trigger a filterbank with a ms-20

[novielo]

hi, well like tittle says i want to trigger the envelope of the filterbank 2 with the trig out of the ms-20. obviously it doesn't work, or it's inverted. when pressing a note the trigger light goes off, when releasing it, it goes on.

now the question: can i make a cable with inverted wire to make it work? tip to sleeve and sleeve to tip?

Does this help?

After reading it, I'm not entirely sure from the ms-20 which triggering method the ms-20 has.

[pflosi]

MS20 is s-trigger... it hits ground when triggering. the filterbank wants to see a v-trigger. thus it's inverted

try plugging the headphone out of the MS20 (or any other sound- or cv-source ) into the MS20 ESP, and the ENV out from the ESP to the Filterbank. Or - if you don't need envelope following from a sound source - even simpler, use the MS20 Output of EG1.

ok, thanks for the info.

but i i use the eg1 output i will have to set it on fast attack, so has the output of the head phone, which could cause a delay. while searching i came across this, i'm not sure where to put the 5v voltage in the first one: s-trig to v-trig schematic

[pflosi]

s- to v-trig conversion and vice versa is not a big deal. i've tried this schematic with good results:

(EDIT: just realized this is the other way round... in this case i never tried the other one... but should be easy...)

i don't really get what's your problem with the MS20 EG1 thing though???? what exactly are you trying to do???

[novielo]

i basicaly want to use the adsr of the filterbank to modulate the sample rate of a wmd geiger counter. but both envelope of the ms20 aren't set very fast.

MS-20 + FilterFactory !!
T'es pas un doux.

[pflosi]

so you need it faster? try the inverted out of eg2 with fast attack and fast decay

why not take the EG of the MS20 to modulate the geiger counter?

[novielo]

the inverted out does the same as the trig out, when no key are used it trigger the fb2 adsr, when you press one key the adsr is not triggered anymore.argh. it doesn't work with the trig out from the esp, it do the same thing, on when nothing and off when something is going on.

in this case if i use the eg from ms20 to modulate the geiger counter, i'll only be able to use the square wave and 1/2 of the saw, because the geiger can only receive positive voltage for its modulation.

i think it's in these kind of cases that you need a real modular

Ben quoi? y'a pas juste des pads dans vie..!!!

as i think about it... try the inverted EG2 with:

long attack (about 3-5)
fast decay (0)
no sustain (0)
no release (0)

it should act like a normal EG with fast decay now.

of course all the trigger outs dont work, also not in the ESP, because they are all s-trigger. i said to use the ENV out in the ESP, not the trig out...

still don't get exactly what you want to do... you want to be able to hit a key on the MS20 to send a trigger to the filterbank which ADSR cv would then control the geiger counter...? it should work very simple, with the EG 1 out on the MS I think...

bla bla bla

what i'm trying to do is:
-the ms20 doing a slow attack and slow release, using both EG
-and i want to put it thru the geiger counter, that will be modulated by and adsr, in this case i use the one in the filterbank, because it's the only one i have other then the ms20

while writing and searching on sherman website and manual for this post i came across the fact that the FB2 can do some kind of lfo with the link out plugged into the adsr trigger, with the adsr you can shape it to have more shape then a regular lfo. it doesn't synchronise with the trigger but it is less regular then a lfo. 1/2 of the reason i wanted a adsr at first.

[pflosi]

Ah now i get it. In this case you cannot use the EG2 on the MS, cause you already have that in use... do you make use of EG1? does it really not work to trigger the Filterbank with the EG1 output of the MS? Or if you only need a slow attack and release, you could use the EG1 straight away into the geiger counter, with the appropriate settings of course

[novielo]

i think i'm going to "cheat" this way, which ever evelope is faster ( the ms20 or for the geiger) will trigger the other one. i don't think i got much more options then that. it should still be fun
