Hello!
I have an "Zoom R8" device - it is "audio interface" + "control surface" - all via USB. It works as control surface via midi. And it works on Ardour 3.5 and Linux mint 17.2 OK.
Device send midi messages - Ardour reads this messages and use them as control signals (as Mackie control device).
So i want to use Zoom R8 as control surface in kdenlive 0.9.8 BUT i don't know - how? In JogShuttle settings i see no devices. List is empty.
Moreover, i think that Zoom R8 in linux is NOT input device because

Code: Select all

cat /proc/bus/input/devices

shows NO Zoom R8. I think Zoom R8 is shown in linux Only as audio+midi interface, not input device.
Can kdenlive read control messages from midi device natively or i need some converter from midi to some input device?

To cut a long story short: a MIDI input device won't work in Kdenlive unless someone writes the necessary glue code for mapping MIDI data to Kdenlive actions, as well as the user configuration UI and code for configuring this mapping.

Kdenlive only supports a limited set of special-purpose (USB) input devices, handpicked by USB vendor and device identifiers. The rationale is that there is no way to tell whether any given input device will be suitable.

Thanks for answer.
I've suspected this way. But it is very strange way for kdenlive - many control surfaces use midi standard for that purpose for a long time. So why kdenlive doens't work same way that many other devices and soft?

Because the devs don't have these devices? You are free to help them out.

Maybe they dont have any midi control device (strange, but maybe). I'd like to know their opinion.
About help - unfortunately i dont have expirience in programming for linux (beside console "hello world") and not sure if i can do this "glue code". Maybe the best way - to get a part of code from Ardour source code and add it to kdenlive.
I'll think about it.
