MIDI Goblin 1.5 and Polyphonic Synth Announcement

video upload by MIDI GOBLIN

"Hi everyone. In this video...I announce MIDI Goblin 1.5!

It's MIDI Goblin - but with audio output and a polyphonic synthesizer firmware I've been working on for the past few months called Pingler.

Owners of the original MIDI Goblin will be pleased to hear that they can upgrade their Goblin to 1.5 at home!

pre-sales for MIDI Goblin 1.5 will begin April 30th 2025 and a VERY limited number of them will be available if our neighbors to the south go through with their tariff 'plans'

Pics of the inside below.

"One of the classic modules of all time, and in its original R.A. Moog incarnation, dating from January (or possibly November) 1969. This example has a 'Bypass' switch mod. This looks very much like a factory modification requested by the original buyer - the style of switch and the black Dymo label seem exactly what Moog would have used at the time. Bought by the current owner in 1999, with light use in a smoke-free home studio. Working well. At some time in the past this actual module was sent to Paul Schreiber to help him design the MOTM 940, and Paul calibrated it to self-oscillate correctly. Situated in the USA but light enough to send economically worldwide."

"Four classic mid-seventies modules: one 921A Oscillator Driver, and three 921B Oscillators. Complete with an International Power switchable power supply (now more commonly badged Power One) and a wiring harness / loom wired for five modules - the four 921s here, and a fifth module - until now, the 904 in the previous lot. ***This will need encasing***, and of course the modules will need to go in a simple case or an existing cabinet. In very nice cosmetic condition, and working well. Bought by the current owner in 2003, and since lightly used in a non-smoking home studio. The power supply has a standard IEC mains socket and fused switch with power light. The fuse will need to be changed if the voltage is switched from USA, where it is currently located."

VEMIA is Peter Forrest's auction house. He is the author of The A-Z of Analogue Synthesizer Books.

"SCHOBER TUNESMITH (new start price to allow bids from outside the seller's tax region) Very rare monophonic transistor synth, single oscillator, circa 1968, sold as a kit or pre-assembled. The voice switch activates different static filters, providing 6 markedly different tones from bright sawtooth to mellow triangle. This short video [posted here] of the same model clearly shows the sounds ---- I read that the keyboard is a Pratt-Reed that uses series resistance rather than a matrix. This model for auction has clear strong sound with almost no hum whatsoever. The main problem is the tuning is way off, and some notes glitch a little. Not difficult to repair, I would think. Also the vibrato is not working, probably just a bad resistor, should be easy to fix. Body is solid and in good condition for a 57-year old instrument, so it hasn't been knocked about. Keyboard and control panel are very clean, almost no scratches. Mainly home or studio use, probably. The three tools contained inside the lid are a complete mystery, which may be solved once you look inside the unit! While this is offered as a 'project' the encouraging thing is how bright and clear it sounds, and once tuning and vibrato are fixed, you have a very playable instrument similar to a Clavioline. It's a worthwhile project, I would say. Power is 105-120V 50/60 cycles, with a 2-pin US-style mains plug. I've given it a very low start price. SHIPPING: This Tunesmith is located in Japan, and weighs (packed) approximately 7kg. Discounted shipping to UK/Europe/USA will be £30 surface, £80 air. For other countries, please enquire."

Emotional Waste - ambient electronica - Vermona Perfourmer, Moog Muse, Polybrute12, Summit & Piano

video upload by copenhagennoiselab

"I was connecting stuff in my temporary home office studio setup yesterday and had brought out my Vermona Perfourmer (mk1) from storage. So while setting it up I recorded a simple 4 bar thing as midi and let it drive the Perfourmer synthesizer. I had it running for a few hours while I was connecting midi and audio for the other synths I have in the home office and I never got bored of it. So today I decided to quickly add some piano and other synths to it to see if I could make it into something more... I dunno if the last part was succesful though, but at least I got it documented...

The main synth is the Vermona Perfourmer playing a chord structure thing. The second synth that appears is a lead from the Expressive E Osmose followed by a bass from the Novation Summit and another soft lead from the Moog Muse. Then a chord with some morphee filtering from the Arturia Polybrute 12 before the Piano comes in. (Just another piano improvisation more or less). At the end I start to mess up the Vermona thing and I also added a Drummer track in Apple Logic Pro."

Tiptop Audio Polyphonic Modular System - In The Studio

video upload by Tiptop Audio

"To celebrate the release of the first set of Polyphonic modules, the Vortex6, Octogain, Octostages, Octopus, Octovert, and the Polytip Patch Cables—we invited Simone Miceli to join Piero Fragola in his home studio in Florence, Italy, to compose a song. This piece demonstrates how a violin, vocals, and these new Eurorack modules work together to create music.

Except for the vocals and violin, which were recorded separately, all synth voices were captured in a single take from the system in the video. The leading sound in the track is the Vortex6, with all six voices gliding seamlessly between notes.

