Hello All

I am fed up with the interfacing issues which I face on my home studio connection for 4 weeks time(Near).
I would surely value your time and valuable response on time. Can you please help?
I am using YAMAHA MOTIF XS6 as a Keyboard Synthesizer and Cubase AI4 as a DAW software.
For an audio interface I have m-Audio Delta Audiophile 2496 as the Sound card installed in my system.
I have connected MOTIF via a standard USB cable to the Computer’s USB port.
I have connected digital out(Single RCA) which was given at the back of the MOTIF to my S/PDIF IN of 2496.
The analog Out of 2496 is sent to Speaker system as an input. This is the configuration.
I have opened a new EMPTY project window in the Cubase Application.
Track -1: - By right clicking it I am adding a MIDI track and starting to record. It records fine by keeping the input bus as “All MIDI” and output bus as “MOTIF XS6-1”. And I can able to hear the sound during a playback. Note here is I am using the MOTIF keyboard’s sound.
Track 2:- But when I right click and add “Instrument Track” no sound comes from the keyboard. For this the same input and output buses are used. To get hear the sound I am changing the settings in the control panel of the 2496 from SPDIF/IN to WAV OUT 1. After changing I can able to hear the sound and record. Playback is fine to be heard.
Obvious case while recording and playback should be the sound of the Track 1 should be heard and Track2 should be recorded at the same time. Here the problem is Track1(MIDI) is not heard and I can record and playback only the Track2(instrument Track). I could not sort it out.
How should be the connection.
Please give a step-by-step method.
I am wasting my time on this.

Thanks
Sam
