"Modules used and some brief patch notes:

All sequencing is programmed on a pair of ER-101's, one of which is coupled to a ER-102 sister controller module.

Continuing on my journey of creating music solely on a modular synthesiser, this song has been in the works for a while (a lot longer than I would usually spend on a patch anyway) partially because i'm expecting an ER-301 any day now after a long lead time, I wanted to integrate the 301 as i'm interested how the 301 is going to affect the music I can create in a modular environment, i'm excited to sink my teeth into it. Secondly to that, I felt an emotional connection with this track i've enjoyed listening to it, exploring it and programming it.

At the heart of my rack is a pair of ER-101's that do all of the sequencing, each one has 4 tracks, each track has 3 outputs (CV-A,CV--B and GATE) I will often use CV-A for melody or pitch and CV-B for distributing control voltages to parameters around the rack, if however CV-A is on a track that is only outputting Gates that gives me 2 channels of CV that can be fine tuned to any value, lots of control just the way I like it. I've always written music in a DAW, and the ER-101 pair allows me to approach sequencing in a similar, reserved and meticulous way.

They provide me with all the brushes I need for my paintings.

There are 3 main voices,
- Elements in Ominous Voice mode 4x4 FM operator, which is the main melody. Damping controls the amount of filter modulation from the internal envelope on the output of Elements, so to add accents and introduce more frequency content. CV-B track 3 on the ER-101 controls damping, and the entirety of track 3 controls Elements.
- Loquelic Iteritas - in SS mode playing chords with rings. Some modulation sent from Ornament and Crime controls FOLD (introducing more frequency content) using the same gate to trigger a different envelope.
- Rings in 2x2 FM operator mode, tuned to a nice interval for nice dispersion of harmonics. This plays chords with Loquelic (and itself, polyphony is set to 4 voices), small amount of modulation to the POSITION on Rings, controlling the feedback between oscillators creating some really nice beating on the lower frequencies. Rings is sent to the Erbe-verb which is always modulating itself so the internal Lfo is set to 11.30, decay is set to 12.00, Depth at 14.00 decreasing the depth of modulation, Tilt at 10.00 filtering out some of the upper harmonics and absorb is at 12.00 also filtering / dulling, ultimately thickening the sound the Erbe-verb is fantastic.

Clouds is processing Loquelic, creating random grains and adding reverb

DPO - is used for the kick created using Streams as a VCA / Envelope combo Exponential envelope and a second envelope from MATHS to modulate the exponential FM input on the DPO for a sharp descending pitch.

DPO second oscillator FINAL output is used to create the percussion, fm sent from VCO-A to VCO-B FM index all the way up, Exponential attenuator full lock, linear at 10.00. Sent to Dual looping delay, the DLD's parameters are modulated by the ER-101.

Braids is used to create a snare, using its internal envelopes / modulation. Also sent to the DLD, delay time is modulated from really short times to slower, to create fills.

Belgrad is filtering the Loquelic Iteritas' more digital harmonics out. with 2 different resonant peaks, allowing me to pick out the harmonics I thought sounded best.

Sequencing with Probability (Advanced Techniques for the ER-101/102)

Sequencing with Probability (Advanced Techniques for the ER-101/102) from Orthogonal Devices on Vimeo.

"A user asked on the forums how one can introduce probabilities into the ER-101/102 sequencing and thus this video was made to explain one method. The video is a quick tutorial on how to have individual steps trigger (or not) according to a (per-step) probability.

You can do this with the non-destructive transforms of the ER-102 groups because these transforms get re-evaluated every time the step is played. The trick is to get the ER-101/102 to threshold the output of the random operators. In other words, to get different probabilities just use the fact that parameters are clamped to be at least greater than zero and then combine the subtract operation with either the jitter (jt) operation or the (rd) operation.

For example, suppose we have 8 steps that are all the same DURATION=16 but have the following TRIGGER lengths (i.e. GATE lengths but track is set to TRIGGER mode):

1. 21
2. 0
3. 8
4. 6
5. 21
6. 0
7. 15
8. 5

Then we add these steps to GROUP #1 and set the X/LOW transform of GROUP #1 to

A = -20 (i.e. subtract 20)
rd = 20 (i.e. add a random number between 0 and 20)

The steps with the larger TRIGGER lengths will have a higher probability of being greater than zero after the group transform is applied. This way you can set the effective probability of a non-zero TRIGGER length per-step. In the example above, steps 1, and 5 will always fire but steps 2 and 6 will never fire. The other steps will fire with probability proportional to their TRIGGER length with anything greater than 20 having 100% probability. It's quite fun and allows you to create ever changing rhythms that nevertheless have a clear groove, in fact any groove that you want. Finally, you can use the MOD bus to control the 'probabilities' with external CV."

