A-156 : Incredibly useful module

9 years ago

I use this module on nearly every patch I set up. It's incredibly good for turning an LFO or a noise source into note CV and trigger output, all in time with an incoming clock pulse to create surprising pseudo-random arppegios and sequences of notes. The control switches allow for all the random notes to be kept in a specified key or chord rather than being just an unconnected series of notes so this module really helps to fill out a patch with constantly surprising and pleasing flurries of notes.

One thing worth noting is that there is a jumper on the board to set both channels to the same harmonic settings. I found this vital as without it the module will simply default to random semitones which rapidly becomes tiresome. With the jumper set you get more useful root, optional third, fifth and selectable 6th or seventh on major or minor chords.

overall, five stars all the way. I'm expanding my modular all the time and will definitely buy another of these. Highly recommended.
