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

Ok everybody - here's my follow up.
---------------
Went back to my small project, opened it up.
Muted the audio tracks, unmuted the miditracks.

Played the sequence a couple times, and adding another midi-track ( a grand total of six ).
After trying to choose a sound I wanted from my Proteus 2000, midi-gremlins re-appeared with a vengeance.

Moving the mouse ( honest I didnt klick no button Mom ) DP4 started to record my 6:th midi track.
Ordnary playback stutters.
The infamous SBFH keeps popping sometimes now, sometimes then.
Sometimes the transportcontrols work - sometimes not.
Oops... my 6:th midichannel seems to have lost all notes below middle C.
( I use my K2000 as master keyboard -- no cpu spiking though - halleluja )

After 15 minutes of this - poof DP4 call it quits (not that I blame the poor bastard) -
luckily it hasnt affected the stability of my system. (hehe)

Top-stat didnt turn up anything really useful. I misstyped vm_stat, but I'll get better I promise.

Either I have managed to f--k up my simple midi setup royally, or if NOT,
somthing fishy is going on.
Tomorrow I'll eat my vitamins and give it another go.

Observations and comments please!
