"So I don't know much about this thing. I haven't even tried to power it up. Would probably be fun in noise sets or for learning electronics.

I have no reason to think it doesn't work but I have not had time to order an adapter to power it on. I was thinking to retrofit a more normal IEC plug on the back. Since it's 100v it will need a step down transformer (probably about $80 on amazon).

As far as shipping, the quote you're seeing is for me taking the panels off the rails and packing them more easily into a smaller box, but then mailing the rails to you. It might be possible for a similar price to keep it all together. I'm friendly, we'll work something out if this is destined to be yours."

This appears to be the first post to feature Iwatsu.

Black Corporation Xerxes MK2 :: Building a Pad from Scratch :: Sound Design

video upload by Harry van Mierloo

"Little sound design session on the Black Corporation Xerxes MK2 to test a lightweight recording setup directly to my phone.

No fancy post-processing, maximizing, review, just me building a pad from scratch on the wonderful Xerxes and exploring various variations of it, to give you an idea of the sound design freedom. The patch is initialized from a basic single saw wave patch and I play around with low pass and band pass filtering for the pads. Later in the recording I add some reverb from the @Strymon BigSky, which always helps on a pad.

Like most synths, a basic patch like this might not immediately sound '5K expensive' without effects, refinement and post-processing. Fortunately this versatile machine can do a lot more and is a real joy to use with all its hands-on control. Some typical Elka-features like Pulse Amplitude Modulation (PAM), sync phase control and oscillator self resonance, add to the unique character of this synth. It's a really enjoyable synth and I feel it's going to be one of my main workhorses.

I love how good a DCO-based synths can sound, and they are usually great for pads. Like on the Matrix-1000 and JX-8P, DCOs are super stable by nature, so imperfections need to be added manually. Apart from tuning tweaks/modulation, the Xerxes has a nice drift control for this.

Enjoy, and next time I'll clean the camera lens, I promise! 😅"

Minimal Synthwave with Flowing Melodies | Passing Train 2025-12-28 by atnr

video upload by atnr

"This piece was created using the ‪@KORG_INC‬ MS-20 and the ‪@teenageengineering‬ OP-1 field.
It is a minimal synthwave composition where steady harmonies are accompanied by an expansive, flowing synth melody.

On the MS-20, delay is applied using the ‪@strymon‬ TIMELINE, followed by reverb from the blueSky.
While performing, the filter cutoff and frequency modulation are adjusted in real time to shape the evolving tone.

On the OP-1 field, a single chord is looped using the ENDLESS sequencer, and the performance is transposed live from the keyboard.
The OP-1 field is connected to the ‪@ChaseBlissAudio‬ MOOD MKII, where reverb and micro-loop processing are used to create lingering, atmospheric tails."

CHROMAGENE - Waveforms

"Sound recorded directly from the back of the synth (No added effects / eq / reverb etc)."

See this post for additional details.

W. PROTEIN - SEQUENCING the WAVE/TABLES

video upload by Alba Ecstasy

"In this video I am passing through (almost!) all waveforms (I’m leaving the last waves for you!), combining them for both oscillators.

This 20 minutes tables and waves variations is almost an authentic Berlin School track, I could only bring some pads and percussions and the jos is done!
And I think this little box will become my main sequence voice!

The sound is crystal clear (some artefacts (I thinks they’re normal for wavetable synths) can be heard, as some processing clicks and pops when changing some parameters - my Blofeld had it too - but all these may also come from a very fast attack and from some wavetables tweaking).
If I'm not changing the tables and the waves, the sound is just fine!
Some distortion may appear because of the output level. Sorry about that!

Both delay and reverb are internal, so as the sequence too (32 steps)."

Eko Ritmo 12 (Italy, 1982) - Vintage Analog Drum Machine Rhythm Box with original pedal

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

via this Reverb listing

"CONDITION: The unit is fully working and in very good cosmetical condition for its age with some minor cosmetical traces of use. It comes with the original intro/fill in and start/stop pedal (super hard to find!). The only thing to report is that the on/off potentiometer (which is the same potentiometer that controls the volume) in this model only works as a volume potentiometer. So, to turn the drum machine on and off you simply have to unplug it! Real vintage gem in super great condition for its age: grab a bargain!

DESCRIPTION: The Eko Ritmo 12 has, as the name suggests, a selection of 12 preset rhythms to choose from. The machine also offers Intro and Fill-in breaks for each of the 12 rhythms.

The rhythms are selected by 6 black switches arranged in a 6 x 2 format. All of the switches have built in red LED's to indicate the rhythm selected.

The rhythms encoded in memory are:

· Bank 1: Waltz, Tango, March, Swing, Ballad, Bossa Nova.

· Bank 2: Cha-Cha, Beguine, Samba, Rock, Disco 1, Funky.

The sound quality of the voicing of this drum machine is very good, especially the Snare, Hi-Hat, Cymbal and Cowbell!

Eko was the Italian brand that produced many legendary instruments. The Company was based in Marche, Italy, in the same area where Elka, Elgam, Farfisa, Crumar, Jen, Siel, Solton, CRB, etc. were born.

This is your chance to get your hands on a super rare drum machine made in Italy!"
