Very cool!

two quick questions...

when in random mode although D5 and D6's inputs are not used, we still have 6 outputs correct?

and

for the division inputs, zero volts means a divide by one right? so t ...

Haven't tried this design yet, but will soon as its real compact and simple

http://members.cox.net/synthfred/h_enf121.htm

looks like i have some bad timing...

what is the tempo range for the clock?
and about what is the highest frequency it can accept in the division mode?

really an awesome project. so much functionality crammed into such a compact boar ...

a lot of people call these "attenuverters" incase you are familiar with that parlance

check out this schematic from tom bugs

if the square waves are going to be fixed frequency like they would be in a top octave synth, you could just use a simple one resistor, one capacitor filter for each note

the x-y pad looks interesting
i wonder how fragile the pad is
also any suggestion on a simple gate out?

if i dont have trimpots, what would be the best value to replace the trimpot and the 10k resistor before it? 50k?

thanks

so i just made a parts order a couple days ago and totally forgot to pick up those chips! oops.

pretty skeptical of this circuit... but looks like ill get some lm1496's in my next parts order to try it out anyways

i do love the 4046 but my favorite uses for it go beyond lunetta-like simplicity

okay i tested it out and it works although i need to do more experimentation to find the best cap values to use

If it's not too much trouble, I'd be really interested to see your schematic with the ins and outs, once you have it up and running too.
