A few years ago I went to a guy to build for me a kickdrum/percussion maker patch in max msp, and payed a few times the price of Kick2, it wasn't successful.
The attached picture is the concept I sent him.
It has 2 Tabs:
A drawable frequency over time like Kick 2
And drawable waveform.
It means you will be able to design endless percussion sounds, sound effects, I would even use it to design explosions for films or robots sounds etc.. it opens many possibilities..
You made an amazing plugin!!!
I think that with this, and other feature requests it will be even more comprehensive sound design feature rich tool!
