leap motion patch creation

[Shintylla]

Hi,
I'd like to create a patch in which I can assign midi parameters to leap motion outs (fingers pos, palm position ecc..) Is there a tutorial/instruction in which is explaned how to commute values from Leap's module to the desired ones (ex.:MIDI; switches; ecc..)
Thanks

I believe there are some posts already in the forum, and I think I have some patches shared in there for XY to controllers you can reference. I dont know if there is a Leap to MIDI tutorial though.

Let me know if you cant find the posts and ill see if I can dig up the patches.

Thank you sephult, I'll tell you. This morning I'll digged a little in the forum but I didn't find specific posts. Anyway my aim is to learn how to instead of copy-paste things

[sephult]

i completely understand, but maybe you can reverse engineer a bit and at least see what is done. Will have to be some more documentation for things coming soon. Also dont forget we have a wiki that can be edited. If you learn something share

Leap


Try this, I had built a way to recognize independent hands and controlled MIDI CC.
Check for further in post, I might have updated as I went.

Here a basis example for the left hand and X axis, the leap module outs array , these arrays send 0 to 1 values,
So here i multiply this value by 127 to have a classic 0 to 127 Midi values
this value is send to the code 2 of a create MIDI module
here the CC number is 10
The has changed module create this MIDI message each time he receive changes



ok, crossed post with sephult

Many thanks to both

Sorry, I might making some mistakes but I can't make it work. Can you explain how are code 1 and 2 and how it works to get midi output?
I uploaded a wkp called leapXaxisToMidi. Can you see if something wrong?
Many thanks

Which type of message do you want send, note or control change ?
if note, code 1 is the note number, code 2 the velocity
If control change, code 1 is control number, code 2 is value

this means on your workspace, you send note 128 with different velocity on canal 2 ?

Note with right hand y axis.

Do I have to cable create midi patch midi output to vsti midi in or code 1 output to midi in?

[nay-seven]

ok, so in your first workspae, if you inverse code1 and code 2, must work , code 2 for velocity will be fixed , or maybe you can use another leap value ?

some tips, add a quantize data module before code 1 to not have continues notes, and maybe a MIDI make monophonic module after the create MIDI module to create notes OFF

And yes, create midi patch midi output to vsti midi in

[Shintylla]

I met a problem. Value out of array surpass 1 and some peaks reaches 1.1/1.2. This 'cause unexpected sounds out of the vsti. I also don't notice anything new without make monophonic.
I don't want to buy a leap to midi plugin. The patch just give me ugly sounds ..
Any help?

maybe just clamp to 0.1? to clamp either add a "clip array" before the array or a fader with 0..1 range after you take the pin out

[nay-seven]

yes patching in Usine need to experiment a lot, you say you want to learn ?

here an update patch from where you start, I've add change scale modules to avoid your issues and quantize data
also add a send note OFF

And here the leap piano (in the Usine browser) adapted to a vsti

thanks
best support overall!!!!
