Are you sequencing within PTLE - physically drawing in notes with the pencil tool? If so, you may have to boost the volume of the midi note. In the edit window, just to the left of the channel, you can choose "volume" (or maybe it's labeled "velocity" I can't remember - anyway it's the one that defaults to "waveform" in an audio track, and "notes" in a midi track.) and raise the levels of the midi notes so that they transmit to the 01W at full volume.
