Sound Parameters – Modulation Speed LevelsWaldorf microQ User´s Manual 46assigned to parameters through the Modulation Matrix and influence these parameters toalter a sound. In addition, the Modifier unit can process various mathematical operationsand functions on the modulation signals.Modulation Speed LevelsThe microQ offers three levels of modulation speeds: FM, Fast Modulation and Standard Modulation.This separation assures maximum flexibility in sound generation while keeping the amount ofprocessor power needed to calculate a voice as low as possible. You will find separate descriptions ofhow to access the different modulation types in the chapters below. The three modulation speedlevels are categorized as follows:FM (Frequency Modulation)This is the fastest modulation speed level. These calculations are performed for each generatedsample or, in other words, 48000 times per second (48kHz). Five modules of the microQ’s soundgeneration offer FM - the three oscillators and the two filters. When you browse the list of availablesources for this type of modulation, you will find almost exclusively those sources that make sense tomodulating the destination with sample speed. This includes the oscillators, noise, the LFO, theenvelopes and so on. You won’t find sources like modwheel or velocity, because their values changeincredibly slowly, compared to an oscillator playing at a pitch of i.e. 10kHz.

Most of the modulations in the microQ areperformed at this speed level. The following table lists all pre-routed Fast Modulation destinations:
