Multiple releases choice based on elapsed time between NOTE ON and NOTE OFF (like for GrandOrgue/Hauptwerk)

[josephernest]

Hello,

How could something like this be possible in SFZ format ?
This is necessary to reproduce church organ sounds (this behaviour is common in GrandOrgue/Hauptwerk samplers)

<region>
key=60
sample=60.wav

<region>
key=60
trigger=release
off_time=0 0.5          // this release sampled is played only if and only if  0 < time_at_note_off < 500 milliseconds
sample=60_r1.wav

<region>
key=60
trigger=release
off_time=0.5 99999   // this release sampled is played if and only if   time_at_note_off > 500 milliseconds
sample=60_r2.wav

Thank you in advance!

Have a look at https://sfzformat.com/extensions/midi_ccs there are special HDCCs that track the time since the key was started

1. time_ since last key on (in seconds): 151
2. time since last key off (in seconds): 152

I do have this in a real instrument, where I did tremolo picking on guitar by having the note play on both note-on and note-off, using trigger=release for the latter, but if holding the note longer, the extra sample is not triggered. Not sure if it would work "properly" on organ, as the CC is I think tracked globally for the whole instrument, so if you've been holding one note for a while but then hit a second note a fraction of a second before you release the first, the first migth well get the "short note" release sample. But for tremolo picking on guitar, that's not really an important thing, so this seems to work>
