In another recent thread that was looking for new demo video suggestions, several mentioned Earhoof. I know this has been around forever, and I've had it for a good while too. But, I only ever really used it's presets with a few parameter tweaks. Mess around for a little while, then put it away.
I thought it was so strange that it must be difficult to wrangle it's back-end. Not so! It's surprisingly straight forward and easy to get wrap your head around. I went through the manual completely (only took about an hour) and hadn't realized how much control you have over the sequences and layers. AND, that you can import in your own samples to use, as well as record a performance, and or your live sequence patterns. Awesome!
This is such an interesting and unique app that doesn't get mentioned often enough. Or, maybe it's just been around so long that many have forgotten it. In any case, I can't put it down now. Can't think of another app quite like it either.
I rewatched a demo video by the Pants of Death dude. I think his demo videos are my personal favorites out of all of them. You get to see him find his way through and he gets to the point. By the end of his videos I always know exactly what the app does, how I might use it, and I've got a good understanding for how to get started on my own. It was the Pants of Death video that originally sold me on the seemingly intimidating Dhalang MG video.
Here's his Earhoof video that pretty much covers most of the app including the backend custom stuff. Though, I don't recall if he goes through being able to record performance and/or recording of your layer sequences vs entering them manually.
