muse.eolas.com does not seem to exist; and there is no mention of muse anywhere on the pages of www.eolas.com. It appears the project has been abandoned. If anybody has older copies/pointers, upload them somewhere safe and add the links here, if the included license allows redistribution.

MDD Here's a download link to those old 2005 versions. [1]. Muse was renamed, to HueTunes, redesigned and ported to iOS a few years ago. Try it out at [2].

9-19-2005: Eolas releases Muse Hurricane Relief Edition

In the aftermath of Hurricane Katrina, Eolas has decided to donate 100% of all revenues it receives from the sale of Muse to hurricane relief. Please help them sell as many copies of this program as possible. You can buy Muse right now at http://muse.eolas.com The price is $39.95. Please buy a copy, and tell everyone you know to do so, too.

The full version of Muse adds exciting features to the free version including:

  1. the ability to create and play sets of multiple linked musart files
  2. tools for cloning objects
  3. the ability to do group operations on objects
  4. you can create musart that uses any 16 instruments from a set of 128 possibilities
  5. many improvements to the gui

MDD The free version of Muse has been updated to employ the same GUI as the full version, and it can play multi-image linked musart created by the full version.

Muse 1.0 is a Tcl-based game that combines drawing with music authoring. The Web site is http://www.eolas.com/muse/ To download the Starkit or Starpacks for Win, Linux and OSX: [3] Muse uses the terrific Muzic cross-platform MIDI sound package, developed by Steve Landers

Once you're running Muse, you can try out the above musart file by downloading http://www.eolas.com/muse/examples/Freight-Train2.muz and loading it into Muse. You've really got to see/hear this one. It's pretty amazing.

Other sample musart can be downloaded at [4]

Developed by Eolas

9-19-2005: Muze re-renamed back to Muse

8-16-2005: Muse has been renamed to Muze, to avoid confusion with a well-known Linux midi application. There are new beta versions available at http://www.mymuze.com

Also, GREAT NEWS! Muze now runs on Windows, OSX, and Linux. You can download both a cross-platform Starkit, or Starpack binaries for the various platforms. There are many many new features. Take a look at the help menu to see the details.

7-6-2005: New version (b5) posted today -- see below.

6-29-2005: Eolas Muse v. 2.0(demo) is being released today to the Tcl world for beta-testing. It was developed by Mike Doyle (MDD), Cyndy Lilagan and Maury Pescitelli of Eolas. We'd like to invite members of the Tcl Community to help out with the beta test, by beating on it a bit and letting us know what you think. At least for now, Muse is only available for the Windows platform.

You can download the Windows Starkit at http://www.eolas.com/muse/muse-2b5.kit (if you already have tclkit), or the Starpack at http://www.eolas.com/muse/muse-2b5.exe (or [5]) for a self-contained single-file executable. There are also some example Muse art (musart) files available for download: [6] [7] [8] [9] [10] (they don't sound like much, but they do demonstrate Muse in action). Please post to this wiki page any cool musart files that you create with Muse.

This is free-but-not-open-source software, so please don't be put off by the fact that the main source file is bytecode compiled. We're doing it this way because we're expecting to have an enhanced commercial version available for sale sometime mid-summer 2005.

LV What are the software requirements besides downloading the two files above? MDD: First of all, you don't need both files above, just either the Starkit or the Starpack (depending on whether you've already got tclkit installed). As far as hardware requirements go, you'll need a Windows PC with a MIDI-capable sound card. That's it, as far as I know.

About Eolas Muse

Eolas Muse is the first example of an addictive new category of personal entertainment software that merges the best features of interactive graphics with an exciting new approach to music authoring. With Muse, you create art that is both active and interactive and, while you're at it, you'll find that you're creating music that is both visual and dynamic.


Originally inspired by a museum exhibit at the Exploratorium, in San Francisco, Muse version 1.0 was developed by Cheong Ang and Mike Doyle, of Eolas Technologies Inc., in 1994-1995. This version, while extremely limited in functionality, entranced virtually everyone who saw it. In fact, that's why we named it Muse.

Muse 2.0 was developed by Eolas' Mike Doyle, Cyndy Lilagan and Maury Pescitelli, in 2005, with technical assistance from Steve Landers. Muse 2.0 added much to the original Muse concept, and now pushes the envelope in merging the fields of art and music in new and innovative ways.

Muse 2.0 was a complete rewrite, inspired in concept by Muse 1.0, but built from the ground up using Starkit technology.

Getting Started

All you have to do to get started creating your own exciting Muse artwork is to select a working color, by clicking on one of the keys of the onscreen piano keyboard, then select the drawing tool that you'd like to use. Then just drag your mouse on the canvas while holding down the left mouse button to draw an object. Each color on the keyboard is associated with a different musical note.

