I have a similar issue.
I have a 2 channel sequence (talking skulls driven off a servo). Testing in Vixen with my Lynx dongle works nifty as it's channels 1 and 2. When I then want to take this to my FPP device I try to convert into either a xlights sequence or a Pi sequence, both times I crash.
I can convert the file fine if I leave the number of channels I created alone in the profile file from 0-15, but what I really want to do is use a higher universe where the servo will be in the field and so I thought I could be clever and change my output number to a higher number. See my profile file I created below.
Also attached is how far xlights gets in the conversion for me.
thoughts?
