Music producers and performing musicians in search of the classic hybrid sound of the JX-8P will be thrilled with the Roland Boutique JX-08 Synthesizer Module, a recreation of the iconic JX-8P that was embraced by top session players for it’s warm pads, shimmery chorus, and crystalline textures.

The JX-08 module features all the unique sounds of this highly sought-after classic, in stunning detail, and includes 32 original patches. Additionally, powerful new additions are included such as a polyphonic sequencer, 111 new presets, an onboard arpeggiator, and 17 new effects including the JUNO-106 chorus, SDD-320 reverb, lo-fi compressor, super filter, pitch shifter, and more. The JX-08 sequencer features two parts, each with 64 steps and 8 notes per part with motion recording, a random patch generator, and memory for 128 patterns. A clock input syncs the onboard sequencer of the JX-08, which can result in unexpected phrases, rhythmic variations, and other happy accidents.
