get a bigger Panel
Or squeeze your layout down. within 5 mins of power up you will wish you hadnt left out X.
But I should shut up, cuz I still have 2 SNs to build! |

have you looked at fonik's euro version: http://www.modular.fonik.de/Page23.html ? elegant as usual, i've lifted a couple of his euro designs straight to frac.

Dan, have you tried using a drafting program like QCad for knocking up some front panel designs? QCad doesn't cost much, and it's a lot easier to use than FPD. Failing that there is Cenon (I don't know what computer you use, but Cenon only works on Linux and Mac OS).
It could help you design your panels. _________________ ACHTUNG!

The thing with QCad, Dan, is that it is a proper CAD drafting program (it looks very much like autocad btw, but is much easier to use). As it is a proper drafting program, when you specify a 10mm radius circle, the final dxf file will have a circle with a radius of 10mm (as long as you keep the scale at 1:1 of course!) _________________ ACHTUNG!

I was able to fit all onto a frac format panel. I'll try to remember and take a picture when I get home tonight.

SN VOICE questions..how to fit on panel! |
|
|
Concentric pots are a great space saver (look at the Oberheim SEM), but they're expensive and can be difficult to find in the right values. Also, the knobs tend to be more expensive too.

photon-id love to see that picture....looks like for now i am using a 2 wide and a 1 wide together to make a 3 wide panel to fit everything on...
pots-
i dont get how to use concentric pots for the sn...when you turn the knob it turns both pots right? so how can i apply that? i cant think of any parameters on the sn voice that would fit that...that id want to have turned at the same value all the time....
i did use them in a filter i built this summer though _________________ -------------------------------------------- check out various dan music at: http://www.myspace.com/lossnyc

concentric pots don't have to turn at the same time. I remember them well on a Soundcraft mixer I used in the 80s when I was doing sound for bands a lot. The mixer had an arrangement where the outer ring was the frequency for the EQ and the inner was the amplitude. It worked very well. _________________ Garret: It's so retro.

On older car radios, the outer ring would be tone or balance while the inner would be volume. Independantly adjustable, knid of like one stacked on top of the other. |

Heres the panel. crap photo (sorry my camera is a toy), but I think you get the idea. The pcb isn't wired to the panel yet bec. I haven't figured out how to wire the on-on-on switches to work as 3-way selectors (paging Mr. Herrmann...) as seen on Foniks' SNV.
hope this gives you some ideas.

I have to say that I disagree.
I think the SN-Voice features are a bit exhaustive. The module is designed to be a complete synthesizer voice. More then many of us need as we already have working systems, monosynths, samplers etc...
I am not saying that having a complete voice is a bad thing...
But sometimes you need to look at the space and time with reference to the BANG.
The best thing about the SN-Voice is the Noise source imho. It is very unique sounding., and combined with Thomas' cool CV circuit it is very useful... to me.
I also feel that TH left out many things that interest me abot the SN chip. SO I added those things (all mixing and triggering logic is wired to the fron panel for VC or manual control). This is where the oscillator shines. As a AM source for the triggering section, or mixed with the noise using that screwy logic controlled mixing section.
WHen I build another SN-Voice (I have 4 boards left). I will probably not utilize all the features. I could do without Linear FM, AC-DC coupling, Triangle Out... perhaps just a single CV input with attenuator for both the OSC. and the Noisen (one each).

Thanks Fonik.
It wasn't the German that was confusing. I didn't understand your diagram.

Has anyone figured out how to use a 7211 switch to select VCO or Noise or a mix of both. I have been trying and trying but so far i have VCO or Noise or LFO |

I don't think you need to waste a 7211 switch on this.
The logic for selection of noise/VCO/both is as follows:
Code: |
SN76477 Pins
Output 25 26 27
Noise 1 0 0
Pulse 0 0 0
mixed 1 1 0
|
You only need a 3 position switch (on-off-on) to get the three required logic levels at the SN chip.
Check the following diagrams for switch wiring and simple logic gate circuit required to perform the translation. Points A and B correspond to each other on both diagrams.
When the switch is up, A is Low, B is High. This translates to pin 25 being high, and pins 26 & 276 being low so noise is selected.
When the switch is in the centre, Both A & B are high. This translates to pins 25, 26 and 27 being low so Pulse is selected.
When the switch is down, A is High and B is Low. This translates to pins 25 & 26 being high and pin 27 being low so both noise and pulse are selected.
Looking at it in truth table form:
Code: |
Switch SN76477
2 2 2
A B 5 6 7
+-----------------
U | 0 1 => 1 0 0
C | 1 1 => 0 0 0
D | 1 0 => 1 1 0
|
Which means:
Pin 25 = A NAND B
Pin 26 = ! B
Pin 27 = A NOR B
