I posted this before here but I’m doing it once again adding more details.Please read & reply.

Well my setup is a Motif ES6 with an mlan interface & I use a PC with XP on it.I use the Mlan to record into cubase & somehow I’ve set it up to dump tracks from my ES onto Cubase,Nuendo.I’m not too sure how it works but it works fine.Recently I installed Reason4 just to use some of its loops.With some difficulty I set it up to communicate with Mlan.I am now able to transfer midi data into Reason & trigger the tones in Reason using my ES.Now here is the problem: When I play on the motif to send midi data or trigger the sound on reason,the sound I hear is a phased & slightly distorted sound.Now after I play & record on Reason & then play it directly from Reason without the sound is crystal clear with no phasing.I even tried selecting the PC’s built in sound card & I still get the phasing sound while playing through my ES.When I play directly on Reason using just my mouse on the virtual keyboard/drum machine it does not phase.The midi data that goes from my keyboard also seems fine.I know there must be a simple solution to this.Maybe the sound while going or coming is getting 2 signals at the same time that is causing it to phase.Please let me know how to go about.Thanks & have a blessed new year.

Sounds like slight latency. Adjust the buffer size.

You probably sorted this out but its not latency; since you use Reason in ReWire mode you have to disable Reason's own midi input. Otherwise it will input midi from a) the rewire source and b) reason's own midi input at the same time. That's why everything "phases" (just like when a Reason newbie copies the ReDrum pattern to track and doesn't disable its own sequencer).
