Latency when Rewired to Logic8

[EdRyan]

Anyone got any tips on this?

Here's how its running at the mo:

Macbook 2.2
2 gig ram
Frite Sappgire
Logic Pro 8
Reason 4

Projects specs:
Sample rate :44.1
Bit Depth: 16
Snyc Mode: Internal @ 25fps
Rewire Mode: Live
Rec Delay: - 1800samples
Buffer size: 256 samples

Its been that late that I can press and release a key before the sound is heard..

settign up Reason over rewire has also had another unexpected impact on my logic project.

It's ruined all of the routing. My drums are now being sent to the vocal bus, all of the ultrabeat aux's have diagonal lines goign through them etc...infact I can't hear most of the kit. The kick is completely gone..

I'm a bit stuck. I could delete it all and route it again, but that's mean setting it up again.

Very annoying !

I'm not, and never have been a Reason user Ed.. But a Logic user for years.. I'm taking a few stabs partially in the dark here..

The diagonal lines through channel strips in Logic usually means a previously installed plug-in is no longer available or possibly in your case, there's a conflict between core audio and the saffire..?

The fact your original routing has gone haywire could mean that Logic is acting as a slave to Reason instead of the other way round (?) - Did you launch Logic before Reason as one should?

As for the latency issue, your project buffer within Logic looks ok - so does Reason have an internal buffer option that may be compounding the problem?

Like I said, shots in the dark..

People still do stuff at 16 bits?

(sorry not useful but I don't use logic and had an urge to post)

[sureno]

are you using ad limit, have you tried using latency comp button? like modz1 all shots in the dark and dont mean to teach you to suck eggs either Ed

this is a great plug as well http://www.expert-sleepers.co.uk/latencyfixer.html
for more complex routing such as external and rewire
a good tool to measure latency is http://www.artificialaudio.com/pluginmenu/1

I am 100% sure you know how to do this already Ed of course ...but watching these videos might highlight something, a step you might have missed along the way...maybe...???

Hi Modz. I believe it's impossible to open the programs in the order you mentioned. If you do so, the rewire bridge isn't built. There's no sync of time or passing of audio and midi. Logic has to be first (master).
When you rewire an application, it inherits the settings of the master source. So all internal audio spec/setup options are controlled by one app. Can you imagine what would happen if you tried to run two different clock rates

The routing problem started when I created aux in's for rewire inputs.

Paul, as far as I'm aware, low latency mode in Logic only deals with latency caused by built in plugs. I tried it under rewire and it made no difference to the delay time.

Trev, main reason for not upping the def is because I'm not lucky enough to have an 8core macpro with endless amounts of ram. When it comes to doing the final business, I'll go hell for leather on buffer size and prey everything works at 24/96 !

I'll watch the vids, but I'm pretty sure I've not missed anything. There's more to it I found just, but I'll get back to you shortly after watching !

[sureno]

the plugs i mention can help, it looks like a logic thing from searching around and the only resolve was to measure latency in samples and compensate using the plugs? have you tried it in a fresh project to see if its just project related?

erm, think that's what I said Ed.. Logic first...

Wasn't being funny dude. But you said you'd never used Reason before, so I wasn't sure if you knew how the system works..hence why I explained why it doesn't work.

I've got the latency into just about a usable state, but the way it's messed with the routing has baffled me !

there's only one way to settle this......
Gladiators Ready......
Contenders Ready.......
Dualing sticks ready........
(get out sureno and mind your own business)

[EdRyan]

lol. I'm sure Modz knew it wasn't meant lik that anyway. Just being crystal clear, so that obnoxious ,cheeky trouble makers such as Sureno couldn't twist it

ps. I wanna be Wolf

[modz1]

he he he.. crystal clear is cool Ed.. Now, let's have that cheeky lad Sureno in the naughty corner for 10 minutes

[sureno]

who me...........................

[EdRyan]

Still no solution. Might pop into the apple store on the way home to see if one of the producer guys there has any idea...
