iPeng on iPhone, aynchronised players - control

Hi

Can somebody help me understand synchronised player on iPeng please?

I have several SB3 players in the house, and I have two synchronised players (kitchen and lounge). Anything I play on one, plays on the other. This has all worked really well for the last 15 or so years. No issues there. But I've typically used remote controls, and those are now starting to fail.

The two players show "synchronised" on iPeng, as expected. However there seems to be no way to control the power or the volume independently when they are synchronised.

Here's my problem. My remote controls do sometimes work, and other people in the house might turn the volume up or down on an individual player, or they might power one off. I then come to play music and a player is off, but I have no way to switch it on, that i can see? I press the power control button on iPeng and the other player goes off. Press it again and both then come on as expected.

What am I missing please? Using iPeng, how can I control the power and volume, on an individual player in a synchronised player set? My players are synchronised solely for playing music.

Many thanks


Jim
