Soon Giacomo is helped in his art by three sons: Bernardo, Gaspare and Anacleto. Together they built several new instruments providing them with spring chests and mechanical actions in accordance with the classical Italian style of the period. After Giacomo it was time for his grandson Vincenzo to take over Mascioni's business. Thanks to his ability Vincenzo grew the firm not only in size but he also developed new working processes: forward-looking hydraulic machines were introduced. Transmissions became pneumatic, and the music that flowed out the new kinds of pipes sounds romantic and appealing for the Central European taste.
 

Throughout the 30s the firm specialized in the production of electric transmission organs and patented several technical devices (some are still in use for new consoles such as the special device which gives a pleasant key-touch).
Soon Mascioni's prestige spread out of Italy thanks to the manufacture of several instruments commissioned from Switzerland, Malta, etc. Through the 50s the firm Mascioni built even 16 organs per year, some of which were quite large instruments provided with four or five keyboards.
