Yeah, it’s strange. Maybe they are reworking it… or found some bugs. Can’t say…

On the other hand, here is the alternate version i was referring to :

I’ve been using the Individual Wavebank firmware and quite like it. Having different random modulation sources available on 4 different outs is really handy.

Are there any small, AC coupled attenuators (not mixers) out there? Preferably in 2hp or 1u. I’m looking for one to help remove DC offset from FM patches but can’t find anything that isn’t DC coupled. I guess I could get a 2hp MMF and use its highpass for this, but a straight attenuator would be more useful overall to me.

EDIT: thanks for moving this to the correct thread!

Shakmat’s 2HP HiPass doesn’t have attenuators but it does have four fixed HP filters.

That one would be less useful for my particular case than the MMF, since I really wouldn’t have a use for the 3 other filters. I always handle that sort of filtering in the box when recording if needed.

I guess I could go with Pulp Logic’s 2180 VCA. I just wish it didn’t need an external offset to open it.

I have PP and Brains and Rene V1 along with an SQ-1 for my “official” sequencers which I couple with a bunch of different utilities to make more complex sequences - Doepfer a-185-2 precision adder, a-151, RYO Paths (I just added this one), uO_C running Hemispheres, various vcas etc. PP + Brains with a sequential switch shouldn’t be underrated - you can do a lot using the various inputs to brains and clocking the sequential switch in different ways.

One fun trick with the sq-1 (or similar) is to take your simple 16 step sequence into a vca and then modulate the amplitude of the VCA with another sequencer running at a fraction of the tempo (1/16th or 1/32nd) and then plug that into your quantizer. Or use pressure points as your second sequencer and do it manually. There’s a lot that can be done with simple sequencers if you have the right utilities.

I think having a midi to cv module for linear sequencing is the right idea. My Octatrack is a pretty powerful sequencer after all.

I’m often using the Erica Pico for exactly that purpose.
Yes, technically a mixer and 3HP, but for that price …

Does an AC coupled input remove DC? I don’t think it’s designed to pass DC alone, but if it’s mixed into an AC signal it will pass a DC offset along with the AC, won’t it?

#1674

AC coupled will remove DC offset, though DC coupled allows both. AC coupled typically means a capacitor on the input to block DC.

I’ve seen plenty of DC offsets recorded into digital samples (where you see the whole Waveform offset one way or the other against the zero line) made on a wide range of equipment, and none of them purportedly DC coupled. Is that supposed to be impossible with a capacitor on the input of the A to D device? Maybe these samples were made on defective equipment? That’s entirely possible.

#1676

Yes, me too. I assume most output modules will filter this too?

Does anyone here have experience with the Hexinverter Midi2cv? I picked one up on reverb recently and it worked perfectly for one jam, the next time I fired up my synth it had the startup lights but isn’t responding to any midi. Anything I can do shy of sending it back? I hate putting sellers in that position, but so far nothing I’ve tried seems to wake it up.

Hi!

I’m currently entering the world of eurorack, madness I know, the only way I learn something is if I go and build it myself, i’m building a little VCO based on a teensy 3.2 (I have a github if anyone is super keen to see it but it’s basically based on a tutorial).

I’ve Converted the -5V to +5V voltage range of the CV in to a nice teensy 3.2 friendly 0-3.3V. The next step is to implement 1V/Oct, but then it got me wondering, are all CV in voltages standardised to a frequency? So if I feed 1V into gear A, does it produce the same frequency as if I feed 1V into gear B? I had a search but couldn’t seem to find a definitive answer, obviously if it does then I will need to code it up accordingly.

No. Anything that produces a pitch has a tuning knob on it. (Sometimes if the manufacturer is nice they have two course & fine)

So you set what the voltage “means”

Also beware different manufacturers have different ideas about control voltages. You’ll see 0-10v or -5 to 5v etc

Just adding to this -

Sending in 1V to the V/8 input will double the frequency of any oscillator, but the original frequency (and thus the doubled frequency) will depend on the position of the tuning knob.

#1681

Ahh OK, I think the thing that was throwing me was that the pitch controls on the beatstep pro show notes corresponding to a CV out so I was assuming it was standardised.

#1682

I believe that C normally translates as a whole volt, so C1 is 1v, C3 is 3v etc. At least that’s how my MIDI to CV converter works. That would translate as F# being at .5v, as it sits half way between C octaves.

hello,

this is my first time posting after lurking for some weeks, so i hope this is the right place to post. happy to have found this forum.

I’m asking for help as I am the 2nd owner of a MN Maths (V2) which has developed some problems after some years of quite heavy use. The decay pots for both envelope channels have become scratchy and the resultant decay times jump all over the place occasionally when the pots are turned rendering them almost unusable, the CV inputs are fine. Example here

Is there anything anyone can suggest as to get rid of the issue?

#1684

Your video link unfortunately doesn’t work, but if you’ve already tried some deoxit on the pots to no avail, I’d shoot Make Noise support an email. They’ve always been quite helpful in my experience.

#1685

thanks for the quick response, video should be visible now sorry about that.

And yes i’ve tried contact cleaner & emailed support - awaiting response but I think they may be unwilling to help seeming as I’m not the original owner.
