Here's a morsel from Vierne's wonderful collection of miniatures.
This was recorded on the demo sample set, which is limited to a maximum of 5 stops at any one time without audio interruption.
This work showcases a range of unison flues on GR and SW with the Pedal Soubasse 16, plus and minus the SW Hautbois and Trompette. At the end there's a quick taste of swell strings plus Violon 16 and Soubasse 32 on pedal. The wide, smooth dynamic range of the swell box is evident.
The recording mixdown contains equal proportions of front and rear samples.
