Live Music on DIY Synth


video upload by KellerDev

"I'm playing some stuff to test the Reverb and Delay that I am working on using the Daisy Seed. I really like how they sound, although you could tell That they are digital effects and not analog. But that's not really recorded well, the recording of the sound came out a bit bad"

DIY Voltage Controlled Oscillator


video upload by KellerDev

"This VCO has saw, triangular and square wave output. Simulation on falstad:
https://tinyurl.com/2kfswz4d It has puls width, linear and exponential frequency modulation.It is based on a Ray Wilson schematic, from MFOS: http://musicfromouterspace.com/analog...
RIP to Ray Wilson

Variable Clock Sequencer


video upload by KellerDev

"I changed the code for the sequencer to have more versatile random variable clock capabilities. I will upload the code to my patreon: https://www.patreon.com/kellerdev"

Simple ADSR Envelope (Not the Fastest Envelope On the West)


video upload by KellerDev

"I started this project with the intend to modify a schematic from Moritz Klein to have Release CV. Than I discovered I can extend what I was doing to make it have distinct Decay also, and not control the Decay with the Release Control like the Original. I also made a couple more changes to the schematic, including an option for Release accent trigger."

DIY eurorack synth jam


video upload by KellerDev

"I added a couple of things, icluding a stereo panning mixer from MFOS schematic. I'm trying to use a VCF as kickdrum but not really happy with the sound, I'm gonna try to build some 808 clones in the future."

Live playing on a DIY Modular Synth


video upload by KellerDev

"Live Jam to test the spring Reverb module
The module has Low and High Pass Filter, feedback and distortortion(soft clipping).

Sound Samples: https://soundcloud.com/kaloian-kraste...
The Sequencer, spring reverb and mixer are my design.
The VCF, VCA and ASR are from Moritz Klein: https://www.youtube.com/c/MoritzKlein0
The VCOs are from here: https://www.davidhaillant.com/simple-...
but I changed the temperature compensation to use NTC resistors"

Arduino DIY Sequencer for synthesizers with variableclock


video upload by KellerDev

"I implemented in the code a way of sequencing inspired by MFOS variclock sequncer and the intelligel metropolis, where you can set the amount of clock each step takes, before it goes to the next. That way you can longer melodies with fewer steps, and set repeating notes easier."

16 Step Arduino Sequencer - Project for Eurorack


video upload by KellerDev

"DIY 2x16 Step Sequencer for modular synthesizer. Controlled with an Arduino Nano and CD74HC595 shift registers. It has quantization and various modes of sequencing. It can put out a clock signal or use an external clock, to sync with other equipment

KellerDev Arduino DIY Modular Synthesizer


videos uploaded by KellerDev

Playlist:
1. DIY Modular Synthesizer Test
Playing arround with a melody on this diy modular synth
2. DIY 16 Step Sequencer
DIY 16 Step Sequencer for a modular Synthesizer. It uses a couple of shift registers and an Arduino Nano. The frequency for each step is read by the ADC of the arduino, then quantized and played back through the PWM as CV. The v/oct scale is set by an opamp
3. Arduino DIY synth, sequencer and drum machine
This is a DIY synthesizer made with the mozzi library and Arduino Nano. It uses 4 multiplexers CD4051 and three decade counters 4017. Sound samples : https://soundcloud.com/kaloian-kraste...
4. DIY analog Synth - Arduino Nano PWM CV output
Setup for Control Voltage output for a DIY analog synthesizer, using the PWM from arduino. Adjusting it to align with the 1v/octave standard.Most modules so far are from Moritz Klein, including the Diode Ladder Filter. Here's a sound example : https://soundcloud.com/kaloian-kraste...
