Seems like Songtrix got laughed at and passed over BUT This is a great sketch pad!!! Sorta like a Garage Band but all midi and no samples. Ive messed with chord pulse in the past and this is so much better. Also better than fractal music back in the day on the C64 LOL If you are a musician that could use some ideas and inspiration give this thing a shot. Play with any chord progressions and melody's to a changeable rhythm. The chord thing is really cool in this.. no joke. I wish daw's had this built in. Export those sketches via midi to a daw and have at it. It's really useful to create a backing track in a short period of time to further expand your ideas. I find myself going back and forth between reaper and this with killer results. Its actually a really useful tool. Just passing this on.. if you play guitar, piano, bass.. etc etc check this out. PS: I'm not sure its that great of a tool for EDM or rap.. I would say no
