Definitely needs work.

Edit: improvements by developer is a good sign, works great as long as you do not touch parameters while in playback.

Shouldn’t have been put in the App Store yet with its current performance.

Sends random chord stabs any time you adjust a parameter.

It is monophonic (I will re-read the description to see if they mentioned that), not a total kill but it’s good to be aware of.

Would be nice if it had midi channel out select instead of just device select. iM1 from Korg for example is multitimbral.

Tying notes together instead of having a drag function is a little annoying.

The chord stabs are the biggest killer. If this gets improved it might be nicer.

The option to have midi input to quickly change root note is nice.

Thank you for the honest feedback, we are working on correcting these issues. We’re taking notes and we will make sure we implement each request as new version-updates roll.


Yes, please.

This dies exactly what it says it dies. A nice variety of note/scale/sequencing randomization and mutation. It absolutely supports Ableton Link and MIDI In/Out, so synchronization is a breeze. (Not sure what other reviewers are missing this option, it's in the configuration settings - cog wheel icon)

I used it to sequence a synth in AUM with zero issues. I'll be using this A LOT.

Thanks for your support! Enjoy!


Nice tool with a few teething issues

This App does exactly what it says it will do. It’s simple to generate new musical ideas and route them using MIDI to the destination program of your choice.

Sometimes when changing parameters what sounds like a chord will be played instead of the expected note. This is a bug that needs to be fixed.

Another useful addition (or maybe it does this already but I haven’t figured it out yet) would be if the App could generate a few sounds of its own - this would be useful for quick demoing.

Thanks for making this App!

Thanks for your feedback! We are working on correcting this bug ASAP. Riffer does not produce any sound but would be a nice addition for quick demoing.
