Yes it worked at least under GR 3.9
Did you get any error message?

Christophe,
thank you for the two suggestions. The second one (using selectors) is preferable for me.Unfortunately the grc flowgraph you provided does not work for me at all: it does not produce any samples at the output.I had to remove the first selector for it to work (see attached).
I don't know if this is another bug, but can you confirm that the grc flowgraph you sent me (with two selectors) worked for you?

I would have implement this differently:
- First solution combine To filters taps in one filter such as
- final_taps=rrc_taps*(pulse-1)+rect*pulse
- with pulse =0 or 1 (obtainde with a QT GUI Chooser)
- BUT filters must have the same number of coefficients
- 2nd: use QT Gui selector as in this flowgraph. (it can be extended to multiple filters easily)
Regards, Christophe
P.S. my flowgraph is for GR 3.8 /3.9

Hi all,
I have a flowgraph with QT chooser choosing between rect pulse and rrc pulse.I also have a QT range where I want to control the rolloff factor of the rrc pulse when chosen.However, in the flowgrpah it seems that once the rrc is chosen I cannot change its roloff factor dynamically from the QT range.
I have tried it in both 3.7 and 3.8 and I get the same result.Is this a bug?Is there a more appropriate way of achieving this result?
