An unimpressive thingie for playing bits of samples with some level of accuracy.

# Linux installation



Here's how to install dirt under Debian, Ubuntu or a similar distribution:



~~~~sh

sudo apt-get install build-essential libsndfile1-dev libsamplerate0-dev \

                     liblo-dev libjack-jackd2-dev qjackctl jackd git

git clone --recursive https://github.com/tidalcycles/Dirt.git

cd Dirt

make clean; make

~~~~



## Starting Dirt under Linux



First of all, start the "jack" audio layer. The easier way to do this

is with the "qjackctl" app, which you should find in your program

menus under "Sound & Video" or similar. If you have trouble with

qjackctl, you can also try starting jack directly from the

commandline:



~~~~sh

jackd -d alsa &

~~~~



If that doesn't work, you might well have something called

"pulseaudio" in control of your sound. In that case, this should work:



~~~~sh

/usr/bin/pasuspender -- jackd -d alsa &

~~~~



And finally you should be able to start dirt with this:



~~~~sh

cd ~/Dirt

./dirt &

~~~~



If you have problems with jack, try enabling realtime audio, and

adjusting the settings by installing and using the "qjackctl"

software. Some more info can be found in the [Ubuntu Community page for JACK configuration](https://help.ubuntu.com/community/HowToJACKConfiguration)



# MacOS installation



Installing Dirt's dependencies on Mac OS X can be done via homebrew or

MacPorts, but choose only one to avoid conflicts with duplicate system

libraries.



Unless otherwise specified, the below commands should be typed or

pasted into a terminal window.



## Installing dependencies via Homebrew



[Homebrew](http://brew.sh) is a package manager for OS X. It lives

side by side with the native libraries and tools that ship with the

operating system.



To install homebrew:



~~~bash

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

~~~



Initialise homebrew:



~~~bash

brew doctor

~~~



Install Dirt, a synth (well, more of a sampler) made to work with

Tidal. A homebrew 'recipe' for dirt does exist, but that doesn't come

with any sounds to play with, so for now it's probably easiest just

download it all from github and compile it as follows.



Install some libraries which the Dirt synth needs to compile:



~~~bash

brew install liblo libsndfile libsamplerate

~~~



Install the 'jack audio connection kit' which Dirt also needs:



~~~bash

brew install jack

~~~



*If Homebrew's installation of Jack fails with a `make` error, you can

 use the [JackOSX Installer](http://www.jackosx.com/download.html)

 instead. This will, however, add an additional step when installing

 Dirt (see below).*



### Alternative: Installing dependencies via Mac Ports



[MacPorts](https://www.macports.org/) is another package manager for

OS X.



If you already installed dependencies via homebrew, skip ahead to build Dirt.  

Otherwise if you happen to already use MacPorts, here's a list of

steps in order to get all dependencies:



~~~bash

sudo port install liblo libsndfile libsamplerate

~~~



Download and install jack2 [Jack Download Page](http://jackaudio.org/downloads/). Jack 2 has better OS X integration [Jack Comparison](https://github.com/jackaudio/jackaudio.github.com/wiki/Q_difference_jack1_jack2).



## Building Dirt from source



Get the source code for the Dirt synth:



~~~bash

cd ~

git clone --recursive https://github.com/tidalcycles/Dirt.git

~~~



Compile dirt:



~~~bash

cd ~/Dirt

make clean; make

~~~



If Dirt fails to compile after using the JackOSX installer as above,

 you may need to add flags to the Makefile to specify the appropriate

 paths:



~~~make

CFLAGS += -g -I/usr/local/include -Wall -O3 -std=gnu99 -DCHANNELS=2

LDFLAGS += -lm -L/usr/local/lib -llo -lsndfile -lsamplerate -ljack

~~~



### Homebrew users



As MacPorts installs all libs on `/opt/local/`

edit the Makefile to point the right direction of `libsndfile` and `libsamplerate`



~~~make

CFLAGS += -g -I/opt/local/include -Wall -O3 -std=gnu99

LDFLAGS += -lm -L/opt/local/lib  -llo -lsndfile -lsamplerate

~~~



## Starting Dirt under MacOS



To start Dirt, back in a terminal window, first start jack:



~~~bash

jackd -d coreaudio &

~~~



Or, if you downloaded Jack 2, then start the JackPilot at:

/Applications/Jack/JackPilot.app



Click __start__ button.



Then start dirt:



~~~bash

cd ~/Dirt

./dirt &

~~~



# Windows installation



## Cygwin



First, install [Cygwin](https://www.cygwin.com). In Cygwin, make sure the

following packages are installed:



~~~~

git

gcc-core

make

gcc-g++

libsndfile

libsndfile-devel

libsamplerate

libsamplerate-devel

~~~~



## Portaudio



Download Portaudio from http://www.portaudio.com. In Cygwin, Unpack

the download with `tar fxvz`. After unpacking, from Cygwin, go to the directory

where you unpacked Portaudio and then run:



~~~~bash

./configure && make && make install

~~~~



## Liblo



Download [Liblo](http://liblo.sourceforge.net).

In Cygwin, unpack Liblo with `tar fxvz`, then in Cygwin go to the directory where you

unpacked Liblo and then run:



~~~~bash

./configure && make && make install

~~~~



## Dirt



In Cygwin:



~~~~bash

git clone --recursive http://github.com/tidalcycles/Dirt.git

~~~~



Then:



~~~~bash

cd Dirt

make dirt-pa

~~~~



Then you get a `dirt-pa.exe` that works. Maybe this even works on any

windows system without having to compile. You'd need `cygwin1.dll` at

least though.
