To improve the CPU usage of SIGNAL, please try the following:
- Increase your buffer size to at least 512 samples.
- Minimize the release time of volume envelopes wherever possible.
- Minimize the use of time based effects on the Global and Pulse Engine levels.
- Reduce the max number of voices used by a Pulse Engine (click the gear icon on the top right corner of either Pulse Engine A or B).
- Minimize SIGNAL's GUI within Kontakt when it's not being used, then close the Kontakt GUI.
We also recommend running your DAW in 64-bit.
