Thanks Very Happy
I have to admit that i thought that those digital circuits classes would´nt be useful until i´ve noticed the flipflops in modular.

Here are the links that inspired me to build this structure.

Basically it is a finite state machine where the combinatorial stage has the functions of increment decrement the current state or reset to zero.

It passed my mind to make the function to program an initial state and the other function to skip n states seems a good idea that i haven´t imagined, BUT

flip flops are capable of remembering only 2 states hence the circuit quickly becomes imensely cluttered so i am already thinking to use the clocked sample and hold module as the memory for storing the state because it´s the analog of using 8 flipflops in the finite state machine, so probably i won´t invest more time in binary machines after this one.

The main objective for this is to create a sucession of states in the range of 0 to N-1 to ouput to a second stage that associates those N events to notes in a scale for generating complex live arpegios.

The original motivation for this was first the subarppegio function available only in the nord lead and also by hearing the arpeggios from sources like Rio album from Duran Duran and some Goa from Shakta and Moonweed as an example... which were programmed by hand, but the real fun is to develop some mathematical pattern to occasionally and ramdomly change some notes to avoid repetitive behavior... Very Happy

Welcome bantri, some iinteresting stuff you posted.

When you make a new message in the right thread copying the contents of the first mail in this thread I'll then remove this whole thread (it doesn't seem to be possibel for me to move an indivudual message to another thread without becoming the author).

I'm not sure whether this belongs in the noodle section (as that's supposed to be more musically directed). Building blocks seems more apropriate to me (being of a more technical nature) - what do you think ?

Jan.

Yup, it makes sense to move the digital circuit and n bit counter topics to the building blocks section... thanks...

i just reedited the digital circuit and n bit counter topics in the building blocks section, it is ok to remove them from the sequencer section... thanks
