Midi-Gate-Trigger

Hi Mike,
maybe you can help me... I have on 12.06 a gig... I programmed a really cool patch for that... but after 20 - 30 Minutes my CPU usage gets high up to 100% (bevore the liveset has 30%) I use 4 Instances of my Midi-Gate-Receive Unit & 1 Midi-Gate-Send Unit.
When I then open the Midi-Gate-Receive  unit with the max editor and press "SAVE" the cpu Usage gets down to 30% - I dont understand it... I made differnt kinds of workarounds to reduce cpu usage... but up to now it is still the same... how ever...maybe first I describe the Idea behind the patch... and maybe you will get interestet in it:
 
The Idea for my Midigate (how it works):
In my Drumtrack is the "Midigate-send" Patch, there you can choose which Notes will send to my "midigate-receive" Patch. You can select 5 notes (aka 5 chanals--BD SN TOM RIM CLAP or so), in this patch only the velocitys will be sendt - not the notes > to reduce TRAFFIC (reduce audiable clicks that are coming when I send many data from one m4l patch to a nother --- Dont know why that so is...)
In my Synthtracks are the "Midigate-receivers" - they collect the Mididata from the Synthtrack-Midiclip (in realtime - so also midikeyboards can be connectet) & the Incoming Drum Velocitys (from "midigate send" on the drum track) trigger the notes with the Drumrack Velocity & Position - IN POLY 6x
That meens - The drums are triggering the Synth with the Drumvelocity and Note Position (time--steps...) but with orginal Synthmidiclip Notes>>> It order the Synthmidiclipnotes in time and Pressure! So the Synths will ever fits to the drums (so I and my "Drummer" can Jam in Realtime! and Melody and Beat fit to gether ---big phat groove!). jep it grooves (to get it worked you increase the AMP-Release of your synth...or just take a notelength plug after the plug >>> I reducet the Noteduration to ZERO - I thougt it could save me from 100% cpu usage...but it didn´t)

(on my dualcore laptop I get a error message when i load this patches in my liveset --- crash!... with my quadcore audioworkstation I have no problem with that....how ever... sick!)
