Drum Machine/sampler created with Java and C++. Originally a project for my off time, the goal is to eventually integrate this with input so a person can map audio input (i.e. beatboxing) to real samples, and quickly create loops or improvise during a show.

libsndfile, with C++ wrappers (version 1.0.17 or later)

rtaudio

java >= 1.6 (with JNI)

DRM-SEQ is a live drum sequencer/sampler capable of creating loops with small WAV samples. Any WAV file can be imported to the program. It has 8 "banks" capable of storing a unique instance of a loop.

This project was created with IntelliJ, and all the metadata is intended for that IDE.

1. Install the aforementioned libraries.

2. If the libraries are not in a default location on your system, establish the following environment variables:

   LDFLAGS: The search location for your libraries binaries.

   CFLAGS: The search location for C includes (in this case, JNI).

   CXXFLAGS: The search location for C++ includes.

Build this project using gradle:

Compilation:

gradle build

(if configuration fails, it is likely related to an error with the above)

Execution:

gradle jar

java -jar drm-seq.jar

Clean:

 gradle clean

The library helpers are located in libs/soundhelpers. To attempt to build only the helpers, you can run something like:

cd libs/soundhelpers && ./configure && make

This done by default in gradle build. To clean the helpers, run:

make clean

Create a row by selecting a sound in the file tree. Click any of the cells to play the sound at that point.

You have 8 banks, which you can populate with sounds. Click the bank you want to show. Select a bank for play by pressing the corresponding number key.

The click is universal, meaning that the position does not change when switching between banks. This is intentional, to make transitioning between loops easier.

For all banks, you control the following parameters:

For each row:
