Reader Nick Culbertson shared this video, demonstrating how to make a simple, lo-fi $1 synth.
It’s based on a 555 timer module, which is the heart of the classic Atari Punk Console DIY noisemaker project.
Culbertson includes the mistakes he made in his video, so viewers can hopefully avoid making the same ones.
Video Summary:
“In this video, we’re building the cheapest and easiest synth ever using a 555 Timer module! It’s raw, lo-fi, and as you’ll see, not everything went according to plan.
From breadboarding the circuit to hacking the built-in trim pots, we’ll explore how to turn this simple chip into a tiny synth. Along the way, we’ll deal with torn traces, questionable soldering, and some happy accidents.
If you’re into DIY electronics, synths, or just making weird sounds then this one’s for you!”
Tubbutec shared this video overview of their Brainstep Controller, an expander for their Brainstep ‘sequencing brain’ for Eurorack modular systems.
While it is possible to change Brainstep’s envelope and LFO parameters using the menu, the Brainstep Controller makes it possible to control these parameters with tactile immediacy.
The 25 sliders enable you control most accent, ADSR and LFO parameters. Additionaly, the glide time can be controlled.
The Brainstep Controller is available now for € 300.
Squarp Instruments has introduced the xp32, an output expander designed to expand the creative power of the Squarp Hermod+ sequencer.
With 32 additional assignable CV or Gate outputs, the xp32 transforms Hermod+ into a 16-track CV/Gate powerhouse, an expansive MIDI/USB-to-CV interface, and a versatile preset manager.
HERMOD+OS 2.0
To support XP32, Squarp has also introduced Hermod+OS 2.0, a major firmware upgrade.
The update offers a variety of new creative tools and improvements, even for users without the XP32:
Internal Modulation – Each track now includes four independent MOD lanes that can be step-sequenced, recorded or generated and routed through the mod matrix.
Advanced Data Editing & Randomization – Users can now display, edit, and randomize any type of track data including MOD, Aftertouch, Velocity, and more.
Refined Workflow & Enhanced Flexibility – The update also includes performance improvements, UI refinements, and additional features designed to make sequencing more intuitive.
Added CV IN Detection – (when Hermod+ is recording, the CV IN modulation will be recorded only if a change is detected, in order to save memory space).
Seamless Integration
Setting up the xp32 is simple. By connecting the included expander ribbon cable to the back of Hermod+, the xp32 integrates automatically, no configuration required. Hermod+ recognizes the xp32, making all 32 additional outputs immediately available.
