The PlugSE is designed to serve as a bridge between the host and the synth and in principle the OB-6 should be connected directly to the PlugSE via MIDI. By default, most of the VST hosts are set to grab all MIDI ports on startup and this may create a connection problem for PlugSE users.

If you are using a Windows PC many MIDI interfaces including OB-6 USB MIDI are not multi-client - this means that ports can be opened and used only by one application at a time. It also means that in practice, after you start the host application the host may first access and open MIDI ports that your synth is connected to and prevent the PlugSE from accessing the same ports later on.

Here is what you should do:

- Start Ableton.

- Go to Ableton preferences/devices and disable both OB-6 USB MIDI IN and USB MIDI OUT.

- Run PlugSE.

- Go to PlugSE MIDI Setup and select  OB-6 USB in and out. At this point you should have it ON-LINE.

- In Ableton, select the MIDI track and configure OB-6 PlugSE for track's output.

USING OB-6 PLUGSE IN ABLETON

- Configure OB-6 PlugSE for track's input if you using OB-6 as input.

To establish proper MIDI communication between OB-6 and the PlugSE/Editor:

Please make sure that the Global Parameters are set MANUALLY (not through the computer) on Prophet 6 as follows:

MIDI Channel: ALL

Param Xmit: NRPN (nr)

Param Rcv: NRPN (nr)

MIDI Control: On

MIDI Sysex: USB (Usb) or MIDI (Nid) - depending on your connection

MIDI Out: USB (Usb) or MIDI (Nid) - depending on your connection

Also, please make sure that the MIDI track channel has the same MIDI channel as the OB-6 MIDI Channel or the OB-6 MIDI channel is set to ALL.
