setting fluidsynth as a service in debian/systemd

by Federico Bruni

Hi you are my last resource. I'm trying to start fluidsynth in daemon mode (-s) at the startup. At first I tried to adapt a guide for Arch but I realized that in Debian (sid) the configuration is different: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=760210 I'm using systemd. I've tried several times to write a proper fluidsynth.service but I always failed. Here's my last try: --------------->----------------------------->----------------------------> [Unit] Description=FluidSynth Synthesizer After=syslog.target Before=sound.target Requires=dbus.socket [Service] Type = forking ExecStart=/usr/bin/fluidsynth -s -a alsa /usr/share/sounds/sf2/FluidR3_GM.sf2 Environment=DISPLAY=:0 #Restart=always #RestartSec=5 [Install] WantedBy=default.target #WantedBy=multi-user.target ----------------->-------------------------->-----------------------------> This is the error: # systemctl status -l fluidsynth.service ● fluidsynth.service - FluidSynth Synthesizer Loaded: loaded (/etc/systemd/system/fluidsynth.service; disabled) Active: inactive (dead) ott 02 19:56:00 fede-xps systemd[1]: Started FluidSynth Synthesizer. ott 02 20:13:51 fede-xps systemd[1]: Stopped FluidSynth Synthesizer. ott 02 22:09:05 fede-xps fluidsynth[24181]: fluidsynth: warning: Requested a period size of 64, got 940 instead ott 02 22:09:05 fede-xps fluidsynth[24181]: fluidsynth: warning: Requested 16 periods, got 8 instead ott 02 22:09:05 fede-xps fluidsynth[24181]: FluidSynth version 1.1.6 ott 02 22:09:05 fede-xps fluidsynth[24181]: Copyright (C) 2000-2012 Peter Hanappe and others. ott 02 22:09:05 fede-xps fluidsynth[24181]: Distributed under the LGPL license. ott 02 22:09:05 fede-xps fluidsynth[24181]: SoundFont(R) is a registered trademark of E-mu Systems, Inc. ott 02 22:09:05 fede-xps fluidsynth[24181]: Type 'help' for help topics. ott 02 22:09:05 fede-xps fluidsynth[24181]: > The error about the period size can be avoided setting "-z 940", but I don't understand why this error appears only when fluidsynth is started as a systemd service and not when I run that command in a terminal. I guess that it may be related to when the command is launched in systemd levels. I think that I should play with the values of After, Before and Requires in the Unit section. But I hope that someone in this list can help me, I don't have time currently to study systemd (and it would be probably too complex for me). Thank you in advance. Federico

Yoshimi 1.2.4

by Will Godfrey

Yes it's up there now :) The most noticeable change from a user point of view is that individual part outputs (corresponding to channel sends on a hardware mixer) are no longer affected by the main volume control. The panel window has also been updated to reflect this situation, and red 'clip' bars have been added. The accuracy of peak and clip indication has been improved and decay times increased to give a smoother, clearer response. There are the usual crop of small refinements and bugfixes under the hood. At the moment Sourceforge is still showing 1.2.3 as the latest version, although 1.2.4 is there at the top of the 'files' list. This happened once before and can't remember what the solution was. Has anyone else had this happen? http://sourceforge.net/projects/yoshimi/ -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.

New song: Never Stop Raising the Bar

by Gabriel Nordeborn

Hey all! After quite a long period of "no time or no space to make music", I've finally had time and peace of mind enough to sit down and make some new music. I've just published a new track to my SoundCloud, which features vocals from the user "snowflake" of ccmixter.org (a great resource for finding acapella/other remix material, which I sincerely recommend). It's a bit of hiphop/glitch mixed in there, and I hope you'll enjoy it. Please let me know what you think! :) https://soundcloud.com/zthmusic/never-stop-raising-the-bar If there's anyone who can't download from/listen on SoundCloud, just let me know and I'll arrange for an extra download through the website. The song is licensed CC-BY-SA-NC. Thanks a bunch for listening and for any feedback I get! Cheers, Gabriel/zth

Extracting a single cycle wave from an audio sample

by F. Silvain

Hey hey everyone, is there a tool to extract a single cycle wave from sampled audio automatically without control by sight? I want to extract such a wave from a voice sample. It won't be singing but talking. That way finding pitch and experimenting looks difficult for me. If at all possible, I'm looking for a non graphical utility. Thank you for suggestions!

I don't know if I have one that is so little compressed. The most I've picked up here & there was 96 and below, usually with an un- known history. Even 128kbit mp3 can be detected in a few seconds. Here I have done a/b testing against some well produced cd's I've ripped, and with ogg running at Q7, which gives a filesize similar to an mp3 at 128kb, and cannot tell the difference. Back these ears up 55 years to before I started wearing out rifle barrels, and I expect they might detect the diff. > By all means talk about low bit rate encodings and how they are no > good, but please folks - double blind testing doesn't lie, and the > double blind tests are close to unambiguous at this point.

How-to for simple recording for 3.5 hours?

by Jonathan E Brickman

Last Sunday I set up my laptop for a 3.5-hour recording session, Audacity crashed after 2.5 hours. Anyone know why this might have occurred, what to do about it, whether Audacity is in fact best for simple recording? Jonathan E.

Re: [LAU] qjackctl prettyname (metadata) patch (was: Bridging alsa and jack midi)

Re: [LAU] Bridging alsa and jack midi

Anyway, using the -X alsa_midi as > server option works. That is not true at all, Audio and MIDI are separate and so it is very possible (even likely) that the backend for audio may not be relevant to MIDI. MIDI is handled by ALSA, but is not treated as a part of the same audio interface as the sound that goes with it. So the user who has a FW audio IF with no MIDI would not be able to use a USB MIDI along with it if this was in the backend only. Along the same lines is the FW user who does have MIDI in their FW IF wants to use a lot of the older SW that creates ALSA MIDI ports they are again stuck if it is only available in the ALSA back end. The only thing I would like to see different in a2jmidi is the naming. (I am not sure how jack1 works) a2j opens as one client called a2j that when expanded has the alsa client name followed by the actual port name. This is hard to read and use. It is also confusing to new users who ask where the port is just because a2j has not been expanded. I would guess the best thing (from a user POV) would be for a2j to open a new jack client for each ALSA client with the ALSA name. I am not sure what other consequences this would have though :) -- Len Ovens www.ovenwerks.net

JACKDUB

by Patrick Shirkey

Hi, Some of you might be interested in a new project I have been working on: http://jackdub.channellinux.com/ It is a fully realtime automated music playback system built with various FLOSS tools. The system runs entirely in the cloud and doesn't even have a sound card. It's a work in progress so YMMV... Cheers -- Patrick Shirkey Boost Hardware Ltd
