'FAT BASS' - Bigger Sound for Synth Bass Lines using the Wave Swarm & Ring SM Eurorack modules

video upload by AJH Synth Official

"Some fat synth bass line sounds using a variation of 2 VCO, Ladder Filter, Wave Swarm for a thick sawtooth pad, and Ring SM for sub basses. Either or both of these 2 modules add a lot of scope to the sound of even a single VCO, even more so with two. Patch notes at the bottom.
The Wave Swarm uses it's 12 waveform animators to create thick, buzzing supersaw style sounds, from either a single saw wave, or from two independent saws, even as part of two completely separate monophonic synth voices, even a two-voice polyphonic patch. Check the links below for User Guide and some patches.
The Ring SM has both a vintage-voiced, fully analogue ring modulator, modelled on the ring mod from the EMS Synthi and VCS3, but it is also a 5-channel Moog CP3 style mixer, capable of soft clipping overdrive/distortion, and most importantly for bass patches - a sub bass/sub-octave generator, needing only a single VCO to generate both -1 and -2 sub octaves simultaneously. All functions can be used together, or on their own. The sub basses are shaped sine waves, which sound thicker and deeper than plain square waves, which are most commonly used by synths as sub basses.

AJH Patch of The Week: Mini Mod & Muting Mixer Melodic Performance (with patch sheet for Eurorack)

video upload by AJH Synth Official

"A re-recording of an old performance/composition using the AJH Synth Mini Mod system with the new MUTING MIXER & VCA module. This module allows input sources to be punched in and out quickly, ideal for live performance. Here I'm using one before the VCF to mix 5 waveforms from 3 VCOs, and also using another one as my final VCA after the filter. Patch sheet at the end of the video.

Patch Sheet: https://kvisit.com/8AE/jfYG

Patch Notes:
Green dots show approximate pot and switch positions. Where a pot or switch has two dots, this illustrates the range I move them during the video. Pots and switches that do not have green dots are not used in this patch, and should be left at their zero or off positions.
In the video I'm using the Glide + Noise MkII module to access the CV bus, allowing me to control multiple VCOs from one input/cable, otherwise you will need to use a multiple or stacking cables to connect the keyboard/sequencer to all 3 VCOs, as is usual with a fully modular synth.
VCOs: Tune them to the same pitch, only octaves are different. PWM SHAPE can be experimented with, setting all 3 VCOs to the same or different settings effects the sound of the combined pulse waves subtly.
Muting Mixer: These settings allow me to switch O/DR (overdrive) on and off without driving the signal too high, and keeping both states at a comparable level. Notice I always un-mute either the pulse waves (channels 2 & 3) OR the sawtooth waves (4 & 5) of VCO 2 & 3, never both pairs at the same time, as their combined signal would significantly increase the input level and risk unwanted clipping distortion. I tweak the level of VCO 1 (channel 1) to drive the signal a little more, but however you use it try to keep the level meter in the GREEN.
VCA: In the video I use another Muting Mixer as final output VCA, so in the diagram I show the Discrete VCA being used for the benefit of those who have one, but the same principle applies - set master to full then gradually increase the input level.
Modules used from top-left to bottom-right: Glide + Noise (for bus board access - optional), Vintage Transistor Core VCO x3, Muting Mixer, Transistor Ladder Filter, Contour Generators, Discrete Cascaded VCA (or Muting Mixer)."

'Für Klaus' - Tribute to Klaus Schulze, a Eurorack Modular Performance #eurorack #synth #ajhsynth

video upload by AJH Synth Official

"On this channel Sunday 8th @7pm GMT - a 13-minute track recorded as a single-take performance, and a purpose-made tribute/dedication to the late Klaus Schulze. The piece is inspired by his music directly, creating some sounds akin to those he used in the late 1970's, even including one of his sequences. Much of it was composed and rehearsed, whilst some of it was improvised, but I suspect much less so than Schulze's works, which were often much longer, involving more improvisation and more instruments. This piece consists of just three voices across 4 audio tracks/channels, altered or converted in real-time during the performance to achieve different sounds.

