Editing Using the FV-1 simulator (section)

== The crystal setting ==

The '''Clock''' section changes the rate the simulated chip runs at, the same way swapping the crystal does on real hardware.  The standard FV-1 clock is 32.768 kHz.

Your program does not change — it still runs 128 instructions per sample.  What changes is everything measured in samples:

* Delay times scale with the clock.  The FV-1 has a fixed 32768 words of delay memory, so a faster clock buys you proportionally ''less'' delay time.  The readout under the selector shows the maximum delay and Nyquist frequency for the rate you have chosen.
* LFO sweeps scale too, so a chorus tuned at 32.768 kHz will modulate faster at 48 kHz.

Changing the crystal rebuilds the audio engine, which clears delay memory.
