Hello Matt,

this is a fault of the 4013 flipflop (IC1) on the card. I had this fault many times here in my shop, and I think it is caused by age somehow. The LED of PRG 2 - 4 will light while you push and hold their buttons, but if you let the buttons go, only PRG 1 will stay, right?
You have to solder a 100k resistor between pin 3 and 7 and then it should work like a charm. Don't replace IC1.

Best

Michael

  Subject: [Simmons Drums] SDS V - Card won't change settings


    

  Hi Guys,

  I have an SDS V & recently both of my Tom cards are refusing to change from the factory settings.

  Is there a easy fix for this?

  Does anyone know what will have caused it?




  Cheers

  Matt
