The Noise Engineering Pons Asinorum is a compact four-channel linear multimode envelope generator and LFO. It features three different envelope shapes and voltage controlled cycle length. The module is operated by a unique single-encoder. Each channel provides his own trigger input, and can be set separately to envelope mode or to LFO mode, giving a lot of flexibility.
The Noise Engineering Pons Asinorum is a multimode function generator.
It features four identical channels, which can be selected using the select button. The LEDs for selected channels will light in red or purple, depending on cycle lenth.
Operating the single-encoder, the cycle lentgh of selected channels can be adjusted. Pressing the encoder resets the value to its minimum. The cycle length of all four channels can be voltage controlled thanks to the according CV inputs.
The response range of each channel can be changed from short to long, by holding the encoder down for about two seconds and then pressing the channel button.
The Hit button is used to trigger selected channels in envelope mode or to reset the phase in LFO mode. This mode can be activated by holding Hit for two seconds.
The Mode switch allows to switch all four channels between ramp up, up/down, and ramp down modes.
There is also a hidden Sample and Hold mode. By holding Hit down on power up, it is possible to change the CV response from continuous to sample and hold. On startup, after the initial LED flashing, all four channel LEDs will flash blue to indicate sample and hold mode or red for continuous mode.
