Progress on the Teensy TDM synth

video upload by Craig Barnes

"Latest update of the Teensy 4.1 based audio library synth. I've ditched the hardware envelopes because they lacked real-time control and only changed on a fresh key press, so now the Electric Druid Envgen8c chips are back in their sockets on envelope duty. I've opted for log envelopes although I think the AS2164 has a lin/log converter, I need to check."

"My 87th original eurorack modular synth DIY projects.
SSI2164 based quad VCO/LFO. Soldering was terribly exhausting.
Self-patching allows you to create complex sounds. It's fun to use with noise machines.

OSCar Repair

"Join me a quest to bring this Oscar synth. Its has mainly cosmetic issues and there are a couple of surprises hidden inside!

Many thanks to

for replacement keys. Well worth a look as they have many obscure parts for many synths.

Music from my forthcoming ATMOS album 'Height Supremacy'. I used this because the main synth line is my OSCar!"

The tuning of SID chips and modern replacements

video upload by MIDI IN

"An interesting question came up this week about the tuning of SIDs. I'll be adding calibration tuning to MIDISID's menu which will solve any issues and also allow tuning to other non-tunable things, but I've spent the day testing the tuning of real SIDs and replacements, and looking at what affects their tuning and documented all of that here."

demo of the b4Modular Series 7 synthesizer part 1 / 2 : the suitcase

video upload by elektronengehirn

"The diy modular synthesizer in a suitcase which Malte Steiner developed between 2024 and 2025. The goal was to build a cheap modular system mainly for live concerts, which is repairable and can go into Checkin Luggage without much worries (something you don't do with Eurorack). So far it is used for several concerts by the projects Elektronengehirn and Notstandskomitee in Berlin and Helsinki, and local Jam sessions here in Aalborg. It is build in a Nanuk 923 case which can remove the lid, the rails are made of wood and wood screws, the front plates are 3D printed.
The system features 2 analog Oscillators / LFOs, one digital oscillator with 6 different modes, an oscillator bank with 6 square waves, triple clock module, 3 slew limiters, a lowpass filter, tone control filter, wave folder, one ring mod / wave folder, 5 VCAs, crossfader, mixer, 2 pressure sensors, a trigger button, unity and gates mixer.
See it in action at this Notstandskomitee concert in Helsinki:"

X1L3 - ARMALYTE - 8580 SID - 3 voice test

video upload by X1L3

"Progress on the SID chip module i've been working on in my spare time.
8580 SID in circuit.

Took a bit of trial and error making the different write routines needed to do the shared register kinds of things with the filter and stuff. But it's moved on from a single voice proof of concept to an almost fully functioning SID module now.

If you were there when the C64 was a thing, you'll know how good this thing is becoming at pretending to be the chip inside the C64 based on this tune that i knocked up quickly for it. It is pretty much doing what a SID can do in a C64. A nostalgic sound. Especially towards the end where the chip chord trills come in.

The test tune shows the different wave forms and how they sound. It confirms that the absolute ton of continuous data coming in isn't a problem. It shows the ultra fast voice multiplexing to do things like the mellow snare sound after the first four bars, and the not so fast switching in tonal variations later on. It also tells me that the click generated by using the sustain register as a voice volume control is a trivial flaw that can't even be heard here.

Tuning is a bit shabby as i don't have a precision Vref on the breaboard. It's close enough slumming it with the running hot 5v regulator for a proof of concept demo though."

BE A BETTER MODULATOR // Understanding Eurorack Modulation with the Thonk TRIPLE MOD

video upload by DivKid

"In this video we’ll break down how common types of modulation for sound synthesis work, how to make the most of them creatively and musically. We’ll do so while demoing the new Triple Mod DIY module from Thonk. Whether it’s creating multi-phonic layered patches needed multiple envelopes, understanding how a Turing Machine works and performing with it, understanding and making Sample & Hold melodic, creating chain reactions with EOC ‘end of cycle’ triggers … there’s lots in this video applicable to LOTS of other modules."

Intellijel Atlantis Modification Guide: How to Give the 'Mod' Slider Finer Controls

video upload by Lido Pigeon

"The Intellijel Atlantis is a truly great synthesizer and one of my all time favourites. However, I've always found it incredibly difficult to dial in a slight vibrato, without using external attenuation. After reaching out to Intellijel, I was guided about how I could possibly go about changing this.

The modification is not a massive one but it does make it much easier to dial in those sounds. It may be possible to get even finer adjustment with a different value resistor (I used a 2k one here) but this one works fine for my needs.

If you're thinking of trying it yourself, it's a fairly easy mod with a very easy soldering job. The only tricky bit was easing off the back panel but as long as you're gentle and take your time it should be fine.

Many thanks to Danjel van Tijn of Intellijel for all his help and assistance with this.
