CGS07 - Gate Sequencer Reset
2017-06-24 by Paul Bower
Hello there,
Just wondering if anyone could recommend a way of modding the reset input to accept +5V instead of +12/13V
Cheers

I should work that way already. Perhaps increase the size of the 10n reset cap to 47n to let a bigger pulse through.

Re: CGS07 - Gate Sequencer Reset
2017-06-25 by Paul Bower
Good to hear from you Ken - hope things are good over there
Since that’s all I had, I just put a 47nF cap across the existing 10nF and that did the trick
In case anyone else comes across this, it was a very old board. I could get the gate sequencer to reset from its own 12V step outputs, but not from an LFO that was sending a 0-8.5V squarewave (and certainly not from a variety of things I tried at around the 5V mark)
So all fixed - I can reset on a 4.5V pulse now
I assume that if I get misfiring problems now then I just need to reduce the value of that bridging cap a little ?
Cheers
Paul

The only "issue" having the reset cap to big is that it may prevent a clock pulse from advancing close to when the reset occurred.

Re: CGS07 - Gate Sequencer Reset

You mean a kind of lag between the reset event and the clock advancing to step 2 / step 3 etc ?
I’ll check for that - I just tacked the extra cap on the back of the board, so it’s not so much of a faff to try some lower values

It would miss an entire step if it was a problem.

Re: CGS07 - Gate Sequencer Reset
2017-10-01 by Paul Bower
Hello there,
I’m fairly certain this was all working fine, but yesterday I realised that the Step Out on Step 5 wasn’t working. It may have been like that for some time because strangely the LED was working just fine, just no output at the jack. I checked everything on the main board, replaced the BC547, then realised that the LED wouldn’t light either under certain switch conditions for that step and the previous step - which I’m certain I would have noticed. After an afternoon of power off/try something/power on cycles, the problem has spread to Step Two - so I’m wondering if the 4017 might be on it’s way out
Got to order a 4017, and I hate desoldering, so I’m wondering if you’ve any thoughts ?
BTW I tried cutting loose my extra capacitor, per the reset fix below, but that didn’t make any difference
Cheers
Paul

Re: CGS07 - Gate Sequencer Reset

You have a bad jack or have miss-wired it, or perhaps you have broken the pad where the wire is soldered from the PCB. I can't think of anything else that would cause this problem.

Re: CGS07 - Gate Sequencer Reset
2017-10-02 by Paul Bower
Just want to check something on the switchboard - I have a board that has only six wire links marked on the silkscreen - the inner six links between the rows of switches
I realise on the current documentation that there are a further six wire links on the edges of the board. My PCBs don’t have Rev numbers, but am I right to assume these are earlier boards that don’t require me to figure out the extra six links ?
Just to re-iterate, apart from the column output weirdness (partially fixed by poor connection on an LED) that Gate Sequencer has been working fine for a number of months
Cheers
Paul

Later boards only needed 6 links because I found a way to eliminate the outer links.

Re: CGS07 - Gate Sequencer Reset
2017-10-03 by Paul Bower
Success
I was trying to figure out how the hell the column LED would light but the jack wouldn’t output the pulse, then (after fixing a couple of dry joints that broke from repeated dismantling) I realised that if the output was shorting to the chassis, but the ground cable wasn’t… …then… …maybe… …i got the wires backward… …Yup the pulse output wires for that stage were backwards, but the LED wires were correct
Can’t believe it took me that long to figure out - I’m definitely blaming the chemo on this one
Thanks for your help & patience as always Ken
Hope things are good over there

Super Psycho Modulator
2017-12-29 by pigeonsmusik
Hi,
I need some help in getting the SPM to work.
I've soldered up all the components and pots and the links and even added a link at the 0v above the 100uf caps.
When I power up the unit, the leds don't blink and unless I touch one side of the cable linking to the led, on the end of the led, the led lights up but it doesn't blink.
I'm using yellow leds for the individual oscillator. And I've connect a orange led to the LED driver section and LD driver to the output of the banana jack that i'm using.
I'm using MOTM power distribution board from CGS and only +15v, 0v, 0v, -15v is connected.
I can't figure out where i went wrong. Any ideas or help would be greatly appreciated!
Thanks
best
Dennis

Re: Super Psycho Modulator

No doubt a construction error, but your description does not give enough info. Try posting or emailing me a photo. You do not need a link between the 0V holes above the 100uF caps - that is a point where you can access 0V in case you need to wire something to it. The link will not hurt anything though.

Hi Ken,
thanks for your speedy reply.
here is the pic… of the board and the wiring…
yes i was aware of not needing a cable for the 0v part but since it doesn't work, i thought it might be some grounding issues.

Oh no!!! Yes ur right…. I didn't understood what RL stood for…. now i see the problem after referring to the schematics and the tracks on the board!
thanks for pointing that out and thanks for the help. Will hook it up… hopefully (fingers crossed) that it will work!

You have left out all of your LED resistors RLED. You need to chose the
value of those to suit the LEDs you are using.

Re: Super Psycho Modulator
2017-12-29 by pigeonsmusik
connected up the 1k resistors to RL … I'm using yellow leds rated at 20mA, 2.3 volts for the oscillators. Tried both 640k and 1k resistors at the first led.. but still doesn't light up. when i touch the anode side of it though, it lights up.. but i get a buzz in my fingers.
I'm using an orange led at the led driver, that lights up with my 1k resistor. So i guess the 1k should be alright with the yellow leds, since they have the same rating.
When i connect up the output which is a banana jack to my passive banana to 1/4 output, the led on orange shuts off. There is no audio out from the output. I left the gnd connection next to the output on the pcb empty. I also exchanged the ics.
checking again…

LA is connected to the anode (+) of the led and LC to the cathode(-) of the led. seems right. My SPDT switch is connected OF to top, CO to middle and LF to bottom of the switch. that seems right too.
do i have to connect the GND next to the OUT to the ground since I'm using banana sockets?

And I've connect a orange led to the LED driver section and LD driver to the output of the banana jack that i'm using.I'm using MOTM power distribution board from CGS and only +15v, 0v, 0v, -15v is connected.I can't figure out where i went wrong. Any ideas or help would be greatly appreciated!ThanksbestDennis--Modular Synth PCBs for sale <http://www.cgs.synth.net/>
