Grp Synthesizer A4 | Kid Gloves

Alex Ball

"The Grp Synthesizer A4 is an Italian analogue synthesizer originally released in 2012.

Combining classic subtractive synthesis with modern desires, it's got pretty tasty spec.

To save the longest video description ever, here's a link to Theo Bloderer's comprehensive breakdown:

In this video I tried to make use of the A4's architecture, whilst keeping things musical. It's very easy with this much power at your fingertips to overcook it and just make either a sonic mess, or a sound that only works in isolation. Hopefully I've struck the balance.

Examples of things I did:
Dual sequence utilising the playback and step repeat modes. I sequenced some chords in one section with oscillator 1 + 2 (tuned a fifth apart) following sequencer A and oscillator 3 following sequencer B.

For the lead sound I also used the sequencer as a modulation source sent to phase synched oscillators and the filters that also had its tempo CV'd from an envelope so that it sped up and down rollercoaster style.

I ran my Juno through the A4 via the external signal in and envelope follower. This allowed me to control the A4 from the Juno, but have the dual A4 filters on it. I also tuned in two of the A4's oscillators to complimentary intervals and they were coming through with the Juno every time it gated the synth.

The main riff was a blend of three oscillators and the ring modulator with a combination of linear and exponential modulation and oscillator sync.

There were also various stereo bass sounds - subby and round, sharp and phat, and driven and heavy. The distortion comes from the synth itself.

I also made some floaty, trippy sounds with the A4 in the middle eight, as well as various FX.

Hopefully this all gives a glimpse into what it can do.

Sunset Synthesizer - Part 3 - Novation Peak, Eurorack and Moog Grandmother Jam

Dune Expectral

All parts in the second set of videos here.

"Be welcome! I am very happy to have you here. This is my third video in the sequence of 5.

This is a challenge, I am looking for new timbres with my synthesizers, but I decided to look for them in different places, in this case it was a wonderful sunset in the city of Sorriso, Mato Grosso, Brazil.

All sounds, modification were created in real time. I used the Moog grandmother to make the bass, the Eurorack modular Vinicius Brazil to create the melodic part, the Novation Peak for the leads, and Pogona 3 by Arthur Joly to create the percussive part, the whole drum is 100% analog.

The melodies are coming through Ableton live only this is digital. And of course this wonderful video captured by La Isla Filmes."

Filter - Summit Series // Novation


NovationTV Summit Series

"In this video, -CALC- takes you through the analogue filter section of our flagship polysynth, Summit. Summit has a pure analogue filter section and it's a very powerful tool, here we explore all sixteen of them (one for each voice) and the different ways you can get creative with them.

With its multitimbral architecture and 16 voices of polyphony, Summit is like two Peaks in one instrument, enabling two completely independent patches to be split or layered across the keyboard, or switched between on the fly. And, that’s not the end of it: the addition of dual filters, greatly extended front panel controls, audio input and the same premium-quality five-octave keyboard introduced with our SL MkIII MIDI controller, put Summit in a creative league of its own.

Kraft Music - Sound Comparison - Korg SV-2, Crumar Seven and Viscount Legend 70's

"Find exclusive Korg, Crumar and Viscount BUNDLES at Kraft Music:

The Korg SV-2, Crumar Seven and Viscount Legend '70s, are all three powerful instruments that offer each a unique set of features, control panel and most importantly, type of sound. Some musicians require that, "certain sound" that really matches with the music or the style they're playing. High gain, slight distortion, subtle rotary and etc, all matter when you are considering which electric piano is the right fit for you. Another thought to consider is the panel layout. If you're a working musician, there's a strong chance you're looking for a very specific set of features and settings placed in a convenient area of the panel for easier access. No screen driving, pressing shift for alternative functions or use of jog dials.

While not meant to be a deep-dive into the difference in sound, we patched together this short sound comparison of the three aforementioned pianos. Each piano closely playing the same piece written and performed by our good friend Ray Tevich.

Take a quick sound check of the Korg SV-2, Crumar Seven and Viscount Legend 70's Electric pianos and consider what are the sounds and features that matter to you! If you'd like, you can give us a all or chat with us at and ask us any questions you have regarding any of these pianos. Our team is composed of seasoned musicians that love to share their passion of music with everyone, and help you with your musical endeavors.

New SSL Serge Dual Slope Generator in MU Format


Synthetic Sound Labs has just released the flexible 1240 Dual Slope Generator (DSG) - a long awaited addition to the MU world - designed in close collaboration with the legendary Serge Tcherepnin.

The 1240 DSG is the ultimate patch-programmable control voltage generator. A Serge Slope Generator is a slew limited unity gain voltage follower whose positive and negative slew rates are voltage controllable. It has an extremely wide range covering sub-sonic to high audio rates. Trigger inputs and pulse / gate outputs extend the slewing functions for use as a voltage controlled (VC) LFO, envelope generator and a variable pulse delay mono-stable functions.

One VC responds roughly exponentially, and two additional VC inputs are routed to individual Rise and Fall slope attenuverters for maximum flexibility and convenience. This newly updated circuit now includes temperature compensation to help eliminate drifting. The linearity and accuracy of the slews allow them to be used for exacting applications such as portamento functions.

The 1240 has two identical slope generators (A & B) - each of which can be set to self- trigger (Loop), or even to trigger each other for some wild modulation and audio
effects. It also has two auxiliary outputs which provide an output that is the greater of A

& B (PEAK), and another that is the lesser of A & B (TROUGH). These are interesting and go far beyond normal summing / mixing.
Among the many functions the 1240 DSG can perform are (x2):
• VC Transient / Envelope Generator - simply started by trigger or gate at TRIG IN.
• VC LFO - The rates are controlled by the Rise and Fall Rate knobs and inputs, and
the slopes controlled from LOG thru Linear to Exponential.
• VC Timing Pulse / Gate generator.
• VC Portamento with separate controls for rise and fall rates, and slopes.
• Envelope Follower (Detector) - The VC decay rate allows the response to be
moved from positive to negative peak detection.
• VC Pulse Delay (Monostable).
• Sub-Harmonic Series Generator. A trapezoidal wave-shape is generated for
sonorous, smooth sounds.
• Audio Generator with variable symmetry and a range into kilohertz regions.
• Non-Linear Low-Pass Filter. The VC slew limiting can progressively turn a sawtooth
wave into a triangle and many variations between. Thus a slope generator can be used as a very interesting low-fidelity VCF.

SSL uses quality fiberglass-epoxy printed circuit boards, precision automated robotics and meticulous hand-crafted assembly assure years of trouble-free service.

Synthetic Sound Labs has been in the analog synthesizer business since 1973. The 1240 is yet another in SSL’s growing line of new synthesizer modules. Proudly made in the USA.

Pricing is $495 US. Available directly from SSL and through NoiseBug, Pomona, CA."

Space Echo RE-201 vs AudioThing Outer Space - Hardware vs Plugin Comparison


"Space Echo Plugin:

0:00 Intro
0:04 Snare - Echo
1:08 Snare - Spring Reverb
1:24 Guitar - Echo"

"Outer Space is a faithful emulation plugin of a famous vintage tape echo made in the early seventies.

As the original unit, Outer Space features a tape echo section with three playback heads and a spring reverb tank.

We have modelled three different tape frequency responses and saturations, along with all the analog imperfections of tape recording/playback.

We have also modelled the ballistic response of the delay rate (repeat rate) which can create eerie pitch shifts (due to the Doppler effect), one of the classic tape echo-based sound effects."

Roland JD-800 Minus Keys

via this auction

"This JD-800 is in rough shape. There's no key bed, so it can only be used as a MIDI module. The left end cap was smashed, and the whole thing got sprayed by some sort of liquid that stained the plastic and etched the aluminum. However, it functions OK. It has been completely re-switched, and the faders have been cleaned. The internal circuit boards are in good shape. Could be parted out or repaired, though end caps and key beds are very hard to find these days. The bottom interior has had rust removed and painted with clear acrylic paint to prevent further corrosion. Because of the state of the instrument it is sold As-Is."

Moog Multimoog Vintage Analog Synthesizer SN 1473

via this auction

"The Multimoog was Moog's response to the ARP Pro Soloist, although a bit late to the game. It was part of a trio of synths that were known as the "Constellation", which included the Apollo (Polymoog), Lyra (Multimoog), and Taurus bass pedal synth. The Lyra eventually morphed into the Multimoog and was designed to sit nicely on top of the Polymoog case, matching the look of it, and interface with it through multiple jacks in the back. It was basically an expanded Micromoog, with an additional daughterboard for the second VCO and amazing touch sensitive keyboard effects that could be routed to sync, LFO, etc. It was the last Moog synth before Bob left the company. It is sort of like a Minimoog with aftertouch capabilities, but has a very unique sound. Check it out on Saga's Heads or Tails "Pitchman" (the bass sound), Telex (lots of tracks), Spyro Gyra (Access All Areas), as well as Kraftwerk's Model off of Man Machine (actually a Micromoog, but same sound)."
