ModSynthMono is free and monophonic version of ModSynth. Sound is same. powerful synthesizer inspired by EMS SynthiA, Sequential Circuits Prophet-5 and Oberheim Xpander. It has Matrix modulation, usually, menu of matrix modulation is combo box parameter, but this has all pods of modulations. No preset, we recommend you make sound yourself.
Details:
- monophonic synthesizer.
- 2 OSC (Sin, Tri, Saw, Pulse(50%-1% width) wave morphing) Noise.
- 1 Wave Folding (added harmonics and aliasing noise).
- 1 Wave Shaper (added harmonics and aliasing noise).
- HPF 24db/oct Cutoff frequency, Resonance.
- LPF 24db/oct Cutoff frequency, Resonance.
- 1 LFO (SawUp, SawDown, Square, Tri, Sin, Random).
- 1 ADR.
- 1 ADSR ON OFF (if OFF is not infinity, envelop run by loop).
- Matrix Modulation (src: osc2, LFO1, env1, env2, dst: osc1 pitch, osc1 wave, osc2 pitch, osc2 wave, wave folding, wave shaping, HPF cutoff, LPF cutoff).
- There is a portamento and volume control.
Signal Path:
- OSC1 + OSC2 + NOISE → Wave Folding → Wave Shaping → HPF → LPF → Drive → AMP(ENV2).
More:
- Oscillator wave is anti-aliased.
- All controls are on the panel.
- Window is resizable.

The Minisynth series collection consist of three instruments: FRET, GRIT and PEAK.
As an overall concept, Acrobatics simplified controls and packed implementations to the highest grade to push-up users creativity first and give steady look and maximum usability to the three polyphonic synthesizers. A reasonable set of sounds for each synth is included.FRET is an accurate reproduction of phase modulation synthesizers of the eighties: reproduces pianos, basses, organs and bells patches with ease, and it can explore wild and spacey atmos using alternative programming.
GRIT is voted to pulses, PWM and organ-like sounds: uses a proprietary mix of phase distortion principles in order to produce its sounds. It is the dirty of the family, watch out for massive aliasing and punchness.
PEAK is the analogue baby of the lot. Classic acid and house tones are at hand. Here the LFO addresses pitch of a clean square or sawtooth waveform with typical Minisynth series advanced modulation extras.
Common look and feel and standardized location of knobs and switches goes in the direction of helping musician when in a busy musical work, when he/she certainly requires instant access to basic synthesis controls and settings to fit in the mix. The Minisynth series collection is also suitable for educational purposes for its separate interpretations of most important synthesis methods and applications.

MinimogueVA is an emulation of the classic Minimoog but includes additional features such as dedicated Release knobs for the two Contour Generators (envelopes), Tuning of Osc 1, Fine Tuning sliders for Osc2 and Osc3, Aftertouch control, 3 Overdrive sliders: one per oscillator (sort of a chorus effect to help thicken the sound), Oscillator Sync, Oscillator Drift (to emulate a drifting analog VCO), and a fully programmable Digital Delay.
Like the original Minimoog, you can turn Osc3 into an LFO with dedicated modulation knobs for the Osc Pitch and the Filter. There is no dedicated Noise Generator as on the original Mini, but pink and white noise are selectable on Osc 3. All controls are mapped to MIDI CC#s, and you can override the default settings by using the MIDI Learn feature.

The Mini-Vyn is an original virtual analog/subtractive design, entered as a competition piece for KVR Audio’s Developer Competition circa 2006.
Originally started as a learning test bed in trying to create an Odyssey emulation (noting that this project in fact shares no direct relation to Oddy-Free), this instrument has been morphed into a seriously smooth, seriously rich instrument. With the ability to be monophonic as well as polyphonic (and possessing a slightly different tonal quality between the modes), the Mini-Vyn is also an incredibly flexible “bread-and-butter” VA. To set it truly apart, the instrument has a feedback-overdrive circuit of original Roberson Audio design that gives the filter a rich and organic sound when pushed to the extreme.
