Watch and listen to the demo patch below - module and demo patch available for download at bottom of post.
This is a new gate sequencer available for Audulus. It’s inspired by the QuBit Electronix Rhythm, which is a Eurorack module that contains a bunch of preset, ready-to-go beats available just by twisting a knob.
The advantage of this type of rhythm sequencing is that you can build songs lightning fast and do a way with a lot of the tedious work of rhythm programming - especially for styles of music like house that use essentially the same beat for every song.
Top right - gate input
This steps the sequencer forward. Clocking the sequencer with a 16th note pulse is recommended but not required - feel free to experiment with different divisions and timings, especially with multiple PBG sequencers in one patch.
Unlike many sequencers, this sequencer preserves gate height (dynamics) and gate width as the gate passes through the sequencer.
rs - Reset
A high gate at this input will reset the sequencer back to step one.
Top left - gate output
Where the sequencer gate passes through on to greater things
patt - Pattern selector 1-16
Selects one of 16 preset rhythmic patterns. This control cam be modulated to add even more variation to the preset beats.
The pattern is represented by the 4*4 grid of lights. Blue indicates a turned-on step of the sequencer, while red indicates the current step. The light will turn purple when blue and red collide.
Adding a step sequencer to control this parameter will allow you to string together a whole song of changing patterns.
The patterns are arranged so that if each bank is set to the same pattern, the patterns will always sound nice together. However feel free to experiment and mix and match patterns.
bank - Preset bank 1-4
Each bank contains 16 patterns. Each pattern bank is unique except for pattern 16 which is always “all on” to make it easy to create roll sounds.
The bank selected is indicated by one of four on/off green LEDs directly above the pattern display.
Bank 1: Kick
Bank 2: Snare
Bank 3: Hat
Bank 4: Tom/Bass
Don’t feel limited by the bank labels - or by staying on one bank all the time. You can of course use the kick bank for hats, the hat bank for snares, and the tom bank for hats. However the patterns are programmed in a way that they sound familiar and nice if you attach those sounds to their corresponding banks.
The style of beats hovers generally around house, techno, rock and hiphop. To make the sequencer swing, simply gate it with a swinging clock.
How it works
The creator of the module, Robert Syrett, came up with a brilliant way of storing 16 step gate sequences as a decimal number. With a helper module (included below), you can enter a sequence and get a special code of up to 5 digits to represent that sequence.
This number is then converted into binary and each digit of the resulting 16 digit binary number becomes one of the on (1) or off (0) states for each sequence step.
In the example above, the number 51540 converts to binary as 0010101010010011. The 1’s represent hits and 0’s represent skips.
The converter above tears that number apart into individual 1’s and 0’s and sends those numbers to the sequencer.
By using the helper module you can replace the preset banks and create a stable of your own sequences.
In the future more banks will be added (up to 16), and we’ll also add an on-board burst generator for creating fast rolls.
Download the patch and demos attached here, and let us know what you think! We’d love to hear or see any patches you make using it. You can upload Audulus files directly to the forum now!
Also, make sure you check out the ever-growing uModular (pronounced micro-modular) collection over at the Audulus forum. This new collection will eventually include over 1,000 new modules and many preset and template patches, each of which will be fully documented and include a demo showing typical uses. Modules are mini-fied to fit tightly together in small screen spaces like on iPhones and iPads.
You can follow the development of the uModular collection here.
Any feedback on the uModular format in general would also be appreciated! Thank you
