Silver Echoes

I ‘m trying to use various iPad music apps (Beathawk, Sampletank, etc) in ‘midi learn’ mode to assign my CT-X5000 pitchbend wheel to various midi functions in the apps. No avail...it seems the Casio wheel cannot be used for any function other than pitchbend?

I am wanting to toggle the ‘Modulation Assignable’ button to activate the ‘Leslie rotary speaker effect’ that would GRADUALLY spin it up to ‘full speed rotate’....then remain there until I press it again to make it gradually slow down to a full stop again. Or—start fast, then slow down, then speed up. Etc etc. In other words, ‘press the button to gradually increase rotation...then press it SECOND time to decrease rotation speed. I can only make the rotary effect OFF.....or ON (‘off’ seems to be the normal effect of most factory sounds except the ‘072 RtfFdOrg’). There seems to be no way to gradually increase/decrease rotation speed. It’s either fast—or off. ’Drive Rotary’ sets the button so the rotary effect is OFF when pressed. None of the following function settings have any effect: OD gain OD level Speed Brake FallAccel RiseAccel SlowRate FastRate Etc etc etc Help? What am I missing?
