Greetings,
  one second time!
  The 'Vee One Suite' of so called 'old-school' software instruments,
synthv1 [1] as a polyphonic subtractive synthesizer, samplv1 [2] a
polyphonic sampler synthesizer, drumkv1 [3] as yet another drum-kit
sampler and padthv1 [4] as a polyphonic additive synthesizer, are all
here and now released, making it for the second QStuff* Winter'19 batch
of the season.
  All delivered in dual form:
- a pure stand-alone JACK client with JACK-session [5], NSM (Non Session
management [6]) and both JACK MIDI and ALSA MIDI [7] input support;
- a LV2 instrument plug-in [8].
  Changes for this special season are pretty much the same for all the
'gang-of-four':
- Custom color (palette) theme editor introduced; color (palette) theme
changes are now effective immediately, except on default.
- Second attempt to fix the yet non-official though CMake build
configuration.
- Move QApplication construction/destruction from LV2 UI to plug-in
instantiation and cleanup.
  The 'Vee One Suite' are free, open-source Linux Audio [10] software,
distributed under the terms of the GNU General Public License (GPL) [11]
version 2 or later.
