Multi-Oscillator Detuning to Mimic Orchestral String Sound

String orchestra is one of the most developed forms of classical music, but the complicated layers and sounds of the instruments has posed a challenge for digital replication. This study aimed to mimic the sound of string orchestra in a digital audio workstation using detuned multi-oscillator waves. Propellerhead Reason 13’s Thor polysonic synthesizer was used as software to generate multiple layers of sawtooth waves. We chose the nn-xt String Orch sampler as the reference sound. Different detune amounts were measured and analyzed using frequency spectra in Audacity, then were compared with the reference string orchestra spectrum. A single sine oscillator wave produced a relatively uniform spectrum, while the multi-oscillator had greater spectral variations and a broader frequency distribution. Our study suggests that the multi-oscillator wave at a detune amount of 20 most accurately mimics the string orchestra sound, as detuning with an amount higher than 20 exhibited beating, instability in pitch, and harmonic imbalance, producing a more out-of-tune sound.