As a creator of electronic music, Schulze was one of the most significant influences for me (the video creator). His music, his attitude towards it in the interviews I read of his, and the way he worked alone to create dense, fascinating, complete musical performances and soundscapes, at a time when the technology was in it's infancy, and before later technologies such as complex computer sequencing, sound creation, processing and mixing were available. As a solitary musician, his was a great, empowering example. His bravery to improvise, experiment, and co-exist with imperfections, embracing them rather than fearing them, makes me warm to the artist and the music even more. Schulze used, among others, an early Minimoog (leads) and a large Moog modular system, which he customised with additional modules over the following years. Since the core AJH MiniMod system is directly based on the early, more desirable R.A.Moog version of the Minimoog, yet is entirely modular, it makes a great choice for this homage to one of electronic music's greatest pioneers.

AJH Synth NEW! MULTI BURST ENVELOPES

NEW! MULTI BURST ENVELOPES - An 8-shape envelope generator, with multiple time-controlled repeats video upload by AJH Synth Official

"An introduction and brief overview of the new MULTI BURST ENVELOPES from AJH Synth." Video by DreamsOfWires

The MiniMod Multi Burst Envelopes module generates variable length bursts of repeating envelopes that can change over time, with CV control of all functions.

The BURSTS control selects a 'Burst Sequence' of between 1 and 40 bursts. The envelope shape of a burst is chosen with the rotary switch, or it can be varied using an external CV, so that it is even possible to chose a different envelope shape for each individual burst in a sequence.

The width of the envelope (i.e. the attack and decay time) is varied with the P-WIDTH control and this can also be CV controlled as a sequence is progressing, so it is possible to vary the envelope speed of each individual envelope burst while a Burst Sequence is running.

The repeat time of individual bursts in a Burst Sequence is set with the LFO Rate control. The LFO rate can be varied with an external CV as a sequence is progressing, so the gap between envelopes can speed up or slow down over time. An external clock can also time the bursts in a burst sequence instead of, or in addition to the internal LFO. Bursts can also be manually incremented with the CLK push button.

The SLOPE control allows Bursts to start quietly and build in level to maximum, or they can start at full level and then reduce in level as the Burst Sequence progresses. In the centre position all Bursts are of equal level.

Full USER GUIDE video available 30 minutes after this video goes live.

'Old School Jam' All-modular, Step Sequencer, Bucket Brigade Delay, Eurorack FX, and no quantiser!

video upload by AJH Synth Official

"Un-quantised, old-school sequencer fun: Inspired by early sequenced electronica such as Tangerine Dream and Klaus Schulze, much of whose music used a Moog 960 sequencer, which didn't have quantising features, and were sometimes difficult to tune accurately or reliably. Such as the track 'Phaedra' by Tangerine Dream, during which the Moog performing the opening pattern had to be re-tuned during the actual recording, and it was left on the album! Yet it sounds great, it's imperfect tuning adds so much to the atmosphere of the music, irrespective if it was deliberate or a 'happy accident'.

Here I use an un-quantised sequencer, in fact an Erica Synths Sequential Switch, with it's CV expander that turns it into a great little 8-step sequencer. I also run it through the AJH Synth CV Mix, to offset the CV going to the oscillator, allowing me to push the output into the negative CV range. I then send this shifted signal to the VCO's frequency modulation input instead of the 1V/Oct... just to make it more difficult to tune! Seriously though, this was a fun experiment, and taking off the digital stabilisers (or quantisers) once in a while is highly recommended, and a good learning experience. This was an all-modular session - no external FX or mixing, just Eurorack modules for all functions.

