I recently acquired a new JX-305 Groovesynth and am working my way through the Quick Start and Owner’s Manual. I have been very impressed so far, but have not yet been able to make the modulation lever work. Pitch bend works great, but no mod. My biggest tip off to a possible problem was when I tried the Turntable function (see Quick Start page 39 or Owner’s Manual pagge 47). I am following the directions exactly, but can’t get it to work. I reset the entire device to the factory pre-sets and tried again without success. How to you get it to work or do I just have a defective box? Thanks in advance.
