I absolutely like be this program! I have been using it for the past 4 years and it’s amazing that with a free account you can make 15 songs! Don’t get me wrong, I have had to delete a few to make space, but I think that’s a good amount! I would buy the full version online but I don’t have money of my own XD. I totally recommend this program! It’s so easy to use and has most everything you would need to write music! The only flaws I have ever seen are just the audio. Usually use pano for everything so it’s not a big issue for me, but some of the instruments sound very unreal. Recently. Have been making percussion pieces and the instruments don’t have the same feel. What I think would be awesome is if there was a way to put in your own sounds from garage band or something and Ben upload your own recorded sounds! Other than the sound quality, this has been the only program I have ever used! As a matter of fact, even though the sounds could be improved, they are at least better than every other pr gram for have used!

Good for pop songs, not for symphonies

Let me preface this by saying that this is my favorite music software. It is easy to use and if you know your way around, it will give you what you want.
That said, if you write a piece that is too big(more than about 3 minutes or two instruments), you start experiencing problems.
Let’s talk about my 200 measure Acapella medley. For starters, it takes an average of three tries and 90 seconds to get all of my instruments on screen. It regularly refuses to scroll and leaps back to the beginning of the piece for no reason whatsoever. Playback is consistently scratchy past measure 180 and it is getting hard to put in new notes because the app apparently does not want to click where I want it to click. Copying and pasting is also becoming an issue, as it sometimes refuses to highlight and sometimes inserts measures smack in the middle of the phrase I was trying to paste.
Long story short, this is a great website and I recommend this to anyone writing music. But emphasis on WEBSITE. The online website only has one of the aforementioned problems (jumping to the beginning).
Please make this app more phone-friendly. Hugs and kisses.

About the newest update...

I really think it was unnecessary to make it so you have to subscribe to change the playback volume for the instruments, when that feature is free to use on the website version. You probably did that because you realized people could cheat the system and gain access to the reverb option without subscribing, am I right? I'll confess I am one of those people who took advantage of this workaround, and while I see some reasoning in the change made in the newest update, I still feel like there was a better way to go about it.

Other than that I love this app; there aren't many MIDI programs like this that give you as many options for free as Flat does. However, while I will continue to use this app, I do genuinely feel you should bring back the option to change the playback volume.

Thanks for your feedback, that's great to hear! It's true that unlike our webapp, the audio mixer is included in our premium subscription right now. That's a choice we made to keep the interface simple in term of explaining what features are premium and the ones available for free.
