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?

My favorite app just got better

The 3.0 update has taken Riffer to a whole new level. The density function adds so many more rhythmic possibilities. Having 4 Riffer instances in one with tuning, velocity, duration, and density capable of being randomized independently or all together gives me an amazing amount of control over just how random everything gets. I already use this app on nearly every single thing I create. I cannot recommend Riffer enough!

Loving the update so far.

Still lots to explore but this update is a game changer for Riffer, it is far better than it used to be.

I have found a bug however which is pretty annoying, when the note grid is limited to two notes ( c2 and c#2 in my case), randomizing riffer causes a bug and crashes the plugin, it won’t die but it stops working and reacting to UI changes. It also raises the DSP on both apematrix and AUM from 0 to 99%.
