Teensy Audio Library on Raspberry Pi Pico 2 W

video upload by Ghost In Translation

"Raspberry Pi Pico 2 W is capable of running Teensy's Audio Library after some minor modifications.

Here I'm sending MIDI over USB to Pico which is running a 16 voices polyphonic synth sketch. The audio is then sent by I2S to a DAC (the same audio expander from my Motherboard).

There is some light cracking that is coming from the I2S library that I still need to take a look at, otherwise that chip is very capable."

How to calibrate the Motherboard by Ghost In Translation

video upload by Ghost In Translation

"The Motherboard features 16 inputs multiplexed over 2 ADC followed each by an amplification stage to adapt the inputs 0-5v range to Teensy's 0-3.3v.

Those 2 stages need to be calibrated to make sure the amplification's gain is right and that 5v in corresponds to 3.3v out.

With the following firmware and the help of 2 wires, easily adjust the gain by hearing a tone on each channel.

https://github.com/ghostintranslation...

The firmware connects an oscillator to IN1 and another to IN2. When the input goes up, so does the tone, up to a maximum reached at 3.3v on Teensy.

Connect one wire from 5v and to IN1, and one wire from GND to IN2. This will shut down the tone on the right channel and produce a tone in the left channel. Now turn the left trim potentiometer to adjust the gain until the tone reaches its maximum (meaning 5v corresponds to 3.3v).
Now wire from 5v to IN2 and from GND to IN1 and repeat the process.

Drone synth MIDI control

video upload by Ghost In Translation

"Upcoming firmware update 2.0.2 for Drone is bringing MIDI CC input via TRS and USB.

For this video I connected a UC33 MIDI DIN output to a TRS adapter to Drone's MIDI input on the back. I then demonstrate controlling all 6 settings from the controller as well as the module. Both can be used at the same time, they add up acting like offsets so there is no conflict between them.

Drone FM resonant filtered noise

video upload by Ghost In Translation

"This is Drone 2.0, 4 voices with individual 1v/oct pitch control, each voice has a sine oscillator and a resonant filtered white noise that can be mixed together and controlled by CV, the mix of the 4 voices can also be controlled by CV. Finally it is also possible to control the FM range of the 1v/oct inputs via CV, allowing nice FM at audio rates in place of 1v/oct sequences.

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.

Eurorack Drone Noise

video upload by Ghost In Translation

"I'm currently developing the second output of DRONE, it uses filtered noise at the source instead of sine/triangle like it is on the first output.

Around DRONE are KICK and MIXER. This is the new revision for MIXER, with 8 inputs over 2 channels. KICK is being triggered by an LFO.

KEYS prototype

video upload by Ghost In Translation

"This is the very first time I create a working prototype using multiple of my tactile keys.

Those who follow me on Instagram know by now that I've been working on making an entire tactile keyboard for quite some time. I tested many different designs for the keys, had a few failures, and recently it finally started to work.

The keys feature:
- very discreet
- 1 wire only per key
- pressure sensitive

The circuit to which the keys are connected is my current prototype of the MOTHERBOARD v2.0. It is based on Teensy 4.0.

My goal is to create a 32 keys keyboard...

"SYNTH is a modular FM synthesizer, based on eurorack physical format it has however no patch cables on the front but has rather midi and audio jacks in the back.

This product includes 1 front panel and the 2 necessary back pcb.

Colour option:
You have the choice of simple black (1 side) or bicolour (2 sides, just flip it) black/white or black/aluminum.

Note that the white is done with the silkscreen layer and the 'aluminum' is done with the copper layer so it is not perfectly flat as shown on pictures compare to the black that is the base board colour.

I took the photos on an angle on purpose to increase the imperfections, however they are not as strong when looking the panel straight."

Ghost In Translation DRONE & MIDI

video by Ghost In Translation

"Here is a demo of DRONE being controlled by MIDI, in this case I use an UC33 connected to a laptop and the laptop is sending MIDI over USB to DRONE.

DRONE is a drone synth base on MOTHERBOARD6. I've been working on adding MIDI CC callbacks to the MOTHERBOARDs and it's now easy to catch MIDI CC messages and do anything with them.

Additionally I've made a web editor that allows to set the MIDI CC values for each available param of a module just by connecting it by USB.

As a reminder, I've built 3 MOTHERBOARDs which are modular pcbs that I use to create all my modules. They are modular in the way that they allow to build all sorts of modules out of the same PCBs. They also come with a base code that abstracts the low level electronics components handling which makes it easy to code any module on top of it.
