I was just reading a review of the Future Retro XS, and it mentioned  
it had something called an 'Accent Envelope'. This is apparently a  
separate envelope that can be configured to take over from the default  
envelope with MIDI velocities over a threshold value. Is this an idea  
we can steal for the Hawk-800 maybe? I guess you'd be able to specify  
an Accent Env. for the filter, for example, and the threshold velocity  
value at which it would replace the standard filter env.

Just a thought..

Sounds like a great way to emulate the TB-303 accent.  I won't go into
the long and frankly terribly boring explanation of how it works.
Suffice it to say that if you too are the sort of person who can be
bothered to clone the TB-303 envelope circuitry just to measure its
behaviour so you can write a software emulation, you might want to know
the gory details.

The 303 accent is more complex than you think.

I know that. I'm not looking for a completely authentic 303  
emulation- I know you'd never get that from a Poly/EX-800. But  
several people on the list have mentioned wanting various envelope  
parameters to respond to MIDI velocity, so this might be a nice  
simple, and flexible, way of achieving that.
