Thonk Turing Machine


Sorry, but English version of this review is unavailable due to significant size of text to be translated.

You can read about this great module suite here.

This is a fragment of 3-voice part made with Turing Machine and recorded to single track.

Cyborg Studio

Recently I found an interesting website named Cyborg Studio. Visitors can listen to preset patches of very wide range of synthesizers. Those patches was authomatically recorded with special robot, therefore it is not just selection of favourity patches but complete library.

ACXSynth MIDI2CV Firmware v5.5

New version of alternative firmware for ACXSynth MIDI2CV has been released.


Now you can limit polyphony in the range of 2—4 voices in Poly4 mode. Each press of the F1 key scrolls through three available values of this parameter. Available voices are mapped to corresponding number of CV/Gate outputs starting from CV1 / GATE1.

New version can be downloaded on the Project page

Galilean Moons announced new Eurorack module, Galilean Moons.
Galilean Moons is a dual amplitude transmutator. It transmutates the amplitude of incoming signals through the use of voltage controlled envelopes and VCAs. It is designed primarily to create voltage controlled percussive sounds when fed with a sound source (in particular, its sister module, Jupiter Storm), but can be used for all sorts of other tasks in your modular system as well as to generate typical synth sounds.

– Two voltage controlled digital functions (envelopes), each normalised to their own low-distortion linear, DC-coupled voltage controlled amplifier
– Each envelope offers percussive attack/decay, attack/sustain/release or looping (LFO) mode
– Envelopes can each be linear or exponential
– Enables a new noise output, “XOR”, if plugged into a Jupiter Storm behind the panel. (everything besides the XOR output works with or without a Jupiter Storm!)
– VCA inputs are normalised to the newly-enabled XOR and main (“I”) output of Jupiter Storm when nothing else is plugged in
– The envelopes and VCAs can be fully utilised elsewhere in your system by plugging into the corresponding function’s jacks
– Perfect for synthesizing voltage controlled percussion and other effects!

Module width: 18HP
Current consume: 88/65mA

ACXSynth MIDI2CV Firmware v5.4

New version of alternative firmware for ACXSynth MIDI2CV has been released..


1. Added full support for legato play in Mono and Poly1 modes
2. D2 key toggles legato retrigger
3. E2 key toggles velocity curve in Mono mode (Linear/exponential)
4. Trigger duration is extended to 1.28 ms.

New version can be downloaded on the Project page ACXSynth MIDI2CV polyphonic MIDI-CV converter

MIDI2CV_ThumbCanadian company, Electronics makes various modules for analog synthesizers. Almost every project is cross-platform and designed not only for Eurorack but also for 4U/5U formats. The model range includes noise-generating modules, sequencers, percussion, envelope generators and effects. This summer Hexinverter has released a new model: 4-voice polyphonic MIDI-CV converter.

MIDI-CV converter 5U module was designed by Alain Coupel of ACXSynth. In the year 2013 Stacy Gaudreau started to make his own version for Eurorack. Finally project became nice 8hp wide DIY module. Later I took a part in developing too by making new firmware.

Full kit (PCBs, components, front-panel and hardware) costs $120. (it’s not perfectly clear, USD or CAD, but rates are very close)
