Please keep up with your platform-it is a wonderful tool and has propelled our son into writing his own music in a way that no other platform or app has been able to.

I would like to testify that the Flat community is truly something special. Not only have we been supported musically, but we've made countless friends that support us in our personal struggles; seeing us through the best and worst of times. We've never seen anything like it. The community, all bonded from a common interest and passion for music, is beautiful. Thank you, from the bottom of our heart to everyone who has supported us and showed us kindness in our journey making music.
