just been looking at the structure of the original project.. have not changed much.. only that para elisa is now on a loop and each time a different "synth font" representing midi voices that are available in 1.4 should be used. ("anvil studio has about 128midi voices" amd linux multi media studio has an infinite range of synth fonts and ways to create sampled fonts..sort of..--- i am not a sound engineer..but just to say that voices seem a bit limited in the midi synth font sound block menu in scratch 2.0..so far..)
