sMs SN Voice Build Subject description: built and done - ? Mixer select A - C |
|
|
edit: i've looked a little deeper and see it will do it, i just need to figure out how to switch it between on/off on pin 25/26/27
i've finished my first sMs board SN voice Build, MOTM style. the default setup for the output is Either Noise or Pulse. I was somewhat expecting this Voice would mix the pulse and the noise? the documentation shows a 10k output pot , which is not on the MOTM panel, i paneled mine to emulate the MOTM panel available.
i'm wondering what the referenced Mixer select A , and Mixer select C are for? my switch(S2) is J2-6 , which outputs to J3-1 ,
does either of these mixer sel options mix noise and pulse? or what do they do?
thanks,

i have finished my pcb (finally after 8 years of owning the board...)
However i am struggeling with the frontpanel, i have a MOTM system (which seems to be rare these days) and i found https://modularsynthesis.com/mrmrshoes/sn-voice/sn-voice.htm
It was the only motm fpd i could find. Yet it looks great and the mixer looks like a very nice addition. However i have no clue how to do the wiring from the sMs board to this panel.
I did find the extra mods. But i am stuck with the switches for mixer selection. How to attach them to j3-1 j3-11 and j3-12 or is this not possible with the sms pcb?
Thanks in advance. |

It is possible to connect things the way you want to, but the signal on J3-1 is not the MIXER "B" select bit you want. J2-6 is actually MIXER "B". It is the PULSE/NOISE select bit on the SMS SN Voice boards. J3-1 is a different signal called PUL/NOISE which is actually the main analog audio output being either pulse or noise on this design. The is signal is the OUT on your MOTM panel becasue NOW it can be a combination of SLF, VCO, NOISE and gated combinations thereof using the MIXER control bits. To summarize:
MIXER "A" is J3-11
MIXER "B" is J2-06
MIXER "C" is J3-12 |
