No, it is not possible. But it SHOULD have been.
@darenager yes, I expect it is easy to implement in Octachainer, at least. I’m using a library called “libsnd” to load/save the audio files. I believe it supports cue markers now. At least reading them, not sure about writing. If it doesn’t, it isn’t that hard to implement my own audiofile loading/saving functionality, but it is safer not to. To support as many audio file formats and meta data stuff as possible.
Loop points would be nice as well. I don’t think sndlib can write loop points, but it can read them, so I could at least set the loop points in the .OT file from the wav metadata.
Very busy at the moment, so not making any promises. But an update at least fixing some annoying bugs is long overdue. So hopefully I’ll get around to do this as well. In a couple of months from now.