TRIPLE CROSS: How to create Circular/3D Panning effect with this Eurorack Stereo Cross-fader module

video upload by AJH Synth Official

"The new Triple Cross module from AJH Synth & Tone Science is a 3-channel stereo cross-fader/panner, fully voltage controlled, and able to be used for a plethora of different audio or CV duties. Here it is being used to achieve a dual VCA, stereo panning and cross-fading simultaneously, alternately raising and lowering the volume of 1 or 2 incoming audio signals, whilst moving them between left and right outputs. This can be used to create a 3D impression a sound that is moving in a circular motion.
This might more often be useful for creating momentary effects, and could be especially interesting for ambient drones, but here I demonstrate it using a sequencer, and eventually 2 melodic synth voices playing different patterns. An important element in this patch is the modulation - I use the Dual LFO +VCA module to create a quadrature triangle LFO, so I have 2 triangle waves running at the same speed, but at a 25%/1 quadrant difference in their duty cycle. Here it's achieved by using the square wave of one LFO to sync the other.

Patch of The Week: Analogue Kick Drums in Eurorack with the AJH Synth MiniMod Modular Synth System

video upload by AJH Synth Official

"A simple analogue kick drum patch easily recreated in Eurorack, or even some self-contained synths. This isn't modelled on a particular classic or vintage kick sound, but uses a common process for creating such a sound that is easily tweakable to suit your own ears. Check out our past 'Patch of The Week' videos for other percussion sounds, including analog claps, and using a self-oscillating filter to create various claves, rim shots, cowbell, even a rudimentary kick.

PATCH NOTES:
------------------------
Download PDF with diagram - https://kvisit.com/8AE/qvwG
Green dots show approximate pot and switch positions, and where there are 2 dots on the same pot, this indicates the range I adjust them during the video. Pots and switches that do not have green dots are not used in this patch, and should be left at their zero or off positions.
GLIDE + NOISE: I used the white noise in this patch - not all vintage kick drum sounds used a noise source, but it is optional based on personal taste. I find it gives the sound a more similar character to a real kick drum, whereas without it the sound is more distinctly electronic.
VCO: A good kick sound can be generated using just the filter in self-oscillation, but using a dedicated VCO provides greater flexibility, especially when combining with other audio sources, such as white noise. Base pitch and level of Exp CV from the envelope should be experimented with.
VCF: Envelope control of filter frequency will not make much difference to the sound without the white noise, as then you would only be filtering a triangle wave. This is why I've simply copied the envelope that's also opening the VCA.
ENVELOPE: Ideally there needs to be separate envelopes for the VCO and the VCA/VCF, as one is controlling pitch, and the other volume (& tone), which both have a very different impact on the sound. A pair of DH-ADSR's would offer greater dynamic control, as mentioned in the video, but the CONTOUR GENERATORS is fine too.
VCA: The DISCRETE CASCADED VCA allows a little bit of overdrive when input levels are pushed. Even more so when used with the GAIN SWITCH (See our other videos), but also the MUTING MIXER can be used, as it's built around the same VCA circuit and has a built-in overdrive function."

Patch of The Week: 'Assault on Precinct 13' Gemini 2412 Bass Cover (1976 John Carpenter soundtrack)

video upload by AJH Synth Official

"Just for fun, a patch inspired by a classic synth soundtrack from the 1970's. This time using the Gemini 2412, 1 VCO and Ring SM to create a version of John Carpenter's excellent soundtrack for his 1976 movie 'Assault on Precinct 13'. I don't know for certain, but I've a hunch that he might have used an Oberheim SEM module (or perhaps one of it's polyphonic configurations; Four Voice etc), as it sounds like one in the bass part at least, so I've used the Gemini 2412 to simulate it, since this VCF is based on the SEM filter. The SEM (Synthesizer Expander Module) was a classic 2-oscillator analogue synth module from 1975. It sounds to me like a single sawtooth being used in the movie theme, but I add an additional sub-octave using the Ring SM - it's a cover version, not an attempt to recreate it 100%.

