SEQUENCERS and PATTERN GENERATION

A Sequencer is used to generate reoccurring rhythmic patterns, often by triggering sequences of notes in synthesizers or drum machines. However sequencers can be used for purposes other than triggering notes - they can be set up to create reoccurring changes of timbre as well. Vintage sequencers were typically designed so there were a certain number of “steps”. The term “step” refers to the individual components of a pattern. For instance in a bar of music in 4/4 you have four quarter notes. If the rhythmic activity is no more complicated than quarter notes, this would correspond to four steps. In many vintage or analog sequencers, a sequencer typically had eight or sixteen steps available to build a pattern.

In its simplest form, as a sequencer plays back its steps, each step can be programmed to send a trigger signal - or not - a step can be passed over like a musical rest. The trigger signals can then be used to trigger envelope generators according to the way each step is programmed - creating a rhythmically reoccurring pattern.

The Bass MuRF’s Animation contains 8 simple sequencers, one for each filter, each capable of triggering an Envelope Generator that shapes the volume of the filter.

ANIMATION

The Bass MuRF’s ANIMATION module is designed as a means of automatically turning the levels of the individual filters up and down, using envelope generators, according to a pre- programmed pattern. The ENVELOPE control morphs through different envelope shapes as you turn it, creating effects that are highly rhythmic in nature, or are swirling and ethereal. The RATE control sets the speed of the pattern. The patterns, selected by the PATTERN selector rotary switch in conjunction with the Bank slider switch, have been selected to provide a surprisingly wide variety of rhythmic timbral effects. There are a total of 24 patterns,
