Sorry this is a long one.

Hi Colin and all,

>You only need to use legato playing to control slide - the 303 always
plays
legato when it slides.

I was going to do this but how do you detect between legato playing and
using the pitch bend. I know the TB hasn't got pitch bend, but I use it
a lot. It is easy(ish) to fire a signal that detects CV change but no
gate, but it will not be able to tell whether that CV change is due to
keyboard CV or pitch bend. Most midi converters do not output a separate
CV for controllers. At least the cheap ones don't. So I planned on
having slide with or without legato, not quite TB, but easy to program
in grid edit, or on the MC.

>It doesn't sound like you are an insane 303 extremist,

I don't get extreme about anything anymore. :-)

>but I would recommend you copy the latch and r-2r network dac and slide
circuit from the original for driving the cv input.
I used the autoglide circuit on my cv convertor with my clone and
something
was missing. I suspect there is some 'dirt' at the start of notes on the
303
which doesn't happen with the cv convertor, that adds a bit of bite.

I think the slide is always on for the first few microseconds for each
new note. This gives it the bite, you are talking about. It may even
spike the CV as the 4066 changes state twice. I am therefore now
thinking about adding the narrow trigger pulse from the EG to modulate
the pitch CV, to introduce this. This worked well on my old Rogue when I
used it with my analogue sequencer... now, in bits, I needed the parts.

>A Cubase groove template with very small random shuffle may be just the
job
for simulating the 303 seq wonky timing.

Its gotta be worth a go.

Thanks for all the comments, keep 'em coming in,
