ALM Busy Circuits Mum M8

ALM Busy Circuits

Regular price $299.00

‘MUM M8’ is an 8hp Eurorack low pass filter building on the filter design used in the classic Akai S950 12 bit sampler with the addition of resonance, voltage control, clipped saturation and a dedicated VCA.

The low pass filter gives the recognisable super smooth vacuum like tone sucking sound which works magic on complex sources. The addition of clipped overdrive and intentionally aggressive self oscillating resonance compliment the smooth filter core by juxtaposing it into more wasp like territory with acidic squeals and a more gritty sound.

The filter core is a 6th Order Butterworth switched capacitor type design featuring an analog core but controlled by a high speed digital clock. This produces the characteristic smooth sounding filter but, as with the original S950, has a relatively high minimum cut off as to avoid ‘clock bleed’ into the filter output from the digital control. This minimum cut of point can be controlled via trimmers on the rear of the module.
