Ghost in Translation 16 Inputs 16 Ouputs Teensy Eurorack


video upload by Ghost In Translation

"Using multiplexers for the inputs, the 2 ADCs of Teensy 4.0, shift registers for the outputs, I am able to sample 16 analog inputs at 44.1kHz each, and output 16 sigma-delta digital signals that can be filtered to produce analog signals up to 50Hz.

I am confident I can improve frequency and resolution of the outputs just with software, and will work on that later. For now this is enough for gates, triggers, CVs and LEDs.

This board is my platform for Eurorack modules, Motherboard 2. Everything will be available and documented on GitHub when I finalize a few more things.

New Sonic Sand Castles' Audio Enjoyer XR-1 Groovebox Sneak Peak


video upload by Sonic Sand Castles

"A test jam with the xr-1 groovebox"

xr-1 909 groove test


"Testing applying a 909-style groove/swing in varying amounts on the xr-1"

via Reddit 2 days ago:

"Hey all, this is a prototype of the xr-1, a digital drum machine, sampler, and synthesizer. It’s powered by the Teensy 4.1 microcontroller.

It’s a 909 style sequencer (a step can be off, on, or accented), with 16 banks, 16 patterns per bank, 16 tracks per pattern, and a max of 64 steps per track.

There are 4 performance modes (tap, mute, solo, ratchet) and a song arrangement mode.

It has stereo in/out (usb audio in the future). It has 5-pin DIN MIDI I/O, 4 pairs of CV/gate outputs (really 8x CV outs with 0V to +10V range).

A micro SD card is used to store/recall audio samples and project data. Samples can be mono RAW or stereo WAV files. Mono samples can be looped.

There are 16 sample voices available, and 4 voices which can be used as synthesizer voices.

I currently only have a simple 2-oscillator subtractive synthesizer right now. More will be added later.

It has a capacitive touch keyboard which is useful for assigning notes to steps, playing while jamming, performing with ratchets at various beat divisions.

Lots more details to come.

I will be demoing this at the Machina Bristronica festival in Bristol next week (flying all the way from the metro Detroit area, first time overseas). If you’re able to make it, come by booth (My business name is Audio Enjoyer) and say hi.

I will launch a signup page later this month and post here again so you can sign up for more info."

2023/06 - Norns Dub


video upload by Stereoping

"Summer tunes warmup. The Monome Norns running the beautiful 'RAINDROPS' script is sent through a DIY-PCB Juno-6 Chorus with Stereo-mod. The Norns is intentionally not temposynced and accompanied by a modded Alesis HR-16 which makes funny things when one of the Voice Eproms is removed. The HR-16's audio runs through a Yamaha CS-5 lowpass into a DIY Axoloti-based effects unit with lots of knobs for realtime tweaking Reverb/Delay and a little granulizer. The HR-16's midiclock drives a Volca Drum with Midi-Out-mod. The Volca's sequencer's Midinotes (incl. probablitiy and ratchetings) are converted by a little DIY Midi-box into the suitable notes for the Solin8 (starting at 3:10), a cheap 8bit-glitch teensy-based WAV-Drumsounds-Player with downsampling faders.

Clockwork Infinite Deep-space Rhythms - Great Conjunction, Wingie MKii & Dirtywave M8


video upload by Arman Bohn

"Development of the Great Conjunction hit a rough spot about a week ago when I changed microcontrollers from Promicro to Teensy 4.0. I had to rewire many pins on the board, but I think I’ve sorted most of it out, and I actually got MIDI running earlier this evening.

The M8 is primarily a mixer here, adding reverb and random delay. It’s also controlling the Wingie with a couple of LFO‘s set to vary the mix and decay rate of the resonators.

The Great Conjunction is the primary sound source. It’s producing FM sounds with three sequencers running.

This is my second M8 + Wingie jam with the Great Conjunction. This one’s a little more straightforward(?).

I’m still having some trouble locking the eight parameter knobs down when changing screens, so that’s on my to do list this week, along with sorting out a huge number of MIDI controls."

Eurorack MIDI Teensy 5x5 Interface Merger breakout


video upload by DeftAudio

"A quick overview of DIY MIDI interface kit for Eurorack based on Teensy 4.0 CPU.
Available here: https://www.tindie.com/products/defta..."



"Here is an Eurorack version of the popular Teensy 4.0 controller with 5x5 MIDI interface on TRS-A/B (selectable) ports as well as audio output.

This board is designed for Teensy4.0 and it's not compatible with other Teensy products. If you're looking for a similar board for Teensy4.1 or Teensy3.2, please, check other products in my store.

The board provides 5 input / 5 output functionality. This can be your 5x5 MIDI interface, merger, splitter, filter or whatever else you can imagine. This obviously requires programming the Arduino framework with Teensy extensions. I include basic firmware so, you can get USB MIDI running out of the box without any need to learn Arduino.

This TRS version is capable of setting a MIDI specification per port for TRS-A or TRS-B by moving jumper settings. This provides the flexibility to interface it with all vendors no matter the specification used.

You also get one Audio output (stereo) from Teensy Lo-Fi MSQ port. By default it's a sine generator programmed onto USB Port 6 and doesn't interfere with other 5x5 MIDI ports. It can be your clock out, trigger out or some advanced synth. Audio programming for Teensy is also straight forward.

All Teensy pins are available on extra pin headers. This allows easy expansion if you're planning to add extra LEDs, buttons, OLED display, in/outs etc... You can do that without soldering.

Package options:

PCB alone: This includes two PCBs(main and daughter) and aluminum front panel
Complete Electronics kit: Includes PCBs, front panel and all electronic (but Teensy4.0) - TRS connectors, optocouplers, headers, resistors, diodes. Check BOM list by the link.
Teensy microcontroller is not included with any purchase, you can buy it directly from the manufacturer: https://www.pjrc.com/store/

There are several options for providing a power:

From Teensy USB port
To be used with Eurorack 16pin power supply and sourcing 5V from eurorack (JP1 1-2)
To be used with Eurorack 10pin power supply, sourcing 12V from eurorack and doing onboard 5V conversion (JP1 2-3)
Board size and an enclosure choice: Eurorack size: 6HP, PCB Size: 10.8x5.4cm"

MicroDexed-Touch Nextgen Preview


video uploads by positionhigh



DIY Groovebox / Synth / Sequencer with 6 OP FM, VA and Sampling, based on a Teensy4.1

"These videos are very short feature demos that show what might become part of the microdexed project in the future.

This build will require a Teensy 4.1 Microcontroller and a graphical display with 320x240 pixel instead of the traditional 2x16 character text-display.

The screen also includes a resistive touch screen that will be concidered in the development. Other than that, we will keep the 2 encoders for interacting with the interface as it is.

This demo reel contains most of the new functions that are currently in development. Also you see the replacement of the Teensy Audio Adaptor by the PCM 5102 and the space for the external flash chip. Further, we will introduce some case improvements by screws going into threaded inserts. Case dimensions will be identical, as they were before.

Not everything of the new features is ready to use but at least you can get a glimpse of what is going to happen next.

Making demo reel videos is a lot harder than it looks. Maybe there will be one more at the end of 2022 and then the next will come up in 2023.

If you are involved in audio/microcontroller development as a passion, feel free to let us know if you like to participate and join the project development.

FusionLab ION Synthesizer


video upload by Toine Scholtz

"A little video demonstrating the Ion, a digitally controlled analog monosynth that I built a while ago. All the music in the video was created using the synth only (sequenced from and recorded into Ableton Live).

I started sketching the concept for the synth nearly 10 years before I began the build, but had a great deal to learn about analog and digital electronics before I was capable of actually building it. I arrived at the final design around mid-2020, began the build late 2020, and completed it a few months into 2021.

The synth is controlled by MIDI over USB. I used a PJRC Teensy 3.1 microcontroller and several DAC ICs to generate control voltages.

The Ion has 3 VCOs, each producing a slightly different selection of waveforms, and a noise source with its own state variable filter. Each VCO can produce a pulse width waveform, and each has a dedicated LFO to control PWM. There are two main resonant VC filters, each with continuously variable responses between LPF, HPF, BPF and notch. The filter configuration can be continuously faded between series and parallel.

The synth has a main VCA with dedicated envelope generator, and each VCF has a dedicated EG controlling cutoff frequency. A dedicated LFO can control the frequency of one or all three VCOs. Three other modulation sources, an EG and two LFOs, can be routed through the modulation matrix, a two channel matrix with 7 sources and 8 destinations available on each channel. Each VCO output can be also used as a mod source, as can the noise source. The matrix destinations include VCO pitch, VCF cutoffs, and AM of one of the VCOs and the main VCA.

The synth uses a Doepfer DIY synth board, which provides one of the VCOs, one of the VCFs and its envelope generator, the main VCA, the pitch modulation LFO, and the slew limiter used for the glide control. All the remaining modules are either completely discrete or make use of dedicated synth chips.

The design of VCO1 is adapted from Thomas Henry's astoundingly good VCO-1. The second VCF derives from Thomas Henry's beautiful VCF-1 design. VCO2 uses the AS3340 clone of the classic CEM chip. One of the mod source LFOs is based on a very elegant Ray Wilson design, and the other mod source LFO and envelope generator (as well as the main EG and the EG modulating the other VCF) are build using the fantastic modulation chips designed and supplied by Electric Druid. The noise source is also based on the Electric Druid noise generator IC.

In practice, the synth architecture is predominantly subtractive, but the mod matrix means it's also possible to do basic FM, although that's fairly limited by there being only two mod matrix channels (mod matrices are difficult and expensive to implement).

The synth cost about 5 months of spare time, more money than I have the courage to calculate, and some intense stress and frustration in getting it to work properly. Debugging hardware is much more difficult than debugging software.

It was an amazing journey of learning, and I'm one step closer to knowing how not to build a synth. It also gave me an even more acute and humbling appreciation of just how astounding is the work done by the synth electronics pioneers, and indeed contemporary designers. I stand, diminutive, on the shoulders of many giants.
