* [[SP0256 Pin-Outs]]
The interface does NOT contain an oscillator. Instead, OSC1 (SP0256 Pin27) is wired to the CPC's 4MHz clock signal (Expansion port Pin50). Thus producing shorter sounds with higher pitch as when using the recommended 3.12MHz oscillator.
Note: The |SPED command inserts a crude software-delay between the separate allophones (ie. it is NOT a hardware-feature that changes OSC1/OSC2 clock speed or so).
