I own maybe a thousand :/ music apps and this is top 10

There are a lot of unfair reviews on this app from people that don’t understand its basic functions. It send midi riffs to other apps and it does that exceedingly well. Basically, it will create sequences of music that you can have a hand in the direction the sounds take shape. Most generative apps like this sound robotic and uninspired, but after weeks with this one know it’s a front page of the iPad app. Cheers devs, curious to see where you take this.

Buggy and not made for iPhone

Really wanted to like this app -so disappointed. First, there has been no attempt at all to make this usable with an iPhone screen size. The font size is nearly microscopic on my 8 plus. However, I was willing to live with this once I learned by trial and error where things were and accepted that it would take multiple taps to actually hit my tiny targets. Once I was able to use the app I got many great results and song ideas. Saved them and when reloaded found the patterns were replaced by a single repeating note. Came back a day later and found all my saves were totally gone. Completely useless.

Really Diggin’ It

I just purchased Riffer earlier today and I’m really getting some good stuff out of it. Auv3 is great for using multiple instances. If you are looking for some generated monophonic midi I highly recommend this app, I really like generating something then editing it to make it my own. Some of the reviews originally scared me away but after a couple updates I finally decided to purchase, and I’m so glad I did. Great app!
