G2 expected polyphony?

[half-diminished]

Can you please help me to determine whether I am getting the polyphony that I should for OS 1.62 Exp?

I am worried because there was a piece of plastic rattling around in the case when I got it (I have attached a picture), and I have read posts on here where forum members said that some of the their DSPs stopped working. By the way, does anybody know what this piece of plastic is supposed to do?

I know that the polyphony of the G2 is a maximum of 32 voices (depending upon patch complexity), but this is all I am getting on these voices from
Patchbank 4 of Factory Bank v.124 revA, with the expansion chip.

When I activate each voice in a single slot by itself, I get:
Piano1 DX 22 (24) 22 voices of 24 requested
Stringpad 1 DX 22 (24)
Rhodes1 DX 22 (24)
Wurli1 DX 22 (24)

I can’t get full polyphony on any of them. Yes, I am aware that they are complex patches, but why would they be written with 24 voice polyphony if I could not get all 24 voices from a single slot setup on the Expanded G2?

When I layer slots 1 and 3, I get:
Piano 11 (24)
Rhodes 10 (24)

When I layer 1, 2, and 3, I get
Piano 7 (24)
Stringpad 6 (24)
Rhodes 6 (24)

And when I layer all four, I get
Piano 5 (24)
Stringpad 5 (24)
Rhodes 4 (24)
Wurli 4 (24)
I get a total of only 18 voices.

Whether you have the unexpanded G2 or the expanded, would you mind loading up these patches, and seeing what you get in terms of polyphony, just for comparison?

As another example, If I load these voices into single slots all alone, I get:
Welcome G2 15 (32) PatchBank 1
Piano 1 22 (24)
AccGuit 15 (17) PatchBank 1
YetAnotherOrgan 14 (20) PatchBank 1

If I layer all four slots, I get:
Welcome G2 3 (32) PatchBank 1
Piano 1 3 (24)
AccGuit 3 (17) PatchBank 1
YetAnotherOrgan 3 (20) PatchBank 1
This is a meagre total of only 12 voices! Is this normal?

Another disturbing thing that happened last night (although I failed to replicate it today) was that when I layered four slots, the sound would cut out after about 30 seconds of playing, until I cancelled all the slots except for one. I can’t remember exactly which combination of four patches did this, but I am pretty sure the last set of four that I shared with you.

What do you think? Is my G2 damaged? Should I return it through Reverb.com and wait for another?

Thank you,

Regarding polyphony, your numbers looks correct.

The loose plastic piece looks like a standoff, a plastic spacer that holds a circuit board in place. If should be repaired r replaced. Whether you want to do this yourself or return to the seller is up to you; but the polyphony numbers you are getting are quite normal.
