There’s a thread at

> I remember that a Pianoteq’s engineer told me that running in aarch64 would give 10% up of performance, so perhaps this is enough to run without xruns in zynthian. Anyway, it will run very close to the limit. Using Pi5 certainly will solve the issue because it almost doubles CPU power. Regards,

That to me implies that there should-might be some extra CPU ‘left over’, and if I dare to quantify something so vague, maybe a third of the CPU(s) is available. Maybe not if you hold down all 88 keys!

The whole thread is relevant to this question.
