edit VOICE
Siemens SAB80C535 with physical-modeling DSP core generates 12 voices polyphony at 20 bit resolution.

virus A technical info

VIRUS A: the synthesis is a mix of virtual analog modeling and short PCM waveforms - these are the Harmonic Waveshapes.

editSTRUCTURE
A VIRUS voice is composed by 2 oscillators + 1 sub-oscillator + 1 noise source.

PERFORMANCE system handles 16 multitimbric parts with individual settings:

- velocity assign to FM, pan, shape and width
- variable portamento time
- 4 mono playmodes
- 2 voices stack (with detune)
- Midi channel assign
- key zone assign
- note transpose
- pitch detune
- assign analog out / volume
- note priority
- FX amount

filterFILTER 2 filters (-12 dB each) can be combined in 2 serial, 1 parallel or directly set to independent mode. Both filters feature 4 different models:

virus filter

- lowpass
- highpass
- bandpass
- bandstop
In addition a special Keyfollower option plus a filter saturation which basically emulates a vacuum tube distortion.

adsr ENVELOPE 2 EGs:

EG - EG1 AMP: 4 segments + 1 time
- EG2 filter: 4 segments + 1 time with possible EG inversion.

 




lfo LFO
up to 3 delayed modulators:

EG mode: yes yes no
Symmetry: yes yes no
Destinations: pitch / width / resonance / filter gain osc shape/ Fm amount / cutoff / pan pitch /width

MATRIX like a modular, the Virus handles 3 internal routings or virtual patchcords that connect a modulation source to a destination:

fx EFFECTS
there are 2 digital FX onboard:
- delay: with rate, time, modulation LFO and feedback.
- chorus: with rate, depth, delay, feedback and LFO shape demo HEAR chorus



 

midi ARPEGGIATOR simple function with latch and 4 directions: up / down / up-downd / as played. Virus arpeggiator and LFO1-LFO2 can be sync internally from 63 to 190 BPM (there are 17 time dividers) or slaved to external Midi clockdemoHEAR arpeggiator

TIP: there are 2 freely assignable knobs to any Midi CC#.

my model always had trouble with random values, finally found out a non-soldered resistance (from factory?) probably I had bad luck, now it is perfect (check out pic).
