:hmmm: :lol: The 4 tracks are physically next to each other along the length of the tape, you don't need sync between the tracks, unless you get a razor blade and slice the 4 tracks apart along the length of the tape, there is no way they are going out of sync with each other.

But I see what you mean, I think, you want to keep the external device that you are recording from, such as the MPC, in sync with what is bounced onto track 4, so you can record new stuff in sync onto tracks 1/2/3.

With the MG614, when you plug a cable into the tape sync in or out jacks, it puts it into Tape Sync mode. This records the incoming tape sync signal onto track 1, along with the audio signal, and plays it back the same. The audio signal on track 1 in tape sync mode is limited to below 9kHz, it records the sync signal onto the same track 1, but above 9kHz, centred at 23kHz. The manual suggests to use track 1 for bass type sounds for this reason.

Check the Tape Sync page in the manual, page 27...

yeah thats what i meant, recording hi hats on track 2 then when recording the snare on track 3 it is in time with the hi hats (which i done by recording smpte on track 4).. ive been playing around with it and i think i got the hang of it.

I have been using the manuals for the sp1200 and the mg614, just seems to take a while to get my head around it.. i was born in 92 so i pretty much missed out on hardware and tape so this is all new to me haha

thanks though, appreciate it!

If you use the tape sync in/out, you don't have to give up a whole track to sync, as you are with track 4 at the moment, you can share the sync signal with an under 9kHz audio signal on track 1.

thanks in advance,



Great thread! I just purchased one of these and it is currently being serviced at VST.

I own a service manual and don't mind making copies (xerox) if anyone is interested. Send a PM.

Great thread. Good to see a few others getting some use out of this beast.

I used one for years and have over a hundred tapes made with it. I sold it when times were hard and was looking for one for a while. When...

A few years ago I bought another one and have been keeping it in storage up till now.

It was used as a mixer somewhat, but the tape section was never used (which was what I was most concerned about, because if nothing else, the 4 tracks can be output into my DAW, bypassing the mixer totally). It even still has the cellophane stuck onto the tape section.

However, the mixer is a bit grubby. Nothing bad, just a bit of grime that the seller was too lazy to clean off himself. So, my first question is: What would you say is the best way to clean the mixer up? I know I can take the pots and sliders off and I shall do that, but would you say it is worth buying some compressed air to give a little blast inside? Also, what cleaning materials would you say would be best to get it clean again but without damaging it?

I have looked at the tape section and it is true, the tape does not seem to have been used at all. There is no oxide that I can see with my naked eye. So my second question is, baring this in mind: Is there actually any need to de-gauss or clean the heads at all? It would seem pretty obvious that this isn't needed, but I just want to double check. And also if you can give any advice on good headcleaning practice, along with whatever de-gaussers you use, that would be great!

I actually have a second machine for spare parts. It is battered and one channel on the mixer doesn't work at all. The tape has difficulty playing and the rewind is a bit hit and miss. But still the tapes I have tried play back fine. Those GX heads would seem to last longer than everything else. I know the preamps are exceptionally good for what it is, a 4-Track, at the end of the day, so I'm going to hold onto it just in case. It has the dual voltage switch on the back, but unfortunately, my good machine only comes with American voltage, so I have had to buy a step down transformer for it as well. I haven't even plugged it in yet, but can't wait.

I bought some TDK SA-90 tapes today that cost me nearly £60, so all in all this little set up as cost over £800 after paying taxes on the thing coming in from abroad.

As has been noted, you can stripe the first track with s.m.p.t.e. and fsk and even mtc iirc - it is in the manual so don't quote me on that. And using it's HPF you can lay down a bass track or something actually to the tape as well, leaving you with the other 3 tracks free and all 4 tracks of tape being used. So, it is entirely possible to sync this up to you DAW, though it might be fun to watch the Akai play catch up as you instantly jump from the start to the end of the track in Logic or whatever you use.

