So you think you can be the next EDM king! Here is a damn simple command line synthesizer for you.

WARNING: This is in very early stage.

You need Python 3 (tested on 3.7) with virtualenv. Also keep libaudio2-dev (or equivalent) installed.

1. Clone the repo:

   git clone https://github.com/grapheo12/clisynth.git

2. Spawn a virtualenv:

   cd clisynth
   virtualenv venv (or python3 -m virtualenv venv)
   source venv/bin/activate

3. Install dependencies:

   pip3 install -r requirements.txt

In the project directory, run:

python3 clisynth.py [SCALE] > [OUTPUTFILE].dat

where SCALE is a number from 1 to 7.

It opens up a synthesizer for you whose base note is C[SCALE]. For example, if SCALE is 4, then the base note is C4.

The notes you play will be output to OUTPUTFILE.dat file.

The keymappings are as follows:

a -> C
	w -> C#
s -> D
	e -> D#
d -> E
f -> F
	t -> F#
g -> G
	y -> G#
h -> A
	u -> A#
j -> B
k -> C'

space -> bass sound (set at G1)
any other key -> silence

The default duration for each note is fixed at 0.25s.

The generated OUTPUTFILE.dat can be compiled to a .wav file. Just run:

python compile.py [OUTPUTFILE].dat [SOUNDOUTPUTFILE].wav

If you like the effort, do consider contributing.

Hack the package as much as you want, raise issues and send PRs.
