Hi everybody!
One of the "Utilities"'s pages shows us the CPU usage and the temperature.
Why does the Wavestate show us this last item?
Is there a maximum temperature that the Korg Wavestate is supposed can resist?

The Wavestate (and Opsix and Modwave) uses a Raspberry Pi compute module as the main CPU (synth engine). It is a quad-core processor made by Broadcom.

Like standard laptop PCs, this CPU has a built in temperature sensor for the chip. If the CPU exceeds around 80C , the CPU logic will reduce the clock speed to prevent overheating - which can damage the CPU.

I think this is the temperature displayed by the Wavestate in the Utilities display.

If I recall, the Pi compute module runs at top speed of 1.2 GHz.
When the 80C temperature is reached, the clocking is reduced - sometimes as low as 300 MHz in a effort to keep the temperature below 80C.

Normally at idle (like a PC) the CPU clock will drop to around 500 - 600 MHz to save power. When generating sounds, it will automatically increase this clock up to the max (1.2 GHz = 1200 MHz) as needed.
