http://quitte.de/dsp/caps.html The latest release of the caps audio plugin suite contains a number of bug fixes and improvements as well as changes intended to make it more suitable for low-power systems. http://quitte.de/dsp/caps.html#CHANGES Most notably, support for a variety of little-used features has been dropped, reducing the binary size by roughly a third. There's also a new plugin implementing simplistic linear emulation of several guitar amplifier loudspeaker cabinets with reduced computational complexity: http://quitte.de/dsp/caps.html#CabinetIII The compressor plugins now report current gain reduction: http://quitte.de/dsp/caps.html#Compress http://quitte.de/dsp/caps_0.9.24.tar.bz2 Cheers, Tim

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

[ANN] Qtractor 0.8.3 - The Stickiest Tauon is out!

by Rui Nuno Capela

Howdy! Qtractor 0.8.3 (stickiest tauon) is out! Changes for this mostly just a bug-fix beta release: - Make sure any just recorded clip filename is not reused while over the same track and session. (CRITICAL) - LV2 Plug-in worker/schedule interface ring-buffer sizes have been increased to 4KB. - Fixed track-name auto-incremental numbering suffix when modifying any other track property. - WSOLA vs. (lib)Rubberband time-stretching options are now individualized on a per audio clip basis. - Long overdue, some brand new and fundamental icons revamp. - Fixed a tempo-map node add/update/remove rescaling with regard to clip-lengths and automation/curve undo/redo. - Fixed a potential Activate automation/curve index clash, or aliasing, for any plug-ins that change upstream their parameter count or index order, on sessions saved with the old plug-in versions and vice-versa. Description: Qtractor [1] is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework [2]. Target platform is Linux, where the Jack Audio Connection Kit (JACK [3]) for audio and the Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.

Linux Support for Focusrite Scarlett 18i20 2nd Generation

by Lloyd Dickman

I am trying to make a Focusrite Scarlett 18i20 (2nd Generation) work as a USB audio capture device with Linux. Using the most current Linux kernel without change (v4.12-rc6), Mic inputs 1 and 2 are successfully captured. However, no other inputs are heard. The Scarlett device also presents a very limited set of ALSA controls. exxothermic@exxothermic-BFC:~$ lsusb Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 002: ID 1235:8201 Focusrite-Novation Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub exxothermic@exxothermic-BFC:~$ amixer -c 1 contents numid=3,iface=MIXER,name='ADAT Validity' ; type=BOOLEAN,access=rw------,values=1 : values=on numid=4,iface=MIXER,name='Clock Source' ; type=ENUMERATED,access=rw------,values=1,items=3 ; Item #0 'Internal' ; Item #1 'S/PDIF' ; Item #2 'ADAT' : values=0 numid=1,iface=MIXER,name='Internal Validity' ; type=BOOLEAN,access=rw------,values=1 : values=on numid=2,iface=MIXER,name='S/PDIF Validity' ; type=BOOLEAN,access=rw------,values=1 : values=on I modified sound/usb driver files mixer_quirks.c and mixer_scarlett.c to treat the Scarlett 2nd generation device the same way it handles the Scarlett 1st generation 0x1235:0x800c 1st Generation 0x1235:0x8201 2nd Generation When checking with amixer, 228 controls are now listed, along with errors that prevent alsamixer from being used. I have no information about how to properly configure these controls. I am interested in any pointer to or information about how to configure and use this Scarlett 2nd Generation device.

OSC-generating plugin?

by Jörn Nettingsmeier

Hi *! Does anybody know of a decent free plugin that generates arbitrary OSC command streams from plugin automation data in the DAW? Preferrably (gasp!) VST? Idea is to use SomeEvilDAW to send and control smart things on a box running a friendly OS and a FriendlyDAW.

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

Does some proaudo stuff uses raw linux devices?

by Nikita Zlobin

Hello all. While configuring kernel, i stucked on option CONFIG_RAW_DRIVER, which enables /dev/raw device section. I suppose, things like linuxsampler or others, hardly working with storage, might utilize this access way for most direct access to samples. Or even in audio recording (only nearly imaginations). Is it so really? While searching in internet to learn about its real status, i got 2 facts: - When raw device is mapped to some hda/sda dev, allowing to use it even bypassing disk's internal cache. https://unix.stackexchange.com/questions/238798/what-happened-to-dev-raw - Yet i found proposal to remove raw devices support, argumented as these devices have no notable use. http://lkml.iu.edu/hypermail/linux/kernel/0505.2/1387.html (but that discussion is sooo old...)
