AudioGridder - Open Source Offloading to Another Computer

So, Logic on Mac OS was doing this a while back - using what they called nodes. Where you could offload Logic plugins to another Mac if you were running short on processing power. I know with G5"s and even Core2Duo Intel processors running out of steam - was still an issue. Newer machines seem to have remedied that. And the M1 architecture is looking to make that old news. However if you maybe have something cool in another box - like maybe a Scope Card or UAD hardware - this may be an easy way to use a VST or AU in your arrangement that maps over Ethernet to bring in your audio seamlessly.

Last year I've moved most of my music production to a Mac. I still have some older plug-ins including a TC Powercore (with the Virus plug-in) that I wanted to use so I set them up on a Windows computer. Audiogridder seemed like the solution. It was an earlier version so I'll have to try it again but it wasn't reliable for me. My current solution is actually running Gig Performer on the Windows PC and treating it like a sound module or external effects unit. It's not perfect but it has been reliable enough for me to keep using some of the older plug-ins and instruments for now.

Soundgrid user here. I pull the soundgrid output from the remote VST host (e.g. Gig Performer) into an input in my DAW.

 

Still need to run a remote desktop session, and there's zero recall from the DAW side other than "send MIDI to this output on this channel, and receive audio back from this soundgrid input".

 

So, I think of it the same way Mike does: it's an external "synth", but everything (MIDI and audio) moves over Ethernet. That much is easy ;)

 

Will have to see how this compares.

I make software noises.

I always wondered why DAW do not do this automatically, i wasn't aware that Logic was able to do it.

Tons of people use VEP for running huge sample libraries in multiple computers, i think it something still needed; computer history teach that there is no such thing like "enough computing power".

I saw a thread about this on another site last week, so decided to download and install on a Windows machine. I didn't want to move all my plugins over to another server, so I'm just running it as a local server on my DAW machine. In limited testing, I have to say I'm very impressed with the overall performance and stability. I can run multiple instances of Diva in Divine mode, and other CPU-hungry plugins, without a hiccup. Patches that previously caused audio stuttering on my system no longer glitch at all. I'm not sure how it works its magic, but color me suitably impressed so far.

Not that I verified it, but I applaud the Open Sourceness of this tool, which I cannot try because since very long I don't run Apples. The idea exists and is technically depending on a few main hard givens, namely network delay, uncertainty and the absence or presence of re-sampling.

 

The network has a minimum package size which on common 1Gb Ethernet gives a certain minimum (noticeable) latency. This becomes worse when using a network protocol which allows for network error detection and correction. No problem for mixing or sequencing, but for live playing: not great.

 

Using only one audio interface, it is possible to set up and audio network signal graph where thee is sample for sample accurate processing, so that except for delay there is no quality difference between a single machine or networked multiple machine solution to run a certain audio project. This may incur additional delay, all the more when allowing for network error correction, but it becomes a different story when nodes run at the audio clock of each their own audio interface: sample stretching always influences signal integrity, which can be o.k. for monitoring but probably not for you great mixdown.
