Here is Bach's Ein Feste Burg Ist Unser Gott performed on the GPO pipe organ. For the manuals I used Full Organ, Haupt Mix and Cornets. For pedal I used Baroque Plen Reeds and Baroque Plenum. Reverb is SIR.
For Fabio and David. I might be old as the hills but I can learn new tricks. Here is the same mix at a brisker tempo. I must say, I like this.
