hey!

when i play complex songs in reason (several tracks and a lot of effects and stuff) the sound begins to "lag" and there are some strange noises mixing into the sound.
i think my pc should be able to handle this (ive got enough RAM and my soundcard should be good enough too)
i already tried to set down the sample rate because a friend of mine said so but it didnt work
perhaps it has somethin to do with ASIO4ALL which is this program to reduce the latency because i use a MIDI-keyboard
i hope someone can help me quickly because on the weekend i want to work with two other guys and at least two pcs and a laggy sound would destroy
everything

greetings

When you say you've got enough ram, how much do you have? You should have at least 3 gb's. Now, when you use asio4all, you still can set the buffer samples. From the audio window (edit>preferences>audio) select "control panel."

Go into your preferences and then general and change your CPU usage to the appropriate level and then go into the audio preferences and change your sample rate to the lowest one.

If this doesnt work then you need more RAM

Also, youve probably tried this but shut down all other programs your using.

at least 3gb of ram? 32bit computers can't utilize more than that, so unless you're using a 64bit machine... you're limited to around 3/4gb ram. 64 bit machines can hold up to 128gb ram i think.

A 32 bit system will recognize up to 3.5 gb (windows). And of course it depends on how much stuff you've got going on. If you've a bunch of processors/combinators/fx.....and so on rewired into a DAW with more tracks, you need a lot of memory. Or at least my pc does.

I have problems with this laggy / crackling sound as well on my MacBook running Reason 3. The sample rate is at 44100, my usage limit is at 95%, but the only thing that seems to help reduce this noise is increasing the buffer.

I've done this to reduce noise, and it's worked well so far. My only question is the impact this has upon my interactions with Reason. I noticed the Latency and Latency Compensation went up with the buffer size; will this affect actions or inputs from my midi controller in realtime?

My laptop is over a year old, so it maxes out at 2 Gigs of RAM (which I'm already running). Short of buying a new computer, is there anything else I can do to keep this lagging away long enough to finish my tracks and export with a clean sound? Any help or suggestions would be appreciated.

see if there are any asio drivers you can install.

Changing the CPU-Limit of Reason has absolutely NO effect to the performance of Reason!! It's just to avoid a hanging system, when the CPU usage raises over a critical value. Let it at 80 or 90%.

Changing the sample rate can only help a little bit, too.

Increasing the RAM is only useful, if you have very less RAM like 1 GB or so. Reason doesn't need that much RAM, except you have very many samples loaded. Effects and Synths (nearly) don't need RAM.

The only real thing you can do is:
to go to the configuration of ASIO4All and set the latency/samplebuffer size to a higher value. If you don't use ASIO4All, you have to set it higher in the Reason audio preferences. If you have another ASIO driver, there must be another config tool to set the latency/samplebuffer size. Anyway, if you don't have already, you just try to use ASIO4ALL or another ASIO driver for your soundcard, because ASIO driver perform better and you can use lower latencies/samplebuffer sizes without crackles/lags.

Thanks for the suggestions. They have helped some, but for some reason I'm still getting the lagging / crackling noises when I play my more complex tracks.

Being that I'm on a mac, I can't run ASIO4ALL. I can't find any options to increase the buffer in my Mac Core Audio Drivers, so I've increased the buffer size in Reason. But to stop the crackling / lagging noise, the buffer needs to be too high (I say "too high" because with the buffer increased like this, any small changes such as muting / solo'ing tracks are noticeably delayed, and the change occurs not at the timing I had intended).

I don't know if my computer is too outdated, but it's only a year old (MacBook with OSX 10.4, 2.16 GHz Intel Duo, 2 gigs RAM). Since buying a new laptop isn't really feasible right now, I'm trying to troubleshoot this problem any way that I can. Here's a couple of my ideas:

One problem is that my hard drive is waaaay full, like only 3 gigs left out of a couple hundred gig capacity. Does this affect my virtual memory, and then processing power going into / sound coming out of Reason? If this might be the problem, can I just move my files onto an external hard drive to bypass this problem?

The lag / crackle comes at the highest decibel points in my tracks / loops, which are also the points where the most instruments and samples are being used. I've double checked the volume from each device into the virtual mixer and even used the limiter to be sure nothing should be clipping. Is there any way that the Reason sound output might be clipping en route through my sound card and out of the headphones jack? If this is the case, can I bypass this problem by routing the sound through another audio output than my headphones jack, such as an extra audio interface like my old MBoxes, etc?

Any other suggestions would be helpful. I've brought the .rns files onto a friend's computer, and they ran without any problems. I really appreciate the help.

Lance

Got this from another thread:

I'm not sure exactly how to change the IDE settings but Google is your friend

An you might also want to get an external soundcard for your Mac if you don't have a good one. You can get really good deals off ebay and amazon.
