yes, fair point that Soundcloud's yukky 128kbps does the sound no favouts! The final timbre on the WAV just reminds me of a loudspeaker dying though lol
I agree, it would be useful to have some sonic examples with the filter more closed, so we can hear more improvement in envelope snappiness without getting distracted by raspy sizzles.
