Doepfer A-137-1 Wave Multiplier I Модуль Waveshaper

The Doepfer A-137-1 Eurorack Wave Multiplier Module is a Voltage Controlled Waveform Multiplier. The basic idea of a wave multiplier is to multiply the waveform of an incoming signal (e.g. triangle from a VCO) within one period. This leads to additional harmonics. The period and consequently the pitch of the signals remains unchanged - in contrast to frequency multiplication e.g. with the PLL module A-196. The A-137 works as a kind of "inverse low pass filter", i.e. it adds a lot of harmonics to the incoming signal. Consequently the best results are obtained with signals that contain none or only a few harmonics (e.g. triangle or sine waveforms).

The A-137 can be used with signals rich in harmonics too (e.g. saw) but the effect is not as remarkable as for triangle or sine waves. The A-137 is a very sophisticated wave multiplier that offers many more features, more controls and more waveform manipulations than most other wave multipliers available on the market.
