(In advance, sorry if my answer is a bit long .... in fact I'll do it in several installments and to read from top to bottom , because there are not enough characters allowed lol)
I take a moment to respond to your message and your request for an opinion on your piece to which I reply with great pleasure.
I always appreciate to discover that on Audiotool we are a certain number to attempt to house music or differently than trance oriented (I really appreciate anyway, besides the best Audiotool user’s here have a huge talent in this field music there, and I am appreciative of their work).
If I can share my humblest experience of what I did, so here it is. Feel free to use the "mute" and "solo" on the mixer control(Centroid). It allows the detection if two sounds, at once or more, are synchronous or asynchronous (that is to say in phase discrepancy = their rhythm are out of sync).
For the rest and at this point I will not go into detail about the use of other tools (but I can give you any other information later if you wish) I hear at times (but maybe I wrong and my ear is old lol) just this phenomenon on your track.
At the same time, and it may seem more complicated at first, it is necessary that your "loop" or note played belong to the same range of sound, the same key somehow. Of course there are exceptions that sound pretty good. However, when you play several sounds that are not all on the same line, then it can disturb your listener's ear and give the impression that your song sounds weird.
That is to say, we know there is something wrong but can not figure out what. What I say may sound very technical, but in fact if you own or just causes your ear to the musical listening 2 see maximum 3 tracks simultaneously, then you will make the corrections yourself without having to handle the musical notation.
In all cases there is a French proverb that says "this is by forging that one becomes a blacksmith," and in English "practice makes perfect".Then I sincerely invite you to continue in this direction that is yours, and continues to compose songs that inspire you as you already do. The music comes from the heart friend ... the music comes from the heart ...
