Hi, thanks for the reply.
I've already loaded the Amber Soundpack, and it's working well.
I've watched pretty much all of Painless360's videos (including this one) - he's a very useful resource.
Unfortunately, this is only for the X9D with the F_Modes selected either by two switches, or with the 6 way stepped pot/switch plugged into position S3.
My X9E doesn't have S3, so I have put it on a spare pot channel (F3) and calibrated it.
The switch operates the Pixhawk F_Modes correctly via a custom curve, the problem I'm having is how do I assign the various PWM values (or percentages) selected via this curve to the Special Functions for each voice file?
I read somewhere (probably the RCGroups forum) that when you calibrate the pot/switch the radio assigns new input switches to each level - something like S31..S32..S33..S34 etc.
I'm sure I'm missing something stupid
