NAME
mx44 - polyphonic, multichannel midi realtime software synthesizer
SYNOPSIS
mx44 [VOICES]
DESCRIPTION
The Mx44 is a polyphonic multichannel midi realtime software
synthesizer. It is written in C and hand optimized for the (Intel) MMX
instruction set. It runs under Linux, using any kernel modified for
realtime performance. The sourcecode is licensed under GPL.
The core algorithm is a 4 x 4 crossmodulating matrix (phase and
amplitude) with individual envelopes for each oscillator. Oscillators
have individual frequency intonation, can emphasize any of the eight
first harmonics and even do some internal crossmodulation. Envelopes
can be switched between VCA and VCF modes (ehrm, actually wawe-shaping,
but it will quack like a duck by any other name.) The sustainloop of
the envelope can be brought into oscillation in the audible spectre as
well as provide slow LFO sweeps. There is also a minor load of key and
velocity related modifications for wowie zowie realtime ecstacy
emulation.
It is very good for esoteric pads and ultra electric leads. I use it
all the time together with the Rosegarden sequencer or some of my old
Atari toys (like M!). I don’t think you can make it sound like a
realistic grand piano though, but then again: Somebody out there,
please prove me wrong. ;-)
A 166 Mhz Pentium will provide you with 20 simultanious voices, whereas
a 400 Mhz Pentium II can with ease provide you with 88 simultanious
voices. My current 1.1Ghz Celery occasionally runs 200 voices (800
oscillators). That ought to be enough for most people. Write any number
after the command to change the 48 voice default.
OPTIONS
VOICES Sets the maximum number of voices. Default is 48.
FILES
Mx44’s only data file is stored in /usr/share/mx44, and is copied to
$HOME/.mx44/ when the user launches the wrapper script. This allows
users to make changes to the patches.
SUGGESTIONS AND BUG REPORTS
Any bugs found should be reported to the upstream author and/or package
maintainer.
