1 – Introduction
The 2.0 series of EigenD is the first to include the Workbench, a graphical utility for
manipulating and examining setups. Workbench is part of the EigenD Pro distribution.
The official documentation for EigenD 2.0 can be found on the wiki:
http://www.eigenlabs.com/wiki/2.0/The_Official_Documentation/
As with the 1.4 release, the core elements of 2.0 are built from the open source EigenD
repository which can be found on github:
https://github.com/Eigenlabs/EigenD
Starting from 2.0, we are dropping support for Mac OSX 10.4 EigenD now requires
Leopard or newer. Make sure that you have applied all the Apple updates to Leopard, this is
needed for the EigenD installer to work.
Many aspects of EigenD have changed. In the past, quite a few functions depended on the
Belcanto interpreter to work. Most of these have been re-architected so that they are more
intuitive in a GUI environment, while retaining the ability to configure every aspect of
EigenD using Belcanto. As such, existing setups and scripts from EigenD 1 aren't
compatible with EigenD 2.
We are now skipping odd release numbers to allow for intermediate test releases.
In the past, when factory setups have changed, we have automatically upgraded saved
versions of these setups in line with the changes made to the factory setups. Because of the
huge scope for customisation offered by Workbench in 2.0, we will no longer be doing this.
Now that 2.0 is stable, there will be no changes which will invalidate saved setups. If we
make any changes to the factory setups (for example, changing the plumbing between
Agents) we will provide upgrade scripts which you can run to make the same changes. You
can also use Workbench, if available, to make equivalent changes to your own setups.
EigenD 2.0 will now receive bug fixes only, development will continue with 2.1.
2 – New features
Workbench
EigenD setups can now visually be created, modified and inspected using the Workbench
tool. It provides a graphical environment in which agents can be easily edited, configured
and connected. This makes it very intuitive to create totally customised setups or just to
make a quick variation on an existing setup. All changes made in Belcanto are instantly
visible in Workbench and vice-versa.
With EigenD being available for public performance, Stage for private performance and
Workbench for private rehearsal, all phases of musicianship now have a dedicated, carefully
designed, integrated tool for the Eigenharp.
The major features of Workbench are:
•
•
•
•
•
•
•
•
•
•
streamlined and friendly graphics with dangling wires that can nicely be arranged
through trunks and hooks
high-level agent view with details of each port when they're expanded
vector-drawn scalable graphics
tool-driven workflow with keyboard shortcuts for quick operations
agents can be encapsulated into rigs with their own panel for clear organization
general purpose editors to configure agents
custom-designed editors for configuring options
smart visualisations to make it very easy to understand what is connect together
intelligent visual focus to fade-out agents that you're not working with
built-in documentation of each agent and its ports
You can find a full reference documentation of the Workbench on the wiki, including a
series of tutorials that take you step-by-step through the creation of your own setups from
scratch with Workbench:
http://www.eigenlabs.com/wiki/2.0/Workbench/
Fingerer
This release introduces a new Fingerer agent which simulates valved or fingered
instruments.
It allows groups of keys to be fingered in monophonic fashion, while harnessing the
sensitivity of the Eigenharp keys to produce interesting effects. It also provides additions
that still allow for polyphonic playing.
Fingering patterns are very flexible, and you can create your own patterns and copy and
modify the factory patterns. The Fingerer documentation can be found on the wiki:
http://www.eigenlabs.com/wiki/2.0/Fingerer/
Fingerer ships with a series of factory fingering, which include:
•
•
•
•
•
simple whistle
tin whistle
basic clarinet
saxophone fingerings
more experimental ones for the adventurous players
Illuminator
The Illuminator agent is also new in this release and provides an easy way to set up lighting
patterns on the Eigenharp keyboards.
You can use the keyboard to capture patterns. Patterns can be saved and loaded through
Belcanto for instant recall via Talkers.
The Illuminator also provides a web interface allowing you (or someone else, preferably!) to
post scrolling messages to your keyboard. There's a network interface available for
programmers who are interested in creating custom applications for Illuminator.
Its documentation can also be found on the wiki:
http://www.eigenlabs.com/wiki/2.0/Illuminator/
Strummer
The Strummer agent is the third major new agent in the release. It allows one set of keys to
act as 'strum' keys for another set of keys which act like strings, controlling the note to be
played.
