GVA-1 Virtual Analog Synthesizer
A virtual analog synthesizer could not miss from this large collection
of high-quality real time synthesizers. The GVA-1 is a subtractive
synth featuring two sync'able oscillators, two filters in series,
feedback input, three envelopes, two LFOs and four modulation
matrices. This is not a simulation of a specific existing synthesizer but
we can easily say that it was inspired by two very famous synths of
the early eighties, one is the Prophet 5 and the other one is the
PolySix. We tried to mix these two fantastic machines together and get the best out
of both. In fact, the oscillators in GVA-1 feature three waveforms each, triangle,
square and saw, with the ability to play them all at the same time; plus, OSC1 offers a
sub-oscillator and can be synchronized to OSC2. The VCF1 is a self-resonant 24
dB/Oct low-pass filter with overdrive in the feedback chain capable of screaming if
the resonance is cranked up, and it is preceded by a 12 dB/Oct multi-mode resonant
filter that resembles the gentle filtering of an early Obie. Some of the key points of
GVA-1 are: 1) pulse width is applied on all waveforms, not only square; 2) portamento
is applied in all modes including poly mode, not only in mono; 3) there are three
modes: mono (uses only 1 voice), poly (up to 24 voices) and unison (uses 8 out of 24
available voices); when in mono or unison mode it uses the last-priority criteria.
Another important feature of GVA-1 is the parameter "Analog Feel" that introduces
an adjustable oscillator and filter pitch drifting just like an analog synth, resulting in a
warmer sound and a pleasant intonation. The GVA-1 is perfect for any kind of analog
sound ranging from the fat brass sounds to the cutting sync leads to the warm pad
textures.
GSP-01 Sample Player
This is what we call "Adaptive Sample Player", it is a kind of "ROMpler"
that doesn't limit itself to playing back samples in a cold and static
manner. The GSP-01 can change its internal structure according to
the kind of sample-set that is loaded, adding or eliminating some of
its features accordingly. For example, there's a special "Physical
Modeling Piano Harp Resonance Simulator" that is only activated
when a piano sound is loaded and adds some surprising vitality to
sampled piano sounds. GSP-01 also adapts itself to various sound styles by activating
or deactivating the internal LFO, Pitch Bender, Expression pedal, or sustain re-
pedaling features. The total polyphony is automatically pre-calculated according to
the type of sound and is based on our Intelligent Note Stealing Algorithm. GSP-01
can only load custom GSi samplesets, and comes with a selection of multisamples
covering a wide range of sounds, some of which are sampled from our own vintage
synth collection. The sample library is expandable with future GSi releases that can
be easily imported into the Gemini.
