A common problem many people face with Diva, is that it uses so much CPU that it becomes unusable. But there are some things you can do in Diva to reduce the CPU usage so a patch at least becomes playable.
The things you can do to reduce the CPU usage in Diva are:
1. Use less oversampling.
2. Don't use too long release times (if you do, then make sure to use longer notes/chords to prevent Diva using up all the voices too fast, which is what often causes CPU spikes).
3. Don't play chords too quickly (which goes hand in hand with what I wrote above).
4. Use the Multicore option if you have a multicore processor (but still be mindful when using this feature, it can wear out your processor and in some cases cause PC shutdowns if the CPU load gets too intense for a too long period of time).
5. Something I missed to mention in the video, is to use lower polyphony. The more voices you allow Diva to use, the more CPU Diva will use. If you set Diva to use 16 voices polyphony and at the same time utilize a long release time, then Diva is going to eat up CPU resources very quickly (a long release time eats up voices fast, which in turn makes Diva use more CPU).
6. Bounce (i.e record to .wav sample) your sounds.
7. Bonus: Use Poly2 mode, it will cut off the release to make the sound less messy. This
will help to reduce some CPU usage also.
8. Bonus: Certain filter modules uses more CPU. The multimode filter is the one that uses the most CPU on my system. The Cascade (Jupiter-8/Juno-60) filter uses the least amount of CPU on my system. The same also applies to some of the high pass filters. If possible, use the Cascade filter (if it also uses the least amount of CPU on your system). It's a great sounding filter anyways and I use it most of the times when I use Diva.
