Simply WOW!
If you play an electric guitar or a bass, Soundraw IO is damn cool.
First, you select one of all the available theme (Corporate, advertisement, etc), the genre (corporate rock for me, electro for others maybe), tempo (128 bpm), length (10 sec - 3 minutes) and CREATE MUSIC.
Second, The AI will make you all sort of genre (if you did not select any specific ones), and you go through each composition. If you like it, you have 2 extra options (1. edit it or 2. keep it) before you download it for use.
Edit it - you can edit each composition, bass - finger type, etc and its loudness, or remove the bass, or you can add drum fills. In short, you can customise it. For me, i always remove the synthesiser.
Removal of the Bass Guitar, why? This is because i can play it myself. How? Step 1 - download the entire song and run it through CHORD AI (android app) and CHORD AI will provide you with the Chord progressions. Now, you know what and when is the bass chords. Step 2 - Once this is completed, you can remove the Bass from the composition and download it once again. And 2 - KEEP it (saving it inside Soundraw.IO).
Play it and record your bass tune, playing by yourself. Of course, it is better than ducking or removing BASS with another brilliant app, MOISES.IA (iOS and Android).
And finally, add on the electric guitar riff and overdrives on a ROCK Composition.
NOW, you have the backing track (Drums, piano, others) and I can add in the BASS/Guitar for all my video projects. It is definitely better than hunting for specific Drum Beat (or drummer), piano (Pianist) and others. And a music Composer.
Soundraw.io is all of them, leaving me with my bass/guitar. Oh Ya! You can listen to their original version of Bass/guitar and augment from there too.
So, Soundraw IO you compose and I play. And it goes into my video, finally.
