Y Cable is going from CV AB to Gate (red mono cable) and to Pitch (black)
Same cable (four of them, just in case ) as before.
CV A is V/Oct and CV B is Gate… sorry for my lack of understandind of tips and sleeves. Thats how i undestand it: Red and Black :). Just actually following steps…
I got good knowledge of synths in general, but modular stuff and older gear is way out of my leage.
Well, if you’re getting a gate then you’re probably set up right. I don’t think a 1v/oct would have high enough voltage to trig a gate unless you played on the high octaves.
Maybe it’s just a bad cable?
The difficulty with a Y-splitter is that you won’t know which side is ring or tip
I have a minitaur and slim phatty set up perfect (I think). Will post my settings when I get home. I’m pretty new to all of this so it took me a while to wrap my head around.
on another note. in checking my settings i noticed my gate had been bumped to 10v. i hope there is no potential for damage in this. I played for many hours the other day
If you look at the bus boards in a eurorack power supply you’ll see that they send +/- 12 volts to the modules. Euro modules are built to support these specifications and presumably this is good for all V/octave gear
A hot signal from a CV output can often be in and around 10 volts if you check with a multimeter or oscope
As for other gear. Don’t think you’re in any real danger with damage from high voltage. Always worth checking the specs just to be sure.
I do know that audio interface i/o need to be DC coupled in order to safely accommodate CV and gate signals
Can anyone with a slim phatty confirm those settings? As far as i can tell its mapped perfect but on paper those numbers dont look right for 1v per octave…
don’t know if it will help, but, Slim Phatty (Minitaur too i think) are .98v/oct so won’t track very well unless the CV can be attenuated to this. Can this be done inside the A4? I’d be very interested to know.
buy yourself a cheap tuner.i have korg ga-1. or you can use an app on your phone, also there many free software tuners…
when you set the CV outputs correctly, go to PitchV/Oct settings.
there you will see the “first note” and “last note”…
lets say you set the first note to c3 (three octaves from the first and the last should be okay),
then you press YES on A4 and the modular should trigger that note…
if your tuner says its out of tune, tune the voltages until you get it correctly.
then you go to the “last note” and do the same.
it should be tuned that way.
someone with more expirience should help even more
That is correct. I just got done tuning mine today (using a free phone app), and it’s as you describe. As a crude visual, you’re basically “expanding and contracting” the voltage limits of the two notes until they lock into an octave that matches the tuning you’re after. For example, my Slim Phatty is tuned accurately with the following settings:
Note 1: C3
Voltage 1: -0.413V
Note 2: C6
Voltage 2: 3.103V
From what I’ve seen, these settings will vary from one Slim Phatty to another (or any synth, I guess). I went online assuming I could just pull up someone else’s settings and be good to go. Turns out, I tried every setting I could find regarding the LP/SP with the A4 and none of them worked for me, or even came very close. This was my first foray into CV so I was pretty frustrated.
I ending up pretty much tweaking everything until the octave range I settled on sounded close to what the A4 puts out, when playing both machines from a MIDI keyboard. Then, using a tuner, I pushed and pulled the two voltage values until each was hitting “C”, one octave apart. Once you get the two notes pretty close to a “C”, the finishing touches come fast. I could do the whole thing again in a heartbeat, but cranking the knobs around the first time to get in the ballpark took a couple minutes.
I imagine my settings won’t apply in your case, but hopefully the above description helps break it down for you a little better. I see your post is already a couple weeks old so maybe you’ve got it sorted by now. In that case, maybe it will help someone else down the road.
if you can explain what’s not working, you’ll most likely also explain what you’re doing wrong !
.
set a channel up to be value line
set the output to be 0min and 0max
plug it in, set Value lin dial to max on main page
note the pitch or play another synth droning along at this pitch
now vary max voltage until it’s one oct higher
note the voltage
vary it until it’s 2 octaves higher, note value of max v
same again for 3 oct higher
.
now, if the first value is not the same as the gap between 2 and 1 & 3 and 2 then there’s a problem with linearity
.
now you know roughly what the v/oct should be set to
it may not be a volt, like the example above yours illustrates
now you know if you approximately set
low at C3 and high at C6
what kind of v difference you should be entering
this is usually very easy for other gear as it’s normally 1v / oct
.
then adjust the position of the range to suit the range of the gear vs a4
.
if that doesn’t give you an understanding, I’m not sure how to help
.
the instructions given in the OS supplemental notes should be followed (this may now be in latest manual, but may not be - this explains in detail what to do)
.
I’m just trying to help you uncover where the issues are, you’re report that the problem is with the tuning is not helpful at all
.
details ??
what’s wrong
) as before.
