LTC->MTC is not yet supported by A3, because A3's MTC generator still needs some work for proper vari-speed support [2]. However, there's jltc2mtc from https://github.com/x42/ltc-tools analog LTC audio (e.g. from tape) - -> soundcard - -> JACK audio-port - -> jltc2mtc - -> jack midi-port - -> ... https://github.com/x42/mtc-tools features a standalone MTC generator (gets sync from jack-transport). HTH, don't hesitate to ask if you have any questions, robin PS. All tools properly compensate for latency. But in order to achieve exact sample-sync, the port latencies of the physical jack-ports must be set correctly (using jackd's -I -O options). The actual roundtrip latency depends on many factors. The only way to learn the value is to measure it. To do so, there's jack_delay [3] by Fons Adriaensen; a variant of it (jack_iodelay) comes with jackd itself. [1] http://gareus.org/wiki/a3extsync [2] LTC->MTC is already supported by A3 but accuracy does not match our expectations so it has been explicitly disabled.
