Hello,I came up with an envelope to create a crossfade between pedal up and pedal down samples in my piano sfz while preserving natural reverb and sustain.
Tested on sfizz.
Suggestion and refinements welcome.
Code: Select all (#)
<global>
ampeg_attack=0.005 // tiny attack to preserve transients
ampeg_hold=0
ampeg_decay=55 // long decay -> restores body + room sustain
ampeg_sustain=95 // near-full sustain, matches LIP bloom
ampeg_release=0.85 // natural tail-off
ampeg_vel2decay=0.4 // subtle velocity shaping (not too drastic)
ampeg_vel2release=0.6
ampeg_curve=5 // softer curve = more natural sustain
cutoff=20000
fil_type=none
note_polyphony=256
group_polyphony=256
<control>
default_path=\samples
