A-Series 1 Modular Synth

The A-Series Modular Synth is the first fully modular synth for Reason, where you can design your synths however you want for whatever sound you can imagine. And because all the modules are mix-and-match, all those Reason effects and devices that you already have can go right inside your custom synth. The A-Series 1 is the first rack extension in series.

(Current version 1.0.4 - see update notes below for details.)

The A-Series Modular Synth is a set of modular synth components to allow you to design your own synth in Reason. The A-Series components aren’t hard-coded together, meaning that the audio and CV signal paths between all the components that make up your synth are completely up to you.

The A-Series 1 is the firsts of two rack extensions to launch in the A-Series. The other is the A-Series 2. The A-Series 1 contains a midi-to-CV converter, a VCO, an envelope generator, a VCA, and an LFO. The A-Series 2 contains a poly splitter, a sample and hold, a noise generator, a VCF, a ring modular, and a mixer.

Modules:

The A-Series 1 rack extension contains the following modules:

A-19SEQ - A midi-to-CV converter, receiving midi signals from a midi keyboard or the Reason sequencer, of from rack sequencers like the Matrix, and converts the signals into CV (note) data and gate (velocity) data. These signals can then be routed to control any other device, such as a VCO or envelope generator.

A-11VCO - A voltage controlled oscillator generating four waveforms - saw, square, triangle, and sine - all at the same time. The A-11VCO has a 7-octave range with coarse and fine tuning, can accept and mix a second pitch modulation signal to create FM-like effects, and can modulate the pulse width of square waves. Each parameter can be controlled by CV input.

A-14ADSR - An envelope generator with three speed ranges and standard attack, decay, sustain, and release parameters. Each parameter can be controlled by CV input.

A-13VCA - A voltage controlled amplifier allowing multiple signals to control a sound’s gate shape, with two gain CV ins and a two-in audio mixer. Each parameter can be controlled by CV input.

A-14LFO - An LFO with four signal waveforms - saw, square, triangle, and sine, three cycle speed ranges, with both free-running and tempo-synced cycles, and pulse width modulation of the square wave signal. Each parameter can be controlled by CV input.
