Pittsburgh Modular Foundation 2.0 Analog Eurorack Modular Synthesizer

via this auction
The Foundation is a fully modular, eurorack, analog synthesizer. A patchable system styled after the great monosynths of the past with no hardwired signal path or fixed voice architecture to restrict creativity. Driven by two wide range analog oscillators the Foundation produces a huge, warm sound that can't be matched by digital or VST synths. All of the elements of a classic voltage controlled synthesizer are available as an open, patchable, modern synth.

The Foundation is a "complete voice". It contains all the modules needed to produce a wide variety of complex sounds such as monster analog bass, cutting leads, evolving pads, and short percussive hits. All of which can be controlled directly using the Foundations' 42 knobs and switches then played with any standard Midi controller. The Midi module included in the Foundation allows for monophonic / duophonic / and dual monophonic patching for maximum flexability. The Foundation is also fully compatable with Expert Sleepers Silent Way software plug-ins¹.

An unpatched Foundation offers a clean slate for sonic exploration and sound design. The open format of a modular synthesizer allows for greater control and a deeper understanding of synthesis. The Foundation is comprised of a heavy duty eurorack case and individual eurorack modules designed to work together and as part of a larger modular system. Modules within the Foundation can be rearranged easily or replaced as a system grows or individual needs change."

SERGE 2 Panel Paperface w/ psu

"Here is a very rare, early, kit-built Serge. One panel has a dual Negative Slew module, two Programmer modules, and a triple Bi-Directional Router. The second panel includes a module labeled "Dual 7486" (a ring-mod or dual VCA or both?), Sequencer, Dual Processor, Envelope Generator, dual Positive Slew, and dual Negative Slew. The amazing thing about the slew modules is that they can be cycled for use as oscillators (audio or LFO) or triggered as envelopes--they are precursors to the infamous Serge DSG. The Envelope Generator can be used as a pulse-width-modulated oscillator. The Sequencer is a gate sequencer that can be used to clock the programmer to make a CV sequencer. These two panels can serve many purposes: 7 oscillators or LFOs or a bunch of simple envelope generators, or anything in between. They can easily be used as an instrument on their own or interfaced with other modular gear.

Everything works on these panels except the the top half of the Dual Processor, which won't pass signal. The pitches I was getting by cycling the Slews were sometimes unstable and quirky, but sounded good otherwise. The power supply gets pretty warm. I'm sure you've noticed that someone built these panels with 1/8" (3.5mm) jacks. Notice the switch between the two programmers; it switches between the two top rows of the Programmers, sending to the jack on its left. The ground wire on one of the panels doesn't have a solder lug, but it is still easy to attach that wire to the PSU. The pots may benefit from a cleaning, but all work.

Since this is a vintage kit-built synthesizer it is sold strictly as-is..."

BassBoy - overview


Published on Sep 27, 2012 by alexfox101

"BassBoy is a monophonic digital MIDI controlled bass synthesizer. Device receives all information via MIDI input. The unit consists of oscillator which generates SAW & SQUARE WAVE using 16-bit band-limited wavetables, thus making the number of harmonics limited. After that, the signal itself goes through a simple implementation of MOOG filter, whose frequency range is chosen by MIDI commands and which is affected by the level of the envelope. The filtered signal then comes to the controlled amplifier, which creates the signal shape, and in the end through DAC (WM8762) and pre-amp circuit goes to the audio jack 6.35mm.

Raspberry Pi UI Update

via the Raspberry Pi Blog
(see the before pic here)
"I think this is done, and the design exposes enough underlying modulation flexibility to get lots of interesting sounds out of it. Now I need to tweak the code to represent all the new LEDs and tweak the existing LED positions in the overlay geometry to align with the rendered underlay. Should be done before the end of Saturday, tomorrow I'm on other stuff.

Note the VCA block, 'EG2=>A' and 'EG2=>B' - this is to allow stealing of the noise EG (EG2) to allow each oscillator to ramp independently. Both OSCs (in fact everything) is still envelope shaped by EG3 right st the end of the signal chain, but earlier on during modulation EG2 can now be applied to one of the OSCs. This could give some really interesting richness if a more harmonic-rich wave is ramped up slightly more slowly than the other, harmonic-poor wave, to add yet more movement to the attack. Experimenting with this by pulling on the OSCB slider while hitting notes leads me to believe that this could be a killer feature.

Here's an interesting observation for those who can count - notice that every modulation template (the stuff enclosed by blue lines on the right) has 16 options - 2x2x4 or 4x4. So every template is just one of 16 possibilities, 7 templates (VCA, phase, pitch, filter, LFO0, LFO1, MOD/CHANPR) so just 7 switch statements and a tiny burst of multiply-accumulates and I'm done. So the new modulation matrix code should be way, way quicker than the old one. I just need to write it ..."

New Phonec VST Funk Audio Demo

Phonec VST Funk by ramjetproductions

"Audio demo of new VST software synth from Psychic Modulation.

7 instances of the synthesiser in track with no added effects on bass, chords, pads or stabs. Drums from Cubase Groove Agent and Reel People v 3 drum samples. Real guitar by me. All synths played with Roland Midi Guitar GI-20 interface. www.ramjetproductions.co.uk"

"Phonec is best described as an 'analog flux synthesizer'. Inspired by the mystique of video logo synth scores from worn out VHS tapes, Phonec was primarily designed with character in mind. However Phonec is capable of producing a wide range of sounds such as vintage analogue tones, lo-fi synthscapes, ethereal pads, minimal techno sequences, and synthwave leads and basses. Phonec has an intuitive GUI that attempts to strike a balance between form and function, making it a very usable tool that can be a real inspiration to work with. Apart from it's unique character and smooth workflow, Phonec has several interesting features that set it apart from the crowd. Here is a brief overview that highlights the most important aspects:

Dual oscillators that can be combined in various ways
Analog style oscillator drifting
A unique Melt feature that adds instant character to any patch
Arpeggiator
Accent Sequencer
3 LFOs (2 monophonic, 1 polyphonic)
HFO (High Frequency Oscillator)
2 Modulation Envelopes
Echoshifter Delay Unit
Universal Value Display
Double Click Parameter Reset
128 presets"
