And one from 2-Minute Warning:

The Key - 4-Minute Jam (TempoKEY K32 Play + Taiga + DFAM)

video upload by 2-Minute Warning

"This video is a little different for two reasons!

First, it's the first time I'm featuring an instrument kindly provided by a manufacturer. Synido sent me the TempoKEY K32 Play to explore in my own workflow and share my honest impressions.

They didn't ask for a scripted review, so I simply approached it the same way I approach every other instrument on this channel: by making music with it.

Secondly... this is exceptionally a 4-minute jam!

Think of it as two consecutive 2-minute performances before I take a short summer break. 😊

Rather than trying to showcase every feature of the K32 as a MIDI controller (Bluetooth MIDI, battery power, USB/MIDI connectivity, pads, knobs, etc.), I wanted to focus on what intrigued me the most: its built-in General MIDI sound engine.

For this performance, the Hapax sequences the entire setup. The Taiga handles the bass, the DFAM takes care of the analog drums (synchronized by the Hapax), while the K32 Play provides everything else: guitars, strings, bells, plucks, additional drum sounds… and occasionally runs through the Eventide H90 for a bit of extra space and texture.

As always, the musical performance itself was recorded in a single take. Mixing/mastering was done afterwards in Ableton Live, but the performance you hear is exactly as it happened.

A sincere thank you to Synido. Without their message, this musical experiment probably wouldn't have happened."

VIVALDI - Autumn Part 1 on SIX (5) ARP Odysseys

video upload by Richard Payne

"Been having a pop at Autumn Part 1 these last few days and this take I recorded (take 111!) has come out slightly 'dystopian' sounding and synthy. Have pushed the filters a bit more. There’s a bit of overdrive in places and some wobbly 'pitchy' stuff happening. But lots going on and lots of things to remember to do. Or not to do. This take here was only the 4th time I’d made it to the end, and the first and only without completely ballsing it up.

Odyssey #3 was briefly back in the fold last week and was ably handling the sub bass part all on it’s own, but it started going wrong again and has been taken back to the repair shop. So to cover that part here, I’m bringing in and out oscillator 2 on Odyssey #6, which is set to a square wave an octave down. I’d say a good 80 of those earlier takes that I mucked up were ruined by me forgetting to do this, or doing it badly, or at completely the wrong time. There’s a 'high jeopardy' patch change happening on Odyssey #1 too which I liked to get wrong, transitioning from a short filtery harmony part at the beginning to a long square wave lead line for the slow bit towards the end.

As before, I got the Midi parts online and processed them in Ableton Live. I combined and reduced them down from the 24 orchestral parts to the 5 here. Fixed up a few dodgy notes. Probably added a few of my own. Then I tempo matched to an orchestral performance of the piece, which is probably the fiddliest and most time consuming bit. There were a few more evenings messing with note lengths and refining the tempos further. So, I’ve been using Korg’s Odyssey plugins up to this point in the process, slouching on the sofa on my laptop, but the next step is to move into my little music room and to practice on the actual ones. Spent a couple more evenings working things out there and then a couple of days trying to film a good run through.

It’s certainly tricky trying to adjust each part as dynamically as I’d like when they’re all coming at me in one big terrifying lump. I’m not mixing or even EQ’ing afterwards so I’m battling to keep a good audible balance between the synths as I go. If I get too involved or too “two-handy” on a synth for too long, I’m neglecting the other four and I’ve missed 5 other things I wanted to do. So I’m relying quite a lot on the Decay slider in the envelope section, as it seems to offer a one-stop dynamic shop that I can adjust on two synths at the same time. I’ve modded all of the Odysseys to have a free-running LFOs also, so I can introduce a slow LFO to the filters to keep them shifting about on their own whilst I adjust something else elsewhere.

I have started re-recording these pieces 'properly', one Odyssey at a time, with view to putting them up somewhere for streaming or perhaps even pressing them onto vinyl. Would sound good on record I reckon. You reckon? And I have a whole shelf full of peculiar synthesizer albums from the 60’s and 70’s that it would be an honour to mingle with.

But hey, thank you so much, everyone who showed up and watched the last video. For all the views and subscriptions and above all, the kind and encouraging comments. That was nuts. I didn’t know you lot were coming! Absoutely amazing and thank you sincerely again.

Oh, to wrap up, here the Odysseys are going balanced out into a Behringer ADA-8200 Interface, which is optically connected into the Adat In of my UAD Apollo. They get their 5 channels of Midi note on, note off information down USB from Ableton Live which is in turn recording the audio coming back. I added some Hall Reverb from Arturia’s LX-24 but nothing has been EQ’d. It’s all how it comes out of the lovely boxes. I did however have a Limiter on the main channel, to put a bit of a lid on some of the more feisty bits.

Toodles!"

