Hi Scott

Thanks for that. This particular harmoniser has loads of preset harmony types, amongst which are some "Vocoder" types. These respond by reproducing exactly those notes which the machine is fed with, rather than producing a generic 5 part harmony (or whatever) based on a recognised chord being received, which would be the case for the "Non-Vocoder" presets.

I think I might need you to elaborate a little, as I'm not quite sure how this would help. The fundamental problem I'm trying to solve is caused by this particular player's use of single finger chording, rather than a lack of communication between the two devices.

As an example, to play a C minor chord using single finger, the Tyros expects a C and the next lower Bb to be played. The harmoniser, not unreasonably, translates this as meaning C7 if fed from midi channel 4 (the LH keys). In "vocoder" mode, it would just provide two harmony voices - the C and the Bb - again implying a C7.

If I were to use a "Vocoder" setting, which Tyros part (i.e. midi channel) would you suggest might be good to drive it with?

Again - thanks in advance for any advice. Mike
