These Korg35 are mounted on a circuit board that is recreating the HPF and LPF circuitry of a Korg MS-20.
Sorry. I don't sell anything.
Fell free to ask any questions.
Mom: We have synthesizers at home.
Synthesizers at home:

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 (catskullelectronics.com/products/famimimidi), 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 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 (www.supermidipak.com), 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.

Special thanks to Gotharman for sharing the gerber files of his now discontinued CS Filter module. With some patience, I got to reverse-engineer his surface mount PCB design and made it perfboard ready.
This module is not for sale.
The PDF file for this project will be made available on Eddy Bergman's Facebook page.
Feel free to ask any questions.

I could not find any information about this demo song on the web.
Music and effects: Moog Grandmother
Drums: AKAI XR-10
Feel free to ask any questions.
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.
Feel free to ask any questions or leave comments!
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.
Sorry again for the automatically generated ads. Enjoy!
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.
Synthesizer used:
Bass track: Ensoniq ESQ-1
Lead piano track: Roland XP-30
Special thanks to RAMCUR for his help and support in that project!
I tried to edit the Commodore 64 patches as close as I could to the original.
Because of the small number of keys, octave changes needed to be made in real time on the F1, F2, F4 and F8 buttons.
I used a C64c with a 6581 R4AR.
Make sure to watch my other 2 videos about this DIY Commodore keyboard:

As always, feel free to ask any questions!
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!
Drums: Kawai R50 - Hope you like trashy snares as much as me!
Here's a link to the original version of that legendary song:

Here the signal path:
Kenton Pro Solo MKII ► 3340 VCO ► MS-20 STYLE HPF ► 12AU7 DISTORTION ► ARP 4072 LPF ► VCA ► DTR-1 REVERB ► SOUND CARD.
(AD/AR ENVELOPE is modulating the VCA and YUSYNTH ENVELOPE is modulating the LPF & HPF.)
Note that the 12AU7 distortion really starts to shine when a polysynth is connected to it.
Feel free to ask any questions.
Once in a proper enclosure, I'll try to record something more substantial.
This version is the YUSYNTH version. You can visit his website to get the schematics:

I don't sell theses modules. Sorry!
No effects has been added.
Everything you hear in this video was played on these boxes, except for the drums. No effects where added.
The left one is a filter box that have a resonant Hipass Filter that goes into a 12AX7 valve and then in a resonant Lowpass Filter.
The right hand one have a 3340 Digisound circuit with a Eric G & Niklas Rönnberg Colored Noise module, a DTR-1 Reverb and a Boss TU-12 Precision tuner.
These are not for sale and I don't take orders. Sorry!
Feel free to ask any question!
Everything you hear here are the sounds of a Boss SYB-5 except for the percussions.
In order to have the best tracking for this track, I've sent MIDI notes to a Korg MS-20 going into the Boss SYB-5.
I used a 16' triangle waveform with a square shaped envelope (only sustain).
Note that the master volume of the Korg going into the Boss pedal made all the difference in terms of SPEED tracking (envelope follower).
Also note that other waveforms with more harmonics (sawtooth and pulse) were generating PITCH tracking errors.
In conclusion, when playing on a bass, one should play with the tone control on the bass (lowpass filtering) and use a compression pedal with a very compressed output. Finally, adjust the overall volume on the compression pedal for the best tracking when playing fast.
Feel free to ask me any questions!
Played on RAMCUR's custom "Minimoog in a suitcase".
Feel free to ask any questions.
4:05 Roland VP-9000 sampler + Akai S612 sampler.
Feel free to ask any questions.
Preset used:
- Lead: Wood - Flute / Bass: Synthe 2 - 8' : 0:00
- Lead: Voice - Alto / Bass: Synthe 1 - 16' : 1:06
- Lead: Synthe 2 - 8' / Bass: Synthe 2 - 8' & Synthe 1 - 16' : 2:13
- All together : 3:20
Only a slight reverb was added to the mix.
Feel free to ask any questions.
The top one is a filter box that have a resonant Hipass Filter that goes into a 12AX7 valve and then in a resonant Lowpass Filter.
The second box have a 3340 Digisound circuit with a Eric G & Niklas Rönnberg Colored Noise module, a DTR-1 Reverb and a Boss TU-12 Precision tuner.
In the weeks to come, I'll make a video to show the individual sounds these boxes can produce.
These are not for sale and I don't take orders. Sorry!
I don't know why people have no love for these little sound synthesizers.
Ok. They don't have that much headroom and are overall limited, but I think it's more than enough for a portable instrument that runs on 9 volts DC.
Stop hating. Just start doing better jams. In the end, it's not about the tool. It's how you use it. :D
In this second and last part of this series, I explain in detail how I made this keyboard out of a dead Commodore 8-bit computer and an Arturia MiniBrute keybed. At the end of the video, there are a few short clips of my friend playing the keyboard using different music programs.
This thing is neither a MIDI controller nor an Arduino / Raspberry Pi based design. It uses carbon contacts that act as switches and connect directly to the keyboard matrix inside a Commodore 64. Because of this, it works with ALL programs that use the C64 keys to play notes, allowing you to use a wide variety of original and sometimes rare music programs.