Mettalicum - XOR Logic Percussion Synth

video upload by Sid Rockett

"🔊 Exploring the Mettalicum: a new XOR-based percussion synthesizer built for harsh metallic hits, industrial rhythms, and unpredictable noise. Unlike traditional drum machines, the Mettalicum relies on logic gates to generate complex, inharmonic square-wave clusters that cut right through a mix. In this hardware demo, we run through the raw oscillators, tweak the parameters, and patch it into an experimental setup to hear what it can really do.

Ⓜ️ What makes the Mettalicum different?
Traditional subtractive synthesis uses standard waveforms and filters to create drum sounds. The Mettalicum takes a different approach by running multiple square waves through XOR (Exclusive OR) logic chips. When these frequencies interact, they create dense, metallic, and grinding textures perfect for noise music, industrial beats, and lo-fi soundscapes.

🗒️ How does it work?

There are 8 patch points connected to 4 rows (ABCD) and 4 columns (1234) of buttons. Pressing button A1 connects point A to point 1. A2 connects A to 2. B2 connects B to 2 and so on.
It is best used by dedicating rows to outputs and columns to inputs. In this configuration every possible combination of buttons will connect outputs to inputs and cause a change in the behaviour of the synthesizer.

Solton Programmer 24 - Sound exploration and composition of 80' Italo-disco tracks after repair

video upload by Davide Micheli

"In the video, I'm playing the newly repaired electronic instrument.

The Solton Programmer 24 was built by Solton-Ketron Lab around 1985 and it was the first completley and easy programmable music arranger in the history. Due to its structure, for someone is considered the father of Italo-Disco.

This Italian company built at that time this inspiring music electronic machine before any other big company in the word with electronic components available in the market, no dedicated or custom chip as later. In particular, in only 10 minutes I easily composed 3 music tracks in the '80 dance style living the machine inspires me.

The 3 tracks are titled:

1) DRAP; (it could be the base for a rap)
2) Happy track;
3) Past is past;

Hope you enjoy it

Doboz DVNA Synth Custom Patches (No Talking)

video upload by Demover

"Hey everyone!

I thought I'd share some of the patches I created with the DVNA.

I didn't have any specific goal or sound in mind while making them. I just followed my ears and went with whatever felt right.

What do you think about the DVNA? What kind of sounds would you create with it, and how would you use it in your music?

Let me know in the comments! I'm really curious to hear your thoughts!"

Wheel Within the Wheel EP by Michael William Gilbert

A new release via supporting member Michael William Gilbert via Tall Dog Electronics (tindie)

Hello friends,

I am very happy to share this new project with you: an EP of original electronic/electroacoustic fusion music. There are six tracks, including the single "The Prayer Is The Road"(a)/"The Road Is The Prayer"(b). To be clear - prayer in my context is secular: "a practice focusing on gratitude, mindfulness, and reflection to foster positive change, connection, or resilience without appealing to a supernatural being".

"Wheel Within the Wheel", the title track, is influenced by a visit to Tibetan Buddhist monks while they werein the process of creating a sand painting and then destroying it. "Fractal Loup" is about a state of active and curious meditation, a metaphorical wolf mind interpreted with looping. "The Float" is a dream through the worlds of techno and Berlin school. All music recorded & mixed at Alibi’s Little Corner Studio by MWGilbert and mastered by Sean Magee.

Upcoming: thanks to my partners at ElasticStage, "Wheel Within the Wheel" will soon be available as both an LP and a CD! You can check out my previous album "Electronic Music": https://elasticstage.com/mwgilbert

Hope you enjoy "Wheel Within the Wheel". I'm always pleased and grateful to hear what you think, so please let me know!


Thanks for listening!

"Vintage Oberheim FVS-1 (Analog Sweden patchbay mod!!)
Fully functional.

It is a fully functional and—aside from the mod—completely original Oberheim 4-Voice FVS-1.
It was modified by the geniuses at Analog Sweden to be "fully patchable," but the original output board (including the faceplate) is tucked away inside the synth, so it can be restored to its original state if desired!"

BUCHLA 36 (Brutal dark IDM modular synth performance)

video upload by Kevin Rix

"Delve into the dark weirdness of the Buchla 200e. Easily the most interesting instrument I own. It challenges the user to explore new ways to express music and sound. The drums are created by self resonating the 291e triple filter module. Over the summer I explored more complex patching. All the random stereo ripping sounds are from a cross modded 258 classic into the bottom section of the 296 classic. The first batch created a fm like noise when opening the wide knob. Buchla USA recalled the first batch for a cleaner circuit, but I decided to keep it:) I'll be releasing many of these explorations over the next few months.

I'm planning to upload on a regular basis. This world we live in is becoming increasingly more complicated and is about to see a huge shift with the arrival of AI. I want this channel to showcase raw performances and celebrate the human aspect of art and music.

