MOTM

hello all,

there was a little interest a while back when i mentioned midwest analog
modules, well i finally got the adv-midi up and running - even though it's
taken me around five months to build the bugger, it worked "straight out of
the box" - of course my custom panel needs a little work, but then they
always do

so you have a midi in, and eight trigger outputs along with some din sync
stuff like start, stop, and clock, eight flashing LEDs (heh heh), and it
works an absolute treat with my Korg ES-1 groove sampler - for some reason
my dark star doesn't seem to like it, but it's early days yet
if you interface midi to your motm, and you don't mind having to trash (or
keep in a box until hell freezes over) most of the kit then it's $60 or so
very well spent
unfortunately the url is at work - heh

anyway, i'm sure i deserve a beer now...
any questions..? (i'm sure this is suitably onlist)
oh yes, and i should get those other modules (bass & snare) working sometime
this week

cheers

"my dark star doesn't seem to like it"

What duration are the triggers? (Triggers are typically very short; the
DSC needs a *gate* signal.)

erm actually, if i remember correctly the term used in the adv-midi bumf is
"trigger" which would explain a lot, i'm kind of hoping i could use a lag
processor to stretch the trigger a little, or use my expertise to build a
little trigger to gate converter (conjure up images of infinite numbers of
chimps with typwriters here)
at least i soldered all the pins on the main ic this time...

cheers

A handy circuit for this is the CMOS 4528 or 4538 which has two one
shots on board. Add a resistor and cap and away you go. An example
circuit is in the MIDI-sync IC data sheet below.

hello,
i have the paperwork from the midiclock converter that i still haven't
dotten around to building yet
how could i alter the "gate length"..?

cheers
