# SamplerBox
*Update: [Remove drums from song](https://www.yellownoiseaudio.com) with the VST DrumExtract!*
SamplerBox is an **open-source DIY audio sampler project** based on RaspberryPi.
Website: [www.samplerbox.org](https://www.samplerbox.org)

# Install
SamplerBox works with the RaspberryPi's built-in soundcard, but it is recommended to use a USB DAC (PCM2704 USB DAC for less than 10€ on eBay is fine) for better sound quality.
You can use a ready-to-use ISO image from the [Releases](https://github.com/josephernest/SamplerBox/releases) page or do a manual install:
0. Start with a standard RaspiOS intsall. The following steps have been tested with [2021-05-07-raspios-buster-armhf-lite.zip](https://downloads.raspberrypi.org/raspios_lite_armhf/images/raspios_lite_armhf-2021-05-28/2021-05-07-raspios-buster-armhf-lite.zip).
1. Install the required dependencies (Python-related packages and audio libraries - the current version requires at least Python 3.7):
~~~
sudo apt update
sudo apt -y install git python3-pip python3-smbus python3-numpy libportaudio2
sudo apt -y install raspberrypi-kernel # quite long to install, do it only if necessary, it solves a "no sound before 25 second on boot" problem
sudo pip3 install cython rtmidi-python cffi sounddevice pyserial
~~~
2. Download SamplerBox and build it with:
~~~
git clone https://github.com/josephernest/SamplerBox.git
cd SamplerBox
sudo python3 setup.py build_ext --inplace
~~~
3. Reboot the Pi, and run the soft with:
~~~
sudo python3 samplerbox.py
~~~
Play some notes on the connected MIDI keyboard, you'll hear some sound!
4. *(Optional)* Modify `config.py` if you want to change root directory for sample-sets, default soundcard, etc.
# How to use it
See the [FAQ](https://www.samplerbox.org/faq) on https://www.samplerbox.org.
# Notes
A few remarks:
* the current version works on Pi 2, 3, 4 (re-tested on Pi2 & Pi4 on 2022-08-09)
* the current version also works on Windows if all the required modules are installed
* MIDI via GPIO/serial should be re-tested with the current version, see https://github.com/josephernest/SamplerBox/issues/49
* 7-segment display confirmed working as of 2022-08-09, see [requirement](https://github.com/josephernest/SamplerBox/blob/916ae0a5504b0ce757d89e2ece4c65efb60b6d91/samplerbox.py#L361)
# ISO image
The ready-to-use ISO images available on [www.samplerbox.org](https://www.samplerbox.org) are built with the help of a script that can be found in `isoimage/maker.sh`.
