SYNCHRONIZATION 299
You can use this type of synchronization if your system combination shows no timing
changes.
MIDI time code (MTC)
If you require a reliable integration of the MIDI tracks of an internal sequencer into
Samplitude's audio tracks, use of the MTC format is recommended.
MIDI time code or “MTC” includes so-called time information in addition to the MIDI Clock
signals, although only start synchronization occurs in Samplitude. It is therefore important
that both systems have a word clock or are connected to any other type of digital audio
clock. This helps to successfully avoid drifting.
Chase lock sync
If tempo fluctuations occur, Samplitude can make corrections in slave mode that ensure
time-precise synchronization. This function is called "Chase lock" and can be activated in
the synchronization dialog. This option should always be used, if an element involved in the
synchronization cannot be clocked centrally via Blackburst, Worldclock or a digital input
and Samplitude is the slave. This is the case, for instance, if the timecode is on one track of
a multi-tape device. If you systems are linked via a digital audio clock, you should not use
chase lock. However, please note that the recording is resampled in real-time according to
the timecode fluctuations if chase lock is activated. This results in a higher CPU load and
possibly undesired changes to the audio material if it is played later with a different
timecode reference.
Samplitude supports real "Chase lock" synchronization, i.e. audio playback can be
controlled by an incoming timecode signal (MC or MTC). Not only the starting point of the
audio playback is controlled externally, so is the playback speed as well. Samplitude is
therefore capable of following analog tape devices or VCRs that always have some slip for
longer periods.
MIDI machine control (MMC)
This is a signal for controlling external controllers that support the MMC format. Samplitude
can also be remotely controlled via MMC commands from an external controller or mixer.
APP (ASIO positioning protocol)
As part of the ASIO driver architecture, an SMPTE or MTC equivalent timecode can also be
transmitted via the digital connection (SPDIF, ADAT) or special interfaces of the sound card
(LTC, video burst), so that no additional MIDI connection is required for this type of
synchronization. Samplitude thereby precisely follows the input signal of an external source.
The ASIO driver of the audio device has to support this feature.
