Configure/Knob edit mode, as to avoid abrupt changes upon

editing values (still the default behavior) and only take

effect (Deferred) when enter is pressed or the spin-box

loses focus.

- The main GUI has been partially revamped, after replacing

some rotary knob/dial combos with kinda more skeuomorphic

fake-LED radio-buttons or check-boxes.

- Alias-free/band-limited wavetable oscillators have been

fixed to prevent cross-octave, polyphonic interference.

dialogs option is now set initially off by default.

the configure build date and time stamps.

atom notification event, as far as to give some careful

hosts enough slack to raise a dirty flag.

- Almost complete overhaul on the configure script command

line options, wrt. installation directories specification,

eg. --prefix, --bindir, --libdir, --datadir and --mandir.

0.7.5 2016-06-16 The Tenth official beta.

- All changes to most continuous parameter values are now

smoothed to a fast but finite slew rate.

- All BPM sync options to current transport (Auto) have been

refactored to new special minimum value (which is now zero).

cached parameter values only, via shadow ports, instead of

input control ports directly, mitigating their read-only

restriction.

- Make sure LV2 plug-in state is properly reset on restore.

- Dropped the --enable-qt5 from configure as found redundant

given that's the build default anyway (suggestion by Guido

Scholz, while for Qtractor, thanks).

- Fixed the DCF Formant filter voice initialization reset.

0.7.3 2016-02-22 The ninth official beta.

with LV2 plug-in hosts that feed/run them in on border line

circumstances (as reported by Thorsten Wilms, on suspected

Ardour looping crash/bug, probably fixed already, thanks).

- Safe defaults are tentatively sbeing introduced to internal

OUT FX buffer-sizes, as read from JACK buffer-size changes

and LV2 block-length instantiation bound options.

- Added application keywords to freedesktop.org's AppData.

0.7.2 2015-12-04 The eighth official beta.

- A brand new LFO BPM control parameter is being introduced,

transport/host option (BPM=Auto).

- A fourth DCF type has been added: a vocal Formant filter.

- A third DCF slope/type has been added: the RBJ's bi-quad.

- Prefer Qt5 over Qt4 by default with configure script.

- Introducing brand new OUT FX Send parameter per engine.

0.7.0 2015-07-24 A seventh official beta.

- Complete rewrite of Qt4 vs. Qt5 configure builds.

- Reset ramps after LV2 control port reconnection; small fixes

to LV2.ttl (pull-requests by Hanspeter Portner aka. ventosus,

thanks).

- MIDI Controllers/Programs is now an optional feature on the

LV2 plugin forms, as some LV2 hosts might enforce the purity

restriction to input control ports as being absolutely read-

only parameter values from a plugin's instance perspective.

- MIDI Controller mapping/learn is now possible on all parameter

control knobs; with global configuration also avaiable on the

Help/Configure dialog.

- French (fr) translation line to desktop file added (by Olivier

Humbert, thanks).

- Main widget layout changed as much to expand or grow vertically

as needed.

0.6.2 2015-04-30 A fifth official beta.

0.6.1 2015-03-09 A fourth official beta.

- Added application description as freedesktop.org's AppData.

- Introducing LV2 port-groups (as proposed by Amadeus Folego aka.

badosu, thanks).

- Improved envelope widget nodes click-and-drag precision.

- Introducing a brand new user preference on eye-candy: cf.Help

/Configure.../Options/Custom style theme (applies to the JACK

stand-alone client only though).

new MIDI bank/programs interface and user preference options

as well (new home of the old Help/Use native dialogs option).

- Presets may now be specified by base name, as an alternative

to the complete preset file-path on command line argument (re.

stand-alone JACK client).

limited treat option and re-labeled as 'Rand'; also a brand

new wave-shape 'Noise' is then introduced (now for real :)).

- New user preference option, cf. Help/Use native dialogs.

- An anti-denormal regression applied to the Phaser fx stage

(affecting early proto-beta >= 0.4.0).

0.4.1 2014-04-07 A proto-beta bis.

- Once so called 'Noise' wave-shapes are now being made a lot

more deterministic, read idempotent ;).

- Fully alias-free/band-limited wavetable oscillators are now

in place, making it a better virtual-analog synthesizer (esp.

for running sample-rates below 96KHz).

- Late optimizations to basic wave-table oscillators.

- Make sure the LV2 plugin back-end always builds first, before

its respective LV2 UI front-end client.

0.4.0 2014-03-06 A proto-beta party.

- All knobs default value setting slightly improved.

to when NSM session management is in charge: the native file

browser/requester dialogs are then disabled (were taking too

long to list the current directory on first time invocation).

LV2 plugin, whether it may be .../lib or .../lib64 on bi

-arch targets, when libdir is not specified on configure

- A brand new icon drops the lamest old-schooler's out, in a

master lesson taught by Jarle Richard Akselsen, thanks.

0.3.3 2013-05-31 Late spring blossoming

- Some sympathy to extreme dark color (read black) schemes is

now being indulged; some discrete changes on the icon front

has also emerged ;)

recognized, in addition to MIDI channel pressure/aftertouch

processing.

- Parameter value ramping moved into the late post-processing,

an attempt to reduce some pop/click artifacts even further.

- NSM support introduced to JACK client.