I use the Muting Mixer for the VCA, along with it's overdrive function, to create a more aggressive, punchy bass sound, somehow more befitting a dark, low-budget thriller movie of the seventies. I also chose a reverb setting that to me sounded a little claustrophobic. Patch Notes and PDF link further down the page.

Minimal Jam: Chance Delay & Entropic Doom - random gates, melodic noise, analogue percussion

video upload by AJH Synth Official

"A minimal jam using 2 Chance Delay modules, triggered by a sequencer clock, with the Entropic Doom to create both percussive and melodic noise-based sounds. Also a simple dual-oscillator analogue bass line using 2 Vintage Transistor Core VCOs and the Transistor Ladder Filter. Turn on Subtitles/Captions for an explanation of what's going on.

The Chance Delay generates randomness with its 'Chance' control, which determines the probability of gates occurring. It also uses its Length control to divide the frequency of the incoming clock signal - this is done by forcing the gate lengths to exceed the interval between clock pulses, and not producing further gates until the current gate cycle has finished. It also has a gate-delay function, and all three of these features can be voltage-controlled.

The Entropic Doom is a noise generator with a built-in, voltage-controlled, low-pass filter. This VCF has 2, 3 and 4-pole modes, and is resonant, producing significant self-oscillation in 4-pole mode, whilst also tracking 1V/Oct. This means it can be used melodically, extending it's usefulness beyond just noise washes or percussion. Additionally, it includes an audio input to add other signals into the pre-filter feedback loop, and it can sync it's noise frequency to an external source. To top it off it also features a CMOS ring modulator and XOR VCA, both of which can be used with or without the rest of the module. This thing can go from subtle and pretty timbres to crushing, mangled, distorted chaos.

SAMPLE HOLD & SLEW User Guide: Multi-function Eurorack Modulation, Noise, Internal & External Clock

video upload by AJH Synth Official

"The SAMPLE HOLD & SLEW is a 12hp Eurorack modulation source, featuring both sample & hold, track & hold, a restrict function, internal noise source with colour control that can also be used as audio, internal clock that can be sent to other modules, and external clock control. It also has a well-featured Slew section, with selectable slew up and down only, gate control to switch it on and off, linear or exponential response, and this section can be used completely independently from the rest of the module.
This module can function extremely well independently, having it's own built-in clock and noise source to generate random voltages. However, it can also serve as a master clock for a generative patch, or triggering a sequencer. Alternatively, it can be slaved to a sequencer's clock, the gate output of any CV controller/keyboard, or other modules, so that it can generate random voltages in time with the music, even allowing the slew (or glide) to be added to individual steps in a sequence or pattern. This module is brilliant for making sequences more interesting.
As a simple noise source the bi-directional colour control applies low-pass or high-pass filtering. This is also useful when used with the sample/track & hold to determine the range of random frequencies or voltages that will be generated, as is the Clipped noise feature, which creates more significant differences between each sample, and the Restrict control that limits how far each new generated voltage can be from the last. When also used with the Slew and Exponential features it can then generate a smooth, ever-changing CV signal, which is ideal for use in drone sounds, modulating a VCF, VCO, VCA, an LFO, and any other modulation or audio.

MiniMod & Ribbon Controller - AJH Synth Eurorack Ambient with Gemini 2412 'SEM' style Dual Filter

video upload by AJH Synth Official

"A 2-voice ambient performance using the Doepfer ribbon controller with the AJH Synth MiniMod eurorack modular system, here incorporating the Gemini 2412 'SEM-based' dual multimode filter/VCF. Simple 2 note/2 VCO chords are shifted in pitch with the Ribbon, and pressure sensitivity used to control the Gemini's overall frequency, and the level of pitch vibrato from the Dual LFO module, which has a built-in VCA. A third VCO via the Transistor Ladder Filter creates a single oscillator drone sound (a square wave with pulse width modulation/PWM), whilst the Dual LFO also modulates the frequency of this VCF, and both VCF's on the Gemini in position to each other. The Gemini is used as a stereo filter, with both going of it's VCF's going to separate VCA's and audio channels to creates a stereo panning effect.
The Gemini can be used as 2 filters in series, or in stereo with a single audio input signal, but here both filters are processing a different VCO via their individual inputs, whilst the global Dual Frequency CV function of the module's central mix bus section allows them both to be controlled in unison, in addition to, or instead of their own individual CV control. This offers a huge amount of flexibility.
A suitably large reverb is added in post to add a film/movie soundtrack quality to the sound.

