Pre-purchase question: I want to be able to record the midi data of the accompaniment parts to my computer sequencer (Sonar) for further editing (I'll be using the unit to create basic backing tracks in my sequencer that I will then tweek as necessary). Pg 66 of the BK manual has options for setting the Transmit off or on for each Acc part and setting the Transmit channel for each Acc part. So I'm assuming that the BK7m will in fact transmit this data to my sequencer if I set this Transmit switch on. Is that correct? Will it transmit via the USB (I would assume so, but the Wizard setting for Computer/Sequencer says it disables the styles and sets the unit in multi mode, so I would have to use one of the other modes and and it's not clear if the USB midi operates in the other Wizard modes).
