'An Unearthly Choir' on an AJH SYNTH #eurorack Modular Synth System
video upload by AJH Synth Official
"A 3-part/3-voice use of human voice & choir-like sounds performed on a AJH SYNTH RadioPhonic Eurorack modular system. No samples were used, this is purely analogue oscillators, filters, modulation, and a wave form animator one one of the voices.
Whilst the RadioPhonic system was used here, it is of course modular, so these modules can be acquired individually or as part of smaller systems, meaning each part could be achieved using the same modules in your own custom system.
Key MiniMod modules used:
Vintage Transistor Core VCO
Wave Swam
Fixed Filter Bank 914
Transistor Ladder Filter
Sonic XV Diode Ladder Filter

"Certain voices of the Prophet-5 five-voice polyphony begin to distort unnaturally. The chords are broken down, yet maintain an unstable equilibrium that still retains musical meaning. What becomes clear here is that this glitch is not just noise, but a structure that complements what the Prophet-5 itself could not say.
The sequence is interrupted, and the notes are missing. But these imperfections resonate as fragments of future possibilities. The noise is not a 'foreign object,' but resonates with analog harmonics, bringing to light the contours of broken memories.
The way the glitch noise gradually swallows the sound, with a faint trail of reverberation, is more like a memory sinking to the bottom of deep water than the end of music. The pads lose resolution, the arpeggios freeze at the end of the loop, and all that remains in the end is the faint reverberation of analog noise.
Glitch is not destruction, but a new language that allows the Prophet-5 to continue speaking beyond the break of time.
In this work, 'not sounding right' is not a failure, but another form of musical perfection. 'MemoryScan' is one of the few works in which the memory of the Prophet-5 and the poetics of noise are in perfect harmony."
Minimal House w/ KORG MS-20 Prophet-10, CP-88 | Subversion 2025-05-25 by atnr
video upload by atnr
"A piece created with the KORG @KORG_INC MS-20, @SequentialLLC Prophet-10, and YAMAHA CP-88—minimal house where an even kick and evolving bass line support electric-piano and synth layers.
MS-20: The bass line is driven via MIDI sequencing, while I manually tweak the filter and pitch-bend.
CP-88: Plays a Wurlitzer electric-piano patch; delay is added in the intro and outro.
Prophet-10: Provides the synth lead."
Mors aliquid novi | A Prophet VS and acoustic 12-string guitar ambient improvisation soundscape
video upload by MIDERA
"Earlier this month I managed to replace the bone saddle in my 12 string guitar. I guess years of messing with the saddle (as well as expansion contraction in the basement gloom) caused it to deteriorate to a point where the strings wouldn't touch it and it sounded horrible. I've had this guitar since 2001, so somewhere around 14 years. It's felt nice to bring it back to that feeling of new, even though it was never well cared for. I just love the feel and sound of it. These videos where I even mention a guitar usually do distinctly awful. I guess the idea of mixing guitar with synths just rubs people the wrong way. But I liked it.

Waldorf Pulse & Pulse 2 - Don Solaris Soundset
video upload by Don Solaris
"Available at: https://www.donsolaris.com/?page_id=3633
Why DCOs? Unlike traditional VCOs (voltage-controlled oscillators), DCOs maintain consistent pitch and phase – which may sound like a subtle difference, but in practice, it’s key to achieving harder, tighter, and more aggressive bass. DCO-based synths like the Pulse don’t drift or smear. They hit with precision, punch, and presence, which is especially crucial when you want bass that stays locked in with your drums and doesn’t fall apart under compression or saturation."

"Dave Smith Instruments Poly Evolver Keyboard in excellent condition. Encoder version with updated boards.
Main Board: 2.2 Voice board: 2.2 DSP Board: 3.5
I'm the second owner, and both studios were non-smoking. No gigging with this one.
This is a special synth from a very special manufacturer. Dave Smith, from designing the famous Prophet 5 to his defining the MIDI spec, really dedicated himself to producing unique and capable instruments and technologies. This Poly Evolver is one of those. Full Specs below but the fact that this is a hybrid synth, combining analog and digital synthesis, with incredible modulation and built-in sequences, show the mind of genius Dave Smith.
Also the purple heart wood is an beautiful accent for this particular synth."