You'll notice four colored trackers, small dots, moving across the screen. When any of these trackers crosses a color that you've drawn, Muse plays the musical note associated with that color.

There is much much more to the functionality in Muse. Just click on the Help menu option to see the complete instructions for use.


Eolas Muse 2.0 makes use of some pieces of code contributed to the Tclers' Wiki by Tcl luminary, Richard Suchenwirth. These pieces include Richard's A tiny drawing program and A toy piano. Also, some code was used from Maurice Ulis' Serializing a canvas widget. Finally, the Help system is provided by jcw's Wikit package. The Muse authors would like to thank these creative Tclers for their always-interesting OSS contributions to the Tcl Community.

We would like to give special thanks to Jean-Claude Wippler and Steve Landers, et al., for bringing the Tcl Starkit technology into being. It really is the best thing (for software development, at least) since sliced bread.

RS: Drawing works well here on my old W95 box, but I hear no sound. In contrast, TclMusic works and sounds as usual. MDD: I've noticed the same problem on my daughter's 6-year-old PC. I'm not sure what the problem is, other than the feeling that it must reside in the midilib dll. RS: On a more recent XP box box at work, sounds come too - a truly fascinating plaything. Just that I have to concentrate on work here... MDD: That's great! You just made my day.

RLH: Works fine on WinXP. I was wondering, on a real piano you can run you finger from one side of the keyboard to another, Muse doesn't let you do that. Maybe it wasn't meant too? MDD: If you draw the scales on the canvas, you can do that by then passing the mouse cursor back and forth over the drawing

PWQ '2 Jul 05 Feedback on Muse 2.0, Tested on Windows2000 Server. The user was surprised or confused by the fact that:

  1. They could not delete a 'blank' note (black chord). You first have to change it's colour.
  2. The tracker would skip notes that are placed close together on the track.
  3. That the animation of the tracker dot was not in the colour of the note being played.
  4. The error message that y0 did not exist when attempting to create polygons sometimes.
  5. Accidently creating very thin rectangle that could not be filled or deleted.
  6. Sometimes tracks do not respect the F1/F2 to hide or show.
  7. That F10/F9 do not show the default tracks.
  8. The speed of the tracker dot could not be changed by the way the track was drawn (ie fast or slow), or apparantly by any other means.
  9. They could not move the track points once drawn.

MDD: Thanks for the comments. First of all, there's a new rev (b5) you should download. Regarding the specific comments: 1) At least for now, that's a feature, not a bug, 2) If you draw a path quickly, it spreads the path points apart and you can therefore possibly skip over colors. A solution is to use the "Point" tool, 3) Nice catch! It's fixed now., 4) We're having trouble reproducing that problem, can you remember what sequence of actions caused it?, 5) We're working on this one, 6) No one else seems to be encountering this, and we can't reproduce it, 7) ditto, we can't reproduce this one either. One problem we have noticed, though, is that F10 freezes the window until you click anywhere in the window, which unfreezes it again. Not sure why that's happening., 8) and 9) No one else is encountering this problem, that we know of. It works fine on the 20+ systems we've tested it on. Some other new features in the latest revision include 1) saving the state of the default trackers (on or off) when you save a file, so that, if you save while trackers are turned off via F10, then they'll stay off next time you launch the image, and 2) argv processing, so you can now associate musart (.msc) files with muse-2b5.exe, and just double click the musart files to launch them in Muse.

DKF: I also see problems with F9/F10 intermittently. Seems to be some kind of focus problem.

[ANON]: Select "About Muse" in the menu, display claims several patents on it. The authors took what other tclers contributed and now try to patent as their own. Nice.

MDD: Those patents have nothing to do with "what other tclers contributed." In fact, one of them even pre-dates Tcl, itself. Smearing someone without even having the cajones to use your real name. Nice.

[ANON]: Eolas has contributed to the TCL open source. Therein lies a minefield of problems. Assume I use some tcl code for my own commerical application, which is fair under the GPL/BSD, some day I wake up to find some entity such as Eolas deciding to sue me because the code has a software patent. That is the issue. They expouse supporting open source while at the same time active in software patents. Just because they are "acting nice" by only suing MS and no one else is not a reliable solution that anyone can count on. I for one now have to think twice about using tcl for a commercial platform. I sincerely believe because of Eolas' actions (MS suit), tcl has suffered as a development platform.

SRIV I use Tcl for commercial apps, and use/distribute GPL Tcl code. If you knew what you were talking about, you'd know that the Eolas/MS suit has nothing to do with Tcl or the use of GPL/BSD licensed Tcl code.
