Weird script problem in 3rd party Kontakt library

I am currently struggling with a 3rd party Kontakt library that behaves oddly (in Logic):

When I load the nki and immediately strike a note, it kills my audio output with a loud pop and subsequent silence (then I do the usual thing like changing any audio buffer value etc in Logic to make it work again).

I can, however, avoid that when moving the modwheel slightly before striking the first note. The modwheel does blend between different dynamic layers in this instrument, so it may be a wrong/missing default value for choosing the pp layer?

The developer (really a nice, kind and helpful guy) tells me he doesn´t know how to fix it either since that issue is apparently only happening for a fraction of his users, and that I best just move the modwheel before striking a note.

The workaround works but is unsatisfying to the nerd in me (plus, I occasionally forget that after loading a project file... and POP) - however, script-wise I am just a humble beginner and don´t know how to start debugging other peoples´ 30.000+ lines scripts... (it isn´t locked).

It´s so annoying though that I wish I at least knew where to look - just in case one of you fine people has a tip for me (except "just move the modwheel, man!" ) where to start looking?

Thanks!

 

What's the library? Also, what happens if your project starts with some MIDI CC #1 value already set, before you play any notes?

 

Fluffy´s Dominus Choir. When I start with a cc1>0, then all is fine. However, inspired by that question, I just set the modwheel to 1, then saved the instrument like that, and reloaded it. Now it shows me a different dynamic layer on startup visually, and it worked fine for one reload actually. But after restarting Logic and then loading Dominus again... pop-and-silent again...

 

I have got the same problem. The third party plugin I am using is Fluffy Audio Dominus Choir Pro. Everything I try to play a track I hear a loud pop - followed by no sound - except for the loud pop to keep repeating. Can anyone help.

 

Same Problem for me!

 

The script issue appears to be an uninitialized value CC[95] was causing an evaluation of log(0) which is undefined.

A quick (incomplete) fix would be to add the following line after the "on init" line:

set_controller(95,127)

This initializes CC[95] to 127 so that it doesn't trigger the bug upon loading the instrument and pressing a key.

However, there are other parts of the script where this issue can manifest. To address those, add these two lines below the line you previously added:

declare $fixme
make_persistent($fixme)

Next, perform a find & replace, substituting ALL BUT THE FIRST INSTANCE of %CC[95] with $fixme

Finally, there are two locations where you need to add the following block of code:

if (%CC[1]<40)
$fixme := 40+((127-40)*(%CC[1]-0)/(40-0))
else
$fixme := 127
end if

The first location is the line below:
while (%noteEvents[$EVENT_NOTE]=$EVENT_ID and ($EVENT_RELEASED=$FALSE) and ($prerollLoopCounter<$prerollTime))

The second location is the line below:
if ($loopCounter<$CROSSFADE_TIME)
