glide using the sequencer (and some other seq/mod-matrix issues)

glide using the sequencer (and some other seq/mod-matrix issues)

2003-02-10 by Miles Bader

I tried to get osc glide to working using the Evolver's built-in
sequencer, and couldn't manage to get anything to work.

My thought was that perhaps the Evolver's `glide' function is legato
only, and the sequencers short gate-time always defeats it (or
alternatively I suppose it's possible that the glide is implemented in a
way that gets bypassed by sequencer inputs).

The gate-time thing is a also kind of annoying, at the least, it'd be
nice to have a patch-specific sequencer gate-time parameter (I guess
this has to be a percentage of note length?), or even better gate-time
as a mod-matrix desination.

For instance, if you want a sequence that goes blip-blip-boooouuuuuum
(esp. where the boooouuuuuum lasts across several steps!), how can you
do it?  Given no gate-time control, at first I thought, `ah I'll just
use a sequencer channel to modulate envelope release or at least
sustain' -- but in fact only attack-time is a mod-matrix desination!

Other similar ideas proved fruitless, and in the end I found a sort of
ugly and limited solution, by using ENV3 to modulate the VCA, and then
using the sequencer to modulate the amplitude of ENV3.  This seems bad
because it seems to waste an envelope, and only allows you to have a
single `alternative decay,' instead of being to have step-specific
decays if you could modulate the normal VCA envelope's release or decay
time directly.

Any thoughts?  Has anyone found a better way to do this?  Should I send
yet-another feature-request email to Dave Smith?  [I read that Dave
Smith is reluctant to do lots of OS upgrades, so maybe it's pointless
anyway, but it's certainly easier to think up new features than
implement them!]

BTW, has anyone come up with other useful mod-matrix destinations that
aren't implemented?  Maybe there should be a list of `desired
destinations' ...  From above:

  gate-time
  env release/decay/sustain

and maybe:

  osc glide (1/2/3/4/all)

Thanks,

-Miles
