Another innovation
from Paul Maddox is his
MIDI to SDS Trigger converter.
This re-released version of the MIDI-2-SDS
has the same features as his Version 2 model:-
- converts MIDI signals into SDS
triggers, you can use it to fire other drum machines
- the unit has 8 trigger outputs,
each of which is velocity sensitive
- control of the 'gate' time is
via an onboard preset (~1mS to ~132mS),
- it has a 'learn' mode, which
lets you assign different notes to different triggers
- it has 8 LEDs, so you can see
which channel is being triggered and which channel you are
'teaching'.
The new pcb release
includes the following minor changes:-
- simple filter on AVcc supply
to improve noise immunity of the analog circuitry
- onboard-connector option for
MIDI-IN
- onboard-switch option for LEARN
- diode protection for 78L05
regulator
- additional input filtering
on power supply
- option of a 16MHz crystal or
a 16MHz Oscillator module
- option of dual power rail with
extended trigger output voltage range
