NEW Doepfer A-155-2 Mini Analog Sequencer & Friends - First Try of the 12HP #Eurorack Module

video upload by DreamsOfWires

"First play with the new Doepfer A-155-2 Mini Analog Sequencer, with A-111-5 Mini Synthesizer Voice, AJH Synth Tap Tempo VC-LFO and Chance Delay, along with a MiniMod voice for backing drone. The Mini Sequencer is a real 8-stage analogue step-sequencer, but with a few digital tricks up it's sleeve. For example, whilst it doesn't feature an internal clock or quantizer, it does allow you to save and recall step settings (except frequency), so you can switch between multiple behaviours simultaneously - very useful for live use. I've not tried this yet, but maybe in a follow-up video. Aside from that, there's step mute buttons, multiple play directions, 1-8 step pattern lengths, x2/x3/x4 ratcheting on each step, 1V/2V/4V CV range selector, and manual or CV reset. Not bad for 12hp. Here I'm using the Tap Tempo VC-LFO as the master clock, but also to produce random stepped voltages (like sample & hold) to modulate the Mini Synth's filter per step. This clock is then passed to the Chance Delay module, which restricts the probability of a gate or clock pulse passing through it, either manually controlled or by CV - more often this might be placed after the sequencer, so that steps (in this case notes) can be randomly skipped, whilst retaining the length of the sequence. However, I'm using it before the sequencer, so that all steps will be played in order (apart from when the sequencer is in random mode), but will do so across random steps - an effect I find quite satisfying sometimes. The rest of the patch is pretty self-explanatory if you have subtitles enabled. It was just an initial experiment really. More to come.

DISCLAIMER: This is NOT a paid video, I purchased the module myself, and no brand used in this video had any prior involvement or knowledge of me making it.

The Doepfer A-155-2 is a Miniature Analog Sequencer module that packs huge creative potential in a compact package. Using the A-155-2 is simple, yet a deep set of functionalities make it perfect for all things from basic repeating patterns to unique ratcheting and evolving sequences. Eight step positions each feature a knob for setting CV value, as well as an illuminated button to manually set gates on each step. At the bottom of the panel, outputs for a single pair of CV and gate signals are available, as well as clock and reset inputs. Along with a simple three-position switch for CV range, the A-155-2 offers a streamlined way to create driving patterns in any patch.

Beyond simple and unidirectional patterns, the A-155-2 enables plenty of creative options for crafting unique and lively sequences. Using the programming switch in combination with the step buttons, you can easily set up ratcheting rhythms for multiple gates per step, perfect for extending a melodic idea with stuttering syncopations. Additionally, sequence length and direction can be adjusted, allowing you to create longer patterns, evoke odd-time signatures, and experiment with random step playback. Finally, an eight-slot preset system is onboard, giving you the capability to store and recall your patterns between sessions and shows. Whether implemented as the brain of a small system or ticking along in a grand chorus of clocked control, the Doepfer A-155-2 Mini Analog Sequencer is a small triumph of modulatory movement for any case.
