The output of the second oscillator in the Modular Synth Component seems a bit buggy to me. It seems like most waveform Types, especially when combined with Octave transpositions, generally “don’t work.” For instance, mixing a Sine in Osc1 with a Sine in Osc2 an octave down makes it sounds more like a distorted sawtooth than a fundamental and a first harmonic. Something glitchy here? Can be more specific with some use cases if requested.
