The Reason veterans all remember how the Propellerheads always stated, that Reason won't never get VST support. But in the April 28, 2017 it all changed as in the this day they announced Reason 9.5 point update, that added a VST support. This update was free for all the Reason 9 owners.
Reason 9.5 and later supports plugins in the VST2 (2.4). The VSTs have to be 64-bit.
VST3 plugins were not supported before, but that changed in the 19.12.2022, when Reason Studios released Reason 12.5. VSTs that output MIDI are not yet supported in Reason.
So yeah, never say never - the Props added audio in back in the days, even they claimed they'll never do so and the same happened for the VST-support as well. It's all good though, because now people have a freedom to use their favorite VSTs inside of Reason, just like all the other DAWs as well.. After all the VST-format is the biggest and the oldest plugin format, that is the industry number one in the plugin world.
By the way, Reason 10.3. was an update that optimized the Reason's performance. This made Reason to be able to handle shitloads of more VSTs, than before. Cool!
My benchmark test proved that Reason can now handle 200% or even more devices in the Reason. Yay!
Anyway, here's a Video about the VSTs in Reason:
