"A little improvisation with two Delta CEP A2 synthesizers. You will get an impression of the new Performance Step Sequencers. Allows for adding and removing notes at all positions of the sequence during playback & transpose.

In the beginning I set the left Delta into hold mode. That plays a note or chord until a new note or chord is played." Modular Power Supply, Oscillator, MIDI Interface, Envelope Generator

Xer Mixa stereo mixer/stereo aux outs and Expando Expandi CV expander

video upload by Noise Engineering

"Xer Mixa and Expando Expandi are available now:

0:00 Intro
1:44 Panel and controls
3:45 Screen controls
4:47 Screen menus
6:53 Expando Expandi
8:52 Channel controls

Xer Mixa is a 32 HP all-analog digitally-controlled mixing powerhouse! 8 stereo-paired inputs, 2 auxiliary loops, and a stereo-paired output, tactile controls, and a 100% analog signal path with low noise and crosstalk, pristine sound quality, and ultra-high headroom. A built-in analog leveling amplifier is great for adding some punch to your mix. A digital control interface harnesses the true power of hybrid design, allowing for state save and recall, per-channel pan law and pre/post send settings, multichannel editing, and MIDI I/O.

Xer Mixa features 10 stereo-paired input channels: 8 interactive fader-controlled channels and two aux inputs. All 10 inputs feature clickless mutes. The screen makes configuration of per-channel pan-law settings, pre- or post-fader sends, and channel and MIDI CC routing simple and intuitive. Save your settings in one of seven preset slots for easy recall for your next set or session.

We designed Xer Mixa to be as compact as possible, with a streamlined and compact-yet-usable interface. However, if you’re looking for CV control, the 4 HP Expando Expandi adds 8 freely assignable CV inputs to the Xer Mixa. Connect up to two Expando Expandi to Xer Mixa for easy CV control over channel levels, pan, aux sends, and more. Xer Mixa and Expando Expandi are also available individually.

Xer Mixa can also be oriented with the jacks at the top or the bottom: a simple system setting inverts the screen for easy customization to fit your rig. And despite its extensive I/O, Xer Mixa clocks in at just 32 HP. Whether you have a massive studio rig or a compact performance system, Xer Mixa is the perfect choice for a tactile, expressive mixing experience."

ASM Hydrasynth - "Blockbuster" (40 Exclusive Presets)

video upload by LFOstore

"A powerful sound that permeates the whole body and causes shivers - this is how you can characterize the new powerful soundset from LFO Store! This is a real blockbuster, in which each character plays his role in a way that surprises listeners to the core. The well-known sound designer Otto K. Schwarz prepared something completely new, revealing Hydrasynth to its maximum potential!

Each preset here has a modwheel assigned, as well as up to 8 modulation knobs, which will allow you to modify and transform sounds beyond recognition, getting a complex design. At the same time, many sounds have a multi-categorical nature, that is, they can be used as leads, or as plucks, and even as drones. In this pack you will find many effects and soundscapes, as well as cosmic leads, soft exhilarating pads, intriguing plucks, humming basses and much more!

These presets are especially good for soundtracks, however, suitable for various styles of music - for ambient, electronic dance music, futuristic experiments or even creating a retro flavour. Get ready to take your compositions to the next level!"

Solina String effects demo: Filters, phasers, drives and dirt

video upload by Richard DeHove

"The Solina's raw sound is not like your standard synth so it tends to react differently to effects. I tried lots of different effects and picked the most interesting to show here. First up was the Erica Synth AcidBox III which, surprisingly, was an excellent match. Using the AcidBox with full resonance was fun and would sound even better with stereo delay but I wanted to keep things to just one effect at a time here. Perhaps the AcidBox works so well because of the lack of controls on the Solina - suddenly the Solina gets an LFO, filter, resonance, input drive and envelope follower.

The phaser test with the EHX SmallStone, Phaser 95 and PH-1r I also found very interesting. For me the Ph-1r had the richest sound and the SmallStone was identical to the onboard phaser.

In the drive, disortion and dirt department the Glove and B3K had their moments while the Geiger Counter ranged from mild to total destruction and some bit crushing at the end.

I also included a short demo with the Boss Slicer, but that thing requires several hours discussion just by itself. Where I'm playing a chord with one note I'm actually triggering a Cthulu chord player in the DAW. Most chords are taken from a custom import of the main string line from Bruckner's 7th.