Like a guitar, effects such as hammer-on and pulling-off are possible as well as
straightforward strumming. Sounding notes can be muted, and there is support for open
strings. A breath controller can also be used as the strum input.
Strummer's documentation can be found on the wiki:
http://www.eigenlabs.com/wiki/2.0/Strummer/
Other improvements
Many improvements have been made throughout the entire EigenD system, these are the
highlights:
Audio
•
•
•
Support for multiple channels, as well as incoming and outgoing audio.
Improvements on MacOSX to permit very small buffer sizes.
Clocking has improved, reducing overall latency with certain audio devices and
buffer sizes.
AudioUnit/VST
•
•
•
•
•
•
•
Multi-timbral support for using host automation parameters to provide expression
capabilities that surpass the limitations of MIDI CC.
Pitch-bend calibration to precisely match up the pitch-bend capabilities of plugins
with the frequencies used in EigenD.
Detailed documentation about how to use these new capabilities:
http://www.eigenlabs.com/wiki/2.0/Configuring_AudioUnit_and_VST_plugins/
Improved handling of tail-time idling, allowing it to be directly turned on or off.
Clearer plugin lists that now includes type and category.
Better compatibility with different plugins.
Stability improvements regarding shutdown for certain plugins.
Belcanto
•
•
•
•
Improved number handling, allowing for instance direct setting of scales through
Belcanto, without having to define and name them first as user scales.
New 'identify' verb to gain visibility into which agents Belcanto is addressing.
Easier configuration of Talker, Scheduler, Arranger by using 'do' verbs
Support for talker re-do, making it much easier to dynamically change talkers based
on variables.
EigenD
•
•
•
•
•
•
•
•
•
•
•
•
New geometrical and musical layout for keys throughout the entire system. This
allows talkers to for instance remain at the same position while the musical position
of keys can be freely rearranged.
Reworked lights throughout the system to work together with the geometrical and
musical key information.
Volume ports in Console Mixer now use dB ranges from -70 to 14.
Keygroup outputs can be slaved together to automatically enable/disable them at the
same time.
The scaler agent automatically colours the tonics in green and changes them
accordingly when new scales are selected.
Experimental support for OSC output, with bare-bones setups for each instrument.
The Convolver agent is now more tolerant of different Impulse Response files,
making it useful as a general convolution engine.
Keygroup outputs can now be individually toggled or enabled.
The 'return' and 'escape' keys now properly confirm/cancel throughout the
application.
Streamlined handling of connection channels, making it more intuitive to select the
channels that are being used by a particular connection.
New Player agent to play notes, extracted from the Recorder agent.
Better support for international home directories on Windows, allowing EigenD to
run for user names with international characters.
Instruments
•
•
More efficient startup behaviour.
Configurable Alpha and Tau de-bouncing system, allowing keys made out of wood
•
with a higher friction coefficient to behave more precisely.
Improvements to mode key lights on the Pico.
Memory and performance
•
•
•
•
Overall reduced memory usage.
Windows machines now also have access to 4GB of memory.
Reworked memory allocation for better stability and performance.
Much improved incremental setup loading, allowing faster and more stable switching
between different setups.
MIDI
•
•
•
Available MIDI devices are now updated while EigenD is running.
Improvements to MIDI input, allowing a MIDI foot pedal to for instance trigger
talkers.
Automatic connection of previously selected MIDI devices even when they're turned
on after EigenD.
Stage
•
•
•
•
Tapered faders and knobs for volume control.
More reliable widget updates.
Better default widget increments when they're dragged onto the canvas.
Easier to use agent browser when creating custom Stage tabs.
Developers
•
•
•
•
EigenD includes enough headers and import libraries to build Agents without
needing the full source.
Agents now occupy relocatable directories.
Agents can be packaged and distributed or sold individually with appropriate standalone installers.
New contributor area on GitHub with build scripts that make it easy to get started
when developing your own agents: https://github.com/Eigenlabs/EigenD-Contrib
3 – Bug fixes
•
Release 2.0.68-stable
◦ EigenD
▪ AU/VST/MIDI pitchbend is now being sent before note on, instead of after
since it's otherwise often interpreted as a fast pitch change after the note
started.
