Xequence 2 + AU host - what to do when CPU is maxed out?
![[Deleted User]](https://secure.gravatar.com/avatar/79997512d01432d054cc1030939fecfd/?default=https%3A%2F%2Fvanillicon.com%2F754b9fde9f66b1a64fe680f88084dde6_200.png&rating=g&size=200)
As far as I know, there's no freeze with this setup. So how can this be done? Bounce everything to Audio and move to Cubasis or another DAW? Should I just start in Cubasis and not use the other way, since I'll be bounding to audio at the end anyway?
Questions questions, workflow questions

What host are you using?
Are you only using synths or doing additional audio recording?

Loopy Pro makes a nice Xequence companion. You can easily capture audio tracks to clips then mute the original synths which frees up the CPU but keeps the synths available if you need them again.
I don’t know how intensive those apps are as don’t have them but I also get dsp spikes/crackling if there’s any “graphics” requirements.
You don’t even have to remove them to free up CPU use…this is a key difference between Loopy Pro and many hosts…freeing up the cpu used by muted instruments.
if the issue is memory use, one would need to use fewer instances of the same plugin, though… but could change presets as needed.
Xequence 2 sends song position pointer (SPP) and Loopy Pro's timeline can follow it. So, Loopy can in effect become an audio clip extension for Xequence 2. It's not completely seamless but it works pretty well once you get it set up. I can't search right now, but there's a thread around where this is discussed.

Less FX/Modulation - Lots of plug in fx will do you in, even the internal fx on each individual synth/drum machine/ etc.. so minimize the amount of extra fx used, both internally in the synths, and externally with the amount of Au plug ins. Some FX like AUM’s internal fx are super light, I’m talking more about 3rd party plugins or even lots of moving parts, like modulation/automation. Some FX are way heavier then others.
Change synth or use a place holder - some synths just use a lot of cpu depending on several factors. You can use something super light like KQ-Dixie as a place holder to lighten the load from heavier apps, then bring in the heavier stuff when you want to record it, or whatever.
Clean and clear - make some space by clearing some storage, old apps/pics/offload apps, by clearing websites and cookies in Safari settings, turn device off and then back on in 5-10 minutes will also help with cpu/DSP
Airplane mode - You can always go “airplane mode” which opens up some extra cpu/DSP, it stops bunch of apps and features from constantly fetching data in the background which takes up valuable cpu. This will obviously disconnect the Wi-Fi/etc… but if you are just jamming the vast majority of music apps do not need Wi-Fi.
Audio is lighter than midi - if you have a lot of midi being sent to different synths/etc to trigger them it will start to add up the amount of live processing the device needs to accomplish it. Consider recording an instrument or two in AUM, then loading it as a looping audio file which removes the need for extra live, real time processing, then you can disconnect that midi so it’s not sending or receiving. You can still keep the midi inside xequence 2 to use later or create another audio file, you just lighten the workload by sending less of it at one time.
5b. Midi processing/midi fx - if your are running a bunch of Au midi filtering type apps to add variations, or do different things, this all adds to the real time processing. You can run the midi through the filter (ie. Mozaic, Midigates) and record it into a piano roll or back into xequence 2.

Right on. Cheers @JMcMillanMusic
