A Nice Song for Summer
video upload by Hologram Electronics
"What can you create with just a monophonic synth, a guitar, and some Hologram effects pedals?
This track is an exploration of that question — a study in restraint, sound design, and the textures that emerge when you limit your tools and lean into the process. The core instruments here are the Moog Messenger, an electric guitar, and carefully chosen chains of effects.
Every element in this track — aside from the recorded acoustic drums in the first half of the medley — passed through Chroma Console, shaping and coloring the sound along the way, from subtle crunch and stereo widening to melting delays and cavernous reverb."

Prisma July 2025 Update
video upload by Rob Papen
"Prisma 1.0.8 update that loads RAW-2, SynFeX, and WirePluck.
New presets:
Bank 01 Super Pads 01 (11 new presets)
Bank 02 Motion Picture 01 ( 5 new presets)
Bank 04 Dance Arp 01 (7 new presets)
Bank 08 Classic Stacks 01 (8 new presets)
Bank 10 RAW-2 Edgy 01 (10 new presets)
To select the new presets, go to the 'bank manager' and the 'preset' tab, and then select 'order by date', which makes the newest presets appear on top of the list in the bank manager.
Please note that if you update your Prisma, the stand-alone version requires you to reselect your audio card and MIDI keyboard.
The stand-alone version is on the Mac inside the applications\Rob Papen\ folder, and on PC, it installs a desktop quicklink."
UDO RBN-1 Ribbon Controller — Part 2
video upload by UDO Audio
"Following the getting started video for the RBN-1, here's some more top tips on how to get the most out of your RBN-1, courtousy of Hazel Mills.
It's worth mentioning that all of these features are possible on the Super Gemini, which has our ribbon built into the chassis."

"Oscillator 2 frequency modulating oscillators 1 & 3.
No external effect added. Direct outputs to stereo track. The delay comes from the tap delay module added in the matrix (top right)."

IG00151 VCA Clone for YAMAHA CS Synthesizers (CS5,CS15,CS30,CS50,CS60,CS80)
Note: links to listings are affiliate links for which the site may be compensated.
You can find them on Reverb and Ebay.
"The clone is fully drop-in replaceable and is able to coexist with the original vintage chips in the same synthesizer. It can function as VCA and current source for envelope controller on M-cards, or control voltages for TRG boards (and on any other board that uses that chip). It has the same control voltage cutoff point and similar non-linear control curve as the original, so all the control sliders work the same."
Additional details follow:
"The iG00151AP is a replicant of the rare IG00151 Voltage Controlled Amplifier (VCA) chip, which was used by Yamaha in their CS-series analog synthesizers and organs from the 1970s and 80s. The iG00151AP was carefully engineered from the original chip, retaining all of its characteristics and properties, including the peculiar non-linear control curve and cutoff, input and output impedances, and identical power consumption at the same gain setting. This makes the iG00151AP the only "clone" available today that is fully drop-in replaceable and is able to coexist with the original vintage chips in the same synthesizer. While the originals are getting more expensive and harder to find, the availability of the iG00151AP ensures that the CS-series analog synthesizers remain serviceable. One CS-80 synthesizer contains 210 of these chips!
INSTALLATION
To install the iG00151AP, ensure that the marked PIN 1 location on the part matches PIN 1 location on the circuit board. With the pins pointing down, PIN 1 on the original chip is on the left when facing the part number, while the iG00151AP has PIN 1 on the left when facing the component side (not the part number). Carefully orient the part properly and solder it to the circuit board. Clip excess leads as necessary.
WARNING: As with the original chip, a reverse installation will damage the part when power is applied!
CALIBRATION
After installing the part, allow the instrument to warm up and stabilize for at least 30 minutes, then recalibrate the circuit following the procedures of the original manufacturer. Similar to the original chip, the gain may vary from unit to unit. Proper calibration will ensure that the new part performs the same as the original.
As with the original chip, the iG00151AP may have a similar input offset that varies from unit to unit. This manifests itself as a control voltage (CV) feedthrough to the output. Depending on the application, it may be necessary to trim the offset, but this is usually provided in the vintage circuit, if required. No additional offset trim circuitry is necessary if it is installed in the original circuit.
The iG00151AP is compatible with Yamaha CS-80, CS-70m, CS-60, CS-50, CS-40m, CS-30, CS-20m, CS-15D, CS-15, CS-10, CS-5, and other synthesizers and organs that use the IG00151 VCA chip."

Demo with the Sonicware Texture Lab & other modules.
"Radiant Firmware 2.0 is out now!
Introducing the new Triad: three fresh effects to spice up your soundscape:
• Holy Reverb – a lush, shimmering reverb enhanced with tremolo
• Dust Delay – a saturated, crossfading delay featuring authentic tape noise
• Modal Resonator – a membrane-inspired modal resonator
We’ve also refined gain staging and squashed several bugs from the previous version.