▪ The download link to go to a new version of EigenD now differentiates
between the Standard and the Pro version.
▪ Improved compilation settings for non MacOSX Leopard builds.
▪ EigenD could become unresponsive on Windows when tapered Stage widgets
when to their minimum value.
•
Release 2.0.66-stable
◦ EigenD
▪ MIDI input and output ports would sometimes not correctly restore to the
ports that were saved in the setup.
▪ Pico Factory 1 and 2's talkers didn't allow you to browse for certain
instrument AudioUnit/VST plugins. The factory setups themselves have been
updated.
The scripts 'Pico Factory 1 – 2.0.64' and 'Pico Factory 2 – 2.0.64' from inside
the 'Factory Setup Fixes' can be used to fix existing setups that were based on
the factory setups.
▪ EigenD would still fail to run in some situations for user home directories on
Windows with international characters in the path.
▪ Belcanto fixes to allow numbers inside the names of agents.
▪ Belcanto fixes to better disambiguate agents in certain situations where one
doesn't have an ordinal and others do.
▪ Fixes for MacOSX Leopard.
◦ Workbench
▪ Stability improvements regarding the creation and manipulation of channels in
Agent boxes.
▪ Browse editor now indicates when there are no choices available.
▪ Trunk and hooks could go underneath agent boxes with wires still on top.
▪ Boxes can now be moved automatically multiple times when above Agents are
expanded and correctly restore their position afterwards.
▪ Floating point editors don't show unnecessary decimals anymore.
▪ Per-agent lexicon words weren't correctly picked of by Workbench.
▪ Improvements to wire drawing inside trunks.
•
Release 2.0.64-stable
◦ EigenD
▪ Fixes to Recorder agent play verb which wouldn't execute through Belcanto.
▪ Fixes to shutdown and setup reloading, specifically for AU/VST plugins.
▪ More reliable reloading of AU/VST plugins when the audio sample rate
changes in EigenD.
▪ Properly set the title of a MIDI Convertor Agent window to indicate the rig it's
part of.
▪ Properly fall back to the default audio device when the configured audio
device doesn't exist.
▪ Improvements to audio device, sample rate and buffer size selection.
◦ Workbench
▪ Stability improvements regarding certain mouse movements and tool
selection.
•
Release 2.0.62-stable (since 1.4.12)
◦ EigenD
▪ EigenD could sometimes becomes unresponsive at exit, this has been
improved. Note that this is often related to AU/VST plugins and in certain
cases there's little we can do about this. Closing the plugin GUI before
quitting can sometimes help.
▪ Certain AudioUnits could crash EigenD when deleted while their GUI
window was still open.
▪ The delay inputs of the ADHSR agent was not functional.
▪ EigenD now works with user home directories on Windows 7 that have
international characters in their name.
▪ Stability improvements for AudioUnits destroy at close and EigenD shutdown.
▪ MIDI note 0 wasn't sending a note off message.
▪ Fix to audio device handling where the current buffer size wasn't always
determined correctly, especially with ASIO devices.
▪ The Pico mode key lights could sometimes be wrong.
▪ Loading a new setup while another setup wasn't finished loading could put
EigenD into an inconsistent state.
▪ The MIDI routing matrix now doesn't use 0 for the return to origin
functionality for the pitchwheel mapping, but uses 8192 instead, which is the
rest value for pitch bend.
▪ Stability improvements to AU/VST host
▪ Stability improvements to Midi Converter
▪ Tempo ranges from 0 to 500 are now accepted in the metronome, as opposed
to 30-240 before
▪ Setting delay agent tempo to 0 crashed EigenD
▪ Setting ladder filter agent temperature to 100 made it stop working
▪ Stability improvements, especially with respect to switching setups
▪ Changed installer test to copy better with symlinks and improve Lion
compatibility
▪ The MIDI input agent wasn't properly handling CC messages.
▪ AU/VST and MIDI routing matrix parameter 16 isn't a special 'key number'
parameter anymore, functionalities relying on this should use talkers instead.
▪ Fixes to bug reporter
