MIDI Kinetics Forum

I cannot get bidirectional MIDI control working in my setup, and it's driving me nuts. I'm at my wit's end!

In case this isn't clear: if controlling a soft-synth, moving a knob on the iPad moves corresponding knob on-screen; however, moving knob on-screen with mouse does not move corresponding knob on iPad. :'(

I'm using the latest versions of everything.

Windows 8.1, 64-bit, Reaper, LoopMIDI.

I've got all the MIDI boxes checked in Reaper, to the best of my knowledge: Clock/SPP enabled, etc.

This is putting a severe hamper on my Lemur experience. What part of the puzzle am I missing here? I'll admit that I'm a bit of a noob with certain things and that perhaps I'm missing something simple here. But anyone who can help me will have my eternal gratitude.

Hello, this is a DAWspecific/VSTspecific issue you need to investigate but here are some basic guidelines to consider:

Generally speaking, you either map midi controls (Lemur) to functions-parameters of the DAW OR in the actual instruments-plug ins. Now.when mapped to DAW (levels, sends, etc) specifically in Reaper you ll have to create "actions" and in those actions specify midi in/out messages which in turn will provide the bi-directional feedback you are after. Its abit complicated compared to, for example, the midi mapping of Ableton Live where control and feedback are mapped with a "midi learn" function straight from the interface.
In the case of plug ins, either you map TO the plug in itself ( using the plug ins options) or, since every plug in exposes its parameters to the DAW, some DAWs give you a way to map " plug in parameters" whathever those may be per plug in - although I dont know if thats possible in Reaper.
One thing also to consider is that if you choose the first way ( mapping directly to the plug in) usually plug ins do not support bi-directional feedback. So the best way in all cases, is to find ways to midi map using your DAWs options - not your plug ins.
Search in Reaper's menu the Actions and create new action for, sayyy the levels of the tracks to get a feel of how it all works - and take it from there.

keep in mind you need midi input AND output active in Reaper. The output of Reaper should be connected to input of Lemur to have bi-directional feedback.

Hi thanks for your reply! I checked that out - triggering not the plugin directly but the reaper internal "action list" (checked out to move the master fader). That even works just one way and that is weird.

I have the same problem with OSC:
If I use a Behringer x32 with the x32reaper "translation script" of Patrick-Gilles Maillot, it works bidirectional. So OSC itself, the router or the computer cannot be the problem I think. I want to use lemur as a second OSC controller doing everything the x32 cannot do (has several limitations regarding OSC).
Of course, the x32 uses other ports and IP-address but how can that be. I just don't understand and need to get that work to finish my livesetup as soon as possible. Concerts are just around the corner.

Alright, I found out it's a Reaper Problem. Thanks for helping.

That's great, GnK.

How about posting how you resolved the problem in Reaper, for those of us who might have a similar issue?

Not trying to flame you, but after all, isn't that what forums are all about?

Thanks in advance, guy.

well, reaper just cannot learn both ways yet.
