I'm pleased to announce the release of Non-DAW and Non-Mixer version
1.1.0. It's been a while since the last release. But, I assure you,
the project is still alive and well.

This release includes a number of fixes and some minor improvements to
the build system. The big changes are:

* Enhancements to the spatialization controls (which are automatically
  provided for Ambisonics plugins).

* Support for the Non Session Manager.

* Enhancements to Control Sequences, OSC control signals can be sent
  from Non-DAW to Non-Mixer. These connections will be preserved in
  the session.

* Non-Mixer accepts input for all Module/Plugin controls via OSC.

* Non-Mixer can now import and export individual strips (including the
  chain of modules and all their parameters!) This allows a workflow
  on a higher level than presets.

* Updated visual styles for both Non-Mixer and Non-DAW. The 'Flat'
  style has been greatly improved.

* New knob styles for Non-Mixer and knob style is a configuration
  option rather than requiring editing the source.

* New icons in an assortment of sizes.

Additionally, Non now supports a robust new session management
protocol called NSM. A session management daemon is provided along
with a graphical interface called Non-Session-Manager. NSM represents
a significant leap forward for session management in Linux audio.

:: History of NSM

Way back in 2008, I became frustrated with the state of the art of
session management on Linux (a situation which has improved only
incrementally since that time). I ditched support for LASH, wrote a
lengthy post about Non-DAW's session management requirements to the
LAD mailing list, and started managing my sessions with shell scripts
and jack_snapshot. This eventually evolved into a session manager
written in Unix shell and using Unix FIFOs and regular files for
client control/communication. This system of session management was
tentatively called NASH (Non Audio Session Handler) and was never
released. In 2010, shortly after the release of Non-Mixer, I devised a
prototype version of the NSM OSC API and have been using it, still
unreleased and in prototype form, since then. The 2010 implementation
did not have a user interface and was controlled via shell scripts
using the `send_osc` command included in the distribution. Then, in
2012 (4 years later!), I was contacted by an enthusiastic power-user
regarding implementing OSC support in Non-Mixer. Since NSM uses OSC
for server<->client communication, I already had much of the OSC work
done and figured I might as well release it--and, while I was at it,
NSM. I then endeavored to simplify and document the NSM API,
discussing it at length with, and taking many suggestions from, Nedko
Arnaudov, the LADISH author. After implementing the
Non-Session-Manager FLTK GUI to control the session management daemon,
a new release became inevitable.

:: Bullet Points for NSM:

* Extremely fast and responsive control mechanism and user interface.

* The only dependency for clients and server is an OSC library (I use

* Smart clients are able to switch projects without restarting.

* Clients can provide real-time status feedback to the server, and
  therefor the user.

* The server stores all session data in per-session directories under
  a configurable session root.

* Clients are forbidden to save or open files outside of the
  per-session directory.

* The server provides simple template support in the form of
  whole-session duplication.

* The Session management daemon is fully controllable via OSC.

* Strict user interface guidelines for a uniform and predictable

* The abstract session management API has no architectural requirement
  for JACK, Xorg or any other subsystem (other than UDP
  networking). This means that both headless daemons and programs
  which are not JACK clients can be managed together in the same

* A single session can be distributed across multiple machines on a

* Multiple, independent, sessions can be opened on one machine at the
  same time.

NSM is included in the Non-DAW/Non-Mixer repository.

:: Ongoing and Future Development

Features that are in development for future releases include an
auto-learning and graphically re-mappable JACK MIDI<->OSC gateway
program tentatively named Non-OSC-MIDI-Mapper, which will simplify the
connection of bidirectional control surfaces such as the BCF2000 to
Non-Mixer. This program relies on Non's generic Control Signal layer
on top of OSC. So it's not necessarily generally useful (although, in
the future, it may be possible to use the `libmapper` library to
provide the same functionality in a somewhat standard way).

LV2 support is a frequently asked question. For various reasons, I
currently have no plans to host LV2 plugins in Non-Mixer. But if
anyone can come up with a compelling argument for LV2, or name one
existing (libre) LV2-only plugin which couldn't be ported to LADSPA in
a few hours that I couldn't live without having in Non-Mixer--I'd love
to hear about it.

