A synchronization option has been added which consists of two modes: MIDI Click and Internal. To synchronize via MIDI Click the Filter's MIDI Input should be fed with the "High Note" (which is also called "Strong Beat" or "Bar Start"). There are two ways to do this: a) directly from host's MIDI Click output; b) from a MIDI track. (Note: sometimes there's one octave mismatch between host and a MIDI Device. For example, Cubase's C5 is equal to my keyboard's C4. (Strange but so it is)). This mode is more reliable but it occupies "Click" option and if you turn the click off the synchronization will be lost (that's why the MIDI track was mentioned as an alternative sync source). To synchronize via Internal mode the Time Signature should be set. For example, if you set it to 10/4 in a 5/4 song the retrigger will happen every two bars. The Filter begins to count from pressing Play button and as it gets clocks from the internal host's engine it needs some time to catch sync (one bar). In this mode you have to control whether the strikes occures exactly at the bar lines because sometimes they don't. (SynthEdit logos should light up at the bar lines).
