Little Fugue in D-major

Here is a little fugue I composed 24 years ago and played on antiquated MIDI hardware, it was - as far I could remember - a Yamaha TG-33 ...
Now I have adapted it a bit and played it back on the sample set of the Giubasco organ located in Bellinzona.
3 voices, manual 1, manual 2 and pedal.
As it was intended first to play on the piano, some keys had to be transposed .... the score is attached and I left it in origin for the piano.
