This is just a demonstration on how you simply don't need a $300 DAW to make good music. Nothing but a good melody, staying on key and on scale, a drum pattern, perhaps a few effects here and there, such as reverb and echo, and overall, a harmony of sound that are organized, all of which put together results in music that is, what I call, appealing.
However, as much as I pick LMMS as my go to DAW for all my music, I will sadly admit that it is an insanely buggy DAW, and it has absolutely no guarantee of support other than a bug tracker and a mailing list. Not to mention, its UI is a bit lacklustre, in that it doesn't provide any good visual feedback to the producer on how their tweaks are affecting the sound, other than perhaps a live waveform preview, a spectrum analyzer, and the FX mixers. All of which renders it just that much more difficult to achieve audio quality that are on par with what would be produced by other proprietary DAWs. So if you're an established musician, and you owe your success to your DAW, then by all means use it to your hearts content; I will humbly suggest that you ignore my earlier snarky remark of all other proprietary DAWs being overpriced. They're priced that way for a reason.
Personally, I will keep using LMMS, but I have to admit, I have been going back and forth into trying Ardour. But I haven't produced anything tangible, so I don't really see myself using it as my DAW of choice in any future tracks that I produce. LMMS will most likely be the DAW of choice in my next track.
As for the video itself, I'm not taking any credit for the music. I'm only going to take credit for me transcribing the track's main chord progression, putting it all together with a bassline and a drum pattern, along with the pluck being thrown in to an automation track. Other than the ones that I mentioned, I'm not taking any credit for the chord progressions themselves, the vocals, and the entire genre used in the track, for which I give credit to deadmau5 & Kaskade.
