Musical Instrument Factory of Riga (Latvian: Rīgas mūzikas instrumentu fabrika — RMIF) was the largest Soviet electronic music instrument manufacturer.
RMIF synthesizers became very popular among rock and pop bands in Eastern Bloc.
Until 1999, about 20,000 "Rīga" pianos were produced at the Riga Musical Instrument Factory.
In the markets of the USSR and vice versa, Latvia imported pianos from other republics of the USSR ("Belorusj", "Krasnij Oktyabrj", "Ukraina", "Moskva", "Akord", "Lira", etc.).
One part of the musical instruments was eliminated in the course of operation.
