If an effect is what you're after, you can just use an effect.

I'll start from scratch - adapt to your own Performance.

1) Recall "Init Normal (AWM2)"
2) Touch Part 1, choose "Edit"
3) Select menus "Effect" -> "Routing"
4) Touch to right of "ON" and just under - "Type" box for "A" or "B". Likely your Performance will already have effects here. I'm going to change "A" (Insertion Effect A).
5) Select category "Trem/Rtr >" then "Auto Pan" then press [ENTER]

There's other settings you can tune - but by default the effect will set up as the "E.Piano" preset which is what you've asked for.

If you want to dig into more settings, press the "Ins A" or "Ins B" sub-menu depending on if you changed the A or B effect. I changed "A" so I'd press the "Ins A" sub-menu to edit more details. All sorts of things to play with in the settings.

The Parameter Guide (in the downloads section of yamaha.com's support page for your keyboard) details the effects and what the various parameters are for with more detail.

[quotePost id=117485]I'd like to know how to get that effect when you hear an EP panning back and forth between left and right channel.

Do you prefer when it's per note (one note plays on the left, next on the right) or if held notes move from left to right and back again at a rate that's fast enough to be noticeable during held notes?

Effects aren't the only option - you can modulate Pan with the Part LFO. It's probably "easier" or more authentic to use the effect - but LFO is an option too.

Holy cow! Quick responses. You guys are awesome!

What Jason explained is what I'm looking for. A pan effect, when you play a note and the sound pans back and forth automatically.

I guess my title was misleading and wrong. I originally thought you had to have two parts, not performances, to do this. Didn't know it was already built-in. Pretty cool.

Now to try it out.

Thank you all again!

Your description of what you were after was precise. No problem. As a novice learning the ropes you are doing great. Stick with it.

You could setup the "Variation" effect (touch the Performance name at the top, choose "Effect" and go through the same general instructions but change "Variation" to the desired effect instead).

This is allows for multiple Parts to participate in the effect if you want. It's not usual for such an effect to be applied this way - but it's available.

Autopan is a doozy!!

Try wearing headphones, because it can also pan front to back (like surround sound), so it sounds like you have a Synth flying around your head.

There's a lot of neat effects in the MODX that can save you the bother of building them "into the synth engine"... although it is useful to know both ways.

Also, from what I read of the OP - this isn't called for, but there was an inference that effects are peanut butter spread across all elements. This can be true - but it's not the only option.

Every element has the option of connecting to InsA or InsB or Thru. So assuming you have the most common order of:

Insertion Effect A --> Insertion Effect B --> Master

Then routing an element to InsA will have the element participate in both Insertion Effects.
Routing an element to InsB will have the element skip Insertion Effect A and only use Insertion Effect B.
Routing an element to Thru will have the element skip both Insertion Effects.

I was filling the hole in your previous description regarding the options.
