AMSynths AM8705 Dual ADSR Envelope & AM8060 JP6 Multi-Mode VCF

via AMSynths

"This module is a Dual ADSR similar to the envelope generators in the Roland 700 and 100M modular analog synthesizers. The AM8705 contains two identical traditional ADSR format envelope generators with variable Attack, Decay, Sustain and Release. The module uses 30mm travel slide potentiometers and has toggle switches to switch between 2 different set of timings - slow or fast."



"This module contains two envelope generators each with 3 timed stages: Attack, Decay, Release. The Sustain control adjusts the level to which the Decay time reduces to. Both ADSR's are triggered together by an internal gate signal from the standard Doepfer 16 pin bus, or a front panel push button (MANUAL GATE), or individually via a gate signal connected to the front panel Gate jacks (GATE1, GATE2).

The standard duration of each stage is 10 seconds, but each ADSR can be switched using the TIME toggle switch into a fast timing 1/10 the duration. This enables fast envelopes to be generated. Two identical control voltages are available for each ADSR, making it easy to patch an ADSR into both a VCF and VCA simultaneously. The gate signal is displayed for each ADSR via a dedicated LED. Each ADSR generates a control signal from 0V to +10V.

There is a Red gate LED for ADSR1 and a Blue gate LED for ADSR2. The toggle switches have colour coded caps (Blue and Red) and the single gate switch is a Red push button button."


"This module is a replication of the Jupiter 6 voltage controlled filter which comprises two 2-pole OTA filters in series, and was launched in 1983. Each 2-pole filter can be switched into either Low Pass or High Pass modes providing three VCF modes all with variable resonance:

24dB Low Pass Filter
24dB High Pass Filter
12dB Band Pass Filter

This voltage controlled filter has a more aggressive sound than a simple 4 pole OTA based filter, along with a lot more flexibility...

This module is a multi-mode voltage controlled filter with front panel controls for adjusting the Cutoff Frequency and Resonance as well as the level of 2 control voltages and 3 audio signal inputs. There are six 3.5mm jack sockets on the right of the front panel; the filters audio output, 2 control voltages and 3 audio inputs. The filter topology can be adjusted using two front panel latching push buttons.

The filter has two 2-pole OTA filters in series, and the blue and grey push buttons select from 4 filter modes, each sounding different:

24dB Low Pass Filter - Blue and Grey OUT
24dB High Pass Filter - Blue and Grey IN
12dB Band Pass Filter - Grey IN and Blue IN
12dB Band Pass Filter - Grey OUT and Blue IN"

AMSynths May 2013 Newsletter - AM8044 Cascade VCF &VCA & More

"Newsletter May 2013
Latest News
Spring has arrived at last in the UK with at least one sunny day! At AMSynths we have been busy launching new modules and catching up on the backlog of reservations. Here is the latest news, check our web site here:

Module Plans
The popular AM8012, AM8075, AM8071 and AM8109 filter modules are in production and shipping to customers, along with the AM8328 Miarge Filter which we launched in January. The AM8044 VCF and VCA has now been launched with stock in the webstore. This module uses the SSM2044 chip to produce a very smooth filter and a simple VCA has been added after the VCF, which can either be used as a final level control or a 10V positive going envelope generator can be patched in.

The Dual ADSR AM8140 is the next module to go into production during May, along with the AM8060SE Dual State Variable Filter - with plenty of back orders to fill. The testing of the AM8027 Dual VCO has completed and the next stage is to build some production versions in June before we officially release the module for customer shipments.

PCB's and Panels
We launched PCB's and panels for customers that wish to build their own modules back in March, and they are proving very popular. We have a growing inventory in the web store, covering most of the Eurorack range. We have online Project Notes with BOM's and guidance on building and setting up.

E-mu Modular
One of the AMSynths projects for this year is to build an E-mu Systems Analog Modular synthesizer using panels from Exclusively Analogue, with some original E-mu PCB's and some re-designs that I have completed. You can read more about the project as it progresses over the next few months on our Blog."

AMSynths Update: AM8060SE JP6 VCF & AM8044 VCF & VCA

AMSynths Newsletter July 2013

"Latest News: Over the last few weeks we have been busy building modules for customers, as well as completing the testing of the exciting new AM8060SE JP6 filter, and a new VCF, HPF & VCA module the AM8105. Stock levels in the web store will start increasing again, and we are building AM8109 JP8 VCF, AM8140 Dual ADSR, AM8044 and AM8328 VCF's over the next month. So if you are after one of these modules, they will be in stock.

