I've no idea on DX, but with VST you've not much other choice than to implement 4 discrete inputs for stereo sidechaining, just like everybody else. And even then it's up to the host wether it'll support it or not. It's a bitch, innit?rpmartino wrote:DX and VST have less straightforward sidechain support but we'll still look into getting it working in these formats, it will just take longer.
For mono you need to make a separate version as well. *sigh*
luckily VST SDK and host support is improving slowly when it comes to this.