ROLAND SH-101 + KORG ER-1 ~ Will They Pair? Ep.21

once upon a synth
Published on Aug 9, 2017

"Pairing the Roland SH-101 with a Korg ER-1. The SH-101 is a vintage analog monophonic synthesizer from the 80s. The ER-1 is a digital drum machine from the 90s. Together they ooze vintage 90s techno/house vibes which I explore in this video. I'm largely using preset patterns on the ER-1. The ER-1 is outputting MIDI clock which I then convert into CV and feed into the clock input of the SH-101 to synchronize the sequencer. The SH-101 is then run through the ER-1 via its external audio input."

twinCUSSION 4

Published on Oct 18, 2018 vermonagear

"This video presents a small patch using only the available space within our Modular Case 104. If you follow our performance, you will find us mainly playing this patch using the modules’ switches and buttons. While we were pleased with the sound of this patch and found it worth being published we also found it worth showcasing such method of patch control where we cannot mess anything up as switches and buttons allow for jumping between settings at no risk.

twinVCFilter

The twinVCFilter is driven into self-oscillation on both sections, forming a dual sine wave oscillator. The first sections’ frequency modulates the second section for enhanced timbre control.
Both filter sections are controlled by the ER-101.
The filter’s output is fed to the Morphing Terrarium’s (MT) sync input while the output of the MT is used to amplitude-modulate the twinVCFilter’s output. Mostly we let the MT run at lower frequencies to misuse it as an envelope generator in this patch. This does not work just perfect, but it also shows how flexible modular can be.

twinCUSSION 1 (left)

Section A is pitch-modulated by a mix of its envelope output and its sine wave output. This allows bending the waveforms symmetry while retaining the pre-patched pitch bend. Toggling the frequency range switch to HI while shortening the envelope’s decay drastically down gives a nice and sharp click sound and makes up for an excellent alternative to the voluminous kick, that we achieve when setting the range switch to LO position while increasing the decay again.
Section B receives CV-data from the ER-101 sequencer. We also routed a voiceover into the square wave output, where it gets mangled with the internal waveform. By toggling the waveform switch, we can drastically change the final output of this section.

twinCUSSION 2 (right)

Section A receives the noise output of twinCUSSION 1 which is being amplified using the twinVCAmp. This way we trim the mix ratio between internal and external signals. Thus we can select between clean and noisy sounds to switch between drums and snare.
Section B generates the hihats and is amplitude-modulated by its sine wave outputs resulting in some tremolo-like effect.

The sum of all drum sounds is amplitude-modulated by an envelope to achieve global dynamic control over the drums itself and the inserted voice sample.

We hope you enjoyed this patch and that we could lift your imagination in modular ways.
Thanks for watching!

ER-301 / Morphagene / Eurorack Ambient Guitar Synthesis

Published on Dec 18, 2017 Drink The Corpse Vomit

"DRINK THE CORPSE VOMIT PRESENTS - GORE GAS

Patch Notes:

More guitar tones made from scratch. Raw tones through a few ER-301 Convolution units sound really convincing to my ears. The pick sounds are pitched independently to the sustained notes adding further depth.

The sounds for each of the 2 'guitar' voices are 4 voice polyphonic and triggered with the new Bump unit to let the notes ring out. I think this is called 'hocketing' and works similarly to the Intellijel Shifty. The lead voice is played badly by hand, the supporting voice is sequenced by the ER-101 via the ER-102 real time record function.

The lead voice is through the Fairfield Circuitry Shallow Water and Lofi Junky. The supporting voice is through the Chase Bliss Warped Vinyl 2.

Morphagene is graining a pre-prepared 'string' section of some wavefolded sines. Into a Cwejman saturation chain ( MMF-6 etc. )

Each separate track is printed to an Orion 32 via a Praxis Snake Charmer - A pristine audio route that is wasted on this filth."
