Sophisticated Bellows ResponseFaster response, higher sensitivity and precision, plus detection of bellows opening/closing with new bellows pressure-sensing circuitry. A bellows resistance regulator knob allows you to adjust the bellows’ inertia to your preference.Super Realistic Accordion SimulationsAll sounds the FR-3x produces were obtained by sampling popular traditional acoustic accordions. This V-Accordion allows you to switch from an Italian jazz accordion to German folk, French musette or Russian bajan sound – without changing your technique. Also, the Virtual Tone Wheel is available to play amazing organ sounds in almost the same way as an organ player, using the treble section. You can also add a rotary effect (slow/fast). The FR-3x also allows you to enjoy playing simple drum parts with your left hand (bass and chord sections).Stand-alone Electronic InstrumentThough the FR-3x is a fully electronic instrument, you do not need to connect it to an amplifier in order to produce sounds. Its onboard amplification system is perfect for small venues, restaurants, etc. The FR-3x can also be powered using 10 commercially available rechargeable Ni-MH batteries, so that you don’t need to connect it to a wall outlet.Save Your Settings to a USB Storage DeviceYou can save your settings by connecting an optional USB memory to the FR-3x’s USB port. The USB host also allows you to customize orchestra and accordion sounds and to save the user program data.Superb Performance FlexibilityThe FR-3x allows you to control external MIDI-compatible instruments. The Treble keyboard and chord/bass buttons are velocity-sensitive, whilst the bellows controller provides more articulation possibilities than any other MIDI keyboard, MIDI wind instrument, etc. that you may be familiar with.
