DTG and TGO

DTG and TGO

2009-08-05 by roelelec

Hi all,

Last evening I had a big breakthrough with the SSG.
I thought I had read and studied all the tips and tricks on Egres, but I had forgotten about SSG Hijinx part 1-3 from John P., probably cause it's almost tucked away under the group module listing. I didn't read it before, before I actually had the Serge that is, cause I wouldn't understand it anyway, so I thought back then. I had forgotten about this section. The clear writing of John P's way to patch-program the SSG, did the trick for me. Thanks John!

I succesfully patched from the smooth section a staircase generator, a triangle lfo, a square lfo and a non-linear filter.
I also tried to patch the linear glide, but that didn't work out, cause I didn't manage to get a proper trigger for this purpose.

I tried to patch a EG from a TGO and DTG before, but no luck. It must
be quite simple, but I don't seem to get it right. So my question is how to patch a ASR and AR out of TGO and DTG?
I used the gate and also the signal in, but still couldn't get it.

Something else, related to this. I'm low on cv source. I don't have a TKB, don't have a sequencer, so momentarily rely on any EG I patch from a DTG and/ or TGO. My question is: Do I need the extended ADSR's or are the enveloppes I can patch from a DSG (this M-panel will be next on order) sufficient enough? I mean to make automatic melodies and such rhythms without a sequencer? Last evening I also combined the smooth and stepped section with the cupl and I was amazed about the jumping melody I got!

Thanks for help in advance.

Cheers,

Roel

Hey Roel -
nice to have another european on the list !

re your ?s bout the DTG as an envelope generator -
It works very well as an AR
stick a trigger into the "trig in"
the "gate" is an output - it outputs a gate level when the AR event is
finished
If you want an ASR connect a gate ( or any other positive voltage that
you want the DTG to track ) to the "signal in"

You should go to James "carbon111" Maier's webpage and download the
copy of "The Gold Book"
that he hosts - the section on how to get envelopes from a DSG applies
to the DTG

all the best, - Kim in Copenhagen

You don't need a trigger to use the Smooth section of SSG for glide.
Just patch any old thing In, and use the Smooth Out to drive something
else, like an oscillator.

Yes, you can use the SSG Stepped for sample-and-hold fun, if that 's
what you're looking to do. Trigger it with the Smooth square LFO
(autoerotic sample & hold). Patch a repeating lfo from a DTG or other
module into Stepped In, and use Stepped Out to drive an oscillator. Make
sure its Rate is fully clockwise, at least to start with.

Happy Patching!

Hi Kim,

So, your from Copenhagen, Denmark, I'm from Maastricht, the Netherlands.
Hot weather over here now. No less then 30 degrees celsius today!

Oh, I read all the stuff you mentioned. I have read the Gold book 4x times already and visit Maiers webpage very often. His tread on the DSG "alphabet soup", although I don't have them yet, was very exciting and promising. My problem is, that I'm more a musician then a technician. Most of the guys here have one or more degrees in science. I don't, I lack technical insight. Have to delve deep into the stuff to know f.e. what a non-linear filter is and does. Till recently I never heard of this term. Now I know. For me it has been a steep road, but an exciting one and I'm learning.
I like to know what I'm doing. F.e. want to know when I use a patch-programmable module, what module I created when I connect f.e. a gate and a trigger in. Being familiar with the east cost philosophy, this kind of multifunktionality was completely knew to me. And I may have made this connection earlier, but didn't recognise, what it was, I created!
You say stick a trigger into the trig. in, but I have learned that you have different kind of triggers and enveloppes in the Serge and not all are sufficient in each situation. Is a pulse from the random source the right guy? With other words, Do you need a random trigger to create a AR?
Since I have no TKB and no sequencer, a enveloppe will react in a different way, then when you trigger it via keys or a sequencer. And probably also different when I connect a EG to a oscillator on my Doepfer A100.
That's something I thought. In some cases the 4 outputs of the DTG are not audio, but subaudio. I find out that when you don't touch the rise and fall knobs the right blue out is a subaudio triangle wave, which can be used for modulation. As soon as you tweak those knobs, your entering audio territory and get, depending on the position saw or inverse saw. The red one below is subaudio pulse, when tweaking knobs you get pwm. Which is cool, but took me some time to figure this out.
I gonna try it, the way you mentioned. I think, it must work the same way for the TGO, since it also has a gate and signal in.

