FEATURES ON THE PCB
There are a few features on the printed circuit board (PCB) that you can only access with the cabinet
lid removed; so open it up and take a look inside.
1. BATTERY HOLDER; INSTALLING THE BATTERY
We recommend you power your Macchiato Mini-Synth with a 9V DC power supply (“wall wart”; see
above), but you can install a 9V battery for backup power or mobile use. When a power supply is
plugged in, the battery is disconnected. Do not waste your money on cheap batteries! You will regret it.
We recommend Energizer alkaline batteries. The on-board speaker will drain your battery a lot faster
than headphones will. When the battery gets low, the LED will grow dim and your synth will start to go
haywire. Replace the battery immediately, or better, switch to a 9V DC power supply.
Do not store your Macchiato for an extended period with a battery installed! The battery will eventually
leak and could damage your synth.
To install a battery:
a. Turn off the Mini-Synth.
b. Lift the lid up and off of the plastic cabinet, or open the front tabs of your cardstock cabinet.
c. Insert the battery into the battery holder until the contacts engage and snap together.
d. Carefully push the battery bottom down into the battery holder until it snaps into place.
To remove the battery, you might need to pry the holder away from the battery bottom.
2. ISP HEADER; FLASHING NEW PROGRAMS
See that cluster of six pins sticking up to the right of the Zeppelin serial number? These are the In-System
Programming (ISP) header pins that allow you to communicate with the microcontroller that runs your
synth. You use an inexpensive device called a programmer that connects the ISP header to a USB port
on your computer. Then, you can download new synthesizer programs from Zeppelin Design Labs as
we publish them from time to time and upload (“flash”) them to your synth!
We host the Macchiato source code and all supporting files at www.Github.com/zeppelindesignlabs .
Please go to the Macchiato Mini-Synth repository page now and read the README.md file for detailed,
current instructions on obtaining and flashing new programs.
The Macchiato was released on February 1, 2017. As of this writing, no software updates exist
beyond the program already on your synth. You can, however, write your own updates! Read on.
