb', 'Chorus did not have a byepass button, few other ones did. What gives ? Also when a signal is bypassed, does the overall signal-chain latency drop (because DSP overheads drop) ? -- regards, Banibrata Dutta

[ANN] The QStuff* Autumn'19 Release

by Rui Nuno Capela

Hello there! It's coming true: the old bunch of Qstuff*, QjackCtl [1], Qsynth [2], Qsampler [3], QXGEdit [4], QmidiCtl [5] and QmidiNet [6], are all catching up and aligning to the magical version 0.6.0 :) That's all pretty much and enough for now ;)... ** QjackCtl - JACK Audio Connection Kit Qt GUI Interface [1] ** QjackCtl 0.6.0 (autumn'19) is out! QjackCtl is a(n ageing yet modern, not so 'simple' anymore) Qt [7] application to control the JACK [8] sound server, for the Linux Audio [12] infrastructure. Website: https://qjackctl.sourceforge.io http://qjackctl.sourceforge.net Project page: https://sourceforge.net/projects/qjackctl Downloads: https://sourceforge.net/projects/qjackctl/files - source tarball: https://download.sf.net/qjackctl/qjackctl-0.6.0.tar.gz - source package: https://download.sf.net/qjackctl/qjackctl-0.6.0-39.rncbc.suse.src.rpm - binary package: https://download.sf.net/qjackctl/qjackctl-0.6.0-39.rncbc.suse.x86_64.rpm - AppImage [20] package: https://download.sf.net/qjackctl/qjackctl-0.6.0-39.x86_64.AppImage Git repos: https://git.code.sf.net/p/qjackctl/code https://github.com/rncbc/qjackctl.git https://gitlab.com/rncbc/qjackctl.git https://bitbucket.com/rncbc/qjackctl.git Change-log: - Graph: avoid self-connecting over their own ports when client nodes are selected as a whole group; also try to match port-types in a orderly fashion when connecting multiple selected ports. - Changing current JACK buffer size from Setup dialog (cf. Settings / Frames/Period) may now take effect just immediately ;) - An 'Apply' button as been added to the Setup dialog; ask whether to restart the JACK audio server, if any settings are changed. - Added alternate yet non-official CMake build option. - Fix HiDPI display screen effective support (Qt >= 5.6). - Command line arguments (--start, --preset=[label] and --active-patchbay=[path]) are passed and take effect on the current singleton/unique application instance, when enabled and already running. - System-tray icon context menu has been refactored to be exactly the same as the main-window context menu that is re-instantiated on demand. - Make sure compiler flags comply to c++11 as standard. ** Qsynth - A fluidsynth Qt GUI Interface [2] ** Qsynth 0.6.0 (autumn'19) is out!

QmidiCtl [5] is a MIDI remote controller application that sends MIDI data over the network, using UDP/IP multicast. Inspired by multimidicast [15] and designed to be compatible with ipMIDI [15] for Windows. QmidiCtl [5] was long ago designed for the Maemo [17] enabled handheld devices, namely the late Nokia N900 [18] and promoted to the Maemo Package [18] repositories. Nevertheless, QmidiCtl [5] may still be found effective as a regular desktop application and recently as an Android application as well.
