Music Magic Accordions USA   


Roland FR-4x V-Accordion


With its light and compact design, responsive pressure-sensing bellows, and full-range onboard speakers, the FR-4x feels as familiar as your favorite acoustic accordion. But with the same powerful sound engine as Roland’s flagship FR-8x, this digital accordion goes even further. Choose from a wide selection of accordion sounds from around the world, and play in silence using headphones or connect to a PA for live performance. Control other electronic musical instruments via the MIDI connector, or record your playing to a connected USB stick and share your music with the world. While its sounds and playing feel are reassuringly traditional, the Roland FR-4x is an accordion for the modern age.

Let Music Magic USA show you why we are BY FAR your best choice for all your V-Accordion sales, service and support needs.

At MMUSA - America's Original V-Accordion Dealer - we are not best because we are first, we are first because we are the best!


Music Magic USA has for the past 20 years prided itself for being #1 in Accordion Innovation and the premier V-Accordion dealer since day 1. As such, it is only traditional and expected for us to have held the first public event introducing FR-4x in 2016 and to follow-up with the first area introduction of the FR-4x in 2017.

If you have been waiting patiently for the most capable, manageable and intelligently designed V-Accordion, then wait no more!   The 37 Treble key / 120 bass FR-4x from MMUSA offers:

  1. Many top of the line features of the FR-8x flagship (The same FR-8x sound engine! Similar sound-by-sound editing customization capabilities.)
  2. Much lighter weight – 19.6 lbs (7 lbs lighter than an FR-8x / within 1 lb of an FR-3x)
  3. 198 on-board Orchestral sounds / almost 1000 Accordion registers from around the world / 32 Organs
  4. The Guaranteed best FR-4x V-Accordion Package to be found anywhere from Washington to Massachusetts and everywhere in-between!  (Financing is also available to qualified buyers.)
  5.  Available free FedEx shipment or maybe TAKE HOME A NEW FR-4x from the event (unless we sell out before then).  We will, of course, have the Roland FR-4x at the event in Red and/or Black)
  6. Your Satisfaction is Always Guaranteed or your money-back!
  7. Receive additional bonuses: special custom configured bonus .ST4 Sets and .UPB User Programs, Roland compatible USB Memory Stick with file and memory backups, free lessons and supplementary help bulletins only from MMUSA - to make sure you get the most from your new FR-4x.  Our technical support and product training is much better and more interactive than that provided by any other dealer.  Sit behind your new accordion, not in front of your DVD player, and learn to enjoy your custom configured FR-4x.
