Solenoise

midi to embedded system compressed file format converter for windows

Solenoise was a project I made over the summer of 2016 that could robotically play a piano using an Arduino mega and an array of 60 solenoids. Part of this project required a song to be stored on imbedded hardware, and to be playable by robot fingers.

This program converts:

• midi --> csv
• csv --> .h
• .h --> compressed .h

There is a batch script that performs all of these tasks and places each file that it creates in it's respective folder.

Convert all on Windows

1. Place music file to convert in folder titled midi/
2. Run MIDItoCompH.bat
3. When Prompted, enter name of midi file without .mid extension
4. File will be converted. Csv will reside in csv/. h file will be in H/. Compressed h file will be in compressed_h/.

midi to csv

midi to csv is done by the included midicsv.exe found here. This file is included in the source here so it does not need to be downloaded again.

csv to .h

To use: midiToH.py [csv file] [tracks to convert (-1 converts all tracks)]

Example: midiToH.py furelise.csv 2 3 4

Example: midiToH.py furelise.csv -1

The track numbers are imbedded into the midi/csv file and usually separate instruments. This feature is handy for removing drums or only selecting piano. Use -1 to select all the tracks. Other python files are outdated versions of the csv to .h converter.

.h to compressed .h

To use: compress.py [dot h file you want to convert]

The output file will be stored as the same file name with "_compressed.h" appended to it

Example: compress.py csv/furelise.h New file name would be furelise_compressed.h
