If you have trouble importing a file (e.g. mp4), you could review:
which amounts to trying this: sudo apt-get install ubuntu-restricted-extras

I hope you will get as much fun playing with it as I do.

VIDIFOLD Revision Notes

A list of all the notes from all versions is provided below.


quite a large change and update to GUI layout
split global hotcues into a/b bus versions
click on macro panel for running aux to access driver options
- might change how the aux rack select/trigger behavior later, but this was a good work around for a minor problem
shift + click bug was always starting clip, now on non-playing slot just selects
redesigned slot panel preview and transport controls
added local speed multiplication controls


Moved snapshot button into slot action menu
Moved plugin action menu to left for easier access
Shrunk plugin level control and included a popup
Replaced FX all on/off buttons with FTG (FX toggle all option)
Added plugin Hotcue option to plugin
- played with having up to 4 but it wasn't worth it, where single one did the job
- and keyboard control LEFTALT + F1-F8 to trigger
- and LEFTSHIFT + hotcue to clear
Added a Stack HotCue option

Fixed 4LY behaviour for Aux Rack
- aux slots were stalled while layer wasn't active

More space used to toggle layer modes for touchscreen
- moved mix/simple mode button to overlay
