Roland JD-XA Anaolog/Digital Crossover Synthesizer
The JD-XA takes the crossover concept to an advanced level by seamlessly uniting cutting-edge DSP technology and pure analog synthesis.
The analog filter in the JD-XA has both a smooth sound and a lighting-sharp response, giving you a high level of creative control when shaping sounds. The accuracy and quick response of the JD-XA’s envelope is important too, as it defines the leading edge of the sound. Each individual analog part can have its own dedicated effect, and all parts can be processed together through digital effects such as master EQ, chorus, fuzz, and many others.
The crossover advantage provides musicians a wonderful marriage of detailed digital sound and powerful analog sound.
The digital section offers a diverse palette of sounds, from fat synth waveforms to crisp metallic timbres and beyond. Digital sounds can be routed through the analog filter, instantly adding organic richness. Massive hybrid sounds are also possible by using both engines together. For example, use Poly Stack mode to layer the four analog parts for richness and body, then add digital tones on top for extra spice.
Thanks to the powerful synth engines, effects, and hands-on controls, dramatic textures are easily created using common building blocks like synth waveforms and white noise.
Roland’s famous Supersaw waveform coming from a digital part becomes a very warm and rich pad sound just by passing it through the analog filter. Even simple white noise can be transformed into a range of complex sound effects that are perfect for film and game scores. First, enhance the noise using two TFX types, such as one for subsonic reinforcement and the other a short reverb for body. After that, process the sound through the analog Ring Mod and Cross Mod functions and tweak their controls in real time for a variety of cool tonal colors.
