Midi reactive / jit.gl.camera

Hi.

I play an organ with an upper and lower manual transmitting midi on CH1 (upper) and CH2 (lower) note and velocity.

I want to use the midi values to colour 2 shapes (jit.gl.gridshape) - 1 shape for left hand and 1 shape for the right hand. That works fine.

However - I want to combine this with some beautiful point lights like in the "point light" example from GL3-launch.

I managed to route the shader to my shapes but I had to duplicate Jit.gl.camera in order to make it work......but this also duplicated the shapes. :-( and also the jit.gl.gridshape "plane" receives now midi values and gets coloured what I do not want.

Thanks in advance for any help.