"Very rare original Oberheim SEM (Synthesizer Expander Module) from the 70's.It has been fully serviced by Bell Tone Synth Works in Philadelphia, PA, in August 2022 and works beautifully! As usual, they did a wonderful job! The enclosure has some marks but the module itself is in excellent condition. The only thing that is not functional is the Midi retrofit but I believe this could be fixed easily in case needed. Other than that it works as a CV/GATE module exactly as expected and sounds great! (note: it was originally 240 volts but was converted to 110 volts by Bell Tone)."

1970’s RMI 368X oscillator piano/harpsichord

via this auction

Some pics of the inside.

"Very rare, 4 digit serial number (8640) Rocky Mountain Instruments 368x. This is a chance to own a never-been-emulated electric piano just like one Ray Manzerek played with the doors. While not yet as famous as other keyboards from the era like the fender Rhodes it Vox continental, the RMI was nearly as prolific featuring in everything from country rock ballads with Steve Earles band to Broadway being one of Sondheims own early electric piano choices.

This example is in fully working order, though showing signs of corrosion around the leg bases and some key posts. there is general wear and tear as to be found on a previous session instrument And a few keys seem slightly out of tune, though this reduces with proper warm up time."

Z-Tronics Z-Midi Interface

via this auction

"The Z-tronics system is a stand-alone system and does not in itself incorporate MIDI signals for output to external MIDI devices such as Synthesizers and Sequencers for generating external electronic sounds or for Recording and Playing actual performances. The Z-MIDI interface was developed to interface at the data level and may be easily added to any Z-tronics system, old or new. Connection requires the two timing signals plus one wire in and out per manual.

There are two models available. Z-MIDI-1 provides one MIDI channel in and out, and is useful for adding a dedicated MIDI sound module for one voice such as a Piano. Z-MIDI directly supports the PianoDisk (c) in a real acoustic piano, or any MIDI Sound Module generated voice.

The Z-MIDI-1 also supports stand-alone uses such as adding a pipe organ chest to ANY keyboard instrument having a MIDI Out. A special version of the Z-MIDI-1 may be installed to operate real Chimes or Carillon, automatically ringing the hour and playing MIDI files (such as Hymns) at programmed times of the day.

Z-MIDI-16 is a full 16 channel OUT, 12 to 16 channel IN module which supports BOTH a Sequencer for Record/Playback AND a separate Sound Module. MIDI Sound Modules may be unified or coupled, or not, as desired. While a factory configuration supports Record/Playback for up to 8 manuals (including pedal and second touch) and Sound Module support for up to four manuals, these defaults may be customized for special installations. An optional Human Interface keypad and display enables preset voices to be selected, and other operating parameters changed. MIDI presets may be operated from the combination action.

The Z-MIDI Interface does not process signals normally used to play the organ, and thus does not affect the reliability of the system."

Lights Visualizer by

video upload by Cinematic Laboratory

"I picked up two Light Visualizers on Dutch Modular Fest last saturday. They are made by Amsterdam based Veski Modular. For me, personally, they add a lot of value to my case. The spectral visualizer is really useful if you own a Spectraphon , but it also provides a valuable tuner and tons of metering options. Highly recommended for 'pimping your ride'."

Vaski Lights is a graphical display for your sound in 2 HP.

Also available in silver.

Led display that responds accurately to sound and CV signals. Stereo input and multiple visualization modes let you monitor and design the music you play in a new way! The narrow module fits anywhere: place it next to a synth voice, or on your master output. Keep your levels in check and see the spectral content of the audio stream.

The second jack can be reconfigured as a pass-through output for a mono input signal."


video upload by Stefan Tretau

"SPM is a 3-Channel Mono Mixer with three volume potentiometers. The gain per channel can be adjusted with trimmers on the board, making this mixer suitable for line and Eurorack levels.

In addition, you can pan channel 1 and 2 with the SPREAD potentiometer and thus spread both channels in the stereo field to the left and right in opposite directions. In the centre position, all channels are panned to the centre. If you turn the potentiometer to the left, channel 1 is panned to the left and channel 2 to the right and vice versa.

This is very useful to quickly clean up a mix and widen the sound spectrum in the stereo field."
