Absolutely. Set your MIDI keyboard to the same MIDI channel as the MiniBrute and you're in business. Connect a MIDI cable from the MIDI out of the controller keyboard to the MIDI in of the MiniBrute. If you're not sure which channel the MiniBrute is on you can use the MiniBrute Brute Control software to check, or if you can't do that for some reason, once the two are connected via the MIDI cable, set the controller to MIDI channel 1 and play a note. If the MiniBrute doesn't respond change the controller's channel to 2 and play a note. Keep doing that until the MiniBrute responds and take note of which channel the MiniBrute is on (so you don't forget).
