1. There are 2 OSC HRM oscillators in the Hordijk system. The design of the OSC HRM was originally conceived in the 1980’s. Firstly, in a digital form then in the analogue domain to improve the auditory result. OSC HRM combines cosine and sine calculations to produce a rich harmonic series containing both odd and even partials. Each oscillator is temperature controlled to provide accurate pitch stability.

    OSC HRM functions:
    VCA LVL
    ALL HRM - Saw wave generator
    ODD HRM - Sine to Pulse wave generator
    PITCH FINE
    VCA MOD
    HRM MOD
    PITCH MOD
    PITCH (manual)

    All parameters of OSC HRM can be modulated using control voltages (CV). The OSC HARM contains inbuilt distortion. This can be further enhanced by connecting the output of the OSC HARM into the 24dB FILTER.

    Q1: When the VCA controls the output of an oscillator, does it have a consequence to filtering?

    The OSC HARM contains inbuilt distortion. This can be further enhanced by connecting the output of the OSC HARM into the 24dB FILTER.

  5. Main functions of the Hordijk Modular System can be categorized as generators, treatments and mixing. Generators produce waveforms; in the audible range, LFOs (low frequency oscillators) and supersonic generators. In this chapter, Rob explains the three components of traditional analogue synthesis that emerged in the early 1960’s. Where analogue sound was defined as three properties of sound as they move over time; Pitch, Loudness and Timbre. Drawing comparisons to exciter and resonance models devised by Helmholtz in 1850. In a way, the Helmholtz resonator provides the basis for the analogue modular synthesiser designer Bob Moog’s in the 1960’s.

    In this chapter, Rob explains the three components of traditional analogue synthesis that emerged in the early 1960’s. Where sound is defined as three properties that move over time; Pitch, Loudness and Timbre. A process he calls ‘modulation’. Drawing comparisons to the exciter and resonance model devised by Helmholtz in 1850. In a way, the Helmholtz resonator provides the basis for the analogue modular synthesiser design of Bob Moog in the 1960’s.
