Hello,
Thanks for your interest in Misha! Yes, you should be able to send MIDI from Misha to the Beatstep and have the MIDI from the Beatstep control your Arturia Collection plug-ins. There are also many possibilities for Misha with your other modular/eurorack devices. Misha works great as a sequencer/controller for all of your MIDI or voltage controlled gear.
Let me know if there are any other questions I can help you with.
