Pics of the inside below.

"From my testing I gathered the following: the two pole switch turns the filter control on (down position) or off (up position). When the filter control is on, the pedal acts like intensity or swell, and the speed is controlled by the knob. When the pole switch is off, the signal passes through with the option to either bypass for a clean signal or act as a swell pedal depending on whether the pushbutton switch is pressed (located at maximum pedal depression). This is the limit of what I could test. Please keep in mind, the pedal is sold as is.

SN 0073

I have installed two new 9V batteries, which have only been used for testing the pedal during the demo video filmed on 12/07/25. The unit has remained off since testing."

LinnStrument 200 Bumpy Surface

video upload by Sound Workshop

"our Bumpy #LinnStrument Surface makes it easier to play by feel instead of by sight. We’ve shipped over 150 surfaces for LinnStrument 128, and preorders are now open for LinnStrumenf 200. Shipping in Feb 2026. Order before Dec 8 for a 15% discount.

Http://www.soundwork.shop/linnstrument"

"One BLACK aftermarket silicone surface for LinnStrument 128. LinnStrument not included.

This surface makes it easier to play LinnStrument by feel instead of by sight. Each row is shaped like a long speedbump, which has three benefits:

Guides fingers to stay on target during long pitch slides

Provides confident tactile feedback when shifting a finger up/down between rows or hitting a double stop

Allows more intentional Y expression by feeling for the front, back, or crest of the bump

The grooves are centered over the top of the notes, instead of on the boundaries. The way the finger can feel when it's on target.

The root note bumps or dots have been removed to make alternate tunings easier.


This surface is great for playing LinnStrument with eyes closed or playing with two hands.

International Customers: prices listed do not include import taxes or fees. Please note that you may need to pay an additional custom when importing.

Black Surface Back Side Cosmetic Issue (Oct 22, 2025): the remaining 8 black surfaces have unintended paint application on the back side.

Prismatci Spray II

video upload by Arman Bohn

"My devices can be purchased here:
https://distropolisgoods.com/

Prismatic Spray II should be out in a few days!

Let's take a look at some more of the new features in the Prismatic Spray II.

I have the new web serial visualization feature running on a Mac this time. I did a screen recording and comped it into this video to demonstrate the possibilities of web serial display & visualizations.

I start by showing how the DETUNE knob works and can create a "chorus" type effect between the two bytebeat engines.

I move on to the SLOW DOWN knob and show how you can slow the bytebeats down and even freeze time - allowing for wavetable-ish type control over the sound. (You can also accomplish this by creating very small loops with the looping feature).

MIDI PITCH BEND is shown with the help the Phantasmal Force micro MIDI controller.

GLIDE allows for some portamento action between notes.

The analog FILTER runs in stereo and is also MIDI controllable.

I finish up with an explanation of the PITCH SCALING feature, which can stretch bytebeat playback determined by a user-specified root note.

Whew!"

Similis - self sequenced

video upload by DecadeBridge

"Similis is a lo-fi synth that has several different patches. Here it is set to run a random sequence over a major or minor scale. This preset can be switched between 1 or 2 oscillators, each playing a random note independent of each other.

Pot A/CV in A sets the root note.
Pot B/CV in B sets the range of notes of the chosen scale.
Pot C/CV in C sets the rate of the sequencer (controlled using an envelope generator in this example)
Switch A sets the waveform (Sine, Saw or Square)
Switch B has 3 different settings (Stop the sequencer playback on its current note, run the sequencer, run the sequencer and add an additional synth voice.)
Switch C sets the scale."

Similis - Detune

video upload by DecadeBridge

"Similis is a lo-fi/chiptune style synth consisting of several different presets.
This Similis patch stacks 3 oscillators and detunes them against each other.

Pot A/CV in A controls the root note.

Pot B/CV in B controls the detune of the other 2 oscillators.
Pot C/CV in C controls the level of the 2 additional oscillators.
The root note pitch is being controlled by a random scale from Pam's Pro Workout.
Here an envelope generator is controlling the level of the detuned oscillators through CV in C.
Switches A B and C change each oscillators waveform (sine, saw, square)"

Similis - Chords

video upload by DecadeBridge

"Similis is a lofi synthesiser that has 6 different presets.

This is an example of the 'chord' preset.
The first control sets the root note of the chord. The second selects 1 of the 10 chords available (5 major variations and 5 minor). The third control sets the volume of the notes that make up the chord except the root. Each of these controls has a CV input.
Here the root note is controlled by the keystep pitch. The VCA is being gated by the keysteps gate out. The volume of the chord notes are controlled using the mod wheel."

https://decadebridge.etsy.com/



"Similis is a lofi chip tune synthesiser that uses basic waveforms to generate it's sound.

Features:-
6 different settings (TYPE) from stacked oscillators to chords to self sequencing.
The setting selection can also be stepped using a trigger/gate signal for some odd patch skipping.

Each control can also has a CV input for connecting external gear.

Settings 1-3 deal with stacked oscillators.
3 oscillators with independent pitch. Sine, Saw and Triangle waves.
3 stacked oscillators. The first sets the root note and the other two are detuned plus and minus from the root.
The two detuned oscillators can be faded in.
Chords. The first oscillator sets the root note. The second control sets the chord (5 major chord variations and 5 minor) The amount of voices in the chord can be altered using switch C. The chord notes can be faded in to give a swell effect.
Settings 4-6. Simple sequencing.
The last three patches are random sequencers. The first is free running. Select between, chromatic, major and minor scales. The range and rate of the sequence can be altered and a second oscillator can also be brought into the sound.
The last two patches substitute the rate control as a mix for other voices. A short trigger signal is needed to tell Similis to choose a new random note/s within it’s selected scale.

The output is run through a 3 position passive LPF which turns into a Low pass gate when the VCA switch is down and a CV signal is connected to the VCA input."

MDScaler Machinedrum Tonal Quantizer for Monome Norns #elektron #machinedrum #monome

video upload by HANJŌ

"Check out MDScaler — a Monome Norns script I developed to bring tonal pitch control and creative randomness to the Elektron Machinedrum (or any CC-controllable synth).

With MDScaler, you can:
Quantize any incoming CC to a musical scale of your choice
Randomize notes within the active scale for generative ideas
Map to Machinedrum’s pitch parameter (using Tonal mode in X firmware)
Use parameter-lock compatible CC control so each step can evolve melodically
Switch encoder modes: channel select, CC number, note stepping, octave cycling
In this demo video, I walk through the interface, show it in action on a pattern, and explore how randomness + scale constraints can yield interesting melodic/rhythmic results.

Controls (via Norns / MDScaler):
Element Function
E1 Change Scale Mode
E2 Adjust Root Note (C, C#, D, etc.)
E3 Toggle between Channel / CC / Note modes
K2 Send a Random Note from current scale
K3 Mode Select (toggling E3 behavior)
K3 + K2 Cycle Octave
Pitch mapping / defaults:
By default, MDScaler maps to Machinedrum tracks via CCs using a consistent offset pattern across groups of 4 tracks (16, 40, 72, 96) per channel. You can reassign or explore as desired.

Press release follows:

Ocean Swift Launches “Sample Tester” - A Free, Instant Tool for Sonic Curation and Auditioning

Ocean Swift announces the release of Sample Tester, a compact, zero-friction instrument designed for rapid auditioning, tuning checks, and curation of oscillator-style samples. Sample Tester is available now as a free Kontakt Player-compatible tool, empowering producers, sound designers, and sample library creators to streamline their workflow.

A Tool That Speeds Up the Process

With Sample Tester, users can drag and drop a sample file and immediately hear it played polyphonically, allowing quick assessment of tuning, harmonic behavior, and musical context. The instrument:

Automatically detects or permits manual setting of the root note
Displays MIR-derived metrics such as pitch, peak, RMS, and loudness at a glance
Offers an engine toggle to compare Direct-From-Disk streaming versus Time Machine Pro sample stretching
Provides one-click amplitude envelope shapes (Perc, Bell, Piano, Lead, Pad)
Supports NKS / NKS2 mappings, compatible with hardware control surfaces
Works fully in the free Kontakt Player—no full Kontakt license required
In modern production environments, sound designers and producers often sift through large volumes of raw samples. Determining which ones will behave musically, tune correctly, or integrate well into a kit or melodic instrument can be time-consuming. Sample Tester accelerates that decision-making:

Instant feedback: No waiting for heavy DAW setup
Precise metrics: MIR data gives insight beyond the ear alone
Real-time auditioning: Hear the sample in chords or context, not just as a solo note
Flexible workflow: Works for tonal, looped, oscillator-style materials
These features combine to let creators “decide faster, tune with confidence, and build better libraries.”

Ocean Swift positions Sample Tester as a perfect companion to its Spectral Oscillators Toolkits, but the tool is equally useful for any user working with tonal or looped sample material.

Exquis - Ableton Live integration (feat Primo Taut)

video upload by Intuitive Instruments

Press release follows:

Intuitive Instruments improves Exquis MPE controller with firmware 2.2.0 update alongside Ableton Live, Bitwig Studio, and Cockos Reaper workflow-merging scripts

SAINT-CYPRIEN, FRANCE: Intuitive Instruments is proud to announce improvements to the award-winning Exquis MPE (MIDI Polyphonic Expression) controller with major updates coming courtesy of introducing firmware 2.2.0 alongside software scripts to merge its workflow with Ableton Live, Bitwig Studio, and Cockos Reaper DAWs (Digital Audio Workstations) — wholeheartedly representing several simultaneous steps towards the inspirational solutions for music lovers creator’s goal of ultimately making music-making seamless by turning the flagship instrument itself into the ultimate lightweight and compact creative hub — as of September 8…

Exquis enables seamless and natural interaction with all DAW software, MIDI synthesizers, and modular systems by becoming a direct extension of its user’s creativity as an expressive and intuitive MPE controller comprising a hexagonal matrix of 61 backlit soft silicon keys arranged as consecutive notes (semitones) horizontally and harmonious notes (thirds) vertically — from the lowest at the bottom to the highest at the top — that provide independent gestural control over four different dimensions: velocity (strike force), horizontal tilt (X axis — pitch bend), vertical tilt (Y axis — CC#74), and pressure (Z axis — channel pressure or polyphonic aftertouch). Alongside a namesake companion app — itself optionally offering an experience akin to traditional composition software — available on macOS and Windows with support for VST, VST3, and AUv3 audio plug-in formats, Intuitive Instruments’ flagship instrument is intended to provide musicians of all levels with a fun and intuitive way of creating melodies and progressions, fully exploiting sonic potential in the process of doing so — whether working with third-party software over the USB (Type-C) connection, third-party software or hardware synthesizers through the MIDI IN and OUT (minijack) connections, and modular synthesizers via CV (control voltage) with dedicated 0-5V (minijack) connections for GATE (V-Trigger), PITCH (V/Oct), and MOD (pressure or velocity). These top out a lightweight (600g) and compact — 36 mm (H) x 146 mm (W) x 317 mm (D) — desktop design that also incorporates four rotary/push encoders and a six-zone capacitive touch slider, plus a series of selection, undo/redo, and action buttons, providing precise and intuitive control collectively over any user’s sound while enhancing interaction with the app.

Meet You At The Top

video upload by davidryle

"A two part piece. Both are pitch voltage quantization controlled from the ACL Sinfonion. I switch presets through the first part from preset 1 - 4 and in the second half I leave it on preset 5.

The Sinfonion chord section is sending pitch quantization to the Doepfer A-111-4 quad VCO and A-105-4 quad SSI filter. The mixer is the Corsynth T-Mixer. The Empress reverb in Ambient Swell green mode is used.

The opening voice is Channel 2 of the Sinfonion and is sent to the Dotcom Q206 with the Dove D502 in BP mode P1, then an SSL Serge Resonant EQ and finally the Strymon Blue Sky.

