I started playing around using the melody and chord progression that a huge number of people created together at CrowdSound, and ended up making this little arrangement for Bawami, my MIDI synth. It took a few hours over 3 nights.
CrowdSound is a site where people were given a chord progression and song structure, and were then allowed to vote note-by-note to make a melody. It’s an experiment to see if lots of people can work together to gradually make an entire song by voting on many tiny additions. Since people are making remixes already, I decided I’d try, too.
As of the 15th of August 2016, only the melody is complete, so I imported the MIDI of the melody (from here) into Sekaiju (the MIDI editor I use). From there, based on the chord progression, I made tracks for bass, percussion, overdriven and acoustic guitar parts, 2-part pad and a portamento synth sequence to liven things up a bit. Then I decided on how I’d switch between the various backing parts so they weren’t all fighting for the spotlight at the same time. After that, I changed the velocities of all the melody notes (since I’m using a velocity-sensitive lead instrument on Bawami), to make it sound less annoying and repetitive and to complement the beat. I also shortened some long notes (which is within CrowdSound’s rules for arranging) to let the lead stop for breath every now and then, added modulation (vibrato) sparingly, and decided to somtimes pitch-bend from one note to another during the conclusion instead of instantly jumping (I think this should be allowed, because a real human voice would have to do this all the time =P).
In keeping with the openness of CrowdSound, you can download my MIDI (designed to be played on Bawami rev.132 or later) here. It uses several GS “variation” instruments, so it will sound worse on GM synths. It also uses an instrument (12-string Guitar) which is not present in Bawami rev.131, the currently-released version, but it should still sound fine on that version (it’ll fall back to the “Acoustic Guitar (Steel)” instrument). That, along with many other changes, will be in the next version I release!
This MIDI is playing on BaWaMI, which is a freeware, retro-sounding MIDI synth that uses subtractive synthesis. I’ve been working on it every now and then since 2010. You can find out more (and grab the latest version) here (click its title to get to the download page).
The 3D scrolling view of notes is MIDITrail.
Here’s my MIDI software synth Bawami doing its best to even keep responding while trying to play TheSuperMarioBros2‘s black MIDI “Arecibo“. The left view shows how it’s processing every MIDI message. Not shown: About 5 minutes of Bawami loading the 12MB MIDI file hideously inefficiently (tempo changes make it even worse).
This problem of my player stopping responding when maxed out is something I need to (re-)fix. I fixed this a long time ago (probably before releasing Bawami), but broke it again afterwards somehow, also a long time ago now… As always, the most recent version of Bawami can be download here (also check the most recently tagged posts to see recent changes).
TheSuperMarioBros2 have made a lot of great black MIDIs that are often fun to stress-test MIDI players with. You can see lots playing at their channel (they also provide download links for the MIDI files). However, Bawami’s loading of MIDIs is inefficient, so I’d recommend not trying to torture it with black MIDIs too much. I also suggest unticking “Loop” so that, if it stops responding during playback, it’ll eventually start responding again at the end.
This is a small update which fixes OGG file rendering, and a couple of other superficial things.
- Fixed tabbing order of controls on “Mod shape” tab of the config window.
- Writing OGG files works again – I accidentally removed a file needed by the OGG encoder in revision 130. Users who extracted revision 130′s folder over revision 129′s would not have experienced the problem.
- Stopped warning about buggy controls from being displayed on the “MIDI params” tab of the config window, since it’s no longer true.
This update lets Bawami write WAV files in paths containing non-ASCII characters (something long-overdue), and fixes a bunch of complicated interwoven bugs related to the handling of “bad” MIDI files and of percussive notes. There’s also a load of other fixes, including for portamento-related bugs, crashing in /translator mode, and visual fixes, and a couple of new instruments.

This is a nice big bunch of fixes – mostly related to /console-mode, but a couple of more serious things (which affect more people) are fixed, too.
You can grab this latest version from here (7.87 MB), and see details of all the changes below.
General bug fixes
- Fixed bug where button to browse for a new MIDI file remained disabled after opening a MIDI by dropping it onto the main window.
- Now recognises when a filename is passed on the command line without speech marks (and without any command line parameters). This fixes the problem of Bawami not opening a path+file containing no spaces if such a file was dragged onto its icon (or if Bawami is associated with .MID files), because Windows does not automatically surround such a path+file with speech marks when passing it to the program.
Fixes for when using /console
- No longer crashes if you’re redirecting Bawami’s output to a file or other program.
- When using “/infolevel 2“, log file text is now sent to StdOut instead of (accidentally) to StdErr.
- “Finished.” is now (always) displayed when shutting down.
- Key prompts for answers to questions are now sent to StdErr instead of StdOut (as was already being done for the question’s title and message), so that they’re visible on the console even if you’re redirecting Bawami’s StdOut to a file.
- Green “settings” button’s tooltip is now loaded in the chosen language (instead of having no tooltip) (broken in revision 128).
- Corrected Z-order of several controls on the config window so that the dotted border that indicates a control that has focus isn’t having one of its horizontal edges cut off unnecessarily.
- Corrected a reference to how green “settings” button appears in info.txt.
Logging (also affects text shown when using /console /infolevel >=1)
- No longer shows “Closing MIDI input port” when shutting down, if MIDI-in wasn’t in use.
- No longer shows “Decoding absolute timings” a few lines after the last track has finished being decoded.
This version includes a whole load more bug fixes, plus some serious support for running Bawami from the console (command prompt), which also guarantees to never display message boxes, along with several other fun new command line parameters. It should also start slightly faster (less writing to log file, and some language files are now only loaded when they’re needed), seeking to a different playback position is easier on the ears, and there’s a bunch of safeguards added to the code related to writing OGG files. A few command line parameters have been renamed to make them less long-winded, they all begin with a slash instead of a hyphen now, and Bawami now lets you know exactly which ones it didn’t understand (if any). But despite a lot of work being focussed on command line parameters, there are several GUI-related bug fixes, too!
NOTE: In order for Bawami to be able to output to the Windows console (command prompt) when using /console option, the EXE file is now compiled as a console-mode program. Annoyingly, this causes a console window to appear for a brief moment before Bawami’s main window appears. However, this doesn’t slow anything down; it’s only for part of the amount of time where, previously, nothing at all was displayed.
You can download the new version here (7.87 MB). Full details on all of the changes and bug fixes are below, but allow me to first introduce a new feature of Bawami:
If you run Bawami from the command line, this option should be very useful, and is highly recommended instead of /invisible. Text is output to “standard output” (meaning you can see what Bawami’s doing in the console), and you can respond to any messages by pressing keys on the console, too. In this mode, Bawami also starts faster and is safe to crash in the middle of playback (nothing is leaked – but for now, make sure that you also kill the OGG encoder if you crash it in the middle of writing an OGG file). Just for fun, you can also view every single raw MIDI message scrolling up in the console as it plays (/stdmidi) , and use /infolevel 1 or 2 to get a more in-depth look at exactly what’s going on internally. Of course, these options which spam text to the console will slow Bawami down a bit. Please check the “COMMAND LINE PARAMETERS” section in info.txt for full details, and see below for an overview of all changes/additions.

When I first published revision 127 of Bawami about 25 minutes ago, the download included a 64-bit version of “vcut.exe” (official Vorbis splitter, used by this version of Bawami) which would not work on 32-bit Windows. A universally-compatible, 32-bit version is now included instead.
To avoid problems (OGG file export not working), I highly advise that you re-download it if you downloaded it within the past 25 minutes. I am sorry for the inconvenience.
This is essentially a whole bunch of bug fixes, including one that I really should’ve released sooner (no longer freezes at the end of exporting a WAV/OGG file under certain conditions). There aren’t really new features, which should mean that, for once, the total number of bugs has actually decreased! ^^;
Most fixes are regarding WAV/OGG file-writing, click artifacts due to release times, and a couple of visual glitches. Full details are below the page-break.
EDIT: When I first published this post, the download included a 64-bit version of “vcut.exe” (official Vorbis splitter, used by this version of Bawami) which would not work on 32-bit Windows. A universally-compatible, 32-bit version is now included instead. Sorry for the inconvenience.
This release fixes the bug where, if pan changed on a MIDI channel playing more than one note, only the panning of one note would change (bug added in revision 122). I only just noticed this, and it annoyed me a lot, so I’m releasing this version with only this change.
