Just noticed about this recent release of JUCE 1.10:
You might remember then, that I've brought this
very subject into
attention to the Linux Audio Developers and USers (LAD/LAU) mailing list,
and to put a long story short: help is being here reiterated to write the
native Linux Audio and MIDI implementations of the JUCE C++ framework,
which among other things, may bring a native Tracktion Linux port into
light :P
and if a developer adds native linux audio/MIDI to JUCE, they will still have to pay for
the linux version of tracktion, no?
