midi to audio

MIDI TO AUDIO: OK

I did several recordings with ableton live 8.1.1 using an external midi source (Roland hdp-15 as well as Casio CDP-200R), routed this into a midi track, put some midi efects on it as well as a midi instrument and then faded it to an audio track and everything worked fine.

MIDI TO AUDIO: not OK

The last days I used again as external midi source the CDP-15, faded it into a midi track with the arpeggiator and chord effets and then with the external midi instrument MS wavetables. This was routed to an audio track.
Playing this (and recording it) I could hear the effect, but the audio track did not record any audio signal. When I exported the whole live set as a wav-file the midi output was missing in this wav-file too.

Does anyone has an idea what is going wrong here?

Best regards
