PITTSBURGH MODULAR PHASE SHIFTER MODULE NOW SHIPPING

The Pittsburgh Modular Phase Shifter is a complex, 16 stage, analog effect module designed to expand on the classic swirls, rich swooshes, and doppler effects associated with the phaser.

 

The Phase Shifter has a single 16 stage audio signal path to create a very rich, full sound. Phased audio outputs are tapped from stages 7, 8, 15, and 16.  Stages 8 and 16 each have a mix output that allow the phased signal to be mixed with an attenuvertable dry signal.

 

Four CV inputs, an onboard LFO, and multiple CV routing options allow for maximum flexibility and extremely deep modulation options. The CV inputs are split into 2 groups. The first group of CV inputs controls either all 16 stages or just stages 1-8. The second group of CV input controls stages 9-16 and is switchable on or off. All CV signals routed to stages 9-16 can be inverted. Resonance can be positive or negative and the module will self oscillate in either direction.

 

To modulate the phase shifter circuit, the module includes a wide range low frequency oscillator. The LFO range varies from 1 minute per cycle to well into audio range. The triangle wave of the LFO is hardwired to modulate the frequency of all 16 channels of the Phase Shifter. External modulation sources are handled using 2 sets of CV inputs. Each set includes an invertible, uni-polar CV input that accepts 0v to 5v modulation signals and a bi-polar CV input which accepts -5v to +5v signals. All of the modulation CV inputs can be used simultaneously and can be mixed with the internal LFO to create very complex frequency modulations. Stages 1-8 and 9-16 can be modulated together or independently using the available switches and CV inputs.

 

 

 

The Phase Shifter module has 2 sets of outputs. The first set outputs the signal at stages 7 and 8 while the second set outputs the signal from stages 15 and 16. The numbered outs (7,8,15, and 16) contain just the phase shifted signal after the selected number of stages. This signal is not mixed with the dry (non-shifted) signal. The Mix outs take the phased signal from either stage 8 or stage 16 and mixes it with the dry (non-shifted) signal.

The Phase Shifter is shipping now.

PITTSBURGH MODULAR ANNOUNCES MOVE [208] DOUBLE ROW EURORACK CASE

 

The Pittsburgh Modular Move [208] is a fully featured, dual row, eurorack case and power supply designed to safely house and power up to 208hp of eurorack modules. The double row case includes a linear power supply, sliding square nut rails, and removable lid with a side mounted secure twist latch. When attached, the lid fits over the patch cables allowing a fully patched modular to hit the road.

The Move [208] is powered by a 5.0A AC adapter feeding a pair of custom bus boards. The boards provide +12v/-12v/+5v power rails in addition to the eurorack bus system.

More information on the Move [208] case is available at pittsburghmodular.com.

The Move [208] begins shipping to dealers within North America this week. EU and UK versions will be available soon. Suggested retail price for the Move [208] is $599.

pittsburgh modular announces the Chain Reactor Limited Edition Module

Our second limited edition module, the Chain Reactor is a quadraphonic voltage influenced chaotic waveform generator. The module is available now exclusively at pittsburghmodular.com. Production of the Chain Reactor was limited to 50 modules and once it is gone, it is gone.

The Chain Reactor combines two of our classic VILFO modules with two additional free running LFOs to create an endless supply of chaotic fluctuations. VILFO1 and VILFO2 feature our unique voltage influence control. Voltage influence works differently than standard voltage control, it allows the incoming CV to mingle with the LFO waveforms in interesting ways, creating unique modulations and patterns. The output of each VILFO is a voltage controlled variable waveform that shifts from a triangle to square wave.

The Voltage Influence Circuit

A typical Voltage controlled oscillator works by using a CV input to directly control the oscillation frequency. The more voltage sent to the CV input, the higher the frequency of the oscillator. The lower the voltage, the lower the frequency of the oscillator. Voltage Influence works by using the CV input to attenuate the frequency of the oscillator while at the same time injecting some of the voltage from influence CV input to the feedback loop of the oscillator. Results can vary from subtle to chaotic. Subtle results can be similar to tremolo, shuffle, or soft reset while more extreme settings produce glitchy, rhythmic, chaotic fluctuations in the frequency of the oscillator.

Pittsburgh Modular Announces A New line of Limited Edition Modules


Three years ago Pittsburgh Modular Synthesizers started as a crazy idea to sell a few strange, handmade modules out of a basement. Thanks to your enormous response to those modules we've grown meteorically.

Shipping modules and instruments in large numbers takes a tremendous amount of time and resources. Resources that we can not commit to every idea we have. While we have been working hard to expand and improve our manufacturing capabilities, at heart Pittsburgh Modular is still a small company that remains committed to producing high quality, hand made electronic instruments. Over the past few years, we have chosen to focus our energy on modules that make up the core of our amazing synthesizers. Because of this, we have a lot of concepts and a lot of modules that were designed but never sold. Most of our ideas are too strange to fit in with what Pittsburgh Modular has become and it would be impossible for us to maintain a product line that included all of our designs. Still, we want the modules for our systems so here is the idea...

We are starting a line of limited edition modules as a way to share some of our more esoteric designs with the world. The modules will range from chaotic and noisy, to simple, to over the top.  Each production run will be limited to 50 modules, and each module will be hand signed and numbered on the rear of the panel. All limited edition modules will be available for sale exclusively on shop.pittsburghmodular.com, and once they are gone, they are gone.

We are pleased to announce the Dual Ring, our first limited edition module. The Dual Ring houses a pair of ring modulators with linked inputs and an output mixer, creating unique sonic and signal routing possibilities. The Dual Ring was a request of our good friend Dave Skipper. We were a little skeptical at first but the results prove this was an inspired idea.

The Dual Ring is available now at shop.pittsburghmodular.com

Cell Cases Now Shipping with Improved Power System

CELL [48] And CELL[90] cases are now shipping with an improved power system. The new flexible power rail allows for easier module installs and is +5v and eurorack bus compatible. The new Cell case power system is easier to use. Eurorack modules are installed simply by attaching the power ribbon cable included with the module to the new flexible power rail. The power rail uses keyed headers to ensure a safe and correct connection each time.
