Hi all
I'm trying to wrap my head around the midi2cv circuit from the following link:
http://musicfromouterspace.com/analogsynth_new/THE_CAVE/MIDI to CV Old Design I/midi2cv.htm
The explanation provided on the page is very good, but there is something that
I don't understand.
According to the explanation, the circuit uses a cd4520 binary counter to "count from 0 to 248".
This is where I get lost.
Of course I checked the datasheet and searched for tutorials etc. but from what I can see, the maximum number that can be counted with a 4-bit binary counter is 15. (full range: 0-15)
I can see how one could link several counters in order to increase the overall count, but how does one arrive at the exact number of 248?
I tried to figure it from the circuit schematic, but that did not make me any wiser.
Any explanation would be greatly appreciated.
Cheers!
