Then it seems like there’s noise when the patch becomes more complex since you also mentioned the following after you thought that the power boost was damage.
Maybe changing the block size to 48 or higher could help. I have encountered a noise issue when making a granular patch and changing the block size to something higher helped. I may have been pushing the CPU.
I highly recommend making the patch simpler and then building up again step by step until there’s noise.
The power boost may not be damaged.
Also feel free to share the audio file of the noise in the thread too. You should be able to share the file that can be previewed here without us needing to download.