We will launch a very limited run of AM8320 VCF modules that use the CEM3320 configured to replicate the sound of SCI Pro One in late July. Details are here. If you wish to reserve one just reply to this newsletter. And finally, during August we should get round to launching some VCO modules, you can see the E-mu Systems Simple VCO that we have redesigned and replicated as the AM2210 here. Next projects to complete in the summer are both a Roland JP8 VCO and the ARP dual Athena VCO.

Best Regards
AMSynths"

"AM8060SE JP6 VCF
This new module is being launched in July with a batch of 10x modules going out initially to customers who have reserved the module. This is a dual SVF filter with low, band and high pass modes controlled by original Roland JP6 switches. The module goes into self oscillation at high resonance setting and we have carefully trimmed the design to ensure this is controlled, as SVF's can produce a huge signal level when oscillating, The original AM8060 used hard to locate IR3109 chips but we are now using SSM2164's which means we can build all the modules that customers want. Sound demos will be up on the web site soon."

"AM8044 VCF & VCA
The AM8044 module has a 4-pole low pass filter, as used in the Korg Poly 6, followed be a precision VCA. Just connect a couple of VCO's and a Dual ADSR (lie the AM8140) and you have a complete synth! A nice warm filter coupled with a very useful VCA, buy one in the webstore today at 125 GBP. Here is the link."

Amsynths AM8171 Quad Sequential Switch

video upload by O.Z. Hall

"When Roland developed the System 100M they created a quad signal gate module, the 171, which also had a ton of multiples. The AM8173 module contains the same four signal gates built with modern components, and an onboard LFO clock, making it a very useful sequential switch, for both audio and CV signals.

AMSynths Update & AM108 Jupiter-8 / Jupiter-4 Filter

I just received the AMSynths newsletter. The latest news is that the AM8319 Ring Wraith will be in production in early January, and the AM8005 Filter Cube, AM8047 UAF and AM8027 VCO will follow. The newsletter also mentioned their current modules which you can find on their website.

The one module I realized I haven't posted yet is their AM108 Jupiter-8 and Jupiter-4 filter pictured here.

"This module is replication of the Low Pass Filter from the legendary Roland Jupiter 8 and 4. This is a 2 and 4 pole OTA design that Roland first used in the Jupiter 4 in 1980, replacing a discrete version of the filter which took up more PCB space.

This is a warm sounding filter with smooth frequency control and a resonance that gradually increases up to full self oscillation, a sound very reminiscent of the early 1980's.

The difference between 2 and 4-pole modes is not dramatic, with the 2-pole mode providing a more gradual cutoff slope and silky sound."

Other modules in development include:

AM8012 ARP2600P transistor VCF
AM8027 ARP2600P VCO
AM8044 Cascade LPF and HPF
AM8047 ARP2500 Universal Active Filter
AM8475 Odyssey VCF and HPF
AM8706 Titan Modulation Source
AM8280 CS80 Dual SVF
AM8104 Roland JP VCF + HPF"

New AMSynths AM8109SE Low & High Pass Jupiter 8/4 Filters Eurorack Module

"This module is replication of the Low Pass and High Pass Filters from the legendary Roland Jupiter 8 and 4. This is a 2 and 4 pole OTA design that Roland first used in the Jupiter 4 in 1980, replacing a discrete version of the filter which took up more PCB space.

This is a warm sounding filter with smooth frequency control and a resonance that gradually increases up to full resonance, just before self oscillation, a sound very reminiscent of the early 1980's. The original Jupiter 8 filter did not self oscillate, and we have retained this configuration. However the customer can set the filter to self oscillate by adjusting a PCB trimmer on the rear of the module.

The difference between 2 and 4-pole modes is not dramatic, with the 2-pole mode providing a more gradual cutoff slope and silky sound. The high pass filter provides a gradual cutoff of low frequencies.

The AM8109SE is a new version of the 2010 AMSynths design, with slide potentiometers and a skiff friendly module depth of 35mm.

Eurorack Module: 14HP wide
User Manual: AM8109 Quick Start Manual

This module is an accurate reproduction of the Jupiter 8 low pass voltage controlled filter, using the AS3109 OTA chip in the filter core, as well as the high pass filter that uses an AS662 chip. The design has been updated to use modern components with high quality capacitors in the signal path. It delivers a very warm and smooth sound.

There are front panel sliders for adjusting the Cutoff Frequency and Resonance of the low pass filter, and level control of 3x control voltages (MOD, ENV and KYBD) and 2x audio signal inputs. The high pass cutoff frequency is adjusted using a rotary potentiometer with an original Boss coloured control knob.

There are five 3.5mm jack sockets at the base of the black anodised 2mm front panel;
2x audio inputs
3x control voltages
1x audio signal output
There is an audio output jack at the top right of the module. The slope of the filter can be switched between 2 and 4 poles using a small slide switch, and the envelope CV signal can be inverted using a second slide switch.

