This may not be new to gurus but it sure was for me because when I searched for info on it I found nothing. I use Rosegarden for the little midi editing that I do, then use the playback to save a sound file with jack_capture. Most midi soundfonds don't provide enough depth for my liking nor the micro vibes that give soul to a sustained note; my solution for the former is to play back the the segment with 2 different instruments such as a ZynAddSubFx-155 clean guitar and a GeneralMidi-34 picked bass. This combined with the arpeggiating notation (below) gives me the depth and timber ..although the sustain remains dead-fishish, and for someone else to fix

Try the staff in the diagram with different tempo (I use 80) and also test different balancing of the two sounds to get what you want.
Enjoy!
