Changelog version 2.0
•
CV input added
•
Tracking slightly improved
•
Both switches changed to on/off/on types for two new
features:
◦
Octave down switch middle position: Fundamental note
◦
Octave up switch middle position: Detuned upper octave
Controls
•
SWITCHES:
•
OctDown – Toggles between one octave down,
fundamental note, or two octaves down
•
OctUp – Toggles between on octave up, a detuned mode
(in between on and two octaves), or two octaves up
•
MIX: Blends between octave down and octave up
•
VOLUME: Controls the overall volume
General builds tips
•
Solder the low profile components first, from short to tall
height. Recommended order: resistors, diodes, IC socket, film-
caps, electrolytics, pots and switches
•
CMOS chips are very sensitive to static charges and can be
easily damaged. It's a good idea to wear a anti-static
wristband or at least avoid wearing a wool jumper and petting
your cat/dog while building...
•
Always use sockets for IC chips and transistors to avoid
heating them directly. It also makes it much easier to swap
them out if needed.
•
Pay special attention to the orientation of the diodes and
electrolytics.
•
All PCB's are designed for 16mm Alpha PCB mount angeled
pots. You could also use solder lug type and just tack some
“legs” with short pieces of wire to each pot to mimic a PCB
mount type.
•
The square pad represents pin 1 of each pot.
•
Both pots and switches are meant to be mounted on the
backside (the solder side) of the PCB and soldered from the
front side (component side).
