Hi Folks , I've been following the Bk7-M subject with great interest .
I downloaded the manual and read that the Fc7 footpedal can be used to control many of the operations , but the slow /fast rotary effect does not seemed to be controlled by the FC7 footpedal board ?

If this is true, is there a work round to overcome this situation .
For example how would you go about setting the BK7-m up to play "whiter shade of Pale "...if you could not activate the slow /fast rotary .
Someone told be to use the after touch effect but unfortunately neither of my midi accordions have aftertouch ,although one of the midi accordions does have touch sensitivity .

Best Regards ........Giovanni

Hi Giovanni,

I play this song on the BK-7m already. Try using one of the 2 patches which have a rotary switch built-in to the initial touch of the sound. Dyno Rotary and Rotary organ both have this, so if you hit above a certain velocity your get fast rotary, and below that velocity you get slow rotary. It is very useable. Rotary Organ first appeared on the EM2000/G1000 keyboards, so it's been a round for over 10 years and is a great patch.

Alternatively you will have to send some system exclusive from your midi controller, if it can.

To change up from slow rotary to fast rotary, using MFX 88 Vibrato-OD-Rotary send this message:
F0 41 10 00 00 4A 12 18 00 02 31 08 00 00 01 2C F7

To change down from fast rotary to slow rotary, using MFX 88 Vibrato-OD-Rotary send this message:
F0 41 10 00 00 4A 12 18 00 02 31 08 00 00 00 2D F7

I think that will work. The A-Pro series can send system exclusive information, but I am not sure which other controllers can.

On other Roland arrangers, the joystick controls the slow/fast on-off function.

Hi Guys,

I experimented with the pitch bend controller but that has no effect. the issue is that there is no CC number assigned for the rotary speed change. I have also tried the sysex strings I copied in above and they don't work, so forget that one.

Hi John and Don ,thanks for taking the time and trouble to reply to my question it is most appreciated .
I was just thinking, could it be done by setting up 2 performance list /registrations one with a slow rotary organ and the other with a fast rotary (both would include the style acomps set up for "whiter Shade of pale " and get it to operate uy using the FC7 footpedal by operating the "next /prev " performance foot switches and just alternate between the 2 functions as and when throughout the song .

regards ....Giovanni

Hi Giovanni

The standard cc code of the modulation wheel is 1, and pretty much every controller has this set as standard.

Virtually all VSTi, hardware synths etc. use the modulation wheel on organ sounds to change the rotor speed between fast and slow, (Forward fast, back slow) so it would be unusual if Roland changed this.

Check the Midi settings on your controller to make sure it is sending out modulation wheel information, and that the Roland is set to receive modulation wheel cc code information, hopefully this will then allow you full control of rotor speed.

Hope this helps

Bill

Giovanni, yes your idea will work well.
