It was Korg's first modern workstation and marked a significant evolution from its predecessors by offering features such as built-in digital audio recording, 32-note polyphony, an extensive internal sound library, assignable effects, and a large touchscreen for advanced control and editing functions, a feature not previously seen on any musical instrument.

The Trinity boasted the ACCESS sound generator, which included 48 MB of PCM waveforms and introduced resonant filters into Korg's workstation lineup for the first time.

[1] The Trinity utilizes a large, touch-sensitive screen for editing, allowing users to select parameter names or icons and modify values using the data entry fader, up/down buttons, the 10-key keypad, or the spinwheel.

The Trinity Plus ($3,999/£2,700 MSRP) included the "Solo Synthesizer" board, incorporating the sound engine of the Korg Prophecy for integration into the workstation.

An SCSI-TRI option (redundant if HDR-TRI installed) ($599/£399 MSRP) added SCSI interfacing to external high-speed mass-storage like hard and/or optical drives.

The SOLO-TRI "Solo DSP Synthesizer" (monophonic) option ($599/£475 MSRP) compatible with Korg Prophecy soundpatches (included factory installed in "Plus"/"Pro"/"ProX" models) was also available separately for the base Trinity.

[4] A Trinity version 1 or 2 operating system is required to utilize an installed SOLO-TRI board and enable access to Program "Bank S" containing Solo DSP Synthesizer soundpatches.

Later (replacing the SOLO-TRI on the market), the MOSS-TRI "MOSS DSP Synthesizer" (6-polyphony) option compatible with Korg Z1 soundpatches (included factory installed in "V3" models) was available separately.

A Trinity version 3 operating system is required to utilize an installed MOSS-TRI board and enable access to Program "Bank M" containing MOSS DSP Synthesizer soundpatches.
