"True greatness comes from within! The Mono Lancet is a compact synthesizer with a big sound, with an uncomplicated user interface and lots of charm.

Oscillators
Two analogue oscillators ensure a solid sound foundation. Oscillator one creates triangle-, sawtooth- and square waves and can be set one octave lower than the second oscillator. The latter produces white noise instead of the triangle wave. The pulse width can be modulated via the modulation wheel (MIDI) and/or an external control voltage source (see “Extension”). The glide generator has a legato mode or (alternatively) can remain permanently active.

Filter
The voltage controlled lowpass filter has a slope of 24db per octave. On high resonance settings it self-oscillates, producing a stable sine wave that can be played in a range of about 2 ½ octaves. Using MIDI the cutoff frequency can be controlled by velocity and/or aftertouch.

Amplifier
There’s a strong VCA inside the Mono Lancet that can be modulated by the ADSR or a fixed organ-like envelope. On demand it can additionally respond to velocity.

Modulation
The classical ADSR envelope generator can modulate the VCO- and VCF frequency and the VCA. The LFO offers rectangle and triangle as well as sample & hold and is a modulation source for VCF and VCO.

Extension
There’s a 25pin sub-D connector on the rear of the Mono Lancet. The optional “Mono Lancet Modular Dock” widens the potential of the synthesizer enormously through numerous in- and outputs for control voltages and audio signals. PWM and filter inputs are just two of these.

note on/off
Pitch Bender on/off (CC 84) - affects VCO pitch (+/- 4 tones)
Modulation Wheel on/off (CC 85) - affects pulse width of the VCOs
Aftertouch on/off (CC 86) - affects cutoff frequency
Velocity on/off (CC 87) - affects VCA
Velocity can additionally be set to cutoff frequency (CC 88)
Glide-Switch on/off (CC 89) - glide only works when playing legato

AM8075SE Athena VCF

AM8075SE Athena VCF Demo by AMSynths
via AMSynths
"Back in the 2004 I replicated the ARP 4075 VCF module using exactly the same design and sold a few PCB's to customers as the AM4075. I also licensed the design to Bananalogue, and you can still buy these modules on eBay all these years later. The licensing deal enabled me to buy a new PC and greatly speeded up my design work, which is all done in Eagle CAD. Whilst the filter sounded good, I wanted to improve and simplfy the design when I started up AMSynths. I also wanted to use slider potentiometers and introduce a HPF - the idea of a Special Edition version (SE) was born.

Athena The AM8075SE filter is the first module to be launched as part of a complete modular analog monosynth. VCO, VCA, ADSR etc will all follow. Athena is the greek god of inspiration.

The Special Edition At the end of 2011 I had a new prototype on the test bench, implemented with matched transistor pairs, reworked LM3900 power supply and cut out the rejection trimming circuit as this was no longer needed with matched transistors. Op Amp buffers before and after the filter core were added, as the one complaint from the original AM4075 was that it was rather quiet as it had no buffer circuits and worked best on 10V audio signals.

I added a 1-pole high pass filter based on the classic Roland OTA circuit rather than the awful design in the Odyssey. Slider potentiometers are used through out and after some adjustments to work on 12V power the VCF sounds fantastic! The matched arrays make a great improvement along with using high quality filter capacitors. The slider caps are the same as in the Odyssey Mark 1 and 2, and they will appear through out the Athena synthesizer (and yes I do have pink caps!).

The moudle went into production in July 2012 and the first batch sold out quickly. Further batches will be manufactured, as there are no rare parts to find.

AMSynths Panel The panel is professionally manufactured in 1.6mm thick alumnium in Germany with black lettering. The module is EuroRack sized and fully compatible with many other EuroRack modular synthesizer systems such as Doepfer."

Grove Audio Big Box for Box 11

via Grove Audio

"Available soon will be a new module chassis for use with Box 11 systems. The new chassis will have an additional 1 3/16 inches of internal depth for a total of 4 5/16 inches. The chassis can be used in any Box 11 configuration. Here is a photo of a prototype chassis mounted in a Box 11 console configuration.

The unit will include two buffered multiples with one in and four out, power indicator LEDs, internal power harness with 11 cables and additional 6 pin DIN connectors for power routing. A coupling adapter will also be available to connect two Big Boxes together to form a 22 MU chassis."

Hidden Clavia G2 Modular Modules

via brunov on electro-music.com

"I found some extra modules in the editor that actually seem to work!

It's a "resonator" module and "driver" module. I don't know exactly how to use them or connect them, you can see them below in the screenshot.

There are some more modules that never made it into the G2, I tried some of them, but not all seem to work. Maybe because they don't exist in the G2 firmware, or maybe I haven't formatted the message correctly.

I wonder what the driver is supposed to do..."
