Products : StringPort : How It Works



The audio goes into the StringPort through a 13-pin polyphonic output (such as a GK3 pickup or the output on a Zeta violin) and is routed via USB2 into the computer. The StringPort also has a MIDI in to give you control through a MIDI controller or floor pedal.

The StringPort then sends a separate audio channel for each string, along with a summed mono signal and others to the computer via USB2. The StringPort also includes a D13 output to pass through to legacy devices commonly used with polyphonic pickups.

The audio signals leave the StringPort hardware via USB2 and are fed into the powerful collection of bundled StringPort applications. The hardware also delivers processed audio information via balanced line outs, MIDI, and headphone jack.


StringPort’s software suite goes beyond analysis to provide complete flexibility in signal processing applied to the sound. The bundled package includes:

VST Wall

Apply a matrix of VST plug-ins on one or multiple strings in any order.

StringPort: VST Wall

Six-channel phase vocoder bank

Enables a player to polyphonically impose the sonic qualities of his or her instrument onto any set of audio files. Imagine remixing pre-recorded audio using a guitar, and the pitch, direction, and playback speed changing depending on the fret.

StringPort: Phase Vocoder


Apply compression, EQs, pitch shifts, filters, modulation, delay, reverb, and amp simulation to one or multiple strings.

StringPort: Polyfuzz


A unique phase-driven wavetable processor with rich sonic modulation capabilities.


Output in the form of readable and accurate notation or tablature suitablefor use with standard scoring programs.

As if this were not power enough, the software is compatible with Max/MSP and other sound engine software, and can be freely modified and expanded on by third parties and knowledgeable users. The StringPort will also include a special version of Synful Orchestra.
