Hi

There's no such a function BASS_ChannelSetAttributes, remove the "s" at the end of function name

I know, I'm using BASS_FX version 2.3.0.3

Hi

I would suggest upgrading to the most latest BASS and BASS_FX.
Back then, the reverse direction couldn't be changed using the BASS_ChannelSetAttributes function.
Please use:
     BASS_FX_ReverseSetDirection
     BASS_FX_ReverseGetDirection

[dman10001]

I do not see those function in the doc.

how would I use them?