In a polyphonic synthesizer, we know that the key building blocks like oscillators, filters, and LFOs are hard-wired under the hood of the synth. In modular poly, we open up all the possibilities that modular synthesis provides--IN POLY!
Welcome to the future."

New Kaleidoscope Mini Desktop Synth Incoming

video uploads by Vadjuse

This one was spotted and sent in via Meska.

Playlist:

1. Teaser. Kaleidoscope mimics a blip blop machine.

2. Teaser 2. Kaleidoscope mimics a boom-tysch machine.

Some raw drums exploration.

3. Kaleidoscope. Reload Zone. Post-Apocalyptic Ambient.

In this video I experiment with the generative sequencer of the Kaleidoscope.

The pattern is relatively simple:

1. VCA1 (which means it belongs to track 1) works in a cyclic mode, i.e. it restarts itself.
2. With its end it starts VCA2 (which means it belongs to track 2).

3. VCA2 modulates the period of VCA1, and VCA1 modulates the period of VCA2 (fm synthesis at the rhythm level). Because of this, the length of the pattern wanders a little and creates a pleasant dynamic.

4. Modulation envelope 1 (MODENV1) also works in a cyclic mode and restarts itself, but with a completely different period than the VCA1. This creates an additional rhythmic layer in the overall sound.

5. MODENV1 modulates the wavefolder level of track 2.

6. Track 1 modulates the frequency of track 2, and track 2 modulates the frequency of track 1.

7. All this is seasoned with a comb-filter in delay mode, which creates another rhythmic layer.

The presets for track 1 and track 2 used in this video can be downloaded and loaded into your Kaleidoscope. After the release of the synthesizer, I will publish these and other patches so that you can play with them and modify them yourself.

4. Kaleidoscope. Hypnotic Resonance

On the home stretch, Kaleidoscope will be released soon.
On the video new PCB version with
typeC plug
4 channel DAC
improved encoder filtering section

In this video I experiment with a relatively simple patch.
The cyclic modulator changes the symmetry of the triangle wave. From a symmetrical triangle to a saw. This changes the spectrum.

As a result, the filter resonance periodically amplifies individual harmonics. The filter frequency is modulated by the volume envelope.

Since the filter frequencies can be precisely tuned to the MIDI note frequencies, the modulation results in all the natural harmonics of only one octave being cycled through. This makes it seem like there is some kind of sequence in the patch, although in fact there is none - it's just a native process.

At high resonance values, the signal is overloaded in the filter feedback circuit.

The signal is also additionally overloaded in the overdrive block.

All this gets into the comb filter, which works as an echo.

I've been glued to this patch for about a day, which makes me a little sick of it, but I still like it.

NAMM 2025: Donner L1 Synthesizer w/ Removable Keyboard Controller

video upload by sonicstate

You might remember the Donner L1 from this post. New NAMM video above followed by pics and additional details below. Note the keyboard is actually separate from the control section; you can have either the full keyboard or desktop.

"At the latest NAMM show, we caught up with Gabriel from *Donner*, who introduced us to the *L1 Synthesizer*, a new unit that merges homage to classic designs with modern flair. While it shares a visual nod to the legendary SH-101, Donner was keen on establishing its unique identity. The L1 includes additional sound sources, most notably a warm triangle wave. The sub-oscillator offers three variations: a pulse wave an octave down, one two octaves down, and a variable pulse wave.

A standout feature was the external input capability, allowing you to process a guitar, other synths, or even vocals through the synth's filters and envelopes. An intriguing LFO design pushes into the audio rate, enabling FM modulation. The L1's onboard sequencer supports 64 steps per slot and allows you to store sequence presets--a handy addition for live settings. The L1 should be available Autumn 2025."

Belgian Magazine Article Featuring Mario Mathy

This one is in via Jos who had the following to say followed by an English translation of the article.

"Years ago, I sent you information about Mario Mathy (I think 2019). You published it on your blog. [you can find it in previous posts featuring Mario Mathy here] Afterward, Mario Mathy's 'Jumping Dance' went viral and achieved cult status.

Since your blog has become the most comprehensive and important documented synthesizer resource online, the attached article should also be saved for future history. It would be cool if you could share it with the rest of the synthesizer community. I translated it from Dutch to English using Google Translate.

Notice in the picture below the article that the photo was taken during the period when Mario endorsed Korg.

All I can see in the picture is Korg equipment. The song 'Love Dreams' is from his first album.

I expect most of the songs from his first album ‘Hello This is Mario Mathy’ were created using Korg synthesizers (in contrary to what you would expect from the album cover showing only casio).

After his first album, the single 'Jumping Dance' was released in Belgium. 'Jumping Dance' was from his second album, 'Music-Land'.

On his second album, you can hear a noticeable difference in his sound.

This likely resulted from switching from Korg to Casio synthesizers.

Mario was my piano teacher when I was about 15 years old."

You can check out Mario Mathy's releases on Discogs here.

The following is the tranlation of the article pictured in this post.
