Bleep Drum for PlatformIO

This is the code used in arduino in platformio : programming the bleep drum

Based on the original code from Bleep Labs : https://github.com/BleepLabs/Bleep-Drum

Build instruction

Using the Platformio Core CLI

Bleep Drum Samples

pio run -e bleep

Dam Drum samples

pio run -e dam

Dam Drum v2 samples

pio run -e dam2

Dam Drum v3 samples

pio run -e dam3

Program custom samples

0. Install the bleep tool with Python 3

I would suggest you create a virtual environment:

virtualenv venv --python=python3

To enter the virtual environment, just activate it:

. venv/bin/activate

Then install the bleep tool:

pip3 install .

If you plan on modifying the script, make this installation editable

pip3 install -e .

You can also make a symlink on OSX or Linux to make the bleep tool available anywhere on your system

ln -s ~/path/to/Bleep-Drum/venv/bin/bleep /usr/local/bin/bleep

1. Create YAML file to specify the source of the samples, let's call it samples.yml

firmware_size: 11658        # put firmware size without the samples here - this is used to warn you if you samples won't fit on flash
# sample_rate: 17000        # sample rate for resampling the WAV files - leave it commented to use the default

samples:
  tr808:                    # this is the name of the environment
    input_path: path/to/my/808
    samples:
      - file: 808-hat.wav   # 
        normalize: no       # don't normalize
        sr: 15000           # resample at 15kHz
        trim: 100           # trim the end by 100 samples
      - 808-tom.wav         # only the file name is required, just enter it as a string if you don't need to tweak other options
      - 808-snare.wav
      - 808-kick.wav

  tr909:                    # without specifying an input path, it will use the location of this file as a root directory
    - 909-clap.wav
    - file: 909-tom.wav
      trim: 134
    - 909-snare.wav
    - 909-kick.wav

2. Run the script :

bleep make samples.yml

This will generate all header files from the specified WAV files and update platformio.ini with the new custom environments.

3. Remind yourself of which environments are available

bleep list

4. Program your samples by specifying the environment name

bleep burn tr808

Bleep Drum Release notes

April 2020:
V15
Click track – Hold shift for 4 seconds to turn on and off click while the device is playing.
Clock rate stability – The sequence could slow down if too much was happening in the old version.
Better noise mode – Greater range of distorted sounds (hold shift while turning device on)
https://bleeplabs.com/2020/04/19/limited-quantity-of-bleep-drum-available-to-ship-now/

v12
http://bleeplabs.com/store/bleep-drum-midi/
Now compatible with current versions of MIDI, bounce and pgmspace.
It is no longer necessary to edit MIDI.h

Dam Drum sounds.txt contains the samples used in the second and third Dam Drum. All that was differnt in the Dam vs Bleep drums was the sounds. http://www.stonesthrow.com/news/2013/01/dam-drum

Here's a guide for getting your own sounds into the Bleep Drum. http://bleeplabs.com/2013/04/07/putting-your-own-samples-in-the-bleep-drum/