A counter voice is the Channel 3 quantizer to a pair of Synthetic Sound Labs TZ-VC Oscillators to the Oakley VC-SVF in BP mode. The audio is routed through a Moon 517S high pass filter to roll of the lower mid tones. I used an instance of Relab Development's LX480 classic Lexicon reverb. This same voice is used for the main melodic part in the second section.

The Channel 1 of the Sinfonion is to the bass voice which is the Dotcom Q169 Oscillator++ and Grove Audio G294A ladder filter.

The Sinfonion arpeggiator part is to the STG oscillator duet and the Dove D501 2069 filter. The signal is sent through the Modcan 73B dual delay. In the first section this voice is solo, but in the second section I added in a duplicated run of the MosLab 901/904A through a different envelope which is timed a bit more sparse and sent through the second section of the 73B delay.

Most of my time was spent mixing levels and changing the timing of the SSL Hagiwo Geo-Gruvn euclidean sequencer. The clock timing was controlled by row 3 of the Moon 563 trigger seq. I used two different memory presets on the Geo-Gruvn for each section. These timings were used for the gate controls to the SSL Octal VCA, CV-8 Breakout and AD/AR Expander. The eight channel vca handled four of the voices. Very cool array of modules.

I also sent and effort to control the timing of the STG Voltage Mini Store's timing with row 2 of the 563. The right VMS is used for the Root control to the Sinfonion. The faster moving left VMS is to the arpeggiator of the Sinfonion.

The Sinfonion is using various cv's from the Q960 step sequencers to affect the chord spread and note selections. Also an LFO is used to affect the pre-transpose of the chord section.

A convoluted patch using the Lower West Side Studios CGS88 triple switch, the Dove D900 sequencer and three voltage sources to send control voltage to the transpose on the Sinfonion. I used the Moon 564 trigger stage 1 to turn this on and off by hand when needed.

The final clangorous opening and ending patch voice was the Mutable Instruments Rings through the Behringer Bode Frequency Shifter clone and the Encore Frequency Shifter, and on through the Tip Top Z-DSP signal processor running Halls of Valhalla reverb (Niflheim preset). It was also the midway noise rush background sound where the sections changed. These were added later in Cubase and triggered by hand.

The sections were performed at once live to Cubase and video edited in Final Cut Pro."

EXPLORING THE ELGAM CAROUSEL

video upload by Vintage Audio Institute Italia

"The mythical Elgam Carousel from 1976 - is it a toy or a songwriting tool?
It's at least safe to say it's an analog drum machine and arpeggiator, with 3 chord sounds and a bass line generator that swings real good - here recorded completely dry without effects.

The Groove box that sparked todays hype of the genre - a stunningly well-designed piece of gear with a great analog vibe that stays relevant. Originally, this was the Crazy Hands section from the Elgam Broadway organ.

The Carousel is comprised of 4 sections :
1. Drum Machine
2. Bass Section - generating a choice of two bass-lines
3. Chord section - three sounds (Harpsichord, Honki tonk and Piano)
4. Arpeggio section - one sound with adjustable decay and 2 stackable harmonies.

The melodic sections change depending on the rhythm engaged and follow the tonality of the keyboard. Sonically the sounds gel really nicely, this machine is the sum of all its parts, the rhythms and bass lines are well-programmed, the bass has great lines and the arpeggiator adds that magic.
The drum section offers 15 fixed rhythms of great analog drum sounds. No individual drum sound mute options, but hey - at least you can add maracas.

You have the option to select the tonality with one finger for simple root chords and selecting minor, 7th or diminished with the foot pedal. Or you can choose to operate it in manual mode and potentially play more complicated chords.

In manual mode the bass and arpeggiator only makes sense of chords of three notes while the chord section reads all the notes at the same time. On the back we usually have a single audio output and a pedal switch connector for stop/start and minor and 7th but this one had some other mods added that were disconnected.

This unit was just serviced and will go up for sale next week so holler if you're interested - it's in good condition"
