Hello, There is a problem with Bitwig not being able to activate audio for a project. I have a ticket opened with Bitwig support and now they are asking what are the parameters used in jackd for the 1010LT audio interface, with a shadow of a suggestion that it's either jackd and/or the 1010LT that's at fault, which I would doubt. I have the impression there could be a certain amount of back and forth with Bitwig support which is much more anonymous these days than it was a year ago. Is there a possibility to run jackd in full debug mode so that every message exchanged with Bitwig can be logged ? Thanks.

[LAU] spectmorph-0.3.3

by Stefan Westerfeld

spectmorph-0.3.3 has been released. Overview of Changes in spectmorph-0.3.3: ---------------------------------------- * Added portamento: - VST: support MPE to perform per-voice pitch bend (can be used in Bitwig) - new portamento mono mode (all hosts) * Added vibrato. * Internal improvements: - better property abstraction for (non-linear) UI properties - updated polyphase interpolator (used for vibrato|portamento) - fixed a few problems when developing against spectmorph(ui) libs - don't link against Qt UI library when only QtCore is necessary * Compile fixes for g++-6.3 What is SpectMorph? ------------------- SpectMorph is a free software project which allows to analyze samples of musical instruments, and to combine them (morphing). It can be used to construct hybrid sounds, for instance a sound between a trumpet and a flute; or smooth transitions, for instance a sound that starts as a trumpet and then gradually changes to a flute. SpectMorph ships with many ready-to-use instruments which can be combined using morphing. SpectMorph is implemented in C++ and licensed under the GNU LGPL version 3 Integrating SpectMorph into your Work ------------------------------------- In order to make music that contains SpectMorph, you currently need to use Linux. There are four ways of integrating SpectMorph sounds into music you create: - LV2 Plugin, for any sequencer that supports it. - VST Plugin, especially for proprietary solutions that don't support LV2. - JACK Client. - BEAST Module, integrating into BEASTs modular environment. Note that at this point, we may still change the way sound synthesis works, so newer versions of SpectMorph may sound (slightly) different than the current version. Links: ------ Website: http://www.spectmorph.org Download: http://www.spectmorph.org/downloads/spectmorph-0.3.3.tar.bz2 There are many audio demos on the website, which demonstrate morphing between instruments. -- Stefan Westerfeld, Hamburg/Germany, http://space.twc.de/~stefan

[LAU] Render and animate OctaMed songs in batch processing

by Henning Thielemann

Decades ago I arranged more than 200 songs using MED/OctaMED/OctaMED Studio on various Amigas. In the meantime I converted them all to MMD1 and MMD2 format. I wanted to render them to audio files (e.g. WAV) for use on CDs or MP3 players. I could render the MMD1 files without problems using UADE, however UADE refuses to render MMD2 (with mixer mode). XMP seems to play some MMD2 modules, but not all of them (maybe has to do with mixer mode). Radium seems to accept only MMD2 and not MMD1, but when playing there is only silence (whereas demo songs make noise, so no Jack problem). Is there a player that processes all OctaMED module formats? Or at least all MMD2 files, because I can still fall back to UADE for MMD1? Preferably a command-line player/renderer, because there are so many modules. Next step: I want to create music videos from the playing modules for upload, say, to YouTube. I am certainly not patient enough to perform all songs in OctaMED in an Amiga emulator (FS-UAE) and record the performances using a screen grabber (like ffmpeg -f x11grab). If playing in Radium would work, I could check whether it is possible to control Radium and screen grabbing from a shell script. However, I think I prefer a command-line tool that renders a simple animation of the rolling blocks into a video file for any song. Does something like this already exist? If not, what would be the closest point to start programming something like this myself? Would it be reasonable to try to hook in some of the tracker module playing frameworks like UADE?

[LAU] Yoshimi and THe Avenger

by Will Godfrey

While I'm in 'demo' mode, here is one where the main feature is the fairly new 'Solo' feature (since V 1.5.0) https://www.youtube.com/watch?v=ziuPJuDhjGw Although being replayed by Rosegarden the recording was made live in one pass with a simple foot switch changing active part. I'm afraid my timing wasn't up to much on this. I usually do much better. Other features used were a MIDI-learned main volume on a standard volume pedal (also since V1.5.0) and the bass line, although shown on the same channel is comming from an instrument on part 17. At the start, Yoshimi is set up in it's entirety with a single 'recent' state load. That includes all patches, Solo settings and MIDI-learn -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.

[LAU] jack application seg faults

by Dede Lamb

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

[LAU] 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

[LAU] 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.
