I recently received an OWL3 upgrade board for my Lich so I thought I’d give a go running my Spectral Harp patch on there but discovered it was having buffer underrun issues and could run with the full 4096 spectrum that Genius uses. This seems strange because as far as I am aware the chip on the OWL3 board is the same as the one in Genius? I created a very simple test patch to eliminate all possible causes of the discrepancy:
What I’m seeing is that Lich runs at ~50% CPU when performing a 2048 IFFT and Genius runs at ~12%. What could be going on here?
