VB3 The Ultimate Virtual Tonewheel Organ



System Requirements
Minimum System Requirements:
Microsoft Windows 98se/ME/2000/XP
Intel Pentium 3 @ 500 MHz or AMD Athlon @ 500 MHz
256 Mb of RAM
10 Mb of free disk space
An ASIO compatible sound card
A 61 keys MIDI keyboard
Recommended System Requirements:
Microsoft Windows XP
Intel Pentium 4 Dual Core @ 3000 MHz or AMD Athlon @ 3000 MHz
1 Gb of RAM
10 Mb of free disk space
An ASIO compatible sound card with near-zero latency
Two 61 keys MIDI keyboards and an expression pedal
VB3 is a VST plug-in, and needs a VST host application to run. We recommend EnergyXT or Hermann Seib's VSThost / SAVIhost. And if you want to experience the feeling of playing "the real thing", you should have at least two 61 keys MIDI keyboards, better with "waterfall" keys, stacked one on top of the other, an expression pedal and at least a drawbar controller. Or if you have a digital dual manual organ console you can map all of its physical controllers to VB3's controls using third party applications like MIDI-OX and/or Bome's MIDI Translator in conjunction with the Maple Virtual MIDI cable for interconnection between the applications.

Basic Concepts
VB3 is a virtual tonewheel organ which simulates an american electromagnetic organ of the old days, but it's also capable of other simulations like the italian transistor organs of the seventies or the red-tolex organs played by famous pop bands of the sixties.

Main features:
Full polyphony (183 notes)
Virtual 91 modeled tonewheels generator with accurate phase synchronization
Adjustable leakage noise and cross modulation between tonewheels
Three sets of waveforms: Set H (American Electromagnetic), Set F (Italian Transistor), Set V (Red Tolex Transistor)
Motor wow & flutter
Busbars and 9 key contacts simulation
17 steps drawbars
Two separate sets of drawbars per manual
String Bass with adjustable release time
Dynamic pickup coil impedance loss
Adjustable generator filters scaling
Single triggered percussion with natural capacitor discharge/recharge
Vibrato/Chorus virtual scanner
Dynamic tube preamplifier simulation
Tube overdrive simulation
Spring reverb
Smooth action volume pedal
Stereo wooden rotary speaker simulation with artificial environment and microphones positioning
Rotors brake position
Adjustable background hum and noise
Very low CPU consumption
Midi controllable, supports VST automation
How it works
Yes, it's not a typo. The first feature in the list says it's 183 notes polyphonic. The original organ, mostly one of the most famous models, had two 61 keyboards (also known as "manuals") and a 25 notes pedalboard, for a total polyphony of 147 notes. Digitally speaking, it doesn't make sense to use a separate routine for scanning the pedalboard, so VB3 uses the same routine for the keyboards and treats the pedalboard as having 61 keys. 61 multiplied 3 = 183 notes. Of course, the more notes you play at once, the more CPU power is required. But, for a normal playing situation you won't use more than 12-15 notes simultaneously, and if you lay your both arms on the keyboards and both your feet on the pedals you won't reach more than 100 notes, and your computer still may have more than 50% of free CPU power, depending on the system specs it has. So, how does it work? It's very simple.
