Are Dp4 Problems - Midi-related, Are poor midi implementation the culprit Options

[dixiechicken]

I'd like comments to these observations. Has anybody noticed this.

For me all the problems I have in DP4, CPU spiking,
my 828 firewire going dead == no activity lights while playing back sequences,
playback stutter and the famous SBFH etc.

Seems to crop up after I have been doing anything in midi. But I have yet to deduce a pattern to it all.

Just spent 5 hours straight with looping drum-patterns, Recording gtr-tracks, soundbite editing etc.
In a small project. Not a single hiccup. Processor cpu load way down low.

Just before this 5 hour strech I had to "force quit" DP4 in the same small project.
(listened to the midi-tracks & muted them to work the audio)
I did NOT even reboot my imac, just rebooted DP4.

I will post a follow up to this one - directly below - not to be too longwinded in a single post.

Cheers: Dixiechicken

Hi dixiechicken,

Also had similar problems with MIDI in DP4.

What MIDI Interface are you using ?

I was using MIDEX 8 Interface and a MOTU 828 for audio - did some investigation and found that there were spikes in the MIDIServer CPU usage - using the "top" command in a terminal window.
MOTU blamed these on beta drivers !

Took the MIDEX 8 back and got one of the new MOTU Express 128 interfaces and it runs alot better - not really thrashed it yet but - rechecked the MIDIServer usage and its really low without any spikes.

I'll repost if I have any further problems.

Cheers
