Note: The video is not live because of a lack of recording software that can record internal audio.
Note #2: While this was originally composed in Groove Machine, because of my lack of MIDI control to trigger the patterns on and off, the GMPRJ was translated into FL Studio, and then ran through the Soundgoodizer. (Maximus) Besides that. this is purely 100% Groove Machine, samples, synths, and effects.
I am a fan of the Groove Machine, but I believe you need to have MIDI control and internal audio recording to really make Groove Machine worth it. Even with all of that though, I would say FL Studio is a better investment, unless you are getting Groove Machine soley as a VST and not a makeshift DAW.
