Eric,
 
very nice work, and useful too.
 
Not being that up on electronics, any chance of a schematic?
 
Or maybe you fancy making a few and selling them? 
 
Regards

	Subject: [Doepfer_a100] Manual Trigger/Thru DIY project
	
	
	Hi all
	
	Just wanted to let you know that I just finished one of my do it
yourself
	modules for the A-100
	this one is a 'Manual Trigger / Thru' module
	
	This module has 6 sections, of which 4 are a manual trigger/thru
(top
	section) and 2 are a manual trigger only (bottom section)
	
	** Manual Trigger/thru
	has a INput, a manual momentary pushbutton and an OUTput
	if nothing is connected to the input, the output gives a +5V
trigger each
	time the manual button is pushed (and as long as it is pushed,
so it can
	operate as a gate as well)
	if there is something connected to the input, the output gets
the throughput
	of this each time (and as long as) the manual button is pushed
	
	** Manual Trigger
	this only has the push button and the OUTput, as soon as you
press the
	button the output gives a +5V trigger
	
	usually you connect another trigger/gate/clock source to the
INput of the
	Manual trigger/thru, to enable this to be throughput with the
button
	
	what do I do with this module?
	well, it is not a revolutionary design or high risk DIY project,
but for me
	it is quite an invaluable tool
	because I can produce (max) 6 triggers manually, with which I
can start
	Envelopes, start/stop or clock the sequencer, switch a VC-Switch
or
	Sequential Clock, trigger a next sample/hold, reset an LFO,
switch from one
	sequencer to another (by means of a VCS or Seq switch) etc etc
	this means that I can start, change or stop all kind of sound
effects and
	patterns with only a couple of pushes on buttons, and I don't
need any
	keyboard (which I would like to keep for the usual playing)
	
	at this moment it can only be mounted in a rack with the +5V
power source
	(such as the basic system with midi) I do take the +5V from the
bus directly
	but I will expand the module with a simple circuit to create a
+5V source
	from the standard +12 V power
	
	at the yahoo A100 site, I have put a couple of pictures of this
module, in
	the Photo Albums section in the album called Manual Trig/Thru
	you can identify the Manual Trig/Thru sections (IN-red
pushbutton-OUT) and
	the Manual Trig sections (black pushbutton-OUT) easily
	
	if you want to know more about this project, please don't
hesitate to ask
	more projects are in preparation
	
	Eric
