The Roland JD-Xa is the big brother of the JD-Xi, and offers larger keys, a larger housing and more controls. It's still quite portable, though, and ideal for travelling sound designers.
Roland's System-1 is an exceptionally compact virtual analogue synth, which packs a considerable amount of potential. It functions as a regular synth in System-1 mode, or as a controller for Roland's own plug-ins in plug-out mode.
Rediscover the workstation! Roland's FA-08 Music Workstation combines more than 2,000 sounds (SuperNATURAL, Integra-7), a sampler, 16 trigger pads, elaborate Sound Modify options and full DAW control.
This Aira bundle is the ultimate asset for EDM producers. It contains everything you need: the acid bass tones of the TB-3, the drums of the TR-8, the leads/chords of the System-1, and the voice-manipulation options of the VT-3.
