The objects separated would be confusing for me, how do i read in and out notes for example, i just would not know howto even start approach howto read in and out something from such a hierarchy.

Here is how i would work store data into my favoured structure of "made up" object

But how do i implement it, i do not understand the object syntax well enough to create it.

synth[i].synthname="Roland D50";

synth[i].bank[x].bankname="Base & Drum";

synth[i].bank[x].instrument[y].instname="Trombone";

synth[i].bank[x].instrument[y].note[z].notename="HiHat";

I am totally clueless how to implement this object though, but the way it accept data make sense to me?

Because such an object is possible to create or?

Syntax to create the object above please??????????????
function newCollection(m) { 
  synth[m] = { 
    synthname : "", 
    bank[]={ 
       bankname : "", 
       instr[]={ 
          instname :"", 
             note[]={ 
                 notenname : "", 
                         } 
       } 
    }           
  }; 
  return extSynth; 
}
