Trumpet Tune in D (for organ & trumpet)

Festive prelude for organ and trumpet in C.
The score has been written with Harmony-Assistant, a French, cheap, but very powerful notation software. The organ is Menesterol moist. The trumpet part is played first by the upper manual of the organ but this voice is muted when I record the audio with Hauptwerk. So I get a wav file containing only the organ part. Then, from Hatmony-Assistant I export the upper voice (the trumpet) as a MidiFile.The very good software Studio-One-2 of Presonus is used here to produce the trumpet sound from this midifile, add reverb and merge it with the Hauptwerk wav file.
