If you don’t mind footswitches:

monome Walk (if you can find one)
Doepfer A-177-2 (2 gates and an expression pedal option for the second channel)

Doepfer also had a 6 HP Manual Gate source, the A-164-1. The odd thing about it was that it would output 12 volts.

I looked into manual gates quite a bit at one point to use with my ER-301. The ADDAC manual gates module is really nice too and can act as a gate for audio as well on some of the channels, but that is even more HP than you specified. Another nifty gate option is the intellijel Planar - it has a gate button. A big module, I evenutally sold it.

Something to keep in mind about Ears is that it’s a piezo and can act unpredictably in certain louder situations.

I wound up getting the newer Ladik module with toggle switches and momentary buttons that invert the connection. I’ll patch a voltage to it when I need regular gate generation.

What I really wanted was something with selectable latch/momentary behavior, like Antimatter Launch Codes, but smaller and cheaper (since I don’t need the gate recorder).

Which Ladik module is that?

#755

I really like Ears but as noted above its pickup is quite sensitive. It often reacts from other interaction within the case, like when a cable is unpatched or a button is pressed. But this can be solved by mounting it in a better suited place in the case or by some sensible dialing. Still a must-have in my book.
This is a little something I did the first day I got it, but nowadays I normally plug my guitar or some other instrument to it.

Could you hook up a piezo sensor to an enclosure of some sort (e.g Hammond 1590A), and then mount a jack output to that?

That way you would have a handy little ‘piezo stomp box’ for hitting/stamping/scraping etc.

It would also be isolated from noises in the case.

#757

I guess so. I’ve not experimented that much with this module yet but I’ve mounted a homemade piezo contact mic to different things (cymbals, aucustic guitars and so on) and it acts like you describe. But since my contact mics are quite worthless the noises comes from a lot of different places instead.

Seen this?

#758

I should add that this is for a live/improv case, so some unpredictability from Ears would be quite useful in some situations :slight_smile:

P-075. I was thinking it was newer but it’s from May 2017.

Hi all.

I’m trying to grasp the concept of ‘offset’ and how to really use it. Specifically I’m trying to work out how to control CV in the same way I am able to control the Max for Live LFO that comes with Live using the ‘depth’ and ‘offset’ controls it has (for anyone familiar with that). They are so simple to use, and with them I can pinpoint so precisely the position, range and depth of the LFO’s modulation.

I’ve been trying to figure it out with Maths but I can’t seem to fully understand how to do it, or really how the ‘offset’ on there works. If anyone has any quick (or slow) advice as to how or what might influence a CV signal in a similar fashion to using the depth and offset controls on that Live LFO, I’d be grateful.

(Edited for spelling)

To offset a signal with Maths you’ll need to use a channel, say Ch. 2, to attenuate it, then Ch. 3 to offset it, and take your signal from the SUM output. With this signal path, Ch. 2 will be your “depth” and Ch. 3 will be your offset. Is this what you’re talking about?
Edit because I’m an idiot.
LFO -> Maths Ch. 2 (attenuation/depth)
Maths Ch. 3 will control your offset
Maths SUM out -> LFO destination

don’t patch channel 2 into channel 3! that would just give you more attenuation

channel 1 and channel 4 have attenuverters you can use for their respective envelopes/lfo.
Example:
If you use channel 1 as an lfo, use channel 1 attenuverter to attenuate.
Keep channel 3 and 4 attenuverters to neutral.
Use channel 2 to offset the signal.
Sum output will be resulting CV you want.

#765

Thank you very much! I’ll try this. But/and would this not then also work with an external LFO (or other modulation source) patched into channel 2, using that attenuverter to attenuate, and patching on to channel 3 using that to offset (as @edbkt is proposing if I got it right)? But if you say this wouldn’t work @alanza, how is then using channel 1 (and Maths own LFO) onto channel 2 (as @electret is proposing) different from what @edbkt is proposing?

Am away from system at the moment but will trial and error as soon as I can. Thank you all three!

#766

My bad, forgot how to Maths for a minute.

patch the external signal into channel 2, use channel 2 knob to attenuate.
use channel 3 to offset.
Sum output is result.

Thanks a lot! (This is the same now as @edbkt is saying in their edited post, as far as I can see.)

#769

Yes, sorry for being cryptically brief. in general with modular synthesis, you have to include some form of mixer whenever you could just include a “+” object in Max for Live.

Note that for a lot of modules there are typically two ways a knob responds when the corresponding CV input is patched: the most common is to act as an offset, but sometimes it will act as an attenuator or attenuverter instead

Not familiar w the Live device but essentially channel 2 of maths is providing attenuation (decreasing depth) then, when using the SUM output, the unpatched channel 3 amount (which is just a static dc voltage) is added or subtracted to/from the LFO providing your offset. Basically what this is is an attenuated lfo and a static dc voltage (say, 1 volt) both being added up in a DC coupled mixer with your final output being lfo with offset. Maths is great but can make simple things seem confusing at first :wink:

#771

Thanks a lot @alanza and @addamm.

I still don’t completely understand how one channel of Maths knows to offset rather than attenuate. They’re both attenuverters, but one functions as an offset. How does that happen?

I really need to dive deeper into the depths of how CV modulation works. It’s confusing to me because oscillators and low frequency oscillators and how they work together with envelopes and VCAs and even sequencers seems to me fairly clear and straightforward (even though I might be deluding myself), but when it comes to fine nudging or sculpting of CV, my head becomes porous. I have a hard time really understanding what a module like Blinds does for example (I understand the words in the description, but I don’t understand what the result of using those functions are, in practice).

What you are helping me understand how to do with 2 channels of Maths here, do you have examples of how you would achieve the same result with other modules? Maybe this also helps to make it clearer.

And thanks so much again. Hopefully I am not the only one pondering these things!
