POCKETROCKIT - A rocket in your pocket that rocks!

Project page

Write a music track and play it while you write it. As you might know it from Sonic Pi, but in Python (sonic.py was not available on PyPi, though).

Usage

Workflow is not quite mature yet, so here is the short version for now.

Create and enter a development folder and provide required SoundFont files (configurable later, hard-coded for now)

mkdir mytracks
cd mytracks
cp /usr/share/soundfonts/FluidR3_GM.sf2 .

Download Roland JV-1080 Drums (JV_1080_Drums.sf2) to that directory.

Create a file myfirsttrack.py with the following content:

#!/usr/bin/env python3

from pocketrockit.decorated import Env, midiseq, player, track

@track
def po20(env: Env):
    """A Pocket Operator PO-20 Arcade (well, not yet)"""

    env.bpm = 60
    key = "C3"

    @player
    def melody():
        yield from midiseq(
            " t6  t5  t6  t3 "
            " t1  t3  t0  .  "
            " .   .   .   .  "
            " .   .   .   .  ",
            key=key,
            channel=25,
        )

    @player
    def drums1():
        yield from midiseq(
            "x .  x  . "
            "x .  .  . "
            "x .  x  . "
            "x .  x  x ",
            channel=128,
            note=33,
        )

Now - keeping the editor open for later use - execute this file. You can either make it executable and run it directly or you run python3 instead:

chmod +x myfirsttrack.py
./myfirsttrack.py

# or

python3 myfirsttrack.py

Installation

[<PYTHON> -m] pip[3] install [-U] pocketrockit
