Vortex Sound Research

I'm trying to do this exact setup here https://youtu.be/-7ZQwf6PWjM

But I'm only getting response from the first midi channel of the volcano sample. I tried changing the parameters in the beatstep pro editor but I'm not yielding any results. Do I have to update the rk002 cable in anyway? I also made sure that the correct global settings in the volcano sample were accurate.

Any help would be appreciated!
