DIY Minimoog Inspired Synth | A Teensy Powered Tribute

video upload by Moby Pixel

"In this video, we’re building a Teensy-powered synth inspired by the iconic Minimoog Model D, and exploring what made the original design so legendary. We’ll walk through all-the-things: oscillators, mixer, filter, envelopes, hidden features, presets, the Teensy’s USB audio setup, and how Bob Moog’s Minimoog helped shape modern subtractive synthesis.

This is my biggest project to date, and I couldn’t be happier with how it turned out! The Teensy 4.1’s built-in USB audio is sending power, MIDI, and audio over a single cable. What a time to be alive, haha! All code and build files are available on GitHub if you want to make your own. Cheers!

Progress on the Teensy TDM synth

video upload by Craig Barnes

"Latest update of the Teensy 4.1 based audio library synth. I've ditched the hardware envelopes because they lacked real-time control and only changed on a fresh key press, so now the Electric Druid Envgen8c chips are back in their sockets on envelope duty. I've opted for log envelopes although I think the AS2164 has a lin/log converter, I need to check."

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.
