Subject: RE: [motm] More UEG tweaks!


One more issue I've been working on is the switch bounce. I have found an
implementation that doens't penalize the response to the leading edge of a
trigger, BUT it does limit the repetition rate of the GATE.
For example, if I use 5mS dead time on the rising and falling edge of the
switch, the input GATE is limited to just under 100Hz. This isn't a problem
when it comes to using the UEG as an envelope generator. It takes over 60mS
just to complete all the stages so most likely your input gate repetition
would be slower than 60mS. If you try to input a faster gate, you simple
start to chop off the final stages. The issue is with GATED-STEP mode
(sequencer). Without any debouce code, I can take the UEG up to about 450Hz
input, and it runs fine all day.

So I need more feedback: Would you like a little debounce is exchange for
some gate speed, or screw the debounce switch stuff (since you hardly use
the switch) and keep the speed?
