Jerry,
It might be that the EV5 has the wrong resistance. The Yamahahaha FS7s I
have don't seem to step when set on volume. Now on some other settings
there's a lot of stepping, but that's due to the hyplodipuladed squantum
mechanic synth engine and its personal interpretation of Planck's Constant.

Hi Jerry,

The Yamaha volume pedal standard is completely opposite of most of the rest of the world:

Ernie Ball/Roland/Old Korg Standard --

Tip = potentiometer (pot) wiper
Ring = voltage reference
Sleeve = ground

Yamaha/New Korg Standard --

Tip = voltage reference
Ring = pot wiper
Sleeve = ground

In case you're not familiar with the names, a standard 1/4" guitar cable has only the "tip" and "sleeve" connections; a stereo cable adds the "ring" connection between the tip and sleeve.

This could be part of your problem. If you need to use a Roland pedal with a Yamaha synth, or vice versa, you have to swap the "tip" and "ring" connections on the stereo 1/4" plug, or the pedal response may be quite erratic. This can be done by cutting the plug off and soldering on a new one, or by making a short adapter cable (1/4" stereo jack to 1/4" stereo plug) that crosses the wiring inside the adapter.

Regards,

-BW

Wow. Cool Info. Thanks Ed and Bruce. I feel much better about my blue
beauty. I think I'll just pony up for the Yammie pedal.

Hi Jerry,

FWIW, the Yamaha FC-7 is one of the best volume pedals ever made. Korg uses it (with Korg logo, of course) on their BX-3 and CX-3 organs, and I've converted several for Roland users because they like them better than the Roland equivalents. I have one FC-7 that I bought in 1986 that is still going strong.