The words were all identified as a new step.
Then, a MIDI track was fed in the VP-9000 configured in step mode.
With every new note, the sampler automatically jumps to the next step / word.
Feel free to ask any questions.
Samples used:
- The "ahhhh" from the "mamaaa" of Queen's Bohemian Rhapsody.
- A single fart.
The backing synthesizer on this track is a Oberheim Matrix 6R.
Fell free to ask any questions.
The VP-9000 is fed by this classic Family Guy scene where Stewie is annoyingly calling his mom.
The sampler can automatically split the words of a sentence and jump to the next word when a new key is pressed.
On top of that, the sample time is preserved regardless of the pitch of the note being generated.
Feel free to ask any questions.
Sorry for the bad choice of songs. I was sampling from old CDs I had when I was a teenager.
I mostly wanted to show what kind of sounds you can get from making the Yamaha VSS-200 synthesizer run a a lower clock rate than it usually does.
If you do this mod, note that you need to be manipulating the sampling buttons when it is running at it's normal speed or else it will crash and you'll have to reboot the synth.
From Wikipedia:
"The Pot Keyboard Integrated Circuit (POKEY) is a digital I/O chip designed for the Atari 8-bit family of home computers and found in Atari arcade games of the 1980s. POKEY combines functions for sampling (ADC) potentiometers (such as game paddles) and scan matrices of switches (such as a computer keyboard) as well as sound generation. It produces four voices of distinctive square wave sound, either as clear tones or modified with a number of distortion settings. POKEY chips are used for audio in many arcade games including Centipede, Missile Command, Asteroids Deluxe, and Gauntlet. Some of Atari's arcade systems use multi-core versions with 2 or 4 POKEY chips in a single package for more sound voices. The Atari 7800 console allows a game cartridge to contain a POKEY, providing better sound than the system's audio chip. Only two licensed games make use of this: the ports of Ballblazer and Commando."
The MG-1 is a 2-VCO monophonic/polyphonic analog synth with a genuine 24dB/oct Moog filter, however the overall sound is thin. On the MG-1, the VCOs are referred to as 'Tone Generators'. It can produce sawtooth, square and pulse waveforms, and the oscillators are detunable and syncable. A simple ASR (attack, sustain, release) envelope called 'Contour' can be applied to both the amp and the filter. The LFO section provides triangle or square wave patterns as well as Sample-and-Hold. Additionally there is a simple Ring-Mod effect called 'Bell'.
Feel free to ask any questions.
Added some reverb and delay.
Feel free to ask any questions about this setup.
This synthesizer line are not toys. Back in the 80s, YAMAHA used their famous YM3812 FM chip, used in the original Sound Blaster and AdLib Music Synthesizer PC cards. and put it in keyboards for the home market.
These little keyboards are incredibly fun to play, and the FM slider based editing is a delight.
If, like me, you like to cruise in the memory lane, this thing will bring you back to your first PC that was equipped with a primitive 2 operator FM sound synthesizer card. We used to think it was amazing compared to the square-wave based pc speaker.
I modified my keyboard with MIDI IN using a Highly Liquid UMR2 module.
Sorry. I did not keep any schematics since this module is so simple to install. If you have a polyphonic keyboard that tracks the notes on the keybed using a matrix, but lacks MIDI capabilities, this is what you need.
I you are looking for a Highly Liquid UMR2 module, the creator of the board stopped doing them, but he was kind enough to make the design "open source". In other words, anyone can make them legally. Here's a trusted eBay seller who's still making/selling them:
