Loop problem

[Blomski]

Hi,

I have a problem with pro tools LE on a mini mac OSX 10.4.9
Mini mac is single core and has 2 GB ram.

I use this mac mini for an Art instalation.

let me explain;

An artist made a huge cloud of spinnaker. It's blown up with air by a ventilator. There are 32 TL's in it and near the installation there are some speakers.

The vent and TL's are on a dimmer pack witch is controlled by a LanBox. This lanbox controlls the dimmer via DMX and sends cue's. The cue's are for the TL and vent. It tells them when to dim light and when to stop and start the vent.
The effect is a breathing cloud witch light's up and go light's out, in combination with audio.

for a small picture -> http://www.brabantsdagblad.nl/regios...cle1238077.ece


Now here is the point.

I made 1 stereo loop of 16 seconds in pro tools and i command the cue's of the lanbox via midi.
this are some controller numbers for executing the cue's in the lanbox to control the light and fan.

BUT, after 2.5 hours (more or less), pro tools is hanging and give an error;

A CPU overload error occured. If this happend often, try increase the H/W Buffer Size” in the Playback Engine Dialog or remove some plug-ins (-6101)

and

CPU usage is holding off audio. Remove some plug-ins, delete some tracks, or increase the H/W buffer Size in the Playback Engine Dialog (-6104)


Well the buffer size is at his top 2048.

Why does pro tools do this? I also used digidesign advise of disable spotlight etc.
I don't get it. There is enough CPU power to loop this and pro tools still crashes.

Who can give me an answer?

Pro tools LE 7.1.1.
intel mini mac OSX 10.4.9
2 GB ram
MBOX 2


thanx in advance.

Welcome to the DUC, Blomski.

This is the PT TDM forum. Please note that there is a forum dedicated to ProTools LE and its various hardware options — such as the Mbox, in your case. (Scroll down from from the DUC’s main page and you’ll see it).

While most of the PT software is the same for both platforms, each has its own set of exclusive compatibility requirements, features, issues and problems. Therefore, most answers to such will vary also — highlighting the wisdom of posting on the appropriate forum.


As for your issue…

Read the General Troubleshooting sticky post (by Digidesign) found at the top of every DUC page. Follow its directions.


PS1: OSX 10.4.9 hasn’t been qualified by Digidesign.

Ow now I see Well it was late.
TDM is somewhat more epensive for an art project

Combo installer I was aware of, that aint the problem.
