Two Channel Display for Raga Music

(I need some people to make a recording that I can use to illustrate this mode. HELP!)
   
        This display can be useful for e.g. a vocalist and violinist working to refine their intonation together.
       Set Options | Dual Channel Input. To make a stereo input work for almost all Windows soundcards, you need to send the microphone cables to a pre-amplifier and then connect to the Line-In jack on the sound card. The straight microphone input is one channel (monaural) only. Some sound cards use one jack that doubles for microphone and Line-In; you need to select the appropriate one through the Recording Control.

       The display adds a second trace in the upper graph, in a different color. And double magnified graphs appear below the splitter bar. The color in the cents labeling signifies which is which.

      
Options | Transpose 2nd Channel  is useful if the range of the two performers is different. For instance, against a low male singer, it may work best to transpose the violin Down 1 Octave (assuming it is on channel 2). Work out the adjustments of the highest and lowest notes in the Options | Pitch of SA & Range dialog so that both performers are included.

    You may use the Silence Pause Threshold in the Instrument Properties dialog to help filter out crossover from the other channel. Raise it until whatever sounds bled into the other microphone aren't tuned. In this case, use View | Always Trace
to keep the trace moving smoothly if you want. [separate thresholds for each channel - in the future]

       An experiment in a different way of comparing the pitches is given in View | Multiview. When this is unchecked, instead of two lower graphs, both the graphs are drawn superimposed as one - with the second channel in gray. This would only be useful for practicing playing in unison. but the eye might find it useful to have the traces superimposed instead of having to compare two separate graphs.
