This is the initial release of XPolyMonk.lv2, a polyphonic version of Xmonk.lv2. XPolyMonk comes with 12 voices, full midi support and a integrated virtual keyboard. It use libxputty to create the interface: https://github.com/brummer10/libxputty The dsp part is heavily based on the FAUST `SFFormantModelBP` from physmodels.lib XPolyMonk is licensed under the BSD Zero Clause License, so you could do with it what ever you like. You'll find it's development source code here: https://github.com/brummer10/XPolyMonk.lv2 and the release here: https://github.com/brummer10/XPolyMonk.lv2/releases Happy Xmas to all hermann

by Rui Nuno Capela

Greetings! The old core of QStuff*, QjackCtl [1], Qsynth [2], Qsampler [3], QXGEdit [4], QmidiCtl [5] and QmidiNet [6], are all here and now bumped to **version 0.6.1**, making it the first batch for the last (northern) winter solistice of the decade. So here they go... ** QjackCtl - JACK Audio Connection Kit Qt GUI Interface [1] ** QjackCtl 0.6.1 (winter'19) released! 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.

pugl examples

by Will Godfrey

Does anyone know of any simple example files for pugl. I've had a good look around and can't find any. I know there are some fully-formed programs out there, but don't want the confusion of trying to find the core material so that I can understand it. -- 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.

Re: [LAD] Jack audio questions to aid in my development of audiorack

by Ethan Funk

Since I originally wrote audiorack using Apple's CoreAudio, I made design decisions based on the functioning of that API. Many of those choices needed to be reconsidered as I adapted the design to the jack API. A very big structural difference between the APIs is how "rendering" sample buffers is accomplished. CoreAudio provides a separate callback to get or deliver a block of samples for EVERY audio interface your program attachs to. For my program using that API, my design is based on an audio interface being choosen as a "master." This is the low latency interface that my code's core mixer is driven by. Other interfaces, both ins and outs, get an extra buffer between them and the core mixer. For the call-back code of these "slave" interfaces, my code compared the time stamps between the core mixer buffer, and the slave buffer to make a "phase" adjustment using Apple's varispeed resampling audiounit plugin with a PID error loop controlling the resampling ratio. This keeps the buffers, on average, in sync, but with extra delay to handle kernel callback scheduling jitter. i.e. no guarantee what order the OS will schedule the call-backs, even if they are on the same sample clock. So with this scheme, I could use any number of interfaces I wanted, each with it's own slightly different clock rates and drift, with one interface selected as the low latency master. After years of tweaking the PID filter, I had it working very well, with no cost (other than processor overhead of the re-sampling) to the master interface. Jack on, the other hand, has a single callback from which samples are received from jack source ports, and new sample data is delivered to jack destination ports. A very nice and clean approach, driven with a single clock source. And appropriate for interconnecting audio streams between programs. I like it a lot. I have lost the ability to allow for my software to handle re-sampling on multiple clock domains. I was thinking that zita-a2j, etc, was my path to get the functionality back. If I didn't have it working so well on OSX, I wouldn't lament the loss with jack. But it's hard to give up on it! Thanks for the Ubuntu Studio Control links. Ethan...

Xmomk.lv2 initial release

by Hermann Meyer

I like to announce the initial release for Xmonk.lv2 version 0.1 Xmonk is a sound generator based on the Faust `SFFormantModelBP` from physmodels.lib by Mike Olsen. It's a monophonic formant/vocal synthesizer. The source is a sawtooth wave and the "filter" is a bank of resonant bandpass filters. Xmonk provide a interface to drive the filter/synthesizer via mouse movement. Additional Xmonk provide a midi in port to drive it with any midi controller. On top Xmonk provide a virtual keyboard to drive it with your PC keyboard/mouse combination. Surely you could use your DAW automation to drive it the way you want. Xmonk could play in two different modes, on is the usual note on/off, the other is sustain, means the last note play forever, while you play with the vowel filter settings. Xmonk could be used with a free scaled temperament, or as selected with Equal Tempered scales from 12 to 53. Here you get it: https://github.com/brummer10/Xmonk.lv2 So, have some fun with it, hemrann

Work on linuxaudio.org this weekend

by Jeremy Jongepier

Dear all, This weekend the linuxaudio.org VM's will have to be moved to a different cloud region which could lead to some downtime of services provided by linuxaudio.org (i.e. mail and web sites). We'll try to keep impact as low as possible and are aiming at a seamless migration. This migration is necessary because the cloud region linuxaudio.org now lives in is being phased out. We'll keep you posted about the progress. Best regards, Jeremy
