Blue3 is an incredibly detailed simulation of the classic tonewheel organs that we all know and love. Those B-3's, C-3's and A100's are remarkably complex pieces of machinery with thousands of electrical and moving parts, which only partially explains their very rich warmth and tone. We've painstakingly simulated every single feature and circuit and more importantly, every single source of imperfection to give Blue3 its wonderful richness and complexity.

Key Features:

  • 91 modeled tonewheels with accurate phase synchronization.
  • Full polyphony for upper, lower and pedal manualsl.
  • Adjustable tonewheel leakage, crosstalk and flutter.
  • Selectable foldback for the 16' drawbar.
  • 9 contact key and busbar simulation.
  • Selectable keyboard split function.
  • Adjustable 3 band output EQ.
  • 30 tonewheel sets from vintage A100, B3, C3 & L100 instruments.
  • 6 way tonewheel scaling.
  • Adjustable drawbar output levels.
  • Hyper accurate vibrato/chorus scanner.
  • Completely adjustable percussion & vibrato scanner controls.
  • Classic 122/147 and "high power" custom rotary speaker simulations.
  • Guitar amp cabinet simulation.
  • Accurate manual taper & volume robbing.
  • Classic 40 watt rotary speaker tube overdrive simulation and high gain British guitar amp overdrive.
  • Completely adjustable rotary speeds, acceleration & deceleration.
  • Accurate microphone spread and distance controls.
  • Rotary horn diffusers on/off.
  • Front stop & Memphis control for rotary speaker.
  • Extensive MIDI controller mapping.
  • Includes Blue3Rotary, a separate plugin that combines Blue3's Tube Overdrive and Rotary Cabinet simulations.
  • 2 Stereo outputs, Main and Direct (pre-overdrive and cabinet).
  • Low memory/disk usage.
  • Low CPU usage.

Also very impressed with this Hammond emulation VSTi. Many many preset to choose from and infinite tweaks if you want to spend your time doing that. Very easy to integrate into my VST host (Cantabile 3). I used several different presets in last week's worship set list and was very impressed with how the keys mixed in with other instruments. Definitely not lost in the mix. Some of the brighter presets sound a little harsh to my ears but that can easily be adjusted by choosing a "waxed" tone wheel organ set versus a new one, or nudging in the top draw bars to reduce the high frequencies. I've used VB3 for years and more recently Acoustic Samples B5, but this will be my go to Hammond VSTi for the foreseeable future.

Hi Leeskeys, this is Leee1102. It seems like you have a pretty good idea of how to get the Blue3 to sound how you want it to.
I'm just getting started with it and as with many other users, I've been using GSi - VB3 and that has been my go-to Hammond B3 emulator for quite awhile.
I've been doing side-by-side comparisons, and it's been really a tough call to say definitely which sounds better. Some of the presets on Blue3 sound a little too harsh and synthy, but overall Blue3 sounds punchier than the VB3, especially when playing it in a song. One of the things I like better about the VB3 though is that it has a better "slide up" beefy sound. (That's when you run your hand over the keys starting at the bottom and going all the way up into a chord.) It's hard for me to get a lot of that deep bass sound with Blue3 when doing that "slide up", it doesn't seem to punch through, even after adjusting the tonewheel volumes and the EQ's.

Anyway, you gave a great tip when saying that choosing a "waxed" tone wheel organ set sounds warmer than the default set.
So I'd like to ask you what are some of your favorite presets in Blue3 and which is your favorite waxed tone wheel set?
My style of music and Hammond organ playing comes closest to the Santana/Woodstock sound. I've been experimenting with various presets but thought I'd ask if you have any suggestions for getting the best "Santana" sound (or similar bands). Thanks for any suggestions!