I plan to re-factor Non-Sequencer to use the `nonlib` library common
to Non-DAW and Non-Mixer. This will eliminate some duplicated code and
allow for some of the user interface improvements seen in Non-DAW to
be implemented for Non-Sequencer. It will also enable various forms of
MIDI support in Non-DAW/Non-Mixer (it's not clear yet what forms this
support might take.)

Similarly, by using nonlib, OSC will be available in Non-Sequencer,
probably taking the form of OSC control for pattern triggers and
possibly pattern input. Also, with NSM's 'broadcast' capability, the
holy grail of a shared tempomap is closer than ever.

Another long-term goal for Non-Sequencer is to make the interface more
compatible with touchscreen use, which I am better equipped to tackle
now that I have a tablet like computer to play with.

A near term goal for Non-Mixer is to add an option to that causes all
mixer strips to run in a single JACK client. Conceptually, this is a
horrible idea, but due to some practical performance limitations of
JACK which affect users with hundreds of mixer strips, it may be a
necessary evil. Leave it to JACK to design and advertise a feature
(multiple clients per process) and then turn around and antagonize the
people who actually use it.

:: Project Notes

Please keep in mind that the Non project is a one man show. I designed
and implemented all of this stuff by my self, and at a considerable
cost in time, sleep and energy. I make it available to you so that you
can be free of the enormous burden of having to solve these complex
problems yourself. I see chatter on various forums about forking the
project, the project being dead, etc. Unlike some of the more
heavyweight projects out there, Non has no corporate sponsor, and I
have a complicated and turbulent existence which does not always allow
me to devote my attention to purely intellectual pursuits. I welcome
any and all contributions, whether they be in the form of code,
documentation, testing, package maintenance, chocolate, roses,
precious metals, priceless relics--whatever. If those who bring up the
issue of forking really had the skill and energy required to do
something better with Non-*, you'd think they'd at least try
submitting a few patches to me first...

I run Debian GNU/Linux and Non-* use a made-from-scratch custom build
system which relies on accurate information from pkg-config. I cannot
test on, or anticipate the quirks of, the hundreds of other Linux
distributions out there. I have a policy of never committing code to
the Non git repositories which does not build. Thus, if you are having
a problem building Non on your system, chances are it's just because
of some silly/simple quirk of the distribution you're using that could
easily be fixed. However, I'm not going to scour the web looking for
these reports. Unless you send a report to the appropriate Non-*
mailing list, expect that your issue will never be resolved. As
always, the best and fastest way to get anything fixed is to just fix
it yourself and sent me the patch--preferably with a thorough
explanation in the commit message of why it is needed and how it
works, as the less time I have to spend reviewing a patch, the quicker
it will be applied.

And finally, a note to packagers: If you feel that there's something
about Non's build system that you don't understand or feel like you
have to hack around, please consider discussing it with me. I'm more
than willing to make changes to the build system which make life
easier for packagers and improve the quality of packages. Having flaky
builds of Non-* in a distribution's packages isn't good for
anybody. I've seen comments in distributions' packaging bugtrackers
saying that Non is a dead project, that the "developers" (plural) are
unresponsive etc. But I've never heard from these people. If they
actually took the time to email me, they might have different

:: Errata

I do not recommend linking Non-DAW against FLTK 1.3.0. FLTK 1.3.0
introduced a number of bugs, one of which seriously impairs Non-DAW's
graphics performance. Non-Sequencer and Non-Mixer do not use the
features of FLTK that have become buggy, so if you only plan to use
them 1.3.0 should be fine. 1.1.10, 1.1.9, and 1.1.7 work fine,

In the future, I'll be maintaining a known-working version of FLTK
along with the Non repository so that Non-* can be statically linked
to the custom FLTK and avoid problems like this--and also allow many
workarounds used by the Non-* programs to be removed in preference to
fixing them at their source.

If you decide to build FLTK yourself, don't forget to use the
following configure options:

--enable-threads --enable-shared --enable-xft --enable-xdbe
