QTQuick - QML - Javascript - Midi

[frasene]

Hi,

I am very interested to make a program (for Symbian^3) using QTQuick and particulary Javascript and QML (but not C++)...

Is it possible to send real time midi events (like "note on" / "program change") with only Javascript ? Is a Javascript library is included into QtQuick to play with realtime midi (not just playing a midi file) ?

With J2ME it is possible so with QtQuick ?

Thanks

Having worked strongly for more than ten year on coding midi/audio sequencer software on Win32 ,let me say there is not chance to build realtime midi playing by javascript .. i mean realtime ... you can send single message , if you like , for example click a button in Qml , route the event Qt multimedia layer , and send the message to the midi output will work with some latence , of course you cannot play Chopin midifile

QML also provide Audio element to play audio file under Multimedia QML Plugin. QML elements are nothing but the wrapper on qt and Symbian. You can also write your own wrapper to do so.

Thanks for your answers and advices...

My purpose is just to play scales and chords like doing eartraining things...

So no javascript library to send note on midi event... So I have to write I suppose a library in C++ used in javascript... In C++, does a library exist to control midi synth ?

Bye
