MOTU Now Shipping MX4 Virtual Instrument


August 10, 2004

The MX4 is MOTU's hybrid synthesis virtual instrument, which is
now shipping for Digital Performer (MAS), Pro Tools (RTAS), Logic Pro and
other Mac OS X audio hosts (Audio Units). The release includes several additional
features not previously announced, such as built-in effects, more LFOs, external
audio input, a unison multiplier and parameter randomization options for creative

Built-in chorus and delay effects allow users to program, save and recall
patches with these effects as part of the patch. The effects section can be
independently shown or hidden to conserve screen space.

Six LFOs can independently modulate any of MX4's continuously variable parameters.
LFO waveshapes include sine, sawtooth, rectangle, sample & hold, sample & ramp
and random walk. LFO controls include rate, fade, delay, phase, and symmetry.
In addition to a range from 0-360 degrees, phase can be triggered randomly.
Users can also choose a setting called 'Free Running', which allows the LFO
to run completely independently of any notes being played. For example, users
can apply a filter cutoff sweep over several measures, regardless of the notes
being played.

Any external audio input can be fed into MX4 via a mono or stereo sidechain
bus, where it is then blended with MX4's audio signal before the two filters,
amplitude envelope (for note triggering) and effects.

The 'unison multiplier' allows users to fatten MX4's sound by multiplying
the number of notes played each time a key is struck. For example, if the multiplier
is set to 3, each time a note is played, three notes sound. Combined with MX4's
adjustable detune feature, users can quickly create rich and lush sounds.

When users click the 'Random' button, the MX4 window flips to the plug-in's
rear panel, complete with serial number plate and ventilation grill. There,
users can independently randomize various combinations of parameters to instantly
create new patches. By constraining what is randomized, users can quickly zero
in on the most interesting and productive results.

MX4 is now available for a suggested retail price of $295.
