In reference to Gordon Kurtenbach's problem with syncing his drum
machine to his multitrack, I'd like to make the following comments
and suggestions.
I also had similar experiences using a Yamaha RX-15 with a Teac
80-8, and as somebody else mentioned, this type of crosstalk problem
is not unusual. It's just that in most cases it isn't critical (and
often unnoticed) because you're dealing with analog signals that
will get mixed together anyway. The problem occurs when analog
signals are recorded adjacent to the data (sync) signals.
One way to get around this that does not require any extra hard-
ware, is to record the sync pulses on the first pass, but nothing
else. Then on the second pass record the drums onto any track(s)
except those adjacent to the sync track (remember the crosstalk?),
using the sync track to provide the external clock. Next, use the
recorded drum track(s) as your reference for those instruments that
will be recorded next to your sync track. When all the tracks are
filled you can go back, polish up the drum patterns if necessary,
and rerecord the drums again using the sync track as your external
clock. You can add effects to the drums at this time if you know
what you want, and this will allow you to use the same effect device
later with a different setting on a different instrument.
As a word of caution, you might want to be aware of the fact that
syncing your drum machine to this external clock automatically dis-
ables your MIDI clock capabilities. This will probably be of no
consequence until you try syncing up with a synthesizer or other
MIDI compatible equipment, at which time your only option will be to
start over using a different sync method (i.e. Korg KMS-30). Time to
go out and buy some sort of interface device!

[STEVE McGOWAN] I'm a new user of MIDI equipment, and my experience is limited but growing (aside to Peter Barada: I did buy the Mirage and TR707---Thanks for your help!). But it seems that you could lay down a sync track with something like a TR707, use the sync track to later drive the TR707 through other material (to be recorded later) and/or have the TR707's MIDI out serve as the clock for a sequencer or other device. I can't verify this, because I haven't used tape sync yet, but from the literature it seems doable. So far all I've done is control a sequence on the Mirage through the MIDI out clock of the TR707. By the way, I've run into some problems with this that someone might be able to help with. I have a sequence that consists of some bizarre rhythms (four measures of 11/8, four of 12/8, one of 15/8). The problem occurs on looping through. The drum machine has individual measures clicking in and repeating the sequence, but the Mirage doesn't restart its internal sequence until the last measure has gone through SIXTEEN beats (i.e., the second beat of the next measure), looping thereafter with a start on that second beat. Any ideas what I might be doing wrong? (Another peripheral question: I haven't figured out how to cause drum tracks to "loop" on the TR707. Is there a way?) Thanks in advance. -- "There!
