"Dave Smith Instruments Mono Evolver in fantastic condition. This has the upgraded PE or Potentiometer Edition boards, but the original endless encoder boards are included if you wanted to revert it!

This is an amazing and very unique sounding synth which I love, but have to let go. It has never been gigged and has only had light use in a non-smoking home studio.

There are no scratches on the wood end-cheeks or the front panel or keys, there is a small mark on the rear visible in the photos. It is generally in very good condition, near mint.

It comes with the power cable and plug adapters for different regions. It will be packaged extremely carefully, so it arrives safely, with insurance."

Oberheim Xpander XP-1 6-voice Analog Synthesizer SN Y61801 w/ Original Manual

Note: links to listings are affiliate links for which the site may be compensated.


via this eBay listing

"Experience one of the most legendary analog synthesizers ever made — the Oberheim Xpander XP-1. Built in Los Angeles, California, this 1980s powerhouse defined modular-style flexibility in a desktop form. With six independent voices, twelve VCOs, and one of the deepest modulation matrices of its era, the Xpander remains a timeless studio centerpiece for collectors, sound designers, and film composers.

• Tested & fully functional — all six voices respond properly.

• Cosmetic wear includes two surface scratches on the top panel (see photos).

• Metal hard case included — foam interior has deteriorated due to age but still protects the unit securely.

• Clean, smoke-free environment.

• Overall: Very good vintage condition, with expected signs of use for a classic Oberheim."

Pamela's PRO Workout - 1x PPQN


video upload by ALM TV

"Clocking Pamela’s PRO Workout at x1 PPQN with an ASQ-1 sequence to create a completely random Castle setting each time a note is triggered. 🪄✨ . 🔵 The ASQ-1 is started, sequencing a dual oscillator Akemie’s Castle melody. Pam’s PPQN is set to x1, with all outputs set to produce x1 random waves. The gate out of the ASQ-1’s sequence is duplicated to the Clock input of Pam. At each note in the sequence, Pam’s 8 random signals are advanced due to the x1 PPQN setting. The outputs are patched to modulate most of the Castle’s parameters, resulting in a totally random sound for each note in the sequence. 🏯"

E FUN!WLK FILTERBANK // CLEAN vs. DISTORSION // TORSO S-4 // EMPRESS Zoia // No Talking


video upload by LESINDES

"The WLK FILTERBANK is used on SPEECH, a NARRATION LOOP explaining the WLK and the SND filterbanks in ENGLISH and GERMAN. Extreme use of the frequency bands and also the distosion/saturation settings demonstrate the ability of the units und explore its/their boundaries.
SND FB-14 speech demo will be uploaded soon.

HAVE FUN!

The humming noise in the background is a crane that has been working for hours on the street to repair a water pipe of a neighboring building. I tried to remove it but I wasn’t entirely successful. To cut a long story short: Since the units dramatically compress the signal they push it but they are not generating it!"

First experiment with the Korg Phase8


video upload by Richard Devine

"For this experiment I have a few MIDI scripts running from Logic Audio's MIDI scriptor plugin to create these complex almost Autechre like MIDI rhythms to all of the tines, while I have various objects, metal, magnets, metal rods, tin foil, springs, coils, and some extra Solenoid triggers to help create some interesting interactions and new sounds with the Phase 8"

Ambient Electronica with Game Boy Advance and OP-1 field | Praise 2026-02-21 by atnr


video upload by atnr

"Ambient electronica featuring gentle synth tones, electric piano, and Game Boy sounds.

Created with Game Boy Advance, ‪@teenageengineering‬ OP-1 field, ‪@YamahaSynthsOfficial‬ CS01, and norns shield.

On the Game Boy Advance, sequences are programmed using Stepper. The sound runs through monotron DELAY, where delay is applied and the filter is manipulated in real time.

On the OP-1 field, a 32 bar synth harmony loop is played and processed through ‪@ChaseBlissAudio‬ GENERATION LOSS MKII and LOST+FOUND.

On the CS-01, I use a slow attack patch with the waveform set to PWM, performing while adjusting PWM speed and modulation.

On the norns shield, electric piano phrases are recorded into graintopia, processed granularly, and played back.

All devices share the same tempo, but no sync cables are used."
