I’m an FR-4x owner. I used to be jealous of the FR-8x’s display. Then I downloaded the free editor for the FR-4x. Oh, the things you can do … ! By the way, the editor for the FR-4x came out before the editor for the FR-8x. Roland wasn’t even thinking about making an editor for the FR-8x, but then a bunch of FR-8x owners got jealous …
I bought a used BK-7m to use with my FR-4x. Then I discovered that it doesn’t have Klezmer styles, and I’m a fan of Klezmer, and Yiddish Theater, and Yiddish folk songs. But a while back, I had purchased Sherry Mayrent’s Klezmorim In A Kestl, a collection of klezmer styles for Band In A Box software, and I created some backing tracks for my FR-4x. They work well, and the sounds are pretty good. The downside is that those tracks are very tune-specific. Unlike the BK-7m, the tracks won’t follow chord changes from the accordion unless I record tracks that only have drums, and even then, I can’t vary a lot of elements while using them.
People criticize the FR-4x because it has a 37- key treble keyboard as opposed to the 41-key treble keyboard that goes with 120-bass accordions. The lack of those four keys is something I can find ways around when playing tunes. If I need the physical keys for practicing scales and other exercises there’s always my acoustic.
Some people also wonder why the FR-4x doesn’t have a lithium battery and on-board charger like the FR-8x, but uses ten rechargeable AA cells that are recharged externally.
My guess is that a lithium battery and on-board charger would defeat the low-weight character of the instrument. At this stage, with limited mobility and anticipating a hip replacement in August, I’m not about to take my FR-4x out of the house, so I’m running it on the AC adaptor and not even using batteries.
