Un émulateur de Yamaha YC20, un orgue de la fin des années 60, par Sampo Savolainen.
Un émulateur d'YC-20, un orgue de la fin des années 60.
L'émulateur reproduit fidèlement les caractéristiques, sons et défauts de l'orgue d'origine, il utilise le serveur Jack et le protocole MIDI.
Foo-YC20 is a Yamaha YC20 emulator. It's written in Faust and uses jack for audio and midi and Gtkmm for the UI.
The emulator is mainly developed on Linux but can be built for OS X or even Windows. No releases for a specific platform are yet planned though.
The YC-20 is a divide-down combo organ designed in the late 60's. This emulation faithfully copies the features, sounds and flaws of the original organ.
This is a Faust implementation of a 1969 designed Yamaha combo organ, the YC-20. In addition to the Faust code, it has a Gtkmm UI with Jack audio and midi support. A LV2 instrument plugin is planned but not yet executed.
Original YC-20 organs have a touch vibrato control, which is vibrato induced by horizontal movement of the keys. As there very few (almost none) midi keyboards which produce such information, this feature has been left out of the emulation. Instead of the touch vibrato control, the control panel hosts a "realism" switch.
The realism switch has four positions like the drawbars. Each position adds a "feature" to the previous position. Thus all three features are enabled at the last position. The positions are:
off: unrealistic mode
2/4: oscillator detune
3/4: percussion manual bleed
4/4: drawbar bleed
Also, unlike the real YC-20, this synthesizer provides additional separate outputs for the bass section and selected main voice. The volume of these outputs is controlled with the same controls as the main mixed output.
The balance and brightness controls are in fact continuous controllers even though the ui shows them as having four positions like the other switches.
The MIDI implementation does not care about midi channels. As Jack MIDI offers flexible routing, there is little need to filter messages based on midi channel.
☑ Physical modelling, no polyphony restrictions
☑ 61 keys
☑ Two main voice sections
☑ Switchable bass section
☑ A realism control to add flaws found in the real organ
