Re: [Faudiostream-users] faust2juce: slider scale not working ?

[Simon Hill]

Hi Stéphane
The issue seems to come from a conversion that is performed when setting the 
slider’s value (lines 525, 567, 574)
The functions are fConverter->faust2ui() & fConverter->ui2faust()
Removing these functions and passing the unchanged value solves the problem, at 
least partially.
The values are no longer incoherent, but the scaling is not the same. For a 
frequency slider with a range of 10Hz-22kHz, the middle value is ~470Hz in 
FaustIDE and 1421Hz in JUCE plugin

Similar problems were reported: can you possibly debug what happens  ?
