Kudos and Feature Request

Fantastic and indispensable tool for controlling multiple synths in AUM from 1 or more controllers.

One thing that would make a huge difference would be to expose the AU parameter for the Panic button. Being able to map a button on a controller to initiate Panic would be must faster and more reliable in a live situation than opening the plugin and pressing the button in the UI.

Brilliant, A keyboard players dream 🏆

I can’t believe there are no new reviews for this amazing app, I have said all I need to say below, except for this- you really won’t know what you are missing until you try it for your self 👍
2 years ago.
I have been using this app for a while now and I just have to say that Layers is incredible, many of my projects use 3 or 4 different synth apps as lead instruments, the cross over from one synth app to another using just one keyboard and playing all parts in the same key area is seamless without any notes cutting off as you would normally get by just using Program Change using just one synth, no need for keyboard zones. You won’t realise how useful this app is until you have used it. 17th Oct. A MASSIVE thank you to Paul for his dedication in adding a new “ALL MUTES OFF” feature that I requested, Midi Layers just gets better and better ⭐️⭐️⭐️⭐️⭐️ 1st SEPT. As soon as I saw Paul’s YouTube demo of Midi Layers and what it is capable of, I purchased it without question. At first it took a little while to get into it in Cubasis3, but once I played around with it I soon realised what a fantastic useful app this is. Paul must have an amazing brain to produce an app of this calibre, he also has a knack of creating apps that we didn’t think we would need, but wow, we need them for sure, I wish this technology (and Paul’s apps) were available during the 90’s 👍 Thanks Paul

Doesn’t work fully in Cubasis

App does not work fully in Cubasis. Wasted money. It was designed for AUM. Only a few of the features are available in Cubasis. Developer needs to be more honest in his description.

Brilliant, just Brilliant.
