JX2044 Synthesizer Protoype - Polyphonic aftertouch test

video upload by adamstan84

"#JX2044 Quick test of response to PAT MIDI messages (routed to filter cutoff)."

You might remember adamstan84 from previous posts on the site dating back to 2015.

"#JX2044 is my latest synthesizer project. It's an analog synthesizer inspired by Roland JX8P. The "2044" refers to the filter chip I used - V2044 from CoolAudio, which is a clone of legendary SSM2044.

Here are some basic specs:
8 voices, bi-timbral
2 DCO oscillators with CrossMod (AM) block based on JX8P, but with PWM capability, and with added triangle waveform instead of noise for DCO B.
3 ADSR envelopes per voice - with switchable Exponential/Linear shape
3 LFOs per voice - LFOs can be slaved together for typical monophonic behavior. Seven waveforms - triangle, sine, square, rising ramp, falling ramp, random and noise.
4 pole (24dB/oct) resonant low pass filter (with self-oscillation)
DCO B can be used as source for Filter FM
master HPF per layer, adjustable in 16 steps.
Digital effects section per layer, with 4 blocks:
Resonant filter bank with two modes - "VP330 Human Voice" ("Male" and "Female" presets) and Polymoog Resonator with three adjustable bands.
Stereo chorus with three modes - "JX Slow", "JX Fast" and "StringMachine" - the last one using three delay lines modulated with dual LFOs.
4-stage phaser
Delay/Reverb

I tried to somehow group the sounds, but there are some oddballs here and there in between. Anyway, here are some bookmarks
00:00 Bread'n'butter sounds (pianos, electric organs and other emulative patches)
05:07 Analog classics
13:09 Patches showcasing filter bank from FX section (choirs and brass)
14:12 Odds & ends 1 ;)
15:07 Synth basses
16:08 Noise sweep
16:32 Mostly pads - including some "pseudo-digital" ones, for example...
17:13 "MKS Voices"
18:18 Fantasia ;)
18:54 StaccatoHeaven ;)
20:46 SDS Drums
21:01 Patches using Filter FM

New Organelle S2 - Meditation at Arpeggiator Lake

video upload by Critter & Guitari

"Jam at the lake with the new Organelle S2! Order today! https://www.critterandguitari.com This video was made with the Arp-II patch."

"The Organelle S2 has arrived! From the outside, the S2 features maple keys and sturdy black metal enclosure just like its predecessor, but the insides have been completely redesigned. It now runs on a 1.8GHz quad-core processor — 50% faster than the Organelle S!

There are lots of small improvements too: a new encoder with a smoother feel, easier WiFi settings, and even a redesigned SD card slot that prevents the card from slipping into the device.

The Organelle S2 runs all your favorite patches with ease — and has room to grow. We’re also excited to explore some more advanced possibilities."

NIIO analog Introduces GATED RANDOM Eurorack Module

video uploads by NIIO analog

"GATED RANDOM outputs a random CV level and thru gate probability with every gate input.

The range of the CV output is adjustable between 0 and 10v.

The level of the CV output can be shifted with the SHIFT control or a CV or audio source. The SHIFT control can shift the random level completely to 0v: which sets the probability of a random level of happening from 0 to 100%.

The GATE in is always passed thru to one of two GATE outs with probability control that either follow the gate length or latch/unlatch with every gate to that output.

The SAMPLE input allows an external level to be sampled, replacing the internal noise circuit.

Quality all analog circuitry
LED display of the output gates
LED display of the output LEVEL at 0v and 5v
control over gate probability
control over base LEVEL voltage

RITM-2 Synthesizer (1982) - 1 OSC Clone Moog Prodigy

video upload by LFOstore

"According to information that is actively circulating and being replicated on the Internet, the RITM-2 synthesizer was created in 1982 by Viktor Anatolyevich Nikulin, an engineer at the Kirov Musical Instruments Factory, at the request of a musician friend.

The device was well-received by the company's management, and in 1984, it was put into mass production, which continued for 10 years. During this time, the instrument's design underwent three further improvements. It was the only Soviet synthesizer where all components and controls were housed on a single printed circuit board.

Functionally, it consists of one tone generator, a noise generator, a sound signal mixer (triangle, saw, rectangle, noise), a low-pass filter, two full-format envelope generators (attack, decay, sustain, aftertouch), and a low-frequency modulation generator. It is a portable keyboard instrument weighing approximately 9 kg, housed in a plywood case with a lid.

