MFB522 modded drum machine

video upload by Maffez Synthmods

"This is an ode of sorts to the MFB522, IMO one of the best 808 derivations. Small in size big in sound and sporting such great cymbals and hats. I documented the insides a little for folks who want to do modifications or need service info. Check this link for more details and sounds: https://maffez.com/?page_id=4095"

ambient talkie: ep 33 - NORNS standard vs shield

video upload by tworoundrobins

"due to popular demand, here are my personal thoughts on norns shield and norns standard. where do they differ? what are their similarities? etc...

i try to present my experience with both devices and hopefully this will give you a bit of a clue when deciding which one might be the right for you.

#norns #monome #ambient #tutorial

monome
if you want a standard norns you can get it direclty from directly from their site and this way support monome https://monome.org

build a norns shield
sadly, as of publishing this video, I believe that due to worldwide chip shortages monome is not offering any more norns shields. however, you can build one yourself.

DIY 4 voice arduino nano string synth (modified Jan Östman's Solina)

video upload by LAURI’S DIY CHAN

"HALT!! 🚨🚨🚨 THERE’S AN ERROR IN THE FILTER SCHEMATIC! The 10K resistor after the dual pot should be connected to the wiper of the pot! I’ve updated the schematic in the dropbox folder, please use it instead of the one in the video! Why can i never not mess up the schematics in these videos 😭😭😭

I built my own version of Jan Östman's solina string synth. It's a 4 voice polyphonic MIDI controlled arduino nano synth and a simple 12dB analog low pass filter. It's great for pads and weirder digital sounds, perfect for lofi music.

Arduino UNO R4 based digital VCO , it has Hard/Soft SYNC function.
Since the SYNC frequency is controlled by CV, SYNC sound can be created with fewer modules.

VG LINE TBX3Q3 - Acid Machine

video upload by VG-Line

"VG-Line TBX-3Q3 is a x0xb0x designed and crafted in Russia by Vyacheslav Grigoriev.
The x0xb0x is a complete clone of the legendary analog bass synthesizer, Roland TB-303, with a new, more powerful sequencer. This synthesizer, which led to the birth of the whole ACID subgenre of the techno music, has many implementations, but not all of them are 100% clones including identical analog part schematic and component set. Fortunately, The VG-Line TBX-3Q3 is one of them: a full clone, which uses even the same NOS transistor couples.The primary difference of VG-Line x0xb0xes is the use of specially picked transistors with β400 as were used in the original model by Roland. Only the 5th part from a 1000pcs batch can pass for the production of VG-Line unit."

Paia Oz Vintage Poly Synth Rare VGC Working

Pics of the inside below.

PAIA Oz synth from the 70s. It’s a cool, portable, battery powered synth organ with full sized keys, 5 octave selectable, trigger out, built in speaker and apparently used by DEVO. I soldered in a new battery holder as the old one looked flimsy and wasn’t making good contact. The ribbon controller is working but it’s more a gimmick and not a true pitch bender. All keys function and all functions work except I haven’t tested the trigger outs. This unit is pretty clean inside and out but it is a vintage DIY synth that’s rare so I’m selling as is and as described. Awesome piece to display in your collection and totally playable. I would imagine that adding a nine volt power supply would be extremely easy as well as adding an audio line out. This kind of begs to be modified into something more but I never got around to it."

Mutineer Synthesizer Demo - Tone Generator Span & Wavetable Editing

video upload by René Feuerlein

"In this demonstration of my synthesizer software programming project Mutineer, I am showing briefly showing a Tone Generator's capability to Span waveform over to the next Tone Generator, as in a Wavetable synth. Also I am briefly showing some of the wavetable waveform editing tools. I then add a lowpass resonance filter, a Chorus plus a Delay effect module, and later include a second Tone Generator, on which I also edit its waveform. The final result is a dreamy pad sound."

Het Concreet Scanner 2023

video upload by

"In November 2023, I joined the team at Het Concreet in Tilburg, The Netherlands for a week long residency.

Het Concreet is a Dutch sound collective dedicated to finding new sounds by experimenting with analog electronic devices, magnetic tape and acoustics. Their analogue ambitions are rooted in their studio space, where they seek to find new meanings of sound by working with techniques that have become largely obsolete in today’s world. Their main instrument is magnetic tape, so I collaborated with my own analogue gear.

Radio Concrète was a a 12-hour broadcasting marathon that explored radio as a compositional tool and included contributions from Margherita Brillada, Veerle Pennock, Clara Byom, Bas van Druten, Nele Möller, Marieke van de Ven, Sharon Stewart, and was hosted by Steph Byrne.

During my stay, I fell in love with the Elektor Formant, a vintage Dutch synth handmade by Jos van Ras. In addition I used my SOMA Ether, Lore Mill Keyed Mosstone and Make Noise Strega synth. At the end of the broadcast, I made an intimate performance for a live and dedicated audience in collaboration with Het Concreet. This is an excerpt from that show."

video upload by Ground Grown Circuits

via this auction

"This thing is great for dreamy evolving pads, drunk sounding horns, lofi surfing, and 80’s car chases.

The filter is modded to allow free playable control over cutoff and resonance, with a 2 pole/ 4 pole switch installed for more variety.
The chorus has been modded to allow adjustment of the rate, going into audio range for ringmod-like effects, adjustment of depth, and a true mix knob allowing for control between fully dry and fully wet.

There’s an external input, so you can run some audio signals in and override the noise (ext input level follows noise/filter envelope).

The internal battery has been replaced with a battery clip for no-solder battery swaps and a brand new battery has been installed.

All the tact switches have been replaced, so no annoying switch bounces while trying to program a sound.

The instrument is painted to match the green lettering in the programmer menu."