New TAP TEMPO VC-LFO 16-Wave Eurorack Module by AJH Synth

NEW! TAP TEMPO VC-LFO 16-wave voltage-controlled modulation Eurorack module with VCA, Int/Ext clock
video upload by AJH Synth Official

"The TAP TEMPO VC-LFO is a skiff-friendly, 42hp Eurorack low frequency oscillator. It's a modulation powerhouse, with 16 waveforms, 15 with 'wave form twist' PWM-like control, random sample & hold type waves, and CV control over all functions.It can serve as a clock source, or can be clocked by external pulse/gate signals, with a clock multiply/divide function, along with a built-in VCA controlling both bipolar (LFO type) and unipolar (envelope-type) outputs. It's great for everything from simple expression-controlled pitch vibrato, to clocking or being clocked by sequencers for time-synced modulation, and generative patches, where randomness and/or time control is needed to be shared between different modules.

Every modular system needs modulation sources to add variety and interest to static sounds. The more powerful and versatile the modulator, then the more interesting these sounds can become. We compiled a wish list of useful features, starting with obvious ones such as CV control of Frequency, Tap Tempo, Unipolar and Bipolar outputs and a wide range of waveforms, and then we just kept adding more features such as waveform twist, rate multiplication, Sync In/Out and an inbuilt dual VCA for modulation level control. Then we made sure that we had voltage control (and therefore automation) available for every single feature. This takes it way beyond the realms of regular LFO's and make the Tap Tempo VC-LFO a modulation powerhouse.

Ergonomics are important too, it can really spoil the workflow if we have to stop and refer to the user manual to find out what some obscure control or jack socket does - so it follows our usual format of having a very clear, intuitive and uncluttered front panel. All of the jack sockets are in two rows at the bottom, with the inputs on the left and outputs on the right hand side.

The Tap Tempo VC-LFO is available with either a Black or Silver front panel.

'Filter on Filter' Jam: Ladder into Fixed Filter Bank 914 & Lunar Module 'Bit-crushing' Drum Sounds

"Minimal Synth & Percussion Jam: 3 VCO's into Ladder Filter, then Fixed Filter Bank 914, with DH-ADSR envelope control over mix of both filters. Also down-sampling/bit-reduction effect using the Lunar Module to crunch then distort incoming audio/drum pattern from an iOS app (Patterning 1).

The classic Moog Modular-based Fixed Filter Bank 914 totally transforms the sonic character of the output from the Minimoog-based 24dB low pass VCF, creating a vocal/choir timbre, which is fed 3 sawtooth waves, each with their own LFO/modulation. The envelope automates the FFB module's built-in mixer, morphing the sound from just the Ladder VCF, to the Ladder through the Fixed Filter Bank. The Lunar Module is great for taking a too-hi-fi sound and giving it some lo-fi character, with optional crunchy distortion, making it sit more comfortably alongside it's analogue Eurorack neighbours.

This first episode covers the sound of the melody and programming the sequence, then Episode 2 (next Sunday) will cover the mysterious percussion (no, it wasn't Nick Mason :P).
In this version just one square wave from a MiniMod VCO is used, and the filter is specifically the Sonic XV, as this is also a 24dB diode ladder filter like the VCF on the Synthi AKS. The only other modules needed are a VCA and an LFO. I also use the Sonic XV's 6dB output - to me this sounds more reminiscent of the Roland TB-303, which actually used an 18dB diode ladder filter, and it gets similarly squelchy with high resonance.
I also experiment using an ADR envelope on the filter frequency - this is a fast sequence, but the Sonic XV responds really nicely to fast envelopes.
Sequencing is courtesy of Doepfer's splendid Dark Time step sequencer, but I also demonstrate using an Arturia Keystep, as this is actually closer to the method used on the AKS version of the Synthi, which came with a digital keyboard sequencer that was significantly ahead of it's time in 1972.

