Yep. The modules you want are the Sequencer MIDI Source and Dest (from the Software IO section) and the Scope MIDI Source and Dest (from the Hardware IO section.)
The Sequencer MIDI Source/Dest forward MIDI data from (Source) and to (Dest) your sequencer. The Scope (or Pulsar/Elektra) MIDI Source/Dest forward data from/to the actual hardware MIDI plugs on your card. Here's a little picture with basic connections:
This setup will send MIDI data from the sequencer to the MIDI output plug on you card, and from the MIDI input plug to the sequencer.
You can use the MIDI activity and MIDI monitor modules (in the MIDI section) to monitor what's coming out of each sources for debugging purposes. There's also some MIDI merging devices if, for some reason, you need to send the output of more than one Sequencer Source to a single MIDI output port on you card. The merging devices are also pretty useful to send MIDI messages to a device from more than one source. For example, you could have your sequencer send notes to a synth, but control the knobs thru a control surface that goes directly to the synth from the outside without going thru the sequencer (hence much faster.)
There's also a MIDI filter that's pretty useful in some circumstances. For example, I have a Doepfer Pocket Dial plugged into a MIDI port. With the connections I showed up there, I get a weird problem where the MIDI clock stuff gets continually circulated. With a MIDI filter, I removed all System Messages (which includes MIDI clock) from the Doepfer, and fixes the problem! Yay.
