Independent shopping perspective
The Korena take
OB-X8 is an eight-voice analog synthesizer built around two discrete VCOs per voice and a choice of analog filters. Its 61-key, velocity- and aftertouch-sensitive keyboard works alongside pitch and modulation levers and an arpeggiator for hands-on performance control. A high-resolution OLED makes preset navigation and Page 2 parameters accessible, with over 600 user locations and more than 400 factory programs. OS v2.0 expands operation with binaural mode, oscillator waveshape selection, MPE, poly chain, and separate MIDI channels for bi-timbral use.
