Hi! I just tried to hack the small beginnings of basic jack_transport support in a midi-sequencer. All it should be capable of is jack_transport_start and stop. I just opened a client (jack_client_open(package,JackNullOption,&status), where status of of jack_status_t. and called jack_transport_locate(client,0) and jack_transport_start(client), before starting the midi-playback and when finished called jack_transport_close(client); Only it won't even locate me to 0, it somehow fails there. Is there anything special I have to consider? any special jack_function, subscribing me elsewhere, opening a seperate thread? Please, does anyone have any ideas on this?
