Download"Jessie" image and burn to SD Card.

From here we could follow instructions over @LearnAdafruit or keep reading here.

Download THIS new Kernel. Thanks to @adafruit @AdafruitIndustries @limor

Move the kernel file to the boot directory of your "Jessie" SD card.
Insert SD Card in the Pi Zero and power on.

Now we are going to :

1. Install the new kernel we downloaded.
2. backup and install new kernel.
3. Install Overlays & Modules.
4. update the module and reboot

We will need to run the following commands.

cd ~
sudo mv /boot/gadgetkernel.tgz
tar -xvzf gadgetkernel.tgz
sudo mv /boot/kernel.img /boot/kernelbackup.img
sudo mv tmp/boot/kernel.img /boot
sudo mv tmp/boot/overlays/* /boot/overlays
sudo mv tmp/boot/*dtb /boot
sudo cp -R tmp/boot/modules/lib/* /lib
sudo nano /etc/modules

g_midi

Done! we just need to connect PiZero to PC. Now on your computer there will be a new MIDI device . Check the Windows Device Manager.

Software Install:

piStudio Runs with LMMS so we need to Install this to the piZero. Open up a terminal and run the command:

sudo apt-get install lmms

AUDIO:

In order to be able to use the phatDac we will need to set it up.

in order to do this we will need to:

1. connect to the internet.
2. bring up the terminal.
3. Run this code:

curl -sS get.pimoroni.com/phatdac | bash

for manual install we can follow the instruction ove at the POST " Setting up pHAT DAC".

MIDI:

In order to get Midi working we need to boot up the Pi, and type this in a terminal:

sudo nano /boot/config.tx

We will add these two lines:

init_uart_clock=2441406

init_uart_baud=38400

Next, edit the cmdline.txt and inittab.txt to disable the Pi's shell from UART so the port is free for MIDI access. Back-up each file :

sudo cp /boot/cmdline.txt /boot/cmdline.bak

sudo cp /etc/inittab /etc/inittab.bak

Lets edit the cmdline.txt:

sudo nano /boot/cmdline.txt

dwc_otg.lpm_enable=0 bcm2708.uart_clock=3000000 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait

Save and exit, then edit the inittab.txt

sudo nano /etc/inittab

Now look for the line at the bottom that says “ttyAMA0” and remove it or put a hash in front of it like this:

#ttyAMA0

Save and exit, and then restart your Pi. Now the Pi should be able to receive and send communication at 31250 baud, but we need to install a program to handle the MIDI signals. Time to do a little ditty for TTYMidi, a bit of software that creates a serial to ALSA interface on your Pi. Type the following commands into the Pi terminal to download and install ttymidi:

sudo apt-get install libasound2-dev

 wget http://www.varal.org/ttymidi/ttymidi.tar.gz

 tar -zxvf ttymidi.tar.gz

 cd ttymidi/

 make

 sudo make install

Reboot the Pi.