The module comes with a set of M3 mounting screws and washers, and a standard Doepfer power cable."

AMSynths SUPERBOOTH Module News - April 2022

"Getting Ready for SuperBooth 22

We are hard at work developing new modules for launch at the best synth show of the year - Superbooth 22. We will be announcing the red faced AM8101 filter [posted here], a replica of the low pass filter in the Roland SH-101, as well as the AM8102 SH-2 style filter [below].

The AM8109 and AM8060 Jupiter filters are being relaunched - 10 years after they were introduced, with Special Edition and slim 10HP versions. AMSynths will also be announcing SH-101, Jupiter 6 and 8 VCO's to pair with these filters alongside the current Jupiter 4 VCO and VCF."

This module is faithful replica of the filter from the legendary Roland SH-2 that was released in 1979. The AM81012 is a fantastic sounding 4-pole low pass filter with that unmistakable Roland filter sound in a narrow skiff friendly, Eurorack module.

The module use an Alfa Rpar AS622 chips in the filter core (BA662 clones) and high quality polpropylene filter capacitors. The design includes buffering Op Amps to interface to Eurorack modular levels. The filter does not have Q compensation but the signal level does not decrease dramatically with higher Q settings. The resonance is smooth and controllable into self-oscillation, and the filter will oscillate from 20Hz to 20kHz.

There are slide potentiometers (with LED's) for adjusting the Frequency Cutoff, and the frequency modulation from Keyboard, LFO and Envelope CV signals, There are rotary potentiometers for adjusting the mix between two audio inputs and Resonance. There is a small slide switch to select whether the envelope CV input is Normal or Inverted.

The AM8102 is hand built with high quality components, including Wima polypropylene capacitors, Alpha potentiometers, and TR808 style control knobs.

There are six 3.5 mm jack sockets on the front panel:
2x audio inputs
3x frequency CV inputs
1x audio output
The module comes with a set of M3 mounting screws and washers, and a standard Doepfer power cable.

NAMM 2020 - Introducing System 100 - Behringer Modular Synthesizer

Published on Jan 16, 2020 BEHRINGER

"Introducing eleven new Eurorack compatible modules – all of them authentic reproductions of original “System 100M” circuitry from 1975. With ultra-fat oscillators and creamy filters the sound became famous in the early 80s used by artists like Depeche Mode, Human League, Tears For Fears but also Vangelis, Tangerine Dream and even Aphex Twin.

If you’re into super-fat bass sounds, in-your-face leads or flowing soundscapes, definitely check them out! All modules are incredibly feature rich, have tremendous patching capabilities and a lot of them come with dual function, like:

- 112 dual oscillator with 3 waveforms, PWM and two sync modes
- 121 dual filter with 3-channel mixer per filter
- 130 dual VCA, again with dual 3-channel mixers
- 140 dual envelope has 3 outputs per ADSR plus a built in LFO that can be triggered and phase synced
- 173 gates module comes even with four gates that can switch audio and 6 quad buffered multiples
- 297 has a dual portamento controller plus two independent CV mixers
- 150 brings a ring modulator, 2 noise generators, syncable LFO and a sample and hold generator
- 172 module delivers a 6-step phase-shifter, an analog delay, an LFO and a gate delay
- 305 is an output module a four-band parametric EQ, a 4-channel mixer, line and separate headphone output and even a tuning oscillator
- 182 there is a powerful analog sequencer with either dual 8 steps or 1-16 steps and tempo, portamento and gate time controls
- 110 is a complete synth voice with VCO, VCA and filter in a single module

#NAMM2020"

Update: Word is this might be an AMSynths joint project. From their website:

"Behringer Partnership In June 2019 I joined forces with Behringer to design analog synthesizers that will be manufactured in China and sold to customer across the world. I am working on a number of projects which I will let Behringer announce when they are ready. AMSynths is continuing to grow with more Euro Rack modules being manufactured, as well as complete synthesizers like the SH05 and Jupiter One. In 2019 I started to restore vintage music gear, and you will see the repair stories in my Blog. I am also creating videos of my modules and the vintage synths that they emulate."


Update: some product sheet scans in in via Soviet Space Child and a note on one of the forums from Uli.

"I like to share with you the initial drafts of our M100 Eurorack Series.

These are 13 MID's or concept documents we create for every single product as part of our PLM (Product Lifecycle Management) process before we hand them over to our R&D departments for development.

We haven't decided yet which of these modules we will actually produce as it is important that we achieve a certain production volume.

As usual do we appreciate your valuable feedback which will give a better indication of validity of these products.

Thanks!

Uli"
