Without wishing to teach you to suck eggs:
Firstly, make sure the MIDI IN on the Voyager is connected to the MIDI OUT on you sound card, and vice-versa for the other MIDI ports.
Secondly, your Voyager should have RX and TX channels, which, I assume, will be located in the MIDI SET UP menu. These have a range from 1 to 16. Set these up however you wish, but let’s suppose you use channel 1 for both. This means that your synth will transmit (TX) and receive (RX) MIDI data on channel 1.
Thirdly, the Voyager should also have a MIDI LOCAL control (this refers to the actual keyboard) which can be ON or OFF. When using a sequencer, this should be set to OFF, as not doing so will give you a flutter echo, as the data will be looped back to the synth, via the sequencer, a split second after you physically play.
Finally, in your sequencing package, chose channel 1 for recording. You can see the simple relationship here - all the channel numbers must be the same, if you sequencer and keyboard(s) are to comunicate with each other. Hit record and play the Voyager; you should begin recording and, depending on how your sequencer works, see the MIDI data appearing as you play. When you are done, stop the sequencer and play back. You should hear what you just played.
Hope this works?
The above only skims the surface of what is possible using MIDI, but as long as you set your channels up correctly, your devices should get along fine. I believe you also own a Pro 1? If you ever get a more advanced MIDI interface, with multiple INs and OUTs, and want to sequence this along with your Voyager, make sure you use different channels ; if you don’t, both machines will play the same seqences.
I myself will be receiving my Maple AE very soon (not that I’m bragging, honest) and will need to do a similar set up, so if you have any problems, email me - I will soon be able to help.
All the best.
The Unknown.
