After Later Audio

Notes: The randomness of the Music Thing Modular Turing Machine, in the Intellijel 1U format. Alan retains all of the same functionality as the original including the connectors for the expanders.

While this module has little to do with the original Turing Machine (by Alan Turing), it is a shift register based sequencer. You cannot program this sequencer, instead it builds random sequences that can be locked in.

Alan comes tested, calibrated and ready to bring random voltages.

Notes: Two channel expander for Bartender

Mixer section

Each channel has the following:

Stereo or mono - Each channel can be treated as a stereo channel or a mono channel with two summed inputs.

CV inputs for both panning and level control

Two send buses - You can route each channel to one of two send buses. Each send bus is stereo. You can choose if you want the send to come before or after the level/panning controls.

Mute - The mute has both latching mute (up) and a momentary mute (down). The mute uses a capacitor to slow the turn off and on of the mute action. So it is mostly click-less, but you may find an occasional pop.

Cue bus - You can route each channel to the cue bus.

Expandable Mixer Series

Bartenders can be cascaded to create 8ch, 12ch, or 16ch mixer. The main level is what is sent the main level control can act as a group control.

Barbacks can be added to add 2ch to your mix. Barbacks can also be cascaded enabling up to a 16ch mixer configuration.

Send-VCA can be added for CV control of the level of the send.

DVCA, Cast Iron, Mingles, and USB-2CH can all be connected with Dupont cables (aka female to female breadboard cables) via pin headers on the back of the modules. Connecting the in and out pins will send/receive the audio into the next module.

Width: 10hp

-12V: 100mA

Notes: Cascades is After Later Audio's most fully featured analogue oscillator. Some of the unique features are:

Through zero FM oscillator
Morph output with CV control to morph between TRI, SAW and PUL waves.
Octave switch to simplify tuning
Cosine output - fun for stereo - also for going full analogue quadrature with the SUM+INV module
VCO and LFO ranges
Amplitude modulation built-in with either offset or full wave rectification for the modulating wave.
Switchable mod wave output between morph out and SIN (jumper on back)

Two notes:

The COS output can only be tuned to work with either the VCO or LFO range. At the "factory", After Later Audio have tuned it for VCO usage. Stay tuned for tuning instructions if you would prefer to use it for LFO range.

The chip used for the core of this module is the SSI2130, which has a tendency to lock up on startup when the power rails come up asymmetrically, which is most common in Intellijel power supplies. If the unit does lock up on startup, just flip the LFO/VCO switch to get it behaving.

COCO - Create your Own Complex Oscillator

With COCO system the aim is to bring all the goodness of a complex oscillator while aiming to minimize some of the downsides. The main thing that I appreciate about them is that you can have a lot of fun without having to patch too much. By default, you can get some very deep sounds that go far beyond the standard bleep and bloop. On the downside, complex oscillators are big and have a fixed set of capabilities.

The COCO system allows you to choose your oscillator features and choose your control module and connect them all together into a complex oscillator. You can then break them down and each module also works as a standalone module as well. So when you need that extra oscillator for your performance case, you can break the system down and use it accordingly.

Oscillators

You can connect up to a total of three oscillators in a complete COCO system. It is recommended to have at least two or it will not be much fun as a system. The typical configuration would be having one Cascades and two Brooks.
Each oscillator in the COCO series can send and receive Exp FM, sync, and a MOD bus.

For Exp FM (v/oct) and sync, the routing is controlled by the control module via the Track and Sync switches. The exp FM routing is handy for doing chords without having to worry about copying precision voltages. Everything is internally routed with high precision op amps.

MOD wave - Each oscillator controls what it sends as a modulation wave. Cascades has a jumper on the back to change between SIN and MOR outputs, while Brooks will always send SIN. Each oscillator then has an arrow next to each jack that receives a MOD wave signal. One twist on this is that Canyon can also be configured to send it's mix output as the MOD wave to OSC1, instead of receiving from OSC2. This is because the stepped voltage patterns that come from Canyon can be quite fun to use on an oscillator!

