The IF109 is a module that combines two important synthesizer functions. It produces trigger and gate signals whenever a 'timing' signal crosses a user-defined threshold. At the same time, the trigger pulse fires a high-performance sample-and-hold circuit that sampels a second 'main' signal input.
The [TIMING SIGNAL] waveform would, typically, be a waveform with a -5V to +5V swing. This signal can range in frequency from around 0Hz to well over 5kHz. The triangle output from a good LFO would be a good example.
The IF 109 can be used as a regular Sample & Hold module by patching the signal to be sampled to both the [TIMING SIGNAL] and [IN] inputs.
Ian Fritz says of this module, "One goal in designing this module was to be able to generate what are known as "Poincare sections" and "first return maps" in the jargon of chaos theory. In a driven system such as the IF108-ChaQuO or IF120-Chaotica circuits, this involves producing sequences of output voltages obtained by sampling the flow signals every time the driving signal crosses a particular phase value."
