Expanded Access Module

Here we have the Korg TR-Rack, the expanded rack-mount version of the groundbreaking Trinity.

This synth features 32Mb of samples in its ROM.  There are 415 multisamples and 458 drum samples, that make for a very eclectic, high-quality machine.  There are 512 Program patches, and 512 Performance patches.

Additionally, the effects section includes 100 types of insertion effects, and 14 types of master effects.

The sonic character of the TR-Rack is exquisitely pristine - the 24-bit samples really shine and sparkle, and there are so many categories of sounds that make this a very valuable module for many types of music.

The sound include some stupendous wave-sequence emulations, gorgeous pads, cutting organs, and some of the best drum kits I've ever encountered on a ROMpler.

Still a valid addition to any keyboardist's studio.


Korg TR-Rack factory demo song

Crazy DJ !!!  A very well-done song that encompasses several genres - you can hear how well the TR-Rack can tackle them.
