Fonitronik 4U ADC Sequencer (Proof of Life)


Published on Aug 18, 2016 fonitronik

"This is just a short proof of life of my 4U ADC Pattern Sequencer in Serge format. It runs in it's basic mode.
1st step is set to always ON, whereas steps 2-7 are controlled by the ADC. The ADC gets a voltage from the DUSG (LFO) and converts it to an 8-bit word that corresponds with the 8 steps (=pattern). The ADCs 8-bit pattern is loaded by a latch (triggered by a division of the clock signal).

The sequencer is controlling a Thomas Henry VCO 555 (CV) and a LPG 292C (trigger), whereas the DUSG (LFO) is changing the PW of the clock as well.

BTW the clock is PWM'd, and the trigger output of the sequencer follows the clock signals pulse width, this the changes in the LPGs opening times ;P"
