Any tricks dealing with DSP allocation?
« on: February 24, 2016, 09:26:47 PM »

I have 5 mix cards in a session just shy of 64 tracks, everything works great except tools 5.1.3 will not let me add additional effects such as pitch blender, TCI, GRM or even H-TDM even though the activity monitor shows 3 unused DSP slots. it will let me add basic plug ins like eq's and compressors but not the bigger effects.

This is a problem I run into on some sessions, and I cant figure out why or even, what the common factor is?

  :o

As always thanks for all your amazing help!

You could try moving the tracks with the most 'heavy duty' plugins to the far left (mix window) of the session, as this supposedly allows the plugs to load in a more DSP efficient manner.

Use 'Aux Ins' with effects when you can... so you can 'send' multiple channels to a single effect, so instead of putting a delay/reverb/whatever on individual channels, 'send' the channels a single effect.

Also you could start bouncing tracks to stereo 'stems'... like a pairs of background vocals, acoustic guitars, synths or whatever would be appropriate... then you can delete (or 'make inactive'/'hide') those tracks and associated effects... This will also simplify the session considerably and make 'Mixing' easier/ more fun. Do a 'save as' first, in case you need to rebalance at some point.   

Time to add the other 2 Mix cards as well!! ;D ;D

Wow thanks for the tip, I did not know about the left side trick. Everything else is I have been doing already for quite a while, except for some effects that tend to get overloaded loosing quality and definition that I keep on individual tracks.

I have two more cards but simply have not gotten around to making a 7 node cable even though I have the parts, kinda worried I will short something out. If I had the two extra cards installed in the expansion chassis none of this would be an issue as my total DSP would exceed my work flow maximums.   ;D

Yeah, going from 5 to 7 cards made a noticeable difference for me. There are still limits of coarse but there is a LOT more breathing room! ;D

I DO bump into the RTAS/CPU ceiling from time to time so I try to avoid RTAS when I can.

Believe me, I'm ALL TOO FAMILIAR with THIS scenario!! Haha! ;D ... But hey, If Knezzen can do it can't be THAT hard!!! Haha! ;D ;D ;D

Actually Knezzen has a fairly descriptive 'tutorial' of sorts floating around here somewhere that you've probably seen at some point.
