If your STi-R has the "TSR" option under "bands" in the preferences menu then you have the latest firmware that is available for it.
I was under the wrong impression regarding the STi-R firmware having TSR.
The STi-R will not show "TSR" in "bands" regardless of which firmware is installed. TSR is not available for the STi-R.
Due to the recent popularity of the STi-R and the requests for firmware identification for them, I thought that this would be a good indicator of what firmware is on the unit, but it is not...
TSR has no effect on the audio ramp-up. I was under the impression that the latest software available for the STi-R (which would include the ramp-up fix) also included TSR support.
