Alphatron was inspired by the idea of creating a synthesizer for bass and high sequences which can serve as a companion to Avatar ST's pads, atmos and soundscapes.

Alphatron is not just a simple VA synthesizer, instead, in using a 3rd oscillator with digital waves of single cycle type, it offers a lot more variation. Thus it can do pretty good analog-style sounds reminiscent of the old Moog and Prophet days but also merge this with the digital realm in various ways to achieve sounds far beyond.

Also, this 3rd oscillator serves as sync master for oscillator 2 thus offering much more sonic flavour. Amplitude Modulation has got a dedicated adjustable output and uses oscillator 2 as the main source being modulated either by oscillator 1 or 3. Oscillator 1 is a polywave oscillator with up to 5 additional waves, so you might have something like Super Saw, Super Pulse, Super Ramp, etc.

Another highlight of Alphatron is the versatile step sequencer with 8 + 4 pattern slots which can be selected in real time for instant pattern switching. Setting Note Seq to off it can serve as step modulator. The Gate length can be modulated by sources. Two play modes: normal with adjustable number of steps or Step Variation, which is in fact another 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 for instant pattern changes. Current pattern can be copied and pasted to a selectable slot, with the global slots even among patches.

Main features (based on Pro version):

1 VA Oscillator with up to 6 poly waves for Saw, Ramp, Sine, Tri, and Pulse.
1 VA Oscillator with single waves as above plus white and pink noise, Sync slave.
1 Sample Oscillator with fairly typical digital waves (single cycle type) with different harmonic content, Sync master.
1 Amplitude Modulation with dedicated output.
1 24 dB resonant Low Pass filter with dedicated ADSR EG, 4 mixable mod sources.
1 VCA EG. Note: Both EG have 3 modes: exponential, reverse exponential, and linear; and optional control for Attack and Decay by velocity.
1 Booster or Exciter selectable.
1 Mystify with three selectable types (Brite, Soft, Dark).
1 BPM synced Delay with adjustable Offset controlled manually or by modsource, Pan.
1 Bass Boost.
1 Pan for undelayed signal.
1 small Reverb for adding some nice flavour.
1 Saturator.
1 main Volume.
3 x LFO, 1 x Duo LFO (with two waves and phase control for 2nd wave), 1 x S&H.
1 Pitch LFO with option to speed up or down the LFO speed.
16 Step Sequencer (with Shuffle) for notes and velocity plus mute buttons for each step. Includes 8 pattern slots per patch and 4 global pattern slots for instant changes.
3 Wheels.
Aftertouch as selectable modsource.
8 Lazy buttons.
8 GUI variants selectable.
128 patches.

Both free and commercial versions are available. The major differences of Basic Free (less features):

Only 64 patches, No Lazy buttons, Only 4 Seq Pattern per patch & 2 global Seq Pattern, 2 voices, No selectable GUI (instead there is a choice of four different dll to download). No patch select on GUI, but a silly scroller reminder not to forget to support the developer.

K700 is a dual synth designed to create rich texture sounds.

Autogun offers 4,294,967,296 (Four Billion Two Hundred Ninety Four Million Nine Hundred Sixty Seven Thousand Two Hundred Ninety Six) presets, just waiting to be explored for their acoustic potential.

Autogun is based on the Ogun VSTi synthesizer that can produce rich metallic and shimmering timbres, although it's not limited to these sounds as Autogun will demonstrate. Ogun's distinctive synthesis engine can generate more than 32,000 harmonics, modulated by high-level 'harmonic mapping' functions. These synthesis parameters have been put under the control of an artificial intelligence, patch creation algorithm, the reason Autogun can deliver such a huge number of presets.

Every Autogun is set to start from a unique preset number, so that each Autogun user is assigned a personal starting preset-address, ready to explore. However, users can at any time, jump to a new location in the preset-space by simply entering a preset number.

With so many presets Autogun needs no programming, every sound is already somewhere 'out there' and just needs to be found.

Key features:

Based on the Ogun synthesis engine.
Enhanced by the Soundgoodizer, (Maximus) engine.
4,294,967,296 presets to explore.
Preset number copy/paste field.
Preset up/down buttons.
Volume control.

Arracis Gold is an Oscillator Stepping Synthesizer. Its most significant feature is the 4 x 8 osc step-sequencer with adjustable gate-length + modulation on gate-length.

With this step-sequencer you can have a quite rhythmical output incl. short blips (stepping among the oscillators in selectable sequence) plus mixing to the normal (steady) output signal for vivid Pad or Atmos. In addition the 2 filters provide further means for tweaking. Finally at the output section there is Spook fx and two delays in series incl. pan modulation for delay and direct out for spatial movement.

Main features (Pro version):

4 PCM wave oscillators with 384 waves in 3 banks with mixable output in groups of 2 (User wave & SF2 files can be loaded too into each osc slot).
4 x 8 osc step-sequencer with various settings incl. gate-length, hard/soft knob, etc.

The Prodigious synthesizer is a Mono/Poly instrument based in the architechture of a famous synthesiser from the past, complemented with a few more charachteristics from other well known machines, all combined into a single powerfull yet balanced, performance oriented instrument.

It is ingredients are: two audio oscillators that can be self modulated by a third non audio oscillator (FM synthesis capability...) one fat 24db lowpass filter with self oscillation capabilities (and with the possibility of being modulated by the second oscillator,flexibility increased), dedicated envelopes for filter and volume contour, a powerful and flexible arpeggiator for those moments where the fingers are simply not that fast (just kidding...), a chorus effect section with three distinctively rich chorus modes (to thicken up things a bit) and to finalize a delay unit to bring out those spacey sounds to the front.

The result - a very temperamental instrument dressed with a graphical work to match.. Last but not least, it is packed with a full set of 128 presets that covers Basses, Leads, Pads, Strings, Keys, Organs (sort off..), Arpegiated and something in between.. and by the way it is fully automatable too. To install, simpy copy the Dll. file into your Vst plugin folder on your sequencer.
