The Threetom Modular MIXING FLASK is a utility mix

The Threetom Modular MIXING FLASK is a utility mixer offering mix-bus limiting and a cornucopia of indicator lights integrated behind a unique chemical lab-inspired front panel. Buy it now from Thonk, link in bio!

MIXING FLASK was designed as a solution to three main gripes when it comes to conventional utility mixers:

- Mixing too hot is too easy, leading to hard clipping on the mix-bus. And even when there’s an indicator light to warn you when this is happening, there are no features to actively prevent it.
- Utility mixers usually only offer unity gain, so when you have a weak input signal, you’re out of luck
- They’re nauseatingly boring!

Provides solutions to these annoyances in the following ways:

- By implementing a soft-clipping limiting circuit on the mix-bus (inspired by DOPPIO). The highest setting prevents the mix-bus from hard clipping altogether in favour of warm saturation.
- All inputs have a gain of +6dB allowing you to better equalize between volumes while maintaining a hot mix-bus output
- The myriad of indicator lights and front-panel graphics make you feel like a mad scientist in your own modular chemical lab. We bet you won’t find another utility mixer that makes mixing more exciting than MIXING FLASK!

Available at Thonk now, link in bio!

OUR NOVEMBER SAVINGS START WITH DISCOUNTS ON LOOSE

OUR NOVEMBER SAVINGS START WITH DISCOUNTS ON LOOSE PARTS

As we posted on our mailing list yesterday, we’re splitting our November price savings into two events.

This week we have set up the first event, live discounts on all our loose DIY parts, so if loose parts are your main interest then right now is the right time to get an order shipped.

Next week we’ll launch our second event with deals on a wide range of full kits and the other products we sell. We’ll tell mailing list members first when it’s live. The full kit deals won’t be announced until next week, once we know what stock is left. Orders cannot be combined to save on shipping.

If you want to wait until next week when the other deals go live then all these loose part deals will still be live then too. These deals are only available while we have stock and only from direct orders on thonk.co.uk. We can’t hold orders and bundle them with separate orders next week.

The classic Modular Synth tome is back in stock! L

The classic Modular Synth tome is back in stock! Limited run and a great Xmas gift for that modular obsessive in your life. Link in bio.

“Since it’s first edition in 1972, Electronic Music: Systems, Techniques and Controls has been acknowledged as the definitive text on modular synthesis. In today’s musical community analogue techniques have made a resurgence among many musicians and composers.

The idea of a republication has been in the works for many years and the timing of doing it now just made sense. I am very grateful to Jason Nolan, Ann Ludbrook and the team at Toronto Metropolitan University who saw the importance of this endeavour as well as taking on the task of bringing this book back to life. I am so appreciative of their attention to preserving the quality of the book and respecting its content. I know that this project would have meant a lot to Allen, specifically in knowing that his techniques and teachings are continuing to influence the future of electronic music.” – Pat Strange

“Allen Strange’s book was ahead of it’s time and it’s time is now!” – Suzanne Ciani

“Allen’s book quickly became my bible, I have used it in my teachings for thirty years” – Eric Chasalow

“When I first stumbled upon this book at the university library as a student, I felt like I had discovered a secret treasure. Opening the cover felt like opening the door to a mysterious new world. I’m delighted that a new generation can again share this experience of excitement and discovery!” – Carla Scarletti

We have a small batch of DIY kits of Solid Felt, a desktop stereo analog filter with onboard modulation from Herbs and Stones.

Link in bio!

From subtle timbral variation to an all-encompassing sonic treatment, Solid Felt can be used in multiple ways to embellish or vandalize your sound bouquet.

Its patchable design allows the analog filters to be used in stereo, dual mono, or a number of other experimental applications. The two filters, A and B, can operate in lowpass, bandpass, or highpass modes, and both filters feature resonance for squelchy sweeps or pinged self-oscillation purposes. Both cutoff frequency and filter mode can be CV controlled, either by self-patching using the onboard modulators or via external CV signals from eg. Eurorack modular.

We have these two neat little utilities in stock today at Thonk from Cubusynth.

4TRG has 4 independent Random Gate skippers with probability knob per channel. The First channel can turn into a Clock generator when no cable is inserted into the Gate input. The Output is then Normalized to the other channels (2-4). It can also create “ratcheting” gates. The knob determines the Ratcheting speed.

4DECAY offers 4 Envelopes for percussive and plucky sounds. The Gate inputs are normalised to the Jack below, which lets you use the same Gate signal for 2, 3 or all 4 channels at the same time.

@stazma did a great demo of the DivKid TRACE. Check out the link in our bio to watch the full video of this collaboration between DivKid and Vostok Instruments.

Trace is a four-channel Interpolating Scanner. Introduced by Jurgen Haible in 1994 and later improved by Donald Tillman in 1999, the Interpolating Scanning circuit is a hybrid between a signal selector and a crossfader.

The circuit morphs between the inputs, fading from one to the next as the voltage control rises. The Trace version of this classic circuit comes with a custom, fine-tuned slope response that prioritizes a smooth transition between the inputs, providing interesting middle points between the channels and improving its behavior when controlled by external CV signals.

Trace is a four-channel Interpolating Scanner created by VOSTOK Instruments in collaboration with Ben Wilson “DivKid”.

Introduced by Jurgen Haible in 1994 and later improved by Donald Tillman in 1999, the Interpolating Scanning circuit is a hybrid between a signal selector and a crossfader.

The circuit morphs between the inputs, fading from one to the next as the voltage control rises. The Trace version of this classic circuit comes with a custom, fine-tuned slope response that prioritizes a smooth transition between the inputs, providing interesting middle points between the channels and improving its behavior when controlled by external CV signals.

Following Ben’s unique vision and module design, Trace unifies the compact form that characterizes his modules with Vostok’s hardware and aesthetics.

From waveform morphing and CV-controlled transitions, to audio-rate scanning. Trace brings a new horizon of patching possibilities to any system.

GLOOP is an experimental Eurorack looper and the full DIY kit is in stock at Thonk now. Link in bio.

GLOOP has the ability to playback recorded loops with 4 simultaneous play heads.

Each play head can be at a different part of the loop, playing at a different speed/pitch, direction and volume. Each play head can also be playing a different area, or sub-loop of the main loop. Gloops excels at building layered textured tones and creating granular style loops. There are 4 x CV inputs which can be assigned to modulate the speed, position or volume of individual or multiple playheads. There are also a number of built in effects including delay, reverb and bitcrush to further sculpt Gloop audio.
