Hello,
I'm running into trouble trying to hook up two tascam 688's with a midiizer (the last machine is new to me).
Both 688 are fully services and I have the manual of all machines involved.
I link all machines as described in the midiizer manual.
The first thing I find is that the master688 won't send the tc-gen signal trough to the slave deck.
I checked all connections, even changed slave and master to rule out a defect in the 688's, but it won't work as the manual states.
No real problem there, since i just stripped both tapes seperately.
Then I ran the SET UP-mode so the midiizer coud learn the tape characteristics, after that, the "chase" mode shoud provide a locking of the two systems.
This, I coud never achieve.(i tried it 25 times)
First of all, let me tell you the dip-sitch settings, to see they are right (according to the manual they shoud be).
On the mdiizer I've set the servo frequency on 9.6kHz to match the 688's, this because the manual states most machines use this frequency, the 688's manual doesn't state anything about frequentie, I hope I got that right?
Of course it is set for a serial/serial set up.
The time base on the midiizer is 96 ppq, the 688 switches are set on 96000bps, does this match?
Both 688 are set to "external sychronisation" and "fixed tape speed", (other settings gave even worse result, but the 688's manual and the midiizer manual contradict on this issue, I followed the midiizer's manual)
I striped both tapes with 30 ndf, is this advisable for casette tape?
They just never "lock" after a "set up" run, the slave follows the master after 2 or 3 seconds, if I play forward or play back, the slave does this with start-sto-start-stop movements.
Than I noticed something weird:
while running the master seperately the time code display showed 24 instead of 30 frames?
the slave was reading 30.
If I change the master slave position of the two 688's, the same thing happens, everytime the master reads 24 the slave 30, so it must be the midiizer reading something wrong, but what?
Just to make shure, I did everything again from scratch, erased the tapes and striped them again with 30ndf, with the same result, they won't lock, master and slave show different timecode (wich I saw as the reason why they coud not lock).
The next morning, without changing a thing, suddenly both machines show a 30ndf timecode???? (as they shoud), but still they won't lock????(I hate machines that do their own thing:-(
What a I doing wrong, can anyone help me out?
are my settings ok?
many thanks for your time, effort and willingness!
