Roland TR 606 / TR 608 / TR 808 Mod

This one was spotted and sent in via
M Me.

One was previously listed on Vemia.

"Modified Roland TR-606 / by Filippo Samore / TR-608 > as used by Hainbach on YT [posted here].
The TR-606 in 808 territory and beyond, with tuning, decay and tone mods.

' This Drummachine is on a another level and is a lot of fun (you become very creative) '

' The mod is high-quality and truly enhances the sound engine of the 606
without compromising its handy form factor. It is almost like a TR-808 now,
except maybe a little more interesting, because it is still a charmingly shuffling 606 at its core.'

Examples:
Visit the phunkydesk dot com Domain / > the files after the slash (/) are as follows:
608_BD.wav, Loop1.wav, Loop2.wav
(there is no distortion/overdrive or clipping converters!)

The main modification in this revisited classic is the complete redesign of the kick drum circuit
with a lot of borrowed technology from the 808!

+ Kick: Tune, env Control, tone and decay.
You can also send the kick through the second output separately!
+ The Kick can also have "almost infinite" decay

+ Snare: same borrowed technology from the 808 but with an improved decay length.
It gives access to tune, snappy and decay.

+ L.H Toms: Tune independent from each other and cuts out the annoying noise present in their circuit.

+ Hi-Hats: Tune and decay, separate for both open and closed hats

++ Original Roland TR 606 carrying case
++ Device is serviced (while Mod)

++ Device checked in endurance test
(Batteries or the 9V TR-606 power supply)"

Audio Computer Interview London Synth and Pedal Expo 2026

video upload by Take the Fear out the Gear

"Hi everybody this time we bring you the Audio.Computer Interview at the London Synth and Pedal Expo 2026 talking about the beat friend drum machine

Beat Friend is the first offering from audio.computer, a UK-based duo making ‘benevolent, semi-autonomous music machines’. Beat Friend is an analogue drum machine, using circuits based on the ‘twin-t’s from the legendary Roland CR-78. Each drum has a slider that changes the drum’s complexity within one of the 30+ preset patterns, which already allows hundreds of variations on any given beat.

But wait! There’s more! Turning the Enthusiasm knob allows Beat Friend to add or subtract notes from the pattern as it sees fit, either keeping the pulse of the pattern or going completely off piste. It's like having an enthusiastic robot Labrador playing a 70's electronic drum kit just for you.
All the sounds are routed through a Triforce of digital and analogue effects, which...well, you just have to turn knobs to find out what they do. If you’ve ever wanted to base a track on a 7/8 samba through a bit-and sample crusher, then this is the unit for you.
And, sure, if you’re a control freak who absolutely must design every bar, you can control the drums individually via MIDI. It even includes a letterpress-printed manual, numbered to match your unit.
Beat Friend plays in glorious mono and is powered by a universal 12V power supply (included in the box)."

"No external effects used. The tapped delay comes from the 'Espace Temps' module (top of the matrix).
The output of Sequence (1027) A is going into the quantizer (top of the matrix). The quantizer switches between 3 different scales via CV coming from the Mix Sequencer (1050)."

Plinky's Arp Sequencer Explained

video upload by Nathan Plante Synths

"In this video I go through all of the arp related parameters on Plinky and also show you three different patching ideas for arps. The arp system isn't nearly as deep as some of the other major systems on Plinky, but there is still a lot of creative potential to be unlocked here. This is the last major system on Plinky that I haven't yet covered, so it's high time that this video got made. Thanks to all the viewers who requested this in the recent poll!

Fieldtone Weaver
Gene Synths GX

What a great combo for instant glitch and lofi melancholy.

Some slight reverb and delay added in the mixer but otherwise clean.

The Weaver is so intuitive and you can instantly get it to play nicely with your gear. Here I sampled the short notes off the GX at the start then just played over the Weaver doing its thing. Sampling the notes you’re going to play means that whatever gets thrown out by the random algorithms will be in tune. That’s why I was able to just twist the knob and go with whatever it gave me.

Great way to spend a Sunday recovering from jet lag 😀"

Deep Textures | DecadeBridge Sn Standalone Drone Performance

video upload by Andre Bregegere

"In this session, I dive into the DecadeBridge Sn, using it as a purely standalone sound source for an improvised drone performance.

The goal of this exploration was to push beyond simple sustain and find the hidden textures, grit, and evolving timbres tucked inside this compact synth. By moving through various frequency ranges and modulation points, the Sn reveals a surprising amount of movement and harmonic complexity. Expect a journey through heavy low-end oscillations, shimmering high-frequency artifacts, and raw, unpolished sonic landscapes.

Recorded live, lightly mixed and mastered in Pro Tools."
