Muff's Modules & More

[spbaker]

hi peeps,

i am trying to determine is my M10 Poly Env is working correctly, I have emailed PG about this and he assures me (via a long confusing email) that mine is working ok, but i just need to hear it from other owners. Here is the problem:

the primary envelope works fine but the "attack,attack" envelope seems to work fine until the end of its first cycle where it doesn't drop down to 0 again, it stays stuck on the highest level- now the thing that makes me more suspicious is the two gate/trigger outs the EOC & EOA both have the same issue, staying at highest voltage. They send out nothing (0 volts) when I first turn the module on, but as soon as I trigger it they all send out max voltage and continue to with out dropping back to 0. the EOC trigger output puts out a continuous voltage but momentarily stops when the envelope is triggered. i have been testing this with the CV ins on the Model 13 and when using the "attack, attack" env the gate of the M13 stays open continuously. I have also tested it with a few other modules (eg on filter cutoff/resonance, VCO CV in, etc) and the behaviour is the same.

Now the env diagram on the EAR/PlanB site looks like this:
but this is how mine seems to work:


and here is PG's explanation:

I can definitely confirm the ramp EG out (that's the "attack, attack" right?) behavior. Mine does that too, and was annoying at first, but I quickly got used to it. I'm almost positive the EOC / EOA gates work that way too. Another thing, about the EOC out, it does not do anything when the M10 is in LFO mode. That's the one thing that I really wish was different. I think it *does* work when cycle is engaged via the Cycle gate input.

I'm pretty sure the M10 mkII is no different in any of these aspects either, it simply has the ability to retrigger mid-phase. Personally, I really like that mine does not retrigger.

The EOA thing must be a mis-explanation on behalf of PG.

EOA output is ALWAYS high, *unless* the EG is in the attack phase. I guess there's a "mechanical" explanation why it's low when you power up the unit: It's the only time where you're NOT at the end of the attack phase - before it's triggered

The first graphic aren't helping a lot in that part though :-? but I don't see it as buggy behaviour, just a quirk, really.

Reg the ramp out... well that makes sense in my head, too - BUT his graphics show it dropping back down when it hits EOC, which is contradictory to what he's saying in your quote.

hey felix & wetterberg,

thanks guys! so everything is normal and yeah the original diagram doesn't make sense thats why i thought mine was faulty, phew!

i think if i had another envelope or a trigger/gate receiver then i would have been able to test further,

felix- tell me more about why you like the MK1 vs the MK2 with retrigger? I'm asking cause i know they sell a DIY kit to upgrade and i was contemplating it...

thanx thanx again!

I can check mine when I get home this afternoon, but I'm pretty sure the retrigger only works with the retrigger jack, not the main gate input jack. So you can choose to have it retrigger or not.

Need to double check though.
