Hi Norman,
I have checked out your observation on both my Genos and Tyros4 and you are quite correct.
In spite of how it might appear, the Pitch Bend range of the Left voice is
not set by the 'Range' button on the Genos 'Assignable' display or the Tyros4 'Controller' display. Instead it must be set on the Genos 'Keyboard/Joystick' or the Tyros4 'Mixing Console - Tune' displays.
The default setting for this seems to be 0 which means that if the range is still set at the default value and you assign Pitch Bend to a pedal and include the Left Voice, unless you change the Range on the Genos 'Keyboard/Joystick' (Tyros4 'Mixing Console - Tune') display, the pedal won't produce any pitch bend on the Left voice!
If you set the pitch bend range on the Genos 'Assignable' display (or Tyros4 'Controller' display), this changes the range for all Right voice parts but not the Left part, on the Genos 'Keyboard/Joystick' (or the Tyros4 'Mixing Console - Tune') display, but on the 'Assignable' display you can set different ranges for each Right voice part, and as long as you don't subsequently change the single value on this display, this produces different bends for each part when the pedal is used. However the 'Range' button on the 'Assignable' display obviously can't show the correct setting for each part (since there is only one button). What is displayed there seems to be anyone's guess, but whatever it shows, it is virtually useless in such a situation.
In terms of Glide, this only works for the Left voice if its Pitch Bend range on the above display is set to a value other than 0. The range of the Glide is then set to the same as the Pitch Bend range, rather than what the pedal setting display indicates! At least the 'Up/Down' and 'On Speed'/'Off Speed' on the latter display are correct for all Left and Right parts.
So, well spotted Norman, since it means that contrary to how it appears, Pitch Bend and Glide can be assigned to a pedal for the Left voice part, in spite of Yamaha's best attempts to confuse us!
I assume that this situation has existed for many years on many models of Tyros & PSRs, so maybe Yamaha think that all is perfectly OK and there is no need to bother mentioning anything about it in the manuals!
I''ll let anyone who needs to use this function check out what happens if you store such settings in a registration!
Regards
Ian
