Hi all! First time poster, long time enthusiast. I'm using: - jack-audio-connection-kit-2.9999 (+alsa, +dbus) - pulseaudio-10.0 (+jack) - alsa-utils-1.1.2 - jalv-1.6.0-r1 (+gtk) - calf plugins 0.0.60-r1 (+lv2) - cadence 9999-r1 (+pulseaudio) I'm working at scripting from the command line and I have a pretty good working prototype but I've hit an issue. - Running a fourth instance of jalv (either jalv or jalv.gtk) will cause the other three to seg fault. - I don't think the issue is confined to jalv, I've replicated it by running the jack meters in cadence. I'm not sure exactly where to take my issue but my first guess is jack configuration? Dede --- Dede Lamb ddlala27(a)gmail.com

btrfs & audio work

by Wayne DePrince Jr.

ahoy all, ran into the possibility of using btrfs [1] due to some non-audio related issues. it has some nice features, especially regarding backup, snapshots and silent file corruption detection. however, it seems like it lags a bit in performance when compared to ext4. also its stability status seems to change depending on what one reads. so i was just wondering if anyone has any experience using btrfs doing audio work? thanks, w [1] https://en.wikipedia.org/wiki/Btrfs -- http://waynedpj.ingiro.xyz

Yoshimi plays Widor

by Will Godfrey

This morning I posted a new youtube video of Yoshimi playing Widor's Toccata from a MIDI file. This originally came from a public domain library, but I know the piece pretty well and there were several errors in it. I edited these to get it sounding as close as as I could to what I expected, then added the CCs to the front of the file for Yoshimi's bank switching, program changes, and volume/pan levels - I didn't get the pedal level quite right. It tips into the red on the end of the very last note :( On a hifi with a good low end response this will really rattle your windows :) The recording was made with Simple Screen recorder. That accounts for why gkrellm is reporting a far higher processor usage than QjackCtl's dsp figure would suggest. https://www.youtube.com/watch?v=dcImV6NPP-c -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.

Release v0.1: IConnectivity MIDI Configuration Utility

by holger＠dehnhardt.org

Dear linux audio users and developers, (crossposting as usual for releases) at the end of the last year I bought a new MIDI interface. I decided to buy a IConnectivity MIO10 as it comes closest to my old (MOTU MIDI Express XT) as it was reported to work flawless with linux. It did, regarding the MIDI-Part, but as usual, the configuration was not possible with linux. As WINE did not work for me as well, I decided to create my own utility. And here it is: https://github.com/dehnhardt/mioconfig Currently it does support only a small part of the configuration possibilities, the interface provides (Read the RELEASENOTES.md for further information) and is prealphabetasomewhat - but as I did not implement firmware updates - it should (and in my case did not) not break the device. The utility should work with most IConnectivity MIDI devices but I ownly could test ist with my device. There are *no* precompiled packages at the moment, you have to build them. (It is based on QT) But I really apprecciate every input (please use the github issues) - and if someone wwould like to enable compiling under Windows or Mac (which should work as I use QT an RTMidi) - you are very welcome! All the best Holger

[Music] Cloud burst / Sheirgong (solo piano)

by Jeanette C.

Hey hey, I've just uploaded a new piano piece. http://juliencoder.de/nama/cloud_burst.mp3 http://juliencoder.de/nama/cloud_burst.ogg It all began with a simple chord of stacked quints and continued by the means of "what could come next?". The opening section is now rather dark and dissonant, but it evolves into a dreamy little piece. I used Fons' Zita-verb LADSPA plugin and some compression and limiting, since that was suggested to me a couple of times now. I tried to keep it all very natural and still dynamic enough to capture the original spirit of the song. Enjoy and let me know, what you think, if anything. :) Best wishes, Jeanette -------- When you need someone, you just turn around and I will be there <3

'morse code' picked up by the speakers

by jonetsu

Recently the speakers (Yamaha HS5) are 'picking up' 'morse code' (for lack of better description). I don't think this goes into any recording (haven't checked yet). So, erratically, maybe a few times per hour, the speakers will put out a short 'morse code' type of beeps, whether there is music playing or not. It could be at total idling time. They never did that before. My question is, what is the source of these short beeps ? Even if they are not recorded they can be disturbing when improvising or in a quiet piece.

Recbuf feedback glitches

by Johannes Kroll

Continuing work on my toy JACK sequencer. Today's new feature: Recording Buffer Feedback - https://soundcloud.com/antonsachzwang/tm-2017-06-12t002822 https://soundcloud.com/antonsachzwang/tm-2017-06-11t195355 Recorded "live", no postprocessing, no plugins or external effects used. Second example uses a single drumloop sample only. Cheers, J. -- Von meiner programmgesteuerten DV-Anlage gesendet

Looking for best-possible quality algorithmic reverb plugin

by Jeanette C.

Hey hey, I know, losely termed and fit for religious disputes, but I'm looking for a nice algorithmic reverb plugin (LADSPA or LV2) that can hold its own on a solo instrument or solo voice. There are some very good IRs and reasonably good algorithmic reverbs, that I use in mixes. But IRs aren't that tweakable - certainly not on the fly. I know of some applications that can do that, but all those that I know have a graphical user interface and thus are out. -- The algorithmic reverbs I know and use, are good, but not good enough for a good solo performance. I'm interested in everything from ambience to rooms and halls. Thanks for any tips. Best wishes, Jeanette -------- When you need someone, you just turn around and I will be there <3