What I want to know is, if these AR and ASR's are sufficient enough for rhythmic melodies or that I still need the extended ADSR's. I hope not, since I don't want the other modules in this M-panel. My next batch will be the Dual or Quad slope (I'm I crazy or what! I don't see any difference and yet the quad is 50 dollar higher in price! But both have 2 DSG's!!)

Hope to hear from you again.

Cheers,

Roel

Re: DTG and TGO

Hi John,

Thanks for the tips!
I will try them.

O, I tried the CUPL out for the first time. But I accidently did it in a odd way. Logically both halves, smooth and stepped come together in the CUPL output. But I was a hazy in the head, so I patched the out of the smooth into the CUPL out! Now on any other system did would have let to nothing, but not on the Serge, I got some wonderfull complex and jumpy melodies!!


Can you also help me with the following dilemma.
Is it worthwhile to buy the ASR quantizer panel when you don't have the TKB and or a sequencer? I like to do melodic and melodic rhythms, regular as irregular.

For the next batch I definately go for the Dual or Quad Slope. My opinion: no respectfull Serge system should be without one! And probably the CV processor, since my system is already strong on the audio processing side thanks to the wave processor.
For the last M-boat there will be a big fight, who will be in and who don't. I already made a list of losers, but still too many M-panels want to get in!

Cheers and thanks,

Roel

Roel,

You might benefit greatly from having an oscilloscope around. Maybe you could borrow one from one of those science guys and have them show you how to use it. This would let you see the signals and that could help you gain some intuition for what's going on. A picture's worth a thousand words.

Re: DTG and TGO

That's the nail on the head, Steve!
I would like to have oscilloscope, to see how f.e. the waveform changes it's shape or to read the voltage when it goes down hill, in the negative so to speak.

These things as you know are very expensive and I don't know anyone in my
surrounding who has such an apparatus. Meaby I should try secondhand.

Thanks anyway.

Cheers,

Roel

i just plug something into the "trig in" on my DTG and DSG and if it
triggers a cycle - its a trigger :)
any voltage with a sharp rising edge should do it - i also have an
envelope detector and an NCOM on my panels and both can
turn an audio signal into a signal useful for triggering..

I always thought of the controls on the DTG in reverse of what you
describe here
- with the "normal" position of the knobs fully
clock-wise -
we all have our own personal approach to the Serge i guess.

My first panel was a custom one very similar to the animal shop panel
- with a DTG as the only eg source
That was my only panel for the next 6 years.

The DTG and DSG are fine for envelope duty - the ADSR is nice when you
use voltage control of the individual stages
but apart from that theres not that much of a difference IMO

Hi Kim,

To create a trigger on the DTG is easy, you just connect the gate and trig. and presto, it's starts to oscillate. The first time i tried to get some action out of the DTG, was a bit of a puzzle. I put a patchcord in one of the outs, patch it to a cv in on an osc. and expected the light to go on. Nothing. Even when I turned the rise and/or fall. The light stayed dead. No sound. Until I patched the gate and trig. in, after a few seconds the light came on.
I read that a full wave rectifier can be a good envelope detector. The bottom of my Wave multiplier has a 3 full wave rectifiers. May those can do the trick. I don't have an +Ncom yet. But I certainly want, at least one in my system.
So a inverted saw on my TGO could do as a trigger!

Why do you have the knobs fully clockwise when you start? That means
you start at the high frequenties. Of course there's no law who states you must
start from the left. I start with the knobs fully left, so there in the lowest frequenties when I tweak the knob. The graph above the knob points this out. The tickest is analog to the bass range and the thinnest is where the high frequenties reign.

Do you use a keyboard for the Serge, a tkb or another non-Serge?
It just that the response, when I have patched an AR or ASR, is so odd, so different then I'm used to that I wonder what I do with it!
I tried several triggers to trigger in, reaction can be as radical as that it immediately shuts of the DTG and I need to pull the patchcord out and in again, to make it come to live again. I noticed the same phenonomon on the TGO.
I definitely buy the dual DSG. My system can't be without them!
