I have tested both Ableton Live with the SP-16 and Renoise with the SP-16 over USB MIDI. Both of these DAWs send the correct Song Position Pointers as I jump around the song, but the SP-16 seems to ignore the messages. When I instead set the SP-16 as master it does send a Song Position Pointer message, but only once (when the song starts) and it is always position 0, regardless of where in the arrangement I start playback from. As I jump around in the arrangement, no further SPP messages are sent.
It certainly seems like the Song Position Pointer implementation on the SP-16 is broken. This feature was introduced in firmware 1.2 and has its own settings in the settings menu, but it does not work.
It is quite difficult to integrate the SP-16 in a DAW setup when it does not follow the Song Position.
Is this a known bug? Is there a road map for fixing it?
