There are 2 ways to achieve external stereo sidechaining in VST plugins:
- Use VST3 format.
- Use 4 inputs (1, 2 for signal and 3, 4 for sidechain) and DAW that supports 4 inputs routing (Reaper for example).
My choise for Molot 0.3 is #2. If you select external sidechaining in GUI it looks something like this:
But if your DAW doesn’t support 4 inputs, this is the version of Molot 0.3 with 2 inputs and disabled external sidechaining support:
[Molot 0.3: 2 channels version (VST, Windows 32-bit, 64-bit)]

Fabulous looking gear and it works beutifully
Big praise to you peopple pure quality innit
Excellent Vst
Vladg you are a genius, keep doing what you are doing……One day, perhaps you can make a complete channel with preamp, comp, de-ess, eq, limiter etc in your original fantastic style. I am sure you will knock everyone out of the water. Keep up the great work my friend.
