EDITING A TAKE FOR SYNCHRONISED PLAYBACK
When you make a recording that needs to be synchronised to other audio material (such
as sequenced programs, etc.), providing you make the recording referenced to the other
audio, there should be no need to worry about synchronisation and the S3000XL will
follow exactly. There may be instances, however, where some adjustments need to be
made and this can be done in the following ways.
1
If the
selection is
, you may adjust the DELAY parameter in
millisecond steps to achieve accurate playback start times.
2
If the
selection is
, you may shift the note or track within your
sequencer.
3
Whatever the
selection is, you may use the EDIT page to trim a take for
better playback start synchronisation.
4
If the take ‘wanders’ during playback, this will be because the external reference’s
clock is not stable. For example, if you record a take referenced to an external
sequencer playing programs in the S3000XL but, after recording has been done, the
take wanders out of sync after a few minutes, it is most likely that the sequencers
clock is not entirely accurate and so, eventually, the two will drift apart. In this case,
use the
parameter to adjust the takes playback speed by minute
amounts. Unfortunately, there are no guidelines on setting this up. You will have to
make an adjustment, see if it improves - if it does not, you will have to try again with a
new value. All being well, however, this is only likely to occur if you use a different
sequencer to that which was used during the record process.
NOTES ABOUT SYNCHRONISING TO EXTERNAL AUDIO
In most cases, there should be no problems in synchronising takes to external audio
material because the playback response time of the S3000XL is extremely fast and sync
accuracy is in the region of a few milliseconds. Also, the take editing and parameter
adjustments described above should overcome any discrepancies you may encounter.
You will note, however, especially when running takes alongside sequenced material that
if you change the tempo of the sequence, the takes will be completely out of sync, even if
the tempo change is very small. Of course, you can use the VARISPEED control to bring
them back in sync but then, of course, they will be out of tune with each other unless you
transpose or re-tune all the sequenced material. Be sure to only make recordings once
you have finally settled on the tempo of your sequencer.
Similar considerations must be borne in mind when syncing takes to other audio material
such as material off tape. If you use varispeed on the tape machine, you will have to set a
suitable varispeed setting on the S3000XL to accommodate this. Another consideration is
that tape transports are rarely 100% stable so if you are running a sequencer
synchronised to code on tape and also running takes from the S3000XL’s disk, you may
find that takes will wander slightly out of sync, especially if that are long recordings.
