Correct.  Multi-instance worked, but it was a pain.  Currently, number
of voices is set at compile time, so be sure to run configure with
--enable-parts=4, or however may parts you want to use.  More than two
parts per CPU core is not currently recommended, however.

I had already implemented this as the "Notes Off" button before reviewing
Anton's work.  This probably should be renamed.

Unfortunately, I haven't got around to implementing LFO sync with the MIDI
clock yet, so there still may be some drift.  This MIDI clock currently
handles event timestamping and MIDI/audio/engine thread synchronization,
and does not yet handle phase sync.  If you're running on a fast 64-bit
processor, you can get better precision on the LFOs with a pure 64-bit
build (--enable-cpu-power=4).

Try v0.14.97-dev in git:

git clone -b v0.14.97-dev https://github.com/williamweston/phasex.git

I haven't been able to verify the jack1 fixes yet, but I'm very hopeful.
