I discovered Blend during a mooc on Coursera, from berkeley music school, teacher was Erin barra. Here my link with my 3 first assignments from the course : https://blend.io/raseliche
I encourage any producer to engage into those free courses, not only you will eventually learn things, but it will give you the strength and the motivation to produce tracks for the assignments (with deadlines, peer reviews with other students an all, etc.), well this helpt me finding motivation and discovering Blend, a really good product.
Pros:Backup projects, cool community giving help and advices, a nice interface with even an app. Platform for musicians, to share with musicians
Cons:I only see pros using blend, never encountered any drawbacks
