Serious Flaws (revised)

The midi and transport functionalities are seriously flawed. Note tie and sustain do not function properly when used in conjunction with note probability. This could be a great app. I question the choice of making it AUv3 compatible before fixing these issues.

Response to Developer:

Thanks for the update. When Ableton link selected and Sync Start/Stop deselected, transport does not begin on step one.
Midi Import selections do not stay deselected. Impossible to deselect all choices for no midi input. Would be nice to have more real estate in the UI for that.

Just tested latest version. I see now that volumes of ghosted notes (greyed out) must be changed manually in order for them to be filtered from the output. Can that be implemented programatically?

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.

This app is by far the best and most feature rich generative midi sequencer that I've ever used, and I've bought FAR too many!

Instructions or a tutorial would be a welcome addition. But after playing around for a bit everything was very clear and functioned flawlessly.

A feature request would be to save the current generated sequence as a midi file. Other than that, I couldn't be happier!

Thanks for the feedback, we work on midi file export for the next update. As for instructions, videos and manual you may visit the official product page
