I am using the Ver1 and Ver2 SSCs modified to Ver3. I am using the Mod 3 firmware. I am using the Smart String Utility that has the grouping feature. I think that is the latest one.
I have discovered that programming an SSC set for backwards and grouping of 1 works OK. However, with the direction set for backwards, the SSC will not function properly if the grouping is set for 11 or 12. That is the only numbers I have tried as I am trying to get my show running.
Essentially, grouping does not seem to work in the backwards direction.
