# Tonewheel ### A Tonewheel Organ Emulation It's an almost accurate emulation of a Hammond Tonewheel organ, featuring 96+36 free-running wave-table sine oscillator, with original non equal-tempered frequencies. It'also has a tremolo unit, a tonewheel chorus, the classic percussion envelope, and an algorithmic [Schroeder Reverb](https://ccrma.stanford.edu/~jos/pasp/). I plan to add a saturation/distortion, and maybe a Leslie emulator. For now it's a standalone console project, without realtime parameters change during play. I've tested it under Win7 and Ubuntu 14.04/16.04. It's a little CPU hungry, I'plan to substitute the wheel chorus (emulating the Hammond BC or D Models) with a variable delay Tremolo, like the B3. It's based on [RtAudio](http://www.music.mcgill.ca/~gary/rtaudio/) v4.1.1 & [RtMidi](http://music.mcgill.ca/~gary/rtmidi/) v2.1.0. You need to download them and compile these packages as static libraries for your platform, to use the makefile and the codeblocks project without changes. Only the headers are included in this repo. You'll need an external MIDI keyboard or some controller emulator to run it. Under Windows I strongly recommend to compile RtAudio with **ASIO** support ( you will need the ASIO SDK from Steinberg, it's free but cannot be redistributed. To obtain it you need to [register as a developer](http://www.steinberg.net/en/company/developers.html) at Steinberg) . Then you will need an *ASIO Driver* : [ASIO4ALL](http://www.asio4all.com/) is the standard for non-pro audio cards.
