Harmonic generator/synthesizer/vocoder

HG-30 is a multimodal Eurorack module which has 14 different operating modes. It is a new introduction by the company Audiospektri Finland Oy, see www.audiospektri.com for a complete manual of all the features. The name comes from the basic operating mode of 30 controllable harmonic frequencies, but the more complex modes include e.g. vocoders, PM, FM and noise synthesis, as well as pseudo-VCF. It uses mostly additive synthesis, but some modes also use subtractive, filtering based synthesis. It has inputs for 8 external envelope generators that can be SW routed to control the various parameters of the module. It also requires an external MIDI interface module to feed the VC note, pitch bend, and velocity inputs. Several sound samples from the operating modes can also be listened at the website or Soundcloud.
