years of frustrations past by . many synths but a nightmare to get them all play nicely in sync together. No mac or Pc , no daw or any decend settings could fix the problem of sync. Then i read about this device and saw some videos about it. First of all its not cheap but worth every penny of it. It uses an audio output of your soundcard to send a pulse wave to the multiclock , there audio is always prioritized by computers its a more stable an reliable method to sync synthesizers.
on top you can add swing , program some cc controllers and stop start the sequencer of your synths. It has only four outs but with some midi thru you can really fix your sync issues.
my advice buy it today !!! thank me later
