Karma or Program Crescendo Diminuendo for accordion

[vstkeys]

Hi there
Just wondering if there is a way of programing a crescendo and diminuendo on sound ( not sequencing ) . The sound I am trying to perfect is an accordion sample. I want to emulate the bellows when the accordion is sustaining a chord/note, the real instrument produces a subtle crescendo and diminuendo with the gentle opening and closing.
I figured out how to make the attack softer using the filer but the volume only goes up in steps, not very smooth. Just wondering if there is a way using karma or if as anyone thought of that trick yet

I would personally use an expression pedal or perhaps a breath controller if you have one.

If you want it to happen on every note, then I would just program the amplitude envelope to do it. The filter/attack is not really where you want to go.

Otherwise, if you want more control over it, an expression pedal or breath controller as was suggested is the way to go.

This guys does a good job emulating an accordion with a breath controller (starts at 1:52 in the video)...

Many thanks for all the help guys!!
I looked at the breath controle but as I sing and play that would've been imposible. I also had a look at a breath controller usb that works with a pedal, just got me wondering if that would work on the kronos.

Oh Also another question, maybe I should open anothet thread but ......is it possible to have the filter alternating accoringlly to velocity so that the sound can get from normal (bypass) to mellow/dark?


I tried a few different filter settings but only makes my accordion sound weird like a synthsizer

That's probably because an accordion doesn't really do that. Or only very slightly. Keep the resonance low and the range very small.