Cascades - Cascades is the fully featured thru-zero oscillator with an octave switch, voltage-controlled wave shaping (via Morph), amplitude modulation, along with a large variety of waveform ouptuts. A notable oddity is the inclusion of the COS output, which is great for some stereo effect. The idea being that Cascades works best as a main oscillator. But you can use either oscillator in any position in the overall system.

Brooks - Brooks is a smaller thru-zero 4hp basic VCO that has all the basic waveforms, FM control, sync, and Time Reverse which simply reverses the wave. While it is a fully capable oscillator it works best as a modulation oscillator in the COCO system.

Control Modules

The control modules do two things in the system, they control the routing for the exp FM and sync, and they add either upper (Valley) or lower (Canyon) harmonics. The switches control the routing of exp FM and sync between the oscillators, while only Canyon has any mod bus controls, which is available as a jumper on the back.

Valley - Valley is a wavefolder (aka adds upper harmonics) that offers some mixing at the input, along with controls over order (number of folds) and control over even or odd harmonics (more details). This is meant to be the opposite of the grit in Dirty Laundry and aims to be a nice clean wavefolder.

Canyon - Canyon is a sub-harmonics generator (aka add lower harmonics). You can think of it as a level-controlled clock divider where each knob controls the level of a sub-division (three is 1/3, five is 1/5, etc.). You can then either output just the odds or the evens via dedicated jacks or have a crossfade between the two.

The clock that is being sub-divided can be changed for the odds and evens sides independently so you can get some wonky cross modulation effects.

Notes: This is an exact hardware replica of the Mutable Instruments Veils 2020 module. After Later used the "hard-to-find" OPA1679 opamps, but we did switch the package from TSSOP to SOIC, to keep costs down. It is the same part/specs, just a different package.

Notes: Dirty Laundry is a destructive harmonic generator. The FOLD side can function as a standard Buchla-inspired wave folder but then extend into chaos when you engage the pre-fold PRESS section. The Press section creates all kinds of initial harmonics that really give the Fold section something to sink its teeth into. This results in a nice range of controlled harmonics from simple fold activity to anarchy.

The Press and Fold sections can function either as two parallel sections or as single serial unit. There are crossfaders between the sections and at the end of chain to help with blending between these two distinct sections. In development I mainly use it as a serial unit as I think it's most fun that way. But I found the need to control the mixes to get what I was after, so I added some extra patch points to make it parallel capable.

The module will work well with all waveforms (speech is fun) but I often stick with sine and triangle waves as I find them the most pleasing starting point. While most folders won't work well with square waves, the RES/DRIVE circuit will cause some rippling and make the FOLD much more interesting.

Notes: Dual three channel voltage controlled panning mixer

Mixer section

Channel 1 and Channel 2 are three channel mixers with potentiometers to control level of three different inputs for each channel. Each channel then has a potentiometer to control panning as well as CV control for panning and level control

Panning and VCA

The VC panners are equal loudness panning and the VCAs for each channel are linear response.

Built-in LFO

There is a built-in LFO that is normalled to the panning CV input of each channel. CH1 gets the standard LFO and CH2 gets an inverse, enabling alternating channel panning. The default is to use a TRI wave for the LFO, but there is a jumper on the back to switch it to SQU.

Notes: nRings

This is a new build of a micro version of Rings from Mutable Instruments. MicroRings, also called NanoRings, retains all the same functionality as a full-size Rings module.

Popple is an 8hp multimode stereo filter based on the Mutable Instruments Ripples V1 filter section. Popple maintains the buttery smoothness of Ripples filter while giving you two separate audio paths. The audio paths share a resonance, control, a frequency cutoff control, resonance CV input, and a v/oct cutoff CV input. Each channel then has it’s own cutoff CV input with attenuverters (which are normalled to a 2.5V signal).

Popple will also self-oscillate at high resonance settings, when coupled with the v/oct CV control, it can also act as a dual sine wave oscillator.

Notes: An 8HP version of Mutable Instruments Peaks that adds CV inputs and attenuverters for each of the four parameters and adds attenuverters for each of the outputs.

It can be an ADSR-style envelope generator, an LFO and a drum emulator.
