In 2011, and for a couple years after, I was using a Roland BK7m module with lightweight controller keyboard and T.C. Helicon Harmony M voice processor.
Today in nearly 2019, after going through several Yamahas, Korgs, Ketrons I'm back to about the same thing. In fact I can't really tell any difference in recordings of the same song from then and now.
I said at the time I sold the BK7m that if Roland ever made a keyboard version of it, I would jump on it. That's pretty much what the EA7 is, with some additional enhancements. . . new styles, a few new sounds, and of course 61 keys. It also has a good vocal processor, but no harmony. And it has speakers, pads and sliders.
It has a sound and styles I like. Certainly doesn't have some of the bells and whistles as competing lines, but it also does some things they don't do.
Just thinking, I could have probably saved a lot of time and aggravation by not doing anything until now!
I remember getting away from the module because I needed so many add-ons that it was a chore to set up all the time. It played midi files but didn't display the lyrics, except through an external monitor. It even had the makeup function that is missing now!
So a laptop, vocal processor, monitor, controller, mixer all connecting cables and power supplies--it was a difficult configuration.
I think the EA7 may have a little better sound processor, but it still sounds pretty much the same to me. And I like it.
Just food for thought.
I may post two recordings of the same song and see if anyone can tell which is which.
