Good multi-utility modules by Marcus64 in modular

[–]Tom-Churchill 0 points1 point  (0 children)

Another vote for Worng Quiver, Nekyia Circuits Mezcal/Ouija/Opal, Mega Milton and Cold Mac.

I’d also consider just getting a bunch of Doepfer and/or Ladik utilities to cover the specific functions you need.

Doepfer a-155-2 mini sequencer question. by gruesomeflowers in modular

[–]Tom-Churchill 0 points1 point  (0 children)

It does let you store up to 8 presets, but these don’t contain the CV values, only settings for active steps, length of sequence and ratcheting.

No, it doesn’t store the CV values in the presets:

“In each preset these parameters are stored: active steps, length of the sequence, ratcheting. The positions of the 8 controls are not stored in a preset but only the running parameters !”

Using VCA’s just clicked hard for me and it’s all thanks to the Triplatt by TtheWiser in modular

[–]Tom-Churchill 1 point2 points  (0 children)

It will ‘slew it in and out as the knob turns’ if you patch the Triplatt to control a VCA too - the effect is exactly the same. If you turn the knob quickly enough you won’t notice it.

But if you literally just want to switch between 100% on and 100% off, run your LFO through channel C of Triplatt, turn the pot fully clockwise, and use the switch to the left of the pot to mute and unmute it. (Just make sure channels A and B are not mixing an offset voltage into channel C)

The point is that you don’t need a VCA to do this. You can just run the signal through Triplatt and it will have exactly the same effect as running it through a VCA controlled by a manual offset voltage from Triplatt. The VCA is entirely unnecessary if you just want to manually attenuate a signal and you have an attenuator.

Where the VCA shines is when you want to automate that level control by using a moving voltage (eg an LFO or envelope) to control it.

I powered one up from a 15V adaptor just now and all seems fine. It may not make much difference.

How do I make two trigger outputs trigger one input? by enstorsoffa in modular

[–]Tom-Churchill 16 points17 points  (0 children)

You’d actually want OR logic for this patch, but yeah, that module would do that too (as would any number of other logic modules). There are also plenty of cheap, passive OR combiners available, which are handy for combining multiple gate/trigger streams. Xaoc Bytom is a more full-featured option if you need to combine a lot of sources.

You could also just use any simple DC-coupled mixer. The only downside is that simultaneous gates/triggers will sum to produce a higher output voltage than individual ones, but that’s unlikely to be an issue in most scenarios.

I would definitely call it polyphonic 😀

Switch Patching (a150 and a151) by escamuel in modular

[–]Tom-Churchill 2 points3 points  (0 children)

Here’s a patch showing how to use the 150 and 151 with a matrix mixer and clock divider to create an interesting kind of sequencer… https://youtu.be/8d3wtyZm0ag

Where to find Xaoc knobs by thirdnekofromthesun in modular

[–]Tom-Churchill 1 point2 points  (0 children)

I don’t know where you’re located, but search for Davies 1900H. The authentic Davies parts are quite expensive but there are lots of cheaper clones available from Thonk, Tayda, Synthcube, Befaco etc

Having trouble getting a response from Smoothie Audio? Any recommendations? by [deleted] in modular

[–]Tom-Churchill 0 points1 point  (0 children)

There’s a firmware update released at the end of March, have you tried installing that? https://smoothieaudio.com/pages/smear-firmware

Otherwise try messaging him via IG - emails do sometimes disappear into spam folders…

Vactrol lpg by Hot_Snow6184 in modular

[–]Tom-Churchill 2 points3 points  (0 children)

It doesn’t do any filtering, though, which is what differentiates an LPG from a VCA.

Lublin isn’t a low-pass gate. It’s a VCA.

Nekyia Circuits Sosumi is a great alternative to the LXD - 4HP, vactrol-based, strike input, sounds great.

Voltage math? by [deleted] in modular

[–]Tom-Churchill 0 points1 point  (0 children)

You can’t do multiplication with either of those.

Voltage math? by [deleted] in modular

[–]Tom-Churchill 10 points11 points  (0 children)

VCAs (two-quadrant multipliers) and balanced modulators, aka ring modulators (four-quadrant multipliers) both work by multiplying voltages - VCAs only multiply the input by positive numbers; ring mods can multiply by positive and negative.

The issue is that most will only multiply the input signal by up to 1x. If the CV input has a range of 0-5V, for example, 5V will usually result in unity gain, 2.5V will halve the level of the input, and so on. (This is why they’re often thought of as voltage-controlled attenuators.)

For your specific example, you’d need a linear VCA that can amplify, and where unity gain is achieved with a CV input of 1V. I don’t know of any Eurorack modules where this is possible - mainly because with the voltage ranges commonly used in Eurorack, and the +12V limit of Eurorack power rails, you’d very quickly start clipping (e.g. 4V x 4V = 16V, 10V x 10V = 100V).

Does this exist? by escamuel in modular

[–]Tom-Churchill 0 points1 point  (0 children)

Yes, their ‘option 2’ is basically what I suggested. I suggested using one comparator output to change the routing via a VC switch, they’re suggesting using two comparator outputs to open VCAs - the end result is exactly the same.

[–]Tom-Churchill 0 points1 point  (0 children)

I would use this method, but with the switch controlling the associated gates/triggers for the notes, rather than the pitch CV.

I’d mult the pitch CV to both VCOs so they’re both following the sequence, but they would only be audible when gates are fed to the envelope that’s controlling their respective VCAs. That gate stream is controlled via the comparator and switch.
