"The Memorymoog is a classic for its epically fat sound! Though it's not a Plus, we actually prefer non-plus Memorymoogs around here as they are significantly more reliable. This particular unit is in beautiful cosmetic condition as well.

This Memorymoog was previously serviced by Memorymoog specialist Jareth Lackey at Synthpro, and all of the work has been checked by us to make sure it is up to our standards as well. As a finishing touch, we installed our own Memory Liberator upgrade which allows perpetual storage of patch memory without a battery.

This Memorymoog also comes with a Moog 1122 Dual Footswith Pedal, and original owner's manual.

S/N 2268

We believe in transparency when selling “pro serviced” synths so always include documentation of what services every synth we sell has received. Our approach to servicing vintage instruments entails both making sure every synth is working 100% now, and eliminating common failure points to preempt future issues.

This unit received the following services while it was here with us:

Primarily serviced by Jareth Lackey at Synthpro Restorations, we don't have the original invoice but here is what we can tell was done:

Power supply updated
all electrolytic capacitors replaced
Unreliable chips (analog switching ICs, op amps, resistor arrays) replaced
Controls cleaned
Tuning trimmers replaced
Fully tuned and calibrated
Here at Bell Tone:

Memory Liberator F-RAM memory upgrade installed, battery no longer needed and removed!"

08.01.2026 EMU Modular by Exclusively Analogue - Filters


video upload by batchas

00:00 The patch
02:28 Square to Lowpass
05:17 Square to Lowpass: adding resonance
08:08 Sawtooth to Lowpass
09:34 Sawtooth to Lowpass
13:41 Triangle to Lowpass
16:54 Triangle to Lowpass: one octave higher
19:45 Sinewave to Lowpass
22:49 Mixed signal (Square/Saw) with FM to Lowpass
25:54 Mixed signal (Square/Saw) with FM to Lowpass
30:54 Mixed signal (Square/Saw) with FM to Lowpass

Filters in the patch:
1st row: EA2120 Universal Active Filter (original EMU design). I take its low pass output.
2nd row: EA2101 Voltage Controlled Low Pass Filter (redesign)
The EA2101 is a redesign of the original Emu Low Pass Filter using the new SSI2140 IC which is basically an enhanced version of the famous SSM2044 that was designed by Dave Rossum. This is a 4 pole, 24dB, Low Pass Filter with addition of voltage control of the Q (Resonance), which was not on the original Emu LPF."

Kepra - Circuit-Modeled Rhythm (demo)


video upload by Hügelton Instruments

"Kepra is a rhythm instrument developed through detailed analysis of an original Japanese vintage programmable rhythm machine.

Rather than relying on sampled sounds, Kepra recreates each instrument by studying the original analog circuits, measuring waveforms, analyzing spectral content, and reproducing their behavior in software.

Features

• Circuit-inspired drum synthesis
• 12 drum voices
• 16-step sequencer
• NOTE / FLAM / ACC layers
• 8 pattern banks
• Stereo mixer
• Drive and character section
• Internal, host, and external MIDI clock

Available for macOS (AUv2 / VST3) and Windows (VST3).

https://hugelton.itch.io/kepra"


"Hardware Archaeology

Developing Kepra felt less like sampling a drum machine and more like studying an archaeological artifact.

Every instrument was investigated through circuit analysis, waveform measurements, timing analysis, and spectral comparison to better understand how the original hardware produced its sound.

Rather than reproducing recordings, Kepra attempts to reconstruct the behavior behind them.

The Missing Instrument

One voice in Kepra did not exist on the original hardware.

The Shaker was designed as an 'imaginary expansion'—a voice inspired by the architecture and character of the original instrument.

Instead of adding a modern sample-based shaker, it was developed by asking a simple question:

'If the original designers had decided to include a shaker, how might they have built it using the same technology?'

The result is not a historical reproduction, but a speculative reconstruction that aims to remain faithful to the design philosophy of the original machine.

Not an Emulator

Kepra is not intended to be a museum piece.

It is a modern rhythm instrument built from careful hardware analysis, extending the ideas of a classic Japanese drum machine into new creative territory."

7/31/26 (new config) ElectroComp EML 400/401 + CXM 1978 + Alesis MIDIVERB II


video upload by Cfpp0

"This is the new setup of the ElectroComp EML 400/401, with the 400 above the 401. This was actually a test of some stabilizing zip ties. The oscillators are drifting a bit since moving the 400 and I suspect it’s because the cable was switched to the left connector on the 400. Hopefully that’s just some dust. The reverb is from the Alesis MIDIVERB II and the pitchy grainy delay is blended on the CXM 1978."

Hideaway Studio Elfin



Note the above demos and following description are from March 5, 2025. I spotted the Elfin in Hainbach's A Hundred Suns, posted below. There appears to be two synths, an Elfin-08: 8-Voice Functional Prototype Synthesizer, and an Elfin-04 Polysynth.

"Introducing Elfin-04, Hideaway Studio's Compact New 4-Voice Polysynth...

I have been working round the clock for weeks now on my dinky little 8-bit 4-Voice (4 x [2osc+1sub+LFO]) VA Poly Expander with 1960's style transformer-mixed output voicing and finally No's.000 thru 010 are born to the world and receiving very positive feedback from their new owners...... this 4-voice polysynth measuring just 16x12x3cm has full real-time control over her 32 parameters via simple midi ccs and 16 built-in patches.

Hainbach - A Hundred Suns

"A Hundred Suns, the first single from my upcoming album on Seil Records, is out on streaming now. Have a listen a share if you enjoy it: https://distrokid.com/hyperfollow/hai..."

Synth spotting with HAINBACH. I beleive that's an Ensoniq Fizmo paird with the Hideaway Studio Elfin. This appears to be the first post to feature the Elfin.

Synth Vibes (Prophet 10 + Chase Bliss Big Time + CXM1978)


video upload by andman Theory

"Some moody chords played through the incredible Sequential Prophet 10, Chase Bliss Big Time delay pedal, and Chase Bliss CXM 1978 reverb pedal. Filter cutoff is controlled by a pedal along with the delay feedback and send. Enjoy the chill sounds from the Fuzzy Lounge in Seattle.

Recorded direct through a SSL X-Desk, UAD Apollo X16 Gen 2, and Mixpre3."
