Chopin Prelude No 4

Below is a render of Chopin Prelude No 4 by Sonic Field.

It was done using much the same patch as that for Requiem For Peace; however, in this case the left hand notes were more gentle and this lead of the contamination of the attack with a slight high frequency click sound. To round this out I added from Bessel filtering just in the attach of the left hand notes (patch for this after the video). I used a Bessel filter to make sure there were not significant phase issues remixing the filtered and non filtered signals.

[ this patch removes clicks from the 
  attack phase of notes when soft-attack is true
]
