- An analog-digital converter (ADC) that extracts bit information by converting the input voltage into a digital value
- Digital-to-analog converter (DAC) that outputs the corresponding voltage from the input bit information
It is a conversion module consisting of. It can be used in various ways, such as inputting audio to change the sound by bit crushing or exchanging bits, and outputting a gate sequence by converting LFO or random voltage into bit information.
Drezno is also a signal conversion interface for the Leibniz Binary Subsystem, which is planned as a series of modules that perform 8-bit signal processing.
On the right side of Drezno, gates are input to 0 to 7 to represent 8-bit binary data, and it is taken out as a voltage signal (digital-analog conversion, DAC).
The setting of GAIN and OFFSET on both ADC / DAC side has a great influence on the converted signal. You can also use the clipping effect positively to distort the signal.
When you press the LINK button, the 8 gates that are the output of the ADC are directly input to the DAC by internal connection. As a result, the output from the DAC will convert the input signal of the ADC into 8-bit data and then output it.Bit reduction

With, the ADC output is processed by Lipsk and then internally connected to the DAC input in Link mode.
Conversion in ADC and DAC is performed at fixed time intervals, but it is decided to do this.ク ロ ッ ク
is. The ADC and DAC have separate clock inputs, but if not patched they will run on the internal clock. Since the internal clock runs at a very high speed of 2MHz, it is possible to accurately capture the time change of audio and avoid alias noise. If you put a square wave of a slow oscillator in the clockSample rate reduction
It becomes. Also, when LFO or a voltage that moves randomly is input to the ADC and a clock is input at the timing that becomes the rhythm grid, each output of the ADC is unique.Rhythm generator
* The output when using the high-speed internal clock cannot be used as a gate that triggers something. Be sure to use an external clock if you want to output a normal gate sequence (not audio rate).
Other tips that make Drezno's patch interesting are: As you experiment with lots of patches, you'll find your favorite use.
- Try changing GAIN and OFFSET.
- Modulate the input signal amount with VCA
- Try to patch even one ADC output somewhere to the DAC input without linking
- Combine with logic modules
- In ADC, when inputting LFO etc., the larger digit changes slowly and the smaller digit changes busy.
- In DACs, the higher order bits have a greater effect on the signal
