H.G. Fortune Intros Alphatron Virtual Synth For Windows

H.G. Fortune has announced the release of Alphatron, a new virtual synthesizer for Windows.

Here’s what they have to say about Alphatron:

Alphatron is not just a simple VA synthesizer instead in using a 3rd oscillator with digital waves it does offer a lot more variation. Thus it can do analog style sounds reminding of the old Moog and Prophet days but also merge this with the digital realm in various ways to achieve sounds beyond.

Also this 3rd oscillator serves as sync master for oscillator 2 thus creating a lot more sonic flavours. Amplitude Modulation has got it’s dedicated adjustable output and uses oscillator 2 as main source being modulated either by osc. 1 or 3. Oscillator 1 is a polywave oscillator with up to 5 additional waves, so you might have something like Super Saw(tm), Super Pulse, Super Ramp etc.

Another big highlight of Alphatron is the versatile step sequencer with 8 + 4 pattern slots which can be selected at realtime for instant pattern switching. Setting Note Seq to off it can serve as stepmodulator. The Gate length can be modulated by sources.

Two playmodes: normal with adjustable number of steps or Step Variation which is in fact aonther 16 step sequencer to set different number of steps to be played in succession. Loops can be set to repeat up to 4 times, and two alternating semitone offsets can be set e.g. for each 2nd, 3rd or 4th loop. There are 8 pattern slots per patch and 4 global pattern slots which can be used to instantly change pattern. Current pattern can be copied and pasted to a selectable slot, with the global slots even among patches.

Alphatron is available in a free Basic version and a full commercial version. Details below.
