Grids using MFB Tanzbär as sound module

I’m looking to get a Grids and have it use the sounds from my MFB Tanzbär. Unfortunately the Tanzbär only has midi-in, no cv/gate/trigger inputs. I’m searching for a way to convert the Grids’ trigger outs to midi in a way that is compatible with the bear. Triggering from a midi keyboard works (channel 3) - tried that. I was thinking of something like an Alesis TriggerIO (~120€m not Eurorack, 10 inputs) or a Doepfer A-192-2 (~130€, Eurorack, only 2 inputs).

It sounds feasible though pretty expensive, so I want to make sure it’ll work before I start investing… Is this the way to go, or is there a better way?