This is an anti-AI channel. Everything is composed and performed by me with no editing. Just raw performances created in the moment. My musical interests take my into strange and unpredictable areas. At the core, I'm a composer of epic cinematic music. Fortunately, it's what I do for work. The music on this channel represents the other curiosities I have with music and sound. AI just spits out sound a likes and has no real soul. I'm not trying to appeal to those who prefer AI playlists. In my opinion, those people are not true fans of music and art. AI isn't affected by culture, community and what's happening in the world, so it can never make a true artistic statement. "

Alesis NanoSynth - Rare Prototype Demo

video upload by John L Rice

"I thought I would document this prototype example of an Alesis NanoSynth I bought on eBay long ago, before I sell it. I didn't take the time to verify if the sounds are all the same as a production model or not, but I suspect there may be some differences? One thing not working as far as I can tell is the built in factory demo that all production versions of Alesis Nano synthesizers have. And yeah, that's not me talking, I wanted to learn how to use the AI text to voice feature in DaVinci Resolve. (sorry not sorry! 😁)

COMPUTALKER SPEECH SYNTHESIZER

You can find a demo of COMPUTALKER in this previous post from back in 2008.

Here are some pics and additional info on the COMPUTALKER via this reddit thread where you'll find a dropbox link to additional docs including some source code. Note the poster on reddit is looking for help on gettig it going. If you can help, reach out there.

This one was spotted and sent in via
M Me who also found some addtional info here.

From the reddit thread:

"The Computalker CT-1 was one of the earliest commercially available speech synthesizers for personal computers. Introduced in late 1976 and shipped beginning in 1977, it was developed by D. Lloyd Rice and Jim Cooper in Santa Monica, California through their company, Computalker Consultants.

Unlike simpler speech devices that played back recorded sounds, the CT-1 was a 9-parameter formant speech synthesizer. A host computer generated control data describing pitch, formant frequencies, fricatives, aspiration, and other speech characteristics, while the CT-1 generated the actual voice waveform in hardware."

"My goal, (which I do think may end up being completely impossible) is to get this up and running and hear it speak. Among the photos, there are some shots of the inside. I understand that this was originally designed for the S-100 bus going as far back as the Altair 8800. Serial number inside and out is 7001 and I can see that a previous owner likely replaced the older capacitors already.

This variant however, In all my searching I cannot seem to find a single reference to anywhere. My best guess with the information I have is that this could be a prototype version that was meant for later computers and perhaps it's missing some type of interface card for maybe an Apple II or TRS-80?

Here is a dropbox link to all of the information I have collected so far. I have found the manual, the software manual (With source code?!) and all sorts of little information. Also there's a lot more photos....

https://www.dropbox.com...

Maybe someone out there has seen this before? I am super excited to keep collecting information on this! Thank you for checking this out!"

Emu SP1200 & SP12 OTBElec SP MIDI Interface w/ Original Box

via this eBay listing

Here's an interesting device from the recent past. According to the listing details below the final batch came out in 2017. It's from OTBElec and this appears to be the first post to feature them on the site. The www.otbelec.com website is no longer live.

This one was spotted and sent in via
M Me. via the listing: "I bought this new & it was part of the final batch made in 2017. I stored it away because my SP12 required servicing & the interface subsequently was never used (or even unwrapped).

This may be the only brand new OTB MIDI in existence.


"The SP MIDI converts non-standard MIDI messages from the SP-1200 to regular MIDI. One such message is note off, which is required to set the length or duration of sequenced notes. The SP MIDI also translates the pitches of bank D to a continuous range of notes to store and sequence external devices. When recording it is necessary to set rec mode.

Internal mode is used to select up to three samples which then have their 16 pitch levels mapped out over the keyboard. Now supporting note off you can play like you would normally expect, where the sample mutes when the key is released. Excellent for looped samples, i.e. bass lines.

External mode is used to sequence other instruments. It uses bank D1-D6 to record notes on one MIDI channel and D7-D8 on another channel. D1-D6 is mapped to a full note range by pad number and pitch, making it possible to play a melody using the pads. Also note off is sent as you hit the pads a second time, unless F1 oneshot is selected. D7-D8 is combined together to give a full range of note numbers and is best used with a keyboard.

Dynamic velocity is maintained, if not Full Level is selected.

The SP MIDI firmware can be updated using a computer with a MIDI interface.

These features also allow pitching and using the loop function on a S950."

Dreadbox Artemis #1 | Winterdagen

video upload by Winterdagen

"I'm a huge fan of Dreadbox synths, and lately I've been lucky enough to get my hands on their newest poly synth Artemis, which just got a really great update. To me, Artemis feels a bit like the best of their Murmux Adept and Typhon combined, but with its own character and unique synthesis possibilities.

For this droney piece, I used lots of the amazing (and newly updated) Sinevibes effects, mainly the super lush reverbs and BBD Playground. Both pretty heavily modulated, which adds to the detuned character of this patch.

Artemis is another incredible synth from Dreadbox and I cant wait to show you more patches and pieces I've been making with it!"
