Need help - SH101 circuitbemders (off topic)

Post by isak »

Hi guys :)

i'v done the circuitbemders mod for my sh101.
after i finished my SH101 went crazy :cry:
http://www.circuitbenders.co.uk/Circuit ... 1guide.pdf
i didnt do the novamod cause it was a bit complicated without the pics like in circuitbemders :oops:

the problems are..
it doesn't sound like FM at all..
when the all the SH101 VCO slide pots all the way down i still hear sounds cause of the FM amount pot is up, as i switch the pot switch the sound changes to what it should be (sqr, saw, sub snd so..).
i dont think it suppose to play any sound when the FM amount pot is up..?

Image

this is what i did...(i put the spst switch off, i wanted only the amount to be the on or off)

Image

did i'v done this mode correctly?

i think its the non so quality pots :?
when i play with the wires that connected to the pots the sound is gone and back gone and back, like there is a connection and no connection..
i tried lin pot and it was ok, but for this mod i need a log pot and i dont have them now :(
every log pot i'v got here is bad :x
i will order some Alphas or if any one here have some spares Alphas 100k log pots i'll be happy to buy them from you!

Hi guest.

i replaced all pots now its ok, but still i dont get the FM sound i was looking for.
it seams that the FM amount pot acts as a filter pot and not as an amount.
the pot center pin connected to this junction..
Image

when the FM amount pot is all the down i get no sound at all, only when its up i get sound but not pure sew or pure sqr its dirty, not dirty as in ground problem or bleeds ...dirty as in sort of effect..and not FM ..
when i heard the effect at circuit-benders i wend crazy and the effect does not sound even close.
u can check it here : (roll dont a bit, their is 4 sound samples, please listen to the first one from the left till the end, this is FM!)
