Bedrock's MIDI Player is a free MIDI player created by BedrockSolid at around August 2014. This program's purpose was to test BedrockSolid's programming skills and to rely only on a MIDI synthesizer and is completely dependent on it and the modules used in the code. The 64-bit version can load 8 million notes in under 10 seconds.
It is very simple at the moment and there are almost no customizable options. However, it is still very useful and is a powerful MIDI player.
