Re-synthesizing/wave-tabling a trill texture played on my soprano sax with HALion 6, applying LFO modulation to formant shift, tweaking things on the fly. It’s recommended to experiment with the Window Type depending on the source one is re-synthesizing, for this sound the Blackman setting produced the smoothest results, as the “air” included in the sax sample wasn’t so pronounced (resulting in high frequency partials which sounded rather synthetic).
