Can I use FC7 expression padal with i500 keyboard ?

Hi,
I have bought new i500. It has only one port for pedal control. The manual mentions that I can use it only as sustain pedal with FC4 or FC5 pedals.
Is there any way I can use expression control (volume control) on i500 keyboard ?
If not inbuilt, can I connect any external devices to create expression control with FC7 like pedals ?
Please help.
Thanks,

hello shirish, welcome to the forum.
As far I know, there's no way to use expression pedal (to control the volume) on i500.

Thank you @Bogdan

It may not be possible directly, but is it possible to use any external devices that will help controlling the volume ?
I am not expert at this but just imagining !
If I connect my Lineout to a device which also has a port for FC7 like expression inputs (basically potentiometers) and then the device connects its output to the mixer. I can then connect FC7 and control the volume. Is this possible ? Are there any such devices ?
Thanks in advance.

I don't know if there's a device that would make that possible. And even if there would be such a device, then that would only be a replacement for volume knob on your keyboard. That is, by pressing the pedal, you would change volume of the whole keyboard -and that's no what we want. With expression pedal we only wish to influence volume of what we're playing with left and/or right hand (not the volume of the style).
What I'm saying is, such solution would only be usable if you don't use the accompaniments (for example, you're only playing organ voice without using styles).

This is not necessarily the case.  I learned how to play keyboard on a traditional home organ, and on those, at least on the models available at the time (late 1970's to early 1980's), the expression pedal controlled the volume of everything at once -- all keyboards, bass pedals, drums, and any backing automatic accompaniment, if one was in use.  To this day, one of my set-ups is a multi-keyboard system with bass pedals all going through a mixer, then to an amp and speakers.  And yes, I have a stereo expression pedal in line between the mixer and the amp that controls the volume of everything.  However, I normally only use the styles for the drums.

Without opening the keyboard and modifying the circuitry, there is no way to have an expression pedal control the volume of the I500's built-in speakers -- and the same is true of any of the current PSR-E keyboards, as well.  So, the only way that I know of to accomplish this is to essentially do what I did.  Use the phones jack as a line out, run the line through a stereo expression pedal, with the outputs of the expression pedal going to the inputs of a stereo amp and speakers.  Unless you're running other keyboards or audio equipment at the same time, you probably do not need a mixer.

You'll probably need to get an adapter plug that has a 1/4 inch stereo male plug that plugs into the I500's headphone jack and then splits that into two 1/4 inch mono jacks (left and right) to allow you to run the stereo signal through a stereo expression pedal, as the expression pedal will likely have separate left and right inputs and separate left and right outputs, all using 1/4 inch mono jacks.  And then, any adapters and audio cables you might need at that point depend on what kind of amp you're using and what kind of input jacks it has.

You definitely want to keep everything stereo.  If you just combine the left and right outputs of the I500 into a mono signal, you'll lose all sorts of imaging and fullness of the sound.
