  • Prototype of a Chainable Eurorack Sequencer

    Support me on Patreon and make more videos possible: https://patreon.com/Polykit

    At last there is progress on my 8-Step Eurorack Sequencer! This Arduino based device not only got plenty of CV options but multiple units can be chained together for longer sequences! In this video I take a look at the fully working prototype and talk about the technical details. Full DIY kits and PCBs of the module will be available later on this year. Have fun!

    First demo of the step sequencer: https://youtube.com/shorts/KIN2WQEZNrk

  • Versatile building block - Op-amps in DIY Synthesizers

    Support me on Patreon and make more videos possible: https://patreon.com/Polykit

    This is another videos in my basic electronic component series. Today I'm going to take a closer look at op-amps or operational amplifiers. Op-amps are one of the most important building blocks in analog, DIY synthesizers and have all sorts of applications. Enjoy!

  • First demo of my Eurorack Sequencer

    This is a first demo of my Eurorack Sequencer. The second sequencer is manipulating the first one via CV, all the modules are part of my DIY Eurorack line-up. The sequencer will be available later on this year when the software is finished.

    Key specs:

    • 8-step sequencer
    • Open-source software
    • Arduino based
    • CV for rate, step count and gate length
    • Clock in/out
    • Gate output
    • Reset input
    • Glide control
    • Extension port
    • Multiple units can be chained for longer sequences

    • Building a simple Eurorack case

      In this video I look into building a simple Eurorack case with two rows of 104 HP. I use aluminium profiles like in the Doepfer casings to keep the modules in place. Let's get started!

    • Progress on the DIY polysynth software

      I made some progress on the software side of the analog 8-voice DIY polysynth that I'm going to discuss in this video. Have fun!

      Support me on Patreon to make this and other projects possible: https://patreon.com/Polykit

      Check out my Eurorack DIY kits: https://store.polykit.rocks

      Key features of the synth:

      • 8 independent analog voices
        • one VCO/VCA/ADSR per voice
        • ADSR can modulate filter frequency and resonance
        • multi-mode filter (8 different filter responses)
        • fully programmable
          • store/restore patches
          • programmable control/input section
          • 16x2 LCD
          • MIDI input
          • If you are interested in the build process make sure to check out the playlist: https://www.youtube.com/watch?v=3vlqWBn1umI&list=PLUKLEU8jmlbHH4_13YZM0MI6ez4gYQPfy

          • How Digitally Controlled Oscillators Work

            In this video I look into digitally controlled oscillators (DCOs), how the work and which problems need to be solved.

            The video on the classic analog oscillator design can be found here: https://www.youtube.com/watch?v=JJIUcveN_YU

            Schematics and software for the DCO can be found here: https://github.com/polykit/pico-dco

          • How vintage synth oscillators work

            In this video I look into a classic oscillator design like in the 70s. We will see why it got replaced by integrated circuits, DCOs and other digitally controlled oscillators.
