Built-in convolution reverb allows users to place their ensemble in authentic acoustic spaces, from orchestra sound stages to renowned concert halls to majestic cathedrals. Easy to use controls let users further adjust each instrument to achieve the perfect sound. Sounds can also be directly loaded into MOTU's MachFive sampler plug-in for more advanced layering and programming.

The MOTU Symphonic Instrument provides 16-part multi-timbral operation via the part list on the left-hand side of the window. Users choose the desired instrument for each part and assign a MIDI channel. To layer two or more instruments so that they play the same notes, users simply assign the parts to the same MIDI channel. Instruments to be played separately are assigned a unique MIDI channel. The controls to the right of the part list allow users to adjust the sound of the currently selected instrument, including ADSR amplitude envelope controls, an LFO, two filters, tone controls, pitch controls and velocity response. Global parameters, such as maximum allowed polyphony and global volume/pan, are displayed across the top of the window. Finally, the bottom portion of the window displays controls for the convolution reverb, including a menu for choosing the desired acoustic space and seven knobs for further adjusting the sound of the space. The MOTU Symphonic instrument is driven by the 32-bit UVI engine.

Convolution is a process where the characteristics of a real acoustic space are "sampled" (captured) and then faithfully reproduced, down to the last detail and nuance. Users can choose from a wide variety of acoustic spaces included with the MOTU Symphonic instrument to greatly enhance the realism of their orchestral recordings. Highlights include ensemble chambers, concert halls and soaring cathedrals.
