Hello Yves.

I have a friend who is having a problem (maybe?) with the saw animator I built for him. This is his message:

"Last night I plugged it up and it mostly seems to work fine. I do get a popping sound out of the 2nd channel when nothing is plugged in to it. With nothing going to the "In" of channel 1 and the 1 out going to the amp I don't get anything, but doing the same with channel 2 gives the popping. Once something is plugged into channel 2 the sound goes away and it sounds fine. Got any ideas on what it could be?"

Thank you,
-Elan

It's a perfectly normal behaviour, the saw animator needs to be fed with something (i.e a sawtooth) otherwise the output delivers the DC of the internal modulator. There is no point at listening at the output of this module if nothing is plugged in at the input Wink

Cheers

Thank you Yves! I thought that was the case.

Sorry to interrupt conversation, but can anyone post a samples of saw animator itself (normal operation mode) fed with something else than saw wave, any samples really? It seems like it does magic to single vco.

Feeding it with something else then a sawtooth is meaningless because all the effect is based on a saw. For example if you feed it with a triangle what you get is the equivalent of a mix between a triangle and a PWM pulse. Feeding it with a sqaure returns a square. Feeding it with some audio signal gives a distorted audio signal but if that's what you want you can get a better result with a disto box...

The reason i'm asking is because i've found this one
http://www.cyndustries.com/modules_sawtooth.cfm
I'm sure you are aware of this module, seems like it has pulse wave animation too (like many vco's doing pwms at different speeds), so i thought if your module could do that too?

But this type of feature is already available on PWM VCOs, feed the PWM with a random votage and you'll get the same effects.

I'm guessing that the Cyndustries module processes the output of the saw animator to produce a squared version. It uses the same input saw. You can do similar things with external waveshapers.

Is there an interconnection wiring diagram available for this add on board?

I'm not too great at reading schematics.

No, but I will try to draw one...

Much appreciated. Looking forward to getting this module working Smile

Assuming Yves is busy since there's been no further action in this thread for the past month, I wondered if anyone else has managed to get this working?

I have both boards assembled, but just awaiting an interwiring diagram. Does anyone else who has successfully interwired them have a few spare moments to put a basic wiring diagram together for me (and whoever else is stuck on this)?

It doesn't have to be anything flash, a simple hand drawn sketch would do the job.

Thanks in advance Wink

My pcb is still in the backlog, but this is how I would wire it up. Not tested so it might be some errors!

For the first part, the waveshaper, exchange the red cable going from LFO to Mod in the original wire diagram with,
Code:

                     ________________
                     |              |
LFO ---> Triangle_in*| add on board |*Sine out --> Mod in
                     |______________|


and for the output,

Code:

                                    ________________
                                    |              |
Dry Saw input       -->      Saw In*| add on board |*Output --> New Output
Original Saw Output --> Shifted Saw*|              |
                                    |______________|


"Dry saw input" is the same signal as you insert into the SAW pin, copper coloured.
"Original Saw Output" should the the purple output pin.
"New Output" is your output jack on the panel.

Do the same for both animators.

Yves mentions a switch on the output, that have not been added in this example. Havn't had the chance to try it out, so not sure if you need it.

Yes iopop3, your diagram is correct, nice ascii rendering by the way !

Can't really understand the ascii examples as there is only the add on board and not the main board showing, plus the labels you used don't match up with what's on the silk screen (I guess it's ok if you already know how it should be).

Although from what I can work out it would be like this..

No LektroiD, your diagram is not correct. I sketched one very quickly that shows the wiring for one channel only in order not to overload the sketch.
Here it is :

I wired up exactly as you suggested, but it doesn't work. I have attached an mp3 example of what I'm getting. It was working better without this add-on board, at least I had some kind of saw happening. The results are the same for both sides of the circuit (saw anim 1 and saw anim 2).

Basically I get clicks as the modulation cycles. you can hear the saw input as I switch it on and off. I also increase the rate up and down, once without the saw and second time, with.

Post a photo of the add on board track side and one photo of the components side such that I can check there is no mistake.

Just to be sure were you powering the addon board ? I did not show the power wire on the wiring diagram because it was obvious but one never knows...

I piggy-backed the power from the main board.

Please let me know if those photos are ok, or if anything is amiss.

I left the saw in 1 tip connected to the switch terminal of saw in 2, would that cause any problems? It's the only wiring that's not mentioned on the add-on board.

Incidentally, has anyone managed to get their add on boards working successfully, or am I the only one who can't get it working?

The wiring diagram is logically completed by mirror symetry.
I know at least three other people beside myself who built it without a problem.
I cannot see any obvious error on your PCB however you may check with a continuity tester that there is no shortcut between tracks or a microbreak in a track.
Check that the ICs on the board are correctly powered (+15V on pin 8 an -15V on pin 4). Have you checked the AOP ICs ?

i'm gonna build two Yusynth Saw Animator with all the bells & wistles Cool

- depth pot
- saw to sine converter
- mod output (why not having two more lfo's)
- mixer section (see below)

i'm refering to this thread and those two others :
mod output >
https://www.muffwiggler.com/forum/topic-21170-0.html&postdays=0&postorder=asc&highlight=&sid=a8006fd2316ed4ea68c4480bfb81f592

http://electro-music.com/forum/topic-49965.html


I have questions :

- i suppose the sine to saw converter can be made switchable
with a non shorting SPDT switch ?

- the original saw will be phase reversed at the output of the mixer ?
when layering, i would not want this.

i'd be more interested by a summing stage with Dry/Wet control
and phase flip switch for the phase shifted saw.

in the best case scenario with a VC crossfader
Do you think a circuit like this one could be integrated ?
either the manual or the VCA

thanks

just finished one half of the saw animator on the free parts of the stripboard from the Mutant BPF Version. Worked from start, but i was a bit curious how it would be if i can attentuate the Input Signal... so i placed a 100k attentuating pot with a 4k7 resistor in series from it's wiper and well it worked and gave some interesting results... fully cw normal behavoiur and with the Input level slowly reduced it gave some intersting sounding and looking figures until when nearly Zero Input only the Modulator Input remained at the Output...
