Ciao Fons,

you're right in your perfectionistic view - this isn't a software simulation
of the real Continental. Thank you for the dissection of the signal flow - the
lack of cheap hardware like opamps led to some creative solutions with their
own special sound.
My first goal wasn't to simulate a specific type of one electronic organ but to
develop a common toolbox to build an instrument with midi in and jack out. At
the moment the sound range is from very soft (8' stop only and flute -> sine
wave) to very harsh (all stops and reed). I'll experiment with triangles and
square and some kind of "real electronic" waveforms.
The actual version improves i.e. reduces the key click (especially at key
release). I dont switch the sound on/off at key press/release but ramp it
up/down for some milliseconds - that's not what a real organ does but it
sounds better. :)
The vibrato is also a playground - it's a simple mixed fm and am that
simulates one leslie horn (without crossover) rotating in free field without
early echoes etc. The "vibrato" drawbar controls the rotating speed (the fm
modulation strength and the speed of am pan shifting).
I implemented this effect into the organ because it's easier to do the fm at
the sound source.

The "gui" is now a bit easier to handle - I switched the keyboard to
noncanonical and unbuffered.
