Mouse of a Time
Back in the late 1980s
a certain Laurie Spiegel coded a new type of music software
called Music Mouse that turned your computer into a
musical instrument. It created quite a stir in the computer
music world in that it allowed non-musicians as well
as accomplished ones to make music just by moving the
mouse. At the time it was called "algorithmic music",
"interactive software" and "expert system".
These types of programs were just beginning to get under
way and now (2002) are seeing a new interest.
Originally coded for
the Mac in 1985, Music Mouse was ported to the ST platform
in 1988 with the help of David Silver. Basically it
takes mouse movements inside a grid on the screen and
transforms them into four moving voices that can be
assigned different MIDI channels and sounds, depending
on what you do on the QWERTY keyboard. Other QWERTY
keys are live in real time as controller faders and
for playing with tempo, transposition, and a host of
other features. Musicians as well asnon-musicians can
benefit from this simple-to-use yet deep program. Laurie
is continuing to upgrade it for the Mac platform, but
the Atari version is still pretty much identical to
the current Mac revision.

Application In order to record Music Mouse
you need an external sequencer, either hardware (such
as a stand-alone or the sequencer built into synth workstations)
or another computer running sequencer software (another
Atari, PC or Mac). An alternative is to record live
directly to tape, or whatever medium you use to record.
In my own applications,
I run Music Mouse on my 1040STE or Falcon and record
directly into Cubase on my TT030 (it also works on the
TT030 with the cache off). I can run several tracks
of Music Mouse material, then add percussion and other
parts as the piece needs. To synchronize the music,
I use the Match Quantise tool in Cubase to match Music
Mouse tracks to other tracks. Another trick to get more
scales is to use the Input Transform option and transform
Music Mouse in real time to any of the selection of
scales available in the Input Transform window. Dr T's
Omega II also has an option to map notes to other notes
or scales, so the same thing can be applied. I have
also tried running Music Mouse through the Hotz Translator
software, giving me 128 more scales.
I also use different
MIDI channels for each voice. For Example: one voice
is assigned a marimba sound, another an acoustic guitar,
while the remaining voices I assign a sustaining type
sound such as strings or a pad sound. Of course, anything
can be changed at any time while you play. Another application
is to record rhythmic patterns into Cubase at a tempo
of 90 or 100. Then record another track in Cubase using
MM as a melody or lead instrument (using a single voice)
with the tempo at 300 to produce fast "licks".
Using this technique in combination with pitch bending
(using the wheel on your regular MIDI keyboard) you
can play some wild Jan Hammer style licks! Sometimes
I assign MM to MIDI channel 10 to produce percussion
tracks, which can be a lot of fun. Hitting the [A] key
starts MM in auto-compose mode, where you can change
the textures by moving the mouse and changing the pattern
with the number and function keys.
Techniques It takes a little practice
to move the mouse to produce the results you want. My
technique is to use small circular motions in one area
of the grid, then move all four voices slowly up or
to the side or downward. Sometimes I leave three voices
at the bottom of the grid slowly moving back and forth,
while moving the horizontal axis upwards to produce
a melody. Another trick is to start with one voice,
then slowly add voices (un-muting them with the numeric
keys). Yet another trick is to put MM in the Octatonic
mode, use only one voice each on the horizontal and
vertical axes, with a tempo of 120. Then start doing
circular motions starting at the bottom of the grid
and expanding upwards. Instant ELP (Emerson, Lake and
Palmer) style! Sometimes I move the mouse slowly to
produce chords at certain parts of the grid. Hit the
space bar to silence the mouse, and then move the mouse
to another part of the grid, then hit the space bar
again and another chord is produced.
Hitting the [Help] key
brings up the menu. In this mode, you can select individual
MIDI channels for each voice, select MIDI Thru, and
also MIDI Output selection for patch change which include
General MIDI, Casio CZ-101 and the Ensoniq Mirage. With
these selections, you sure can tell what era the program
was coded in! However if you have these instruments
(and they are quite cheap now) you are in luck!
Availability Laurie still has some copies
of the Atari version left. If you are interested they
cost $29.00 (including US shipping). For international
orders add US$6 for postage. You can order it from the
link below. Show your support. This edition comes with
an excellent manual as well.
Which Mouse? Even though there are many alternate
mouse controllers available for the Atari platform (MIDI
Joy, Quaderno, MIDI-Mouse Music, MousMuso, to name a
few) I keep coming back to the original and only Music
Mouse. It packs a lot of power in a 40 KB program! The
ease and depth of Music Mouse keeps me coming back for
more. I find it invaluable for any musician as well
as anyone using an Atari for MIDI. All you need is an
Atari and a simple MIDI module to make music only Music
Mouse can produce.
To listen to what Laurie
has been doing in her own compositions with Music Mouse,
check out her CD called, "Unseen Worlds."
Information on her home page as well as sound clips
on the Kalvos Damian Composer Page. Her own home page
is also worth exploring with many fascinating topics,
including a section on her most recent work, "Obsolete
Systems" which explores her past encounters with
electronic and experimental music.
