4046 Pitch Tracker in its Simplicity

Here's another clip demonstrating how the 4046 pitch tracker adds tonal variety to the simplest of patches. You do not have to build a ton of intricate modules to ROCK.  Multiply this concept with more oscillators going into more gates or data selectors like the 4512, 4051, 4052, etc., and make some music.

I have made plenty of complicated patches no doubt; but I like to get the most bang for my buck in a more stripped down way as well.   Must be my "guitarist thinking":  it's not how many or how fast you play the notes.  It how you get the most tone dripping from each note.

Tiny Build

I am super slowly building a mini lunetta.  I am going to use an old sega genesis cart box for the enclosure.  The perf holds 6 chips so far.





Julu 2012 update:  Turned out to be to darn small!  See following posts to check out the final build!

Using the 4094 as controller for the 4512

Here's a lil' video of my lunetta playing a tune with the following ics: 1. 3 oscillators built from the 40106 2. A 4040 divider to provide octaves of the clock source 3. A 4094 to provide the ABC pins of the 4512 ic One clock connects to the 4040. I take 8 outs from that chip and connect them to the 4512. Think of these as the notes to be sequenced. The 4094 has Data and Clock pins that are connected to the remaining two oscillators. Pick any of the outs of the 4094 to influence the ABC pins of the 4512. The 4512 has one output pin so all your bits of sound simply need to go to your mixer/speaker. Get more complicated as you like ;).

Not So Daily Twiddles

Nothing beats getting through a cold on a hot, humid day than heading to the basement for some lunetta action. Ic's used are: 4051, 4094, 4018, probably 2 different gating ic's like the 4070 and 4011, and partway through the clip I send the output to the 4046 pitch tracker module to give some change in freQ.

A quick albeit dark, video LOL

I've been stuck in a black hole of sorts but did manage to sneak in some lunetta time. The ics I used: One oscillator as clock source for the 4040, 2 more for the 4094 shift register. These will be the data sources that I connect to the data inputs of the 4512. The ABC controllers of the 4512 are of cource three oscillators but you could mix that up with the outs of the 4094 or other logic. A B and C will dictate which "channel" shows its stuff to the common out pin of the 4512. This output goes to my 4046 pitch tracker to create some of the sweeps you hear. Hope to post more vids soon :)
