Playlist Riders gain steps are too rough (3dB!), steps should be half a dB!
Are you talking about the metering in the top half?? I’m pretty sure the actual gain riding mechanic would be in much smaller increments just as it is for Vocal & Bass Rider.
Mine (Soundgrid Version) is pretty coarse, totally not comparable to Vocal & Bass rider, try yours and let me know your expiriences.
