ОК, Richie. i'll try to explain 1. Copy factory rhythm to user rhythm. To do this, select the factory rhythm (source), press Pattern Editor, then (F+)menu, then Store, Select empty User Rhythm (target) slot. Press Enter (if slot isn't empty - will be prompt to repalce it) You have read only user style 2. Make needed part to be editable select pattern (e.g. Normal) by rhythm controller buttons, select part - Bass by < > buttons. Press Function+Pattern sequencer. In menu, select Part Edit -> Copy, Select Rhythm from source factory rhythm, and pattern and part needed to edit. (Sure?Yes) 3. Edit part conversion table (as well as other parameters) Return to menu (1 exit) and select PartPara. Change Table to 04. Press Exit until Store. Change slot to target user rhythm (as in p.1) Press Enter Replace?Yes Conversion table is changed to bass f-root I hope it will help
