N bits Up/Down/Both synchronous binary flip flop counter

[bantri]

An attempt to supersede the default binary couter module adding an up/down input and the possibility to expand no N bits in modular demo...

Thanks
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...

Here is the option i mentioned using the sample and hold module instead of flip flops (thus allowing a less cluttered structure), it consists of a finite state machine that has an initial load value, upper and lower bound detection every time the state gets out of bounds it triggers one of four increment/decrement values.

Probably the next step on the research will be using the sequencer value module instead of the SH module to store 16 individual states.

I currently don´t know if it´s possible but it will be something like setting each of the inputs with a sequence like
1,5,2,3,7,4,8,-1(<EndOfCycle),x,x,x,x,x,x,x,x(<DontCare)
allowing to set individually the next jump for every state thus allowing the most flexible state machine as possible and later cascading/summing two of those circuits, so after the secondary completes one complete cycle it advances the primary to the next state, then your going to hear some really nice trance inducing patterns.

Ok, I made a stupid remark somewhere and things got messed up a bit as a result, sorry.

I locked the original threads, didn't know what else to do.
