Juno 106 chorus board rack conversion

video upload by Harry Axten

"Something I built for myself earlier this year after scoring the chorus board from a scrapped Juno 106 on eBay. Housed it in a 1U rack box with a power supply and controls for the chorus mode and high-pass filter. Works exactly as it does in the synth with 1 mono in and 2 stereo outs. Demonstrated with a Prophet 5 Rev 3.3."

T-16 Semi-Modular Analog Synthesizer (based on ARP 2600) - DEMO 004

video upload by Nitecaller.

"Felt like creating something that was different to the last few drone-y videos and ended up with this! The range of this instrument is incredible.

Audio signal chain: T-16, Focusrite 18i20, Ableton Live, Valhalla Supermassive, Shadow Hills Mastering Compressor VST.

[The T-16 is a custom semi-modular synth largely based on the analog circuits of the original ARP 2600 and ARP Odyssey, with additional modifications and modules.]

Casio SK100 1986 8-Bit Sampler + Patch Bay & Pitch Mod

Note: Auction links are affiliate links for which the site may be compensated.
video upload by Canned Sound

via this Reverb listing

"Rare 1986 Casio SK-100 8-bit sampling keyboard custom modified with a 25 point modulation patch bay and pitch control section mounted on a metallic graphite externally attached console with a unique solid aluminium 1970s Hitachi 'wedge' knob. This is a weird, unpredictable, lo-fi and chaotic sampling instrument with a warm gritty sound which will inspire any alternative electronic musician and sound designer.

When the patch matrix is in use an array of warped effects, drones and loops can be generated; applying multiple connections produces an increasingly complex range of cyclic, pitch dropped, fractured, tonal, bit crushed, flanged, distorted, aliasing digital noise and bizarre sequences which affect any sound you record using the sampling feature. The pitch mod takes the sound up in pitch and down to crushing aliasing lows, also affecting the SK 100's pre-set sounds. Five stackable patch cables included.

Specs:
-25 point ROM modulation patch bay
-Pitch control function
-5 different dynamic envelopes can be applied to your samples (a long and short sample can be recorded and stored).
-Loop and reverse effects.
-The samples can be featured in the tempo adjustable onboard rhythm sequences.
-12 preset sounds
-12 preset rhythms
-Chord memory
-7 keyboard-based drum sounds"

Inside Tom Oberheim’s Garage Workshop

video upload by Anthony Marinelli Music

See the full interview here, and the SEM Story here.

"Step inside the legendary garage workshop of Tom Oberheim—the birthplace of some of the most iconic sounds in music history. In this rare behind-the-scenes tour, Tom shares his latest creation: a custom-built computer he’s designing entirely from scratch—just because he loves the way it sounds.

Along the way, Tom opens up his treasure chest of innovations, showing us priceless prototypes from his storied career, including the original Maestro Phase Shifter prototype and circuit boards that paved the way for his groundbreaking synthesizers.

I’m joined by Rob Rosen (Rosen Sound) and Marcus Ryle (Alesis, Line 6) as we hear directly from Tom himself, walking through this sacred space filled with history, innovation, and pure sonic imagination.
👉 Don’t miss this intimate glimpse into the genius of a true pioneer."

Kosmische Ambient on the Manual Override

video upload by Biopower Audio

"The Biopower HI Five Eurorack modular synthesizer CV controller interface, paired with the remote Manual Override faderbank, allows you fine-detail expressive control over ambient patches.

This patch blends a drone from @befacosynth Noise Plethora with a fast arpeggio on Mutable Instruments' Rings. Fader Channel A modulates the drone pitch, B modulates a clock divider on the arpeggio, C and E modulate timbral parameters on rings, and D triggers a step in a sequence for the bass note of the quantized arpeggio.
