The Nintendo NES MIDI Synthesizer

video upload by MrCaliforniaD

"I built this custom Nintendo NES MIDI synthesizer using a real Nintendo (Model NES-001) and a Famimimidi NES cartridge.

The Famimimidi NES cartridge is an incredibly well developped product that lets you control a Nintendo sound chip via MIDI IN. It's rare that such a product is released to the public in such a stable and complete state.

The cartridge is available for purchase (, but it seems to be out of stock at the moment.

The challenge for this project was to fit everything in a 1U rackmount enclosure.

This project is a one-off, and I don't intend to build more of them. Not for sale. Sorry!"

The Super Nintendo Synthesizer with MIDI

video upload by MrCaliforniaD

"I built this custom Super Nintendo MIDI synthesizer using a real Super Nintendo (SNS-001) and a Super Midi Pak cartridge.

The Super Midi Pak cartridge is an incredibly well developped product that lets you control a Super Nintendo sound card via a MIDI I/O cartridge. It's rare that such a product is released to the public in such a stable and complete state.

The cartridge is available for purchase (, but there's a long waiting list for it.

The challenge for this project was to fit everything in a 1U rackmount enclosure. One of the things that had to be modified was the cartridge port angle, so that it sits parallel to the board instead of perpendicular.

The pitch adjustement knob uses a LTC1799 Precision Oscillator instead of the original crystal assigned to the audio chips. Credit for this mod goes to Sam from Look Mum No Computer. Go check out his channel if you haven't already.

This project is a one-off, and I don't intend to build more of them. Sorry!"

Analog Filter Comparison - Korg 35 / ARP 4072 / Moog 4-Pole Ladder

video by MrCaliforniaD

Music: Lead track from Pitfall II
Oscillator: 70% Pulse of a Korg MS-20

Korg 35 filter : Korg MS-20 (early revision)
A.R.P. 4072 filter : A.R.P. Explorer I
Moog 4-Pole Ladder Filter : Moog Minimoog Model D

"It is virtually impossible to do a fully comprehensive video of all the aspects of a filter. This video is not trying to achieve this goal, but to document just some of these variations.

All filters do not lose or add gain over frequencies the same way, and even though I tried to normalize the gain as closely as I could to one another, there are always differences, especially at the early stage of filter oscillation. The type of speakers you're listening this video with will also make a huge difference in the perceived tone."

I'll Be There (Jackson 5) - Arp Explorer I Analog Synthesizer From 1974

video by MrCaliforniaD

"I made this video back in 2013. I then tried to upload it on YouTube, but it got rejected because of copyrights infringements.

Now that they can monetize it all they want, maybe I can share it with the world.

This song was originally recorded in 1970. This is what it could have sounded like if all the tracks were recorded on a Arp Explorer I Monophonic Analog Synthesizer from 1974.

Polyphony was achieved by adding monophonic tracks on top of each other but it was kept pretty minimalistic."

Synthesizer CV to X-Y Recorder Visual Art

video by MrCaliforniaD

"In this video, a 2 channel MIDI to CV converter is controlling a X-Y Recorder.

This technique is pretty straight forward. The X-Y Recorder is listening to voltages signals on its two X-Y axis. The voltages are taken straight out of the MIDI to CV converter's two channels.

I used a 2 track song. One melody moves the X axis on the plotter and the other melody moves the Y axis. The pen is drawing the resulting mix of theses to axis interfering with each other.

Special thanks to RAMCUR for his help and support in that project!"

Fairlight Intro Cover on the Commodore Music Maker Deluxe

video by MrCaliforniaD

"In this video, I've re-recorded the famous hack intro from Fairlight.

I tried to edit the Commodore 64 patches as close as I could to the original.

I used a C64c with a 6581 R4-AR."

King's Quest VI - The Isle Of Wonder (PC) - Played on a Korg DW-6000

video by MrCaliforniaD

"Aliasing digital wavefoms festival."

Saturday, November 21, 2020




This obscure demo might have been produced at some point by the E-MU team when the SE upgrade was released, but there's no mention of it on the Internet.

Therefore, I am sharing it with the world.

Special thanks to Jay Boy for helping me find my Emax and to Olivier Van Tassel for selling it to me!"

Synthesizer Build part-21: ARP2600 LOWPASS FILTER (4072).

The best sounding filter of any I built so far! With verified stripboard layout.

A word of warning right at the start; this is an advanced project, not for beginners. You need to know your electronics and you also need to have a good multi channel oscilloscope.

The Commodore Music Maker Deluxe Improvised Jam

Published on Dec 26, 2019 MrCaliforniaD

"First off, sorry for the occasional clipping of the sound console.

This is my friend Jay-Boi playing with the Music Maker Deluxe in a very basic but effective musical setup.

The Commodore controller is connected directly on the keyboard matrix of a Commodore 64c (SID 8580). The sound used is a 3 voice sawtooth waveform with adjustable LFO amount and filter amount using the 2 potentiometers on the side.

The audio out of the C64c is going inside a DIY MS-20 like filter box that receives it's modulation from the a Korg MS-20. The output of the filter box goes to a first track. The Korg MS-20 is connected to a second track.
