Phatty is a library editor for the Moog Little Phatty. It has been designed to work together with the synth by providing an easy edition of the hidden parameters. Besides, you will be able to rename and rearrange presets.

Phatty is a Python package that is installed the standard way with python3 setup.py install. However, as it contains desktop application related resources, it is installed with make.

The package dependencies for Debian based distributions are:

• make
• python3
• python3-setuptools
• python3-mido
• python3-rtmidi
• python3-setproctitle

You can easily install them by running sudo apt-get install make python3 python3-setuptools python3-mido python3-rtmidi python3-setproctitle.

To install Phatty symply run make && sudo make install.

If you are on Linux, you will probably want to increase the MIDI buffer used in the Sequencer API, as the rtmidi library uses it and it is only 4 KiB, which causes overflows and loss of data. The recommended solution is to create the fle /etc/modprobe.d/local.conf with the following content, which will load the snd_seq_midi module with 64 KiB of default buffer size.

options snd_seq_midi output_buffer_size=65536

At the moment, the underlying MIDI libraries do not raise an error if the synth is disconnected. Thus, neither the application can be aware of the error nor the user get any error message.
