Hi everyone,
I'm working on a 16-channel mixer with stereo bus sends...I originally didn't think it would take up much DSP, but it now is. I've been putting DynVoicesOfParent modules set to 0 on every channel and every bus send, but it hasn't helped much -- with only a mute button, volume, pan, and a send to main mix button, each channel is taking up a large amount of DSP power. In fact, when I put DynVoicesOfParent ON THE ENTIRE DEVICE and set it 0, this mixer was STILL taking up 3 notches of my 22 DSPs. Why is this happening??
Does anyone have any tips? I'm getting pretty frustrated. I tried "Optimize - XTC compatible" but XTC on a mixer doesn't work, and it threw up lots of errors. I also tried deleting unused panels attached to the internal circuts, but all those run on ASync so it didn't make much difference. I have no idea why everything is taking up so much DSP power.
Thanks in advance,
Shayne

Hey,
Its pretty hard to help you with that one, since you dont tell which modules you use.
But DynVoicesOfParent dont have any impact on modules which uses alot of DSP ram.
Cheers

Most of the device is made up of gain controls, panners, 1/4 switches, 4/1 adders, and insert slots. I don't think the insert slots take up any DSP when they're not loaded, and the rest of the modules aren't fully turning off.

Sounds weird.
Unfortunately I cant help you without the actual device.
Are you using the softclip module?
You could replace some of the modules, like the 24dB gain module with Add02L (that will give you 6dB gain).
I dont have access to the SDK so I dont know which modules you have - you have probably more than me.
Cheers

I meant gain control as in Mixer Master Gain -- i.e., volume fader.
J9k graciously offered to check out my device, but if you want a copy of it too, I'd be happy to give it to you. It's 10MB, though (when I initially made the device I inserted pan modules and adding modules that all had their own surfaces, and now I'm having to go through the device and delete all those sufaces -- it's a lot of work and hasn't been finished yet, so it's bigger than it should be; doesn't affect DSP load, though).

Okay, since J9k offered you help, I dont need the actual device. But If you have any questions then dont hesitate to contact me.
Cheers
