AL-1 'pop' with all OSC set to 0

[Gunnar]

Hi,

I'm a fairly recent Kronos owner, got my K2/73 in December and I'm slowly getting the hang of things. Enjoying it immensely though :) And this forum is a great resource :)

While playing with the AL-1, I've stumbled upon an oddity which I was hoping somebody might shed some insight on.

The issue occurs as follows:
- Starting from "Init EXi Program", selecting AL-1 (Which should be a plain Saw on two oscilators)
- Go to "Control Surface -> Tone Adjust"
- Assign Slider 1 to OSC 1 Level
- Assign Slider 2 to OSC 2 Level.
- Slide the two sliders so OSC 1 and OSC 2 levels become 0.
- Hit any key on the keybed and listen for the faint, but still quite audible, 'pop'

In the EXi -> OSC/Pitch -> Mixer section, all oscillators are now set to 0 and there are no modulation sources assigned, so by my understanding there should be no sound generated.

If I were to unassign and then reassign the levels, the pop goes away.

some synths produce a click deliberately when setting the Attack to 0. If the attack of an init AL-1 program is zero, then this could be intended behavior. I never checked it, but it doesn't sound like strange behavior to me.

The default attack is indeed 0 for the AMP EG. Note that this only happens if the levels have been set to 0 from the assigned sliders in the Tone Adjust control surface. If the OSC 1/2 levels have been set to 0 in the OSC/Pitch->mixer with an empty tone adjust there will only be silence.

Gunnar, It's a bug in my code. Looks easy to fix, though.

Thanks for the update, Andy!

(and to Qui for answering my post initially :)
