Delivering old-school acid bass lines, the Xhun Audio ZeroBox, is an accurate analog modeling simulation of the legendary Roland TB-303, the iconic sequencer-driven bass-line synthesizer that defined an era. This software virtual instrument plug-in utilizes physical modeling with Advanced Component Simulation (ACS) to preserve the original architecture featuring all of the micro-instabilities and imperfections of the original instrument.

Additionally, several improvements and circuit-bends have been added, bringing the synthesis engine a step ahead. The redesigned sequencer front-end includes a full set of modulation, analog saturation, and multiple types of distortion. The 130+ factory presets cover a wide range of genres, well suited for any electronic music scenario. The software works on Mac and Windows systems, and operates in VST2, VST3, and AU formats.

• Physical modeling simulation of real analog hardware, achieved by the adoption of the Advanced Component Simulation (ACS) approach—oscillators, filters, envelopes, and more are built preserving their original architecture, featuring all the micro-instabilities and imperfections of the analog technology
• Full 64-bit processing accuracy for every single aspect of the simulation
• An all-in-one complete setup: monophonic analog bass-line synthesizer + embedded analog sequencer + analog and digital insert/master effects

• An aliasing-free analog modeled oscillator proving the same capacitor charging/discharging responses as found in the original analog circuits, featuring sawtooth and square waveforms with blending (morphing) control
• A separate control for the oscillator waveshaping (from naive to analog supersaw / pulse width modulation)
• A legendary 4-pole resonant, analog low-pass diode ladder filter (modeled by the adoption of the topology-preserving transform / zero-delay feedback approach) proving all the original quirks, nonlinearities, frequency responses (also at extreme modulation scenarios), analog clipping
• Two analog envelope generators (MEG/VEG) proving the same capacitor charging/discharging responses as found on the original analog circuits
• Analog component age selector. Choose the virtual age of the components used in ZeroBox, and as a consequence, its resulting overall instability
• An extended operative range (compared to the original) for several knobs and internal components
• Built-in circuit-bends as found in different hardware clones and experimental ones never seen before (while 100% preserving all the original functions)
• An exclusive low-frequency-oscillator (LFO) with frequency (from 0.05 Hz up to 20 Hz) and destination amount controls, affecting the oscillator waveform blending, waveshaping and filter cutoff frequency
• Adjustable high-pass filter cutoff frequency
• Adjustable filter envelope (MEG) minimum decay time
• Adjustable slide time control
• A VCA envelope (VEG) smoother control
• Polarity inverter control, useful to achieve different sound flavors when using an asymmetric (biased) distortion unit

Three ways of control for studio and/or live scenarios:

• Sequencer Off: Individual notes are MIDI triggered directly by the DAW
• Sequencer (Pitched): The internal sequencer (8 scenes/patterns per preset) is MIDI triggered and tuned
• Sequencer (KeyTrig): Each of the 8 sequencer scenes / patterns per preset are assigned to different MIDI keys

A multimode (PTC/KTG) embedded digitally controlled clock generator and sequencer, featuring the same internal pulse timing and behavior of the original one, with:

• Mode selector (normal/triplet)
• Beat pulse-divider selector
• Tempo external controls
• Swing amount control
• Step gate control
• Step pitch control
• Step octave selector
• Step slide control
• Step accent control
• Steps number (from 1 up to 16) selector

Including an insert effect slot with the possibility to choose:

• CHOR-S unit (rack): Expressive stereo chorus effect
• FLANG-R unit (rack): Expressive stereo flanger effect
• X-TREME unit (rack): Accurately modeled, ground-shaking tube distortion effect
• SOLIDA unit (rack): Accurately modeled transistor distortion effect
• PHEEBEE unit (rack): Expressive digital foldback distortion effect
• CRUSH-R unit (rack): Creative digital bitcrusher effect

Including a master effect slot with the possibility to choose:

• D-LAY unit (rack): Tempo-synced stereo delay effect
• REEVERB unit (rack): Resonator-based electronic reverb effect

• Multiscene loader engine with 8 scenes per preset
• Including 130+ ready-to-use factory presets collection covering multigenre styles
• Multicolor synth panel (silver grey or acid yellow)
• MIDI automation
• Support for sample rates from 44.1 to 192 kHz
• Available in multisize GUI resolutions

Q: 3. Can U3C be used even with a dynamic microphone that doesn't need phantom power with phantom power switched off?

A: The Xvive Audio U3C Set Wireless Plug-On System for Condenser Microphones is only meant for condenser microphones, and the manufacturer specifically advises against connecting dynamic microphones to this system. It does not appear that phantom power can be switched off on this version and therefore has the potential to damage dynamic microphones.

Q: 4. Is the internal battery replacable?

A: The internal batteries in the Xvive U3C system are replaceable but the will need to be replaced by the manufacturer or an authorized service center.

Q: 5. Can U3C be used with condenser microphone for capturing bird songs with Nikon Z8 mirrorless camera?

A: Yes, the XVive U3C Set Wireless Plug-On System for Condenser Microphones will be compatible with condenser microphones, however it will need some sort of adapter in order to be fully compatible with the Z8. You will need to use an adapter like B&H # KOLMT100.

Q: 6. Will this work with a gopro hero 5 black?

Q: 8. Can the Decimator 2 simultaneously downconvert the input to composite while passing through the original format to HDMI?I want to input 720p59 over HD-SDI and output both 720p59 over HDMI and downconverted NTSC composite (anamorphic).

A: From what I have read, yes it can, however I will double check and get back to you. However, I am using 1080p/60 so there may be a difference for you. But this thing is fantastic

Q: 9. I need to convert PAL signal to NTSC signal so I can send it into my video switcher then out to my projector. I am using this in the US, but my client is sending me a Broadcast in PAL. for the audience to view. can this unit do this?

A: Yes, the Decimator 2 3G/HD/SD-SDI to HDMI Converter with Built-In NTSC/PAL Downscaler will be able to convert SDI in PAL to NTSC in a composite down scaled format.

Q: 10. Can you charge the transmitter/receiver while it is in operation?

A: Thank you for your question. You are unable to charge the receiver or transmitter while it is in use. They do last an average of 5 hours on a full charge to get through most performance situations.