So my final question is: Can anyone give some kind of instructions to actually do this? So far, many have talked about it, but no one seems to actually have done it. It would seem to be doable, but probably people just think it is not worth the hassle, but I'm determined to get this going.

I have a choice of DAWs at my disposal. I am thinking Studio One would be my best bet or maybe even Reaper. I have Ableton Live too, but I don't hold out much hope of that getting going. If anyone uses this feature of the Akai, what DAW do you use?

I'm also looking forward, routing this through my soundcard which is a Focusrite. It has six outputs and that corresponds nicely to the six 1/4" inputs on the Akai. I could then route that back into my Focusrite via either the monitor or main outputs on the Akai. Obviously I need to experiment and be mindful of feedback loops, but it would be great to have the main six tracks of the Akai hooked up in real time via my DAW. Studio One has a 'Pipeline' feature which also sounds very interesting and is something worth checking out. It is for mainlining hardware back into the DAW and utiilising it just as if it were a normal VST. Something else to consider. So, my final question is: Do any of you actually hook this up in a fashion like this, with your main DAW?

I think the great way about hooking the Akai/DAW up like this is, you could use the inputs on the Akai to record your vocals and guitars and whatnot, utilising the two Aux sends for effects and the semi-parametric EQ for low rumble cuts and sweetening etc., and recording it directly into your DAW, without having to faff about with hooking things up via your soundcard. Much more intuitive, flexible and hands on. The preamps on my Focusrite are pretty decent, so it will be interesting to see what gets the best results.

Obviously, feeding back from the DAW into the Akai, you would only have six mono inputs, or rather six mono inputs plus one stereo Aux, but you could still have some real fun and be creative with that. And if you wanted to, you could even use it as some kind of 'summing mixer' with the 8 inputs, equalling 4 stereo busses from your computer DAW, which you could then, in my case for example, record into my Panasonic SV-3800.

Long post I know. I'll figure it all out I'm sure. Just thought some one might be interested. Not that much information on these units on the whole on the web.

Any advice you have would be greatly appreciated, if you think I've missed something obvious.

Thanks.

Wish I knew the answers, but I don't .

Where you based?



Thanks.

I'm not really looking for answers. I'm usually the one that provides them to other people, in my experience. Just thinking out loud. Sorry for such a long post. I either have zero time and tolerance for stuff, or, I go the other way. Apologies.

I'm West Country in the UK, but I spend some time in London still and also the lowlands of Europe.

Cool.

If your machine needs a service or just looking at contact Jazzcat through this forum or Facebook. He has a banner on this site at the moment, and is highly recommended for all gear related repairs, MPC's , samplers, synths, servicing, mods, upgrades...

Thanks Clint.

That is great to know.

That is exactly why I joined the forum.

I'd actually like to get the PSU from my not so good working machine put into my good machine, if that is possible. I can talk to him about that.

Nice one!

Cheers.

by any chance did anybody grab that service manual? I tried contacting dude but he hasn't responded yet and my 614 is acting up again.

I refuse to give up on this machine.

Hello everyone,

New to the forum and have been following this thread for the past month. Just recently I purchased an MG614 on ebay and have been using it here and there for four track sessions to tape and just last night as a standalone mixer. The results have been very good and I can see myself using this machine quite a bit. I believe I read somewhere that an owner of one of these machines modded taps on each of the channel's transformers in order to get a direct out from each channel (maybe this is one of you?). This seems like the next logical step for a mixer of this sort if I am using it as a standalone mixer. I have noticed that I cannot effectively use the inserts on each channel (which for some mixers work) to get the true direct out path (going through the EQ section). As of now I am only aware of using the mixer in a standalone way by taking the 6 channels and summing them to a stereo output. This is limiting and can be cool, but having the 6 separate outputs would change the game entirely.

I guess my question is: has anyone on this forum heard of this mod or know of anyone who has successfully engineered the mixer to operate this way?

Since I am new to this machine, maybe I am missing other potential signal path schemes to get more than a stereo track at the end of the day. Let me know!

Thanks!

aloew
