![Virtual Instrument : MOTU debuts MX4 virtual instrument plug-in for MAS, AU and RTAS - macmusic](http://inc3.440net.net/img/index.php/q/2KOdW7CsYG-0h-fb0JSarUh07Z-ooaVDo56drNnb4NDZgKKaiabv2ODMjVyoc1hznM7bi6aUb21gW6uVrpuNXLI)
AES: MOTU is demonstrating MX4 ($295), a new virtual instrument plug-in for MOTU DP4 (MAS), Pro Tools (RTAS) and other Mac OS X audio hosts (Audio Units). MX4 features a unique, hybrid synthesis engine that combines several forms of synthesis, including subtractive, wavetable, frequency modulation (FM), amplitude modulation (AM) and analog emulation. MX4's flexible programming and advanced modulation architecture provide the intimacy of a vintage synth, the flexibility of a modular synth, and the innovation of a virtual synth.
As a plug-in, MX4 operates efficiently and provides unlimited voices, polyphony and instantiations (subject to the processing resources of the host computer). Playback is sample-accurate with supporting host applications, such as Digital Performer 4. MX4's 32-bit internal resolution provides wide dynamic range, and it supports all standard sample rates up to 192kHz. Users can work fast and intuitively in a single, efficiently organized window labeled with real-world values like semitones, decibels, etc. All settings are saved with host software projects for instant recall.
MX4's basic synthesis architecture provides 3 oscillators with modulatable waveform symmetry and hard sync, 2 variable topology multimode filters, 4 variable waveshape LFO's and 4 ADSHR envelopes.
