I can't find how to properly format the optional part of this message...
trigger_session_record (optional: record_length)
trigger_session_record works, but how to set the length?
I've tried various things like:
trigger_session_record_record_length $ > ('Song' object has no attribute rigger_session_record_record_length $)
trigger_session_record record_length $ > (invalid argument, of course because it misses the "_" )
trigger_session_record_length $ > ('Song' object has no attribute rigger_session_record_length $)
I don't understand why it tells me that Song doesn't have this attribute, otherwise I guess it would responds the same way with just "trigger_session_record", no?
