In 1908, Hugo Popper in Leipzig launched the reproducing instrument “Stella”. Technically it is very similar to the Welte-Mignon. The roll width and scale, however, are different. We are currently restoring one of the very few surviving Stella pianos and are also creating technical records in the process, as no documentation on this instrument has been found to date.
The scale of the Popper Stella system has 114 holes in the tracker bar.
