IK Multimedia ReSing Choir

IK Multimedia introduces ReSing Choir, the first standalone vocal production software that transforms a single vocal recording into a rich, expressive choir of up to 5 different modeled voices per song section. A worldwide premiere in music software, ReSing Choir delivers a full vocal lineup without needing a room full of singers. For the first time, anybody working with music software, from producers to songwriters to audio engineers, can create backing vocals, doubles and multi-part harmonies with distinct singer identities and editable parts, anywhere - from professional studios to bedroom setups.

ReSing Choir brings ReSing's groundbreaking voice modeling into a standalone application that runs separately from ReSing, combining the distinctive timbre, tone and expression of real artists with chord-aware automatic harmonization, Auto-character technology and detailed melodic and performance editing. Producers can combine distinctive voices, build lush harmonies and sculpt expressive vocal parts in one dedicated workspace, without the overhead of multiple plug-in instances or cloud credits. IK's professional singer models are created with the full participation, consent and fair compensation of the original artists.

ReSing Choir at a Glance:

• Vocal ensembles: Transform a single vocal recording into a choir of up to 5 modeled singers per song section.
• Includes 10 Voice Models: A selection of high-quality models from the full version of ReSing.
• Automatic harmonization: Generate vocal harmonies that follow your chord progression.
• Personalized vocal lineup: Combine singers from the ReSing library with custom voice models, including models of your own voice.
• Flexible part assignment: Assign each singer to Source, Unison or Harmony parts above or below the melody (±1, ±2 or ±3).
• Auto-character: Bring greater expression and natural variation to vocal performances with new Auto-character technology.
• Ensemble shaping: Adjust timing, pronunciation variation and pitch spread, then position your singers in the mix with panning and reverb.
  Pitch and expression editing: Fine-tune individual notes, vibrato and transitions in a unified, color-coded piano roll, with locked notes preserved when reharmonizing.
• Section-based arrangements: Create distinct vocal arrangements for different song sections and duplicate setups to explore variations.
• Offline processing and export: Process vocals entirely offline, with no cloud credits or usage quotas, and export a mixdown or individual dry vocal stems.

Each modeled singer can follow the original pitch movement, perform an editable Unison part or take a Harmony above or below the melody. Producers can explore new vocal combinations without rebuilding the arrangement: replacing a singer retains part assignments, mix settings and manual note edits. The original vocal and optional instrumental reference keep the ensemble in the context of the track.

ReSing Choir's automatic harmonization follows the producer's chord progression, with the Harmonize control balancing the relationship between the source melody and chord tones. The arrangement remains fully editable in Unison and Harmony parts, giving producers room to develop flowing counter-melodies, expressive vocal responses and distinctive harmonic ideas. Individual notes and phrases can be shaped in a color-coded piano roll, with locked edits preserved during reharmonization. Vibrato and transition controls add expressive detail within notes and between phrases.

Auto-character technology varies the selected vocal character throughout a performance for a more dynamic, natural and expressive delivery. Timing shifts rhythmic placement ahead of or behind the original performance, variation introduces organic micro-timing variations to word and phoneme onsets, and detune adds small pitch differences between singers. Together, these controls shape the lively interplay of individual performances, while independent panning and integrated reverb spread the voices across the stereo field and bring them into a shared acoustic space.

Up to 10 independent sections per project let producers build contrast between intimate verses, lush choruses and distinctive bridges. Each section has its own vocal source, singer combination, arrangement and instrumental reference, with duplication allowing producers to reuse setups and explore alternatives. Sections export separately as a full mixdown, individual dry processed vocal stems or both. Mixdowns retain balance, panning and reverb, while stems offer flexibility for further mixing in a DAW.

ReSing Choir is available now and registered ReSing full and MAX users can get ReSing Choir at a special upgrade price. New users can get ReSing Choir at a limited-time introductory price as a perpetual license through the IK Multimedia online store and authorized dealers worldwide, with no recurring subscription fees.

ReSing Choir can be expanded with any ReSing singer models that customers already own or purchase separately from the over 66 voice models now available in the ReSing library and collections in English, Spanish, Japanese and Portuguese, or with models they create with ReSing Modeler.