Patch Notes:
Green dots show approximate pot and switch positions. Those with two dots show the range I adjust them during the video. Pots and switches that do not have green dots are not used in this patch, and should be left at their zero or off positions.
SONIC XV: This gets us fairly close to the Synthi's sound, as it shares some lineage from the original diode ladder VCF. I use both 24dB, as the original Synthi filter was 24dB, but also the 6dB output, because in 24dB it is easier to send the filter into self-oscillation when using high resonance, and this sound really benefits from a lot of it. The 6dB can achieve a more noticeable degree of resonance before self-oscillation occurs. It is subjective, and both have their character and strengths, so experiment!
MUTING MIXER or CASCADED VCA: You could also use the Discrete Cascaded VCA for this patch, keeping the Master level high and increasing the Input level until sufficient output volume is achieved. The only reason I used the Muting Mixer here was so I could easily switch between the audio from both 6dB and 24dB outputs of the SONIC XV. If you are using the MUTING MIXER be careful about enabling both inputs at the same time, it will result in an increase in volume, as you are adding audio levels (dB) to each other. It can be very musically useful to do so of course, and worth experimenting with, but bear in mind your overall output level.
Modules used from top-left to bottom-right: Dual LFO + VCA, Vintage Transistor Core VCO, Sonic XV Diode Ladder Wave Filter, Muting Mixer & VCA."

Patch of The Week: Choir Sound 1 - Tutorial with patch chart and demo performance

video upload by AJH Synth Official

"A simple choir-like timbre using multiple VCOs, including examples with 3 different filters, how to use modulation to add realism, a short performance demonstration, and patch diagram at the end (with notes and full downloadable patch sheet in the description).
This version uses 3 analogue oscillators, being modulated separately, to simulate the imperfect tuning of multiple human voices singing together. There are more advanced methods to create vocal-like sounds, such as those used in synths like the Roland VP330, but it can be difficult (and possibly hugely expensive) to represent the components used within the modular domain. However, if a comparable sound is achieved in a modular format then the degree to which it can be tweaked and customised is limitless, which can't be said for the self-contained instruments of the past.

Step Sequencer & Fixed Filter Bank 914 - An alternative to a VCF for sculpting sequences

video upload by AJH Synth Official

"This 'Patch of The Week' shows the Fixed Filter Bank 914 being used instead of a typical voltage-controlled filter to sculpt the sound of a step sequencer pattern, and also how on this particular module the sequencer can also interact with it for more variation and movement. The module is based on the original 914 unit from the vintage Moog modular systems, something Klaus Schulze was very keen on using as part of his 'Big Moog' that he used for much of his music career.
Here the excellent Doepfer Dark Time sequencer is used, but any dual, or combination of 2 step sequences could be used.

MiniMod Keyz & Arps - Keyboard Split function and Dual Arpeggiator running 2 synth voices

video upload by AJH Synth Official

"Full-length 'landscape view' video on Sunday. Using the keyboard split function of the Nifty Keyz with an arpeggiator on both keyboard zones. This is then controlling both the on-board MiniMod voice and a separate Eurorack case, containing another 3-VCO voice and the Gemini 2412 Dual State-variable VCF. These 2 SEM-style filters are processing the same sound very differently, and are modulated the Dual RVG random voltage event generator, and the Multi Burst Envelopes. The MiniMod Keyz voice uses the Ring SM as a mixer and sub-bass/sub-octave generator, along with the classic Minimoog-based Transistor Ladder Filter.