The front panel had two versions: black and white. The main feature of the instrument, which determined its character, long life, and fame in the professional environment, was its unique and harsh sound.

The production capabilities of the enterprise were quite modest, and only about three thousand instruments were produced over the course of 10 years. RITM-2 was produced exclusively on orders from the administrations of houses and palaces of culture, as well as from leading communist enterprises that had their own musical groups.

During the Soviet period, it was impossible to purchase a rare instrument on the open market, and the RITM-2 was not widely known among musicians who were not affiliated with amateur groups. It was not until after 1993, when the Soviet government's support for amateur music, along with the cultural palaces and the Soviet government itself, ceased to exist, that the RITM-2 synthesizer began to find its way into the hands of professional musicians both in Russia and abroad.

The electronic musical synthesizer Rhythm-2 is a single-voice
keyboard instrument designed for solo, ensemble, orchestral performance of musical works of various genres, as well as for educational purposes and obtaining new sound effects. It can be used both in pop orchestras and at home in conjunction with an amplifier-acoustic device having an input sensitivity of no worse than 0.775. It is possible to use a low-frequency amplifier of a radio receiver, TV, tape recorder. The sound quality of the synthesizer will depend on the quality of the amplifier-acoustic device used.
On the Rhythm-2 synthesizer, it is possible to imitate the sound of classical musical instruments (keyboard, string, reed, percussion) with a certain degree of authenticity and create original sound effects (wind noise, the sound of a passing train, the sound of a sea wave, a shot and the whistle of a bullet).

The synthesizer can be used to play melodies with randomly changing pitch or timbre."

Aelita Synthesizer (1980) - Cyberpunk Ambient Atmosphere

video upload by LFOstore

"Sometimes referred to as the Murom Aelita, the Aelita is a monophonic analog synthesizer manufactured in the Soviet Union in the 1980s.

Although its design seems inspired from American and Japanese synthesizers of the previous decade, with a dark aluminum body[3] and near vertical control panel, the Aelita's looks are distinctive in the details.

They feature large colored plastic sliders instead of the more common rotary dials, and round or rounded push-buttons instead of flip or rotary switches. The vertical sliders are oriented so that their maximum labelled value is at the bottom, instead of the top as is more common. A sole red LED lights up when the instrument is on.

Its hinge-mounted upper control panel can be shut like a piano keyboard's lid, thus protecting the buttons and sliders and preventing accidental settings changes during transportation, and changing the general shape of the instrument to one that is not playable but more transportable.

The keyboard is 3.5 octaves wide and made of 44 unweighted, full-sized plastic keys ranging from F to C.

All controls are labelled in Russian, using Cyrillic script.

The Aelita has 3 oscillators, each with 3 fixed waveshapes (Saw, Pulse and Square), plus a 4th oscillator only active in unison mode, amplitude cross-modulation, a low-pass filter with resonance, one LFO and two envelope generators, all arranged in a fixed architecture typical of subtractive synthesis. It has a maximum range of 7.5 octaves.

It is monophonic, meaning that it can play only one note at a time (although detuning of each oscillator makes it possible to play fixed intervals or chords instead of notes)

It has two special modes: the unison mode creates an unison-like effect on each oscillator (reducing the range as a tradeoff), and the strings mode creates a vibrato-like effect independent of the LFO.

Although of a sturdier construction, it lacks several features commonly found on American and Japanese brand synthesizers at the time, such as: velocity response, portamento, pitch and modulation wheels or levers, settings memory, and (from late 1982 on) MIDI implementation.

Its output is monaural.

Sonic character

Its sonic qualities have been consistently qualified as 'fat'. Other reviewers also call them 'impressive',and sometimes 'aggressive'.There is audible background noise at the output, resembling oscillator bleed."

Ambient ghosts - Vhikk X, 4ms Ensemble and SMR, Elta TSC 12

video upload by Jay Hosking

"Two ambient songs performed live with a eurorack case.

Buy these songs on an album here: https://jayhosking.bandcamp.com/album...

This is why eurorack exists to me. I would never come to these sorts of results through any other workflow or gear, would never stumble on these harmonies or gently cascading notes, would never feel out the song progression on a computer or even with a more traditional hardware setup. There are many things eurorack doesn't do as well, but moments like this make me realize why it's so special.

Please go give the album a spin.

Three voices: Forge TME Vhikk X, 4ms Ensemble, 4ms SMR
