Synthfest Uk 2018

by Will Godfrey

I've posted about this various places, but seem to have forgotten here :( However, it's all good 'cos I keep remembering bits I'd forgotten about :) Some time ago I was again delighted to get an invite to set up a free stand for Yoshimi at Synthfest UK (now in it's 3rd year). This took place in Sheffield Saturday, 6th October. The event went very well. Better I think that last year. It was certainly bigger, and I think the visitors more clued up about what to expect. Our stand was well placed and also got more attention that last year. I'm sure the posters helped - you really couldn't miss them :) The posters were designed by one of Yoshimi's Little Band of Helpers, and a musician friend who was also attending the event has contacts with a digital printing company. They produced them at no cost - along with some flyers. As well as the main laptop on speakers, I had a netbook set up with a two octave mini-keyboard and a pair of phones. The people who tried it were really impressed with the performance on such a small setup. There was also some discussion about running Yoshimi on a Raspberry Pi - all housed in a small box with a minimal touch screen - Interesting idea. People are definitely less 'scared' of Linux these days, which is good, although again, there was some discussion about porting Yoshimi to the Mac. My attitude has always been that I'm fine with that and will help where I can, but know nothing about the architecture so wouldn't be able to do any of the work myself - especially as I'm still up to my eyeballs with work already :( I was surprised that nobody at all mooted the idea of a port to Windows. Another of YLBoH produced a pretty sophisticated backing track, playing on parts 18-28 while parts 1-16 were on Solo-TwoWay. It certainly got people's attention, as did the fact the whole lot was pulled in with just a Rosegarden file and a Yoshimi State file, so ideal for gigging. There were no blind people there this year, but one guy, who remembered the command line feature from last year, really liked the new extensions into the synth engines. The greatest, most pleasant surprise was the (fairly elderly) wife of a friend who was quite interested in the actual sound banks, and impressed with the reproduction quality. She is actually a folk musician and has always used real instruments, but seemed quite comfortable using the keyboard to play some of the piano-like sounds. Below are links to some photos I quickly took just as the event was about to open. I'll leave them on my website for a week or two. www.musically.me.uk/Photos/Synthfest2018/Synthfest2018_01.jpg www.musically.me.uk/Photos/Synthfest2018/Synthfest2018_02.jpg www.musically.me.uk/Photos/Synthfest2018/Synthfest2018_03.jpg www.musically.me.uk/Photos/Synthfest2018/Synthfest2018_04.jpg www.musically.me.uk/Photos/Synthfest2018/Synthfest2018_05.jpg www.musically.me.uk/Photos/Synthfest2018/Synthfest2018_06.jpg www.musically.me.uk/Photos/Synthfest2018/Synthfest2018_07.jpg www.musically.me.uk/Photos/Synthfest2018/Synthfest2018_08.jpg www.musically.me.uk/Photos/Synthfest2018/Synthfest2018_09.jpg -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.

GxPlugins.lv2, Wayland and X (Was: Re: Linux-audio-user Digest, Vol 140, Issue 9)

by Juha Siltala

Ecasound audio looping

by Joel Nash

Hi, I'm looking for ecasound experts, I’m using csound to write audio files that I then mix with ecasound. I want to know more about how ecaound reads the audio files. What I tried in ecasound was -audioloop so that the same file is read over (simple enough). I’ll then make adjustments to this file and whilst maintaining the same name on the same path for that file and then recompile csound to essentially make a new file. When ecsound “realises” this it has to stop? I then have to exit and reopen ecasound and play the file again. Is it possible to have ecasound just continue reading the file thats named in the command? what makes stop reading the file? ...perhaps before ecasound loops again it can reload the file into the buffer to I don't can to hit command interrupted and restart the engine each time I make an edit to the file thats looping? I hope this is clear enough of an idea here. Many many, thanks

It seems Canonical made things way more difficult than it should be. On Fedora there is a settings button where you select or enter your user name on the gdm login screen. There you can select Gnome (defaults to Wayland), Gnome on Xorg, KDE Plasma (defaults to Xorg), KDE Plasma on Wayland, and if you have other desktop environments those have menu entries as well. There should be no need to disable either xorg or wayland, the system should be able to start the correct environment when needed. My system goes back and forth, I typically use Plasma on Xorg, one of my kids used to use Gnome on Wayland, but some game didn't handle graphics correctly on Wayland so switched back to Gnome on Xorg. The screen goes blank for about a quarter or half second when switching back and forth between a Wayland desktop and an Xorg desktop, but that is the only noticeable effect. -- Chris Caudle

And it doesn't run reliably even then. In that case, maybe Ubuntu's Wayland or XWayland implementation is a bit "special". It is *supposed* to work just like that so that you don't even know, and it does work on most systems. JS

GxPlugins.lv2 v0.5 released

by Hermann Meyer

Hi Today I released a new version of the GxPlugins.lv2 package. GxPlugins been Lv2 plugins based on circuit simulations from various pedals. True mostly they are distortion pedals from the last century. :lol: Some of them been amp simulations, some been plain filters. However, this release introduce the switch from GTK based user interfaces to Xlib based ones. This means, they will work now flawless in nearly any host, at least in any I've tried so far. As well this release add a couple of more sims, from changelog: add GxHeathkit.lv2 add GxFz1b.lv2 add GxFz1s.lv2 add GxKnightFuzz.lv2 add GxLiquidDrive add GxDOD250.lv2 add GxMicroAmp add GxTubeDistortion As a side note, GxPlugins been developed with the MOD as host in mind, therefore they are optimized to use as less CPU power as possible, therefore they work best at the SampleRate the MOD use, which is 48kHz. They work as well on 96kHz (by downsampling), but don't use them in projects with 44,1kHz or 88,2kHz. So, here you go: https://github.com/brummer10/GxPlugins.lv2/releases regards hermann
