OXI Instruments Coral - Polyphonic Multitimbral Eurorack Synth Review

video upload by Molten Music Technology

"Coral has 10 sound engines, 8 voices and can be split into 8 parts for multitimbral playing over MIDI. Or use it as a massive mono synth over CV. It has a filter, effects and sockets for modulation. In this extensive review I go through all the sound engines, giving some demos on the range of sounds, and show you how to navigate the interface and set it up into parts. There's a lot of ground to cover."

Baby Audio Introduces BA-1 Soft Synth Based on a Poylphonic Yamaha CS01

video upload by BABY Audio

"BA-1 is a modern re-imagination of a cultish 1982 analog synth that looked like a toy but sounded like a beast. It brings you pure and authentic lo-fi textures that are fast to program and dripping with color."

"BA-1 is based on a portable 1980s synth with a toylike appearance and a gritty sound. Despite its small size, it left a big mark on music history, while still flying somewhat under the hype radar. The original has been used as a secret weapon for bubbly synth textures by some of Sweden’s most successful pop producers of the past two decades. It was also a staple of 1990s digital dancehall and beloved by the indietronica scene for its raw lo-fi quality. The ‘CS01’ - as the original is called - has never been properly captured in software form. So for our first ever synth, we started there.

In keeping with our motto 'it’s an evolution, not an emulation', we modeled the hardware with the greatest possible accuracy, before carefully upgrading it with new and useful features. A second analog-modeled oscillator, FM, polyphony, and more, help to vastly expand the sonic palette of the original. All while keeping its signature sound unspoiled.

Additionally, BA-1 lets you drain the battery, bend the circuits, and use the built-in speaker – for an authentic lo-fi aesthetic that you could normally only get with hardware.

If you know our company, you’ll know that effects are our specialty. So we’ve treated BA-1 with an FX section worthy of its own plugin. The effects chain is inspired by budget 1980s rack hardware and captures the lo-fi charm of the home studio scene of the era. The overdrive is modeled after a guitar pedal, while the delay, reverb and chorus effects are based on cheap, but amazing, digital rack units.

In BA-1, the effects are not an afterthought but an ingrained part of the sonic signature. So tweak, use, and abuse them.

BA-1 is simple, but surprisingly tweakable. We’ve put great effort into tuning all parameters to be in the perfect sweet spot. This results in a rewarding programming workflow where tweaking BA-1 is a lot of fun and you’ll create new patches on repeat.

And if a simple interface is not fast enough, you can always use the smart ‘Re-Gen’ feature. Hit Re-Gen and BA-1 will automatically create new and musically tuned patches with every click."

Being Boiled - The Human League Synth Cover

video upload by Alex Ball

"Following on from my Roland System 100 feature video [posted here], here's a full cover of the Human League's first single, 'Being Boiled' from 1978.

I was very fortunate to receive a copy of the original beat patch from Martyn Ware via Robbie Puricelli. Martyn had passed on that it might need to tweaking and experimentation, which wasn't surprising given the nature of analogue gear.

The patch sheet gave me the pitched noise part and the snare and I found I needed to add a bit of EQ from my mixer to dial those in too. I also had had to adjust the settings in tiny increments for quite a while until it sounded very close. Strangely, I had to use the white noise on my 100 to get it to sound like the original recording as the pink noise that they actually used sounded too dull on mine. Maybe it's the age of the unit now!

Interestingly, they used a technique explained in the 104 sequencer manual where a CV from one of the channels can be used to alter the clock speed. If this is dialled in correctly then the note value can be set for each step of the sequence. This is how they got a 4/4 pattern within 11 steps, instead of 16. As I wanted an exact tempo, I cheated and used an external clock pulse via midi.

A puzzle: After the initial beat, another drum sound joins in. It's a sort of bass drum, but it doubles the snare, rather than providing a typical bass drum pattern. This could have been a manual overdub, but it could have also been done with the other two drum parts because I've seen at least one photo of the Human League with two 102 expanders at this time. Either way, it isn't part of the patch on the original patch sheet.

Next, there's the narrow pulse wave rhythm that appears throughout the song, again, it's not part of the original patch, so it was presumably an overdub. Did they put down a clock pulse at the outset and then use it for synch of a 2nd pass? That's my suspicion.

Finally, if you listen you can hear a track of synth FX running continuously through through song. Often it's ring modulator atmospheres, but there's some definite filter resonance and filter LFO mod tweaking in places. My belief was that someone just sat there and tweaked for the entire song on an available track and they blended it in as a texture and I subsequently found an extended interview with Martyn Ware on the Bonedo website where he indeed confirms that they did exactly that. The thinking was to make it sound more cinematic.

Bass line:
Dead easy - two sawtooth waves on the miniKORG 700S with a little detune, no attack and max sustain ('singing') with no release ('sustain'). The 'sustain long' setting is used.

Roll the highpass filter up a bit and the lowpass slightly higher until it sounds right and make sure expand and bright are engaged for filter mod. That's basically it.

Vocals - double tracked, but I also used a 1979 Boss DM-2 on the send of my mixer for some vintage doubling. I don't know exactly what they did on the original, but it's definitely double tracked at the very least."

Waldorf Discontinues the Pulse 2

via Waldorf

"It’s always sad when we have to say goodbye to one of our favorite instruments. In this case we are talking about one of the best synthesizers that first saw the light of day in 1995 and has inspired many music producers and musicians to this day.

This device was one of the pioneers in the world of music production, offering many possibilities to create unique and innovative sounds. It has helped many artists to turn their musical visions into reality.

The fact that this synthesizer was reissued and improved in 2013 shows that it was and still is relevant and sought after after almost two decades later. Many users have requested that the unit be available again, and it has subsequently been updated with the latest technologies and features to offer even more possibilities.

We would also like to thank all the satisfied customers who use this device constantly and create great music with it."

New Module: Making Sound Machines - Farbshaper. Classic Analog Waveshaper in 4HP

video upload by Making Sound Machines

"Getting ready for #superbooth 2023! Really excited to see all our friends and fellow makers again!

This year, we will be introducing our brand new Farbfilter series, and the best thing is, we have a small batch of DIY kits packed! If you join our workshop at @superboothberlin, you can solder the DIY version with our lead engineer Enrica and be the first to get your hands on one of these modules!

In this video, Enrica is playing the #Farbshaper - a classic westcoast analog #waveshaper for Eurorack, designed to add overtones with two CV controlled stages. This module is a non-linear shaper, and it's perfect for electronic and acoustic sounds, ranging from gentle timbral transformation to colourful wavefolding in 4HP.

In this patch, we're sending a MIDI sequence from Stolperbeats to the @WeAreElektron Model:Cycles, with the audio from Model:Cycles processed through the left Farbshaper. The module gets some extra CV modulation from Stolperbeats' envelope out, generating velocity curves from the drum pattern.

The bassline is a pulse wave from @apolloview9305's fabulous Allscillator complex VCO (kits available from @ThonkSynthDIY ), its pitch sequenced with This is Not Rocket Science's @thisisnotrocketscience3942 Tuesday procedural sequencer - a fantastic module that keeps on cropping up in @DivKid clips. The pulse wave is folded using the righthand Farbshaper, with CV input from TiNRS Tuesday's velocity and accent out.

Enrica is tweaking Farbshaper's Gain, Fold and Pleat parameters. With CV patched, Farbshapers knobs become attenuators for the incoming voltage. The little oscilloscope is the awesome battery-driven Korg NTS-2, which came with a lovely book by @BJOOKS on @KorgOfficial synthesizers.

The Model:Cycles sounds are derived from a factory patch, so shout out to @sm0hm and the Elektron team for the lovely and inspiring FM synth they created and also check out Ess' awesome new max4live stuff at @ForsFM!

family meeting: Roland MRS-2 Promars and Roland Jupiter 4

video upload by ohm_studi_ohm

"Since I just serviced a Promars for a friend of mine I decided to compare it to my JP4.
Both units are fully working, recapped and calibrated. And both are from latter revision with IR3109 filters. Basically they have same motherboard, module board and module control board.

First a quick impro taking advantages of what makes them different: Promars has a second VCO with 2 tuning settings so it can sounds thicker than the JP4, whereas the latter is of course polyphonic and has a builtin arpeggiator and stereo chorus effect.
They share the same CPU and 'compuphonic' technology and have (almost) the same presets.
You can hear when I compare both synths that the presets don't sound exactly the same but this is more a question of calibration and preset values then synth character.
Calibration method are different for the 2 synths and there are slight different adjutements, especially on the filter frequency, width, resonance and hi pass filter setting.
Also i'm quite sure the presets value are a bit different in the JP4 and Promars. Most obvious is the "voice" preset with is one octave higher on the JP4 ! And listening to other presets some a bit brighter on the Promars while other are brighter on the JP4.
But you can observe when I edit the JP4 presets that it's very easy to get the same sound from both unit.

They do get along quite well and their respective particular features make owning the two of them even more desirable."

Sequential Circuits Multi-Trak - recently serviced with battery leak fix installed

via this auction

"Check out the MATRIXSYNTH article on the battery leak fix mod and how it's done. If it's not my Multi-Trak you end up with, you'll want to inspect yours to make sure that's taken care of.

The Multi-Trak has a character that is particularly unique, especially when compared to other polysynths of the mid 80's. Some will immediately think of the matrix editor, a somewhat trendy synth interface at the time. If you can come around to matrix patching, I've found 3 things that mostly distinguish the Multi-Trak: its precocious and self-contained sequencer, the oscillator envelope, and the somewhat snarly Curtis CEM3394 voice chip.

The sound is a bit brash and brassy, sweet, snappy, something like sour candy, but it can be sculpted into lush and hazy sounds, just like any subtractive synth. The Multi-Trak fits naturally in many styles of music; techno, disco, dance rock, hip hop. It's sibling, the Six-Trak, was used on the 2017 album GT Ultra by Guerilla Toss. This classic Sequential Circuits synth certainly boasts an intimidating feature set, but it is fairly easy to get used to. With a bit of patience, you'll find plenty of play and ideas."

video upload by Vintage Audio Institute Italia

"In this video we’re show casing our effects a bit further.
Starting off with room effects:
The Binson Echorec 2 is going strong and feedbacking all over the place.
The Roland Space Eco RE-301 as well.
The red box is an odd one, the Davoli 2K Echo : it’s a mega rare, Italian echo housing a German Schaller Magnetic disc Echo - the same used in Lombardi mixers.
It’s similar to the Binson Echorec 2 in structure, fixed speed 4 punch-in, playback heads but it’s a bit more reliable in sound.

On phasers we’re using the Mooger Fooger MF-103 12 stage phaser on the drums, for a bit of crunch as well.
The Mu-tron phasor II on the clavinet style chords.
And lastly another oddball, the Rotor Monster Compact Phasing - most likely a Vermona prototype of their Vermona phaser, with a few added controls - quite obviously an attempt to esthetically copy the Gerd Schulte Compact Phasing - they’re almost the same size (huge) but sound completely different."
