Sleeper awakes is a 12hp dual Lo-fi sampler based on the ISD1820 IC which is an old answering machine chip. It is inspired by several other projects based on the ISD1820 chip (Lonershy and BASTL builds comes to mind but also others). Each channel is identical to each other. There is a mixer combining both dry inputs with the sampler outputs. The individual outs only contain the sampler out signal. Each output of each channel is cross modulation the channel next to it in, so 1-2 modulate eachothers CV input. Inserting a cablei into a CV in jack breaks this (inter)connection. 

Each channel has an input and an output. A pitch knob with a dedicated attenuated cv attached to it. A filter with lowpass to the left and high pass to the right. It also has a dedicated trig in jack with tactile switch for these functions: record in, momentary play and full play of the sample. The trig inputs need a +5v gate to be able to operate. There is also a Loop switch which makes it play the sample over and over. For more info on functions check out my YouTube video on Beneath the Bush of Ghosts which is a quad version of this module. 

As a “bonus” I include a electro magnetic stereo pick up made of inductors. You can use this to sample strange noises from your phone (or other electrical devises), which rests easy if the module is mounted horizontally. The pick ups are normaled to each input, so inserting a cable here will remove the function of the pic ups entirely. 

In order to record you need to turn loop, switch off, set the pitch to around the 10 to 2 o’clock (you can experiment with this), CV knob usually influence sample speed so make sure it is full CCV. Insert an input signal hit record, the LED will flash, when it flashes again the memory of the chip should be full. It’s a simple as that!
