I've planned to do a MIDI to trigger board for ages, but got finally round
to it recently when someone I know needed one.
I'll get some PCBs made if there is interest.

The board is designed to be as generic as possible.
There are 8 trigger outputs, though a 16 output version would be a simple
addition.
Each output generates a trigger voltage between 0 and 14 volts, with a pulse
length programmable in increments of 0.1ms.
Each output can be assigned a MIDI channel and note number to respond to,
plus a minimum and maximum pulse voltage and length.
The actual value of output voltage and pulse length will then be scaled
between their minimum and maximum values based on the velocity value.
MIDI CC messages will allow the config values to be adjusted on the fly, to
allow the optimum settings for a given drum circuit to be found by
experimentation.
Sysex commands will then write permanent settings.
