[PD] tvjt - a vj tool

Hi - erm, hard off :-)

yeah, definitely. I think this can be done by changing
the visibility of the individual renderchains, and
those changes can be triggered by metros (periodical
bangs) - so this should be possible within the current
framework.
There will also be a cheap sampler - ie., you can
internally capture your output and feed it back to
tvjt.

beat detection is already there, and so is processing
of external midi signals. these events trigger bangs
that in turn trigger envelope generators, it is
possible to adjust each and every aspect of a render
chains with these values.
I'd love to add more audio-related stuff, but I'm not
exactly an audio guy and don't have much of a clue int
his respect ... I'm using bonk for the beat detection,
which works great. There is some sort of treble
detection as well, which is more or less reliable
(basically it's a hip~ that triggers a bang if a
certain threshold in the amplitude is exceeded). If
you have any suggestions on more audio feature
extraction, I'd be glad to implement them :-)

there will be some sort of an api, I'll also document
the internal message structure so it should be
relatively easy to add more filters etc.
and it would definitely a good idea to add an input
for external sources. that should be easy enough, it's
merely a matter of importing a gem render chain. I
actually talked to Ben Bogart about this, maybe we can
settle on some sort of quasi-standard that would allow
to share stuff across different gem applications.

thanks & with kind regards,
thoralf.
