This is a collection of voltage-controlled synthesizer modules, intended for patching together into instruments. It was inspired by the Nord Modular G2, still my favorite modular synthesizer.

To create a “patch”, paste the modules into an ensemble and wire them together.

All inputs and outputs are “voltages”, and follow conventions commonly used by modular analog instruments. Pitch inputs are calibrated in 1 volt/octave. Oscillator and LFO outputs are +/- 10 volts peak-to-peak, and envelope generator outputs max out at +10 volts. All inputs can operate at the audio sample rate. While this consumes additional CPU resources, it means that anything can be connected to anything.

I want to thank Jonathan Style for creating all of the custom panel elements.

The upload contains:
* Ampere.ens – An ensemble that includes one instance of each module.
* Example Instruments – A folder that contains some instruments created with the modules.

The example instruments are:
--Hammond organ emulator
--Modal synthesis bells
--Physically modeled guitar
--16-oscillator super saw synth

At http://electro-music.com/forum/download.php?id=19922 is a zip file that contains "AmpereV6 Modules", a folder that includes all of the modules as separate macro files, grouped by type. Copy this folder into the default Macro path, and it will appear in Reaktor’s macro browser.
