CV controlled switch modules you love

Author CV controlled switch modules you love

While building my system I've stayed away from sequential switches and other routing modules as they seem 'boring' compared to uber-cool oscillators/FX/filters, but now realising the benefits more.

I was looking at a simple Doepfer switched multiple, but then thought I'll probably appreciate being able to switch between two sequences with a trigger pulse. There's loads of capable modules on the market and tricky to know which are best without demo-ing, do people have specific modules they love for this job? Cheers! smile

I love the Klavis Mixwitch. It does swtiching and a lot more (check the manual), feels well made and is priced very kindly. My best value buy yet, I think.

For a basic but versatile 1 I/O to 4 O/I sequential switch the Doepfer is hard to beat:
https://www.modulargrid.net/e/doepfer-a-151

The ADDAC214 is a 4 I to 4 O sequential switch so even more powerful for scrambling things up and also adds CV control over position:

The STG Switch is a 4 I to 4 O switch that has some great features too. I just took delivery of the 5U version but I haven't tried it yet. It looks like the eurorack version has the same feature set.

And if you have the room don't write off the Doepfer A-182-1 you were considering and get both. cool Some times a manual switch is all you need. (I modified mine )

I was planning on picking up an Erica Sequential Switch V2. I've quite liked Erica's stuff so far and that module seemed like a good value for the money and size.

That Mixwitch looks interesting! Not what I had in mind for a switch, but I can see the usefulness. Nice design, too. Sharp.

I love digitally addressed things.

Take a look at the NLC Statues for example: it’s a 3 bit addressed switch/ T&H. It has 3 digital inputs that map to a 1-8 address space, selecting one active channel out of 8.

Another good one from NLC is the Numberwang. This one has four binary inputs that map to a 1-16 address space. Combine this with a VCAM and you have a powerful 4x4 multiplexer.

If you are already running trigger sequencers to drive your rhythms, they can also be used to route modulation and audio around. All you need is a stack of VCAs and trigger sources. The VCAs will pass through signals when a gate is high and mute them otherwise.

What the modules I mentioned do is open a single route and close all the others but nothing is preventing you from routing one source to multiple outputs simultaneously, or multiple sources to a single output, or multiple sources to multiple outputs all at once.

To bridge the gap between analog an digital I use a Drezno, so I can use an LFO or a S&H or any analog modulation source.

I have an Erica Pico SEQS.
CV controlled Sequential Switch.
It sits right next to my Pressure points.
It even color matches them.
Works a treat.
And no, I didn't mistakenly buy it thinking it was the Pico sequencer. d'oh!

+1 on the erica v2, it is an amazing switch. crazy versatile for the space and $$. switching cv is great, but i use it almost exclusively for switched audio ie switching through verbos HO sines, or individual qu-bit chord outputs for harmonically related crazy blippy madness.

(btw, full disclosure, i am selling mine if anyone is interested, only because i am transitioning to an all doepfer system, other wise i'd have two hihi )
mdoudoroff
If you’re doing a medium-sized or larger system, I think the WMD Sequential Switch Matrix is one of those must-haves.

The Mixswitch—mentioned above—is pretty neat, too. Great value in a multi-function device.

Speaking of multi-function devices, don’t overlook the new Befaco Muxslicer, which DivKid just did a video on. Clever and cheap.

Softwire Synthesis - Octal Voltage Controlled Switch has both manual and gate controlled switches.

Stages also makes a great sequential switch.

ALMs Boss Bow Tie is worth considering too:

https://www.modulargrid.net/e/alm-busy-circuits-alm007-boss-bow-tie

It's CV addressed rather than sequential which may or may not be what you're after.

can anyone attest to the quality of their switch of choice with audio routing? my a151 isn't the smoothest and i often hear pops and clicks. would love to find another that can handle audio more gracefully.

woah

I just got a Joranalogue Select 2. It's 2 cv processors, each of which can do track-and-hold, 2 input -> 1 output CV switching, etc. Haven't even taken it out of the box yet, but I think I'm going to love it.

Try placing a buffer immediately after the switch, it helps with the A-152.
mdoudoroff
Any switch could produce clicks and pops with audio unless there’s fancy (expensive) zero-crossing circuitry or some fancy (expensive) per-channel VCA action going on. I don’t know whether any such fancy (expensive) switches actually exist in the market. Mainly a problem with low frequency and sines, less a problem with stuff with harmonic content.
Dcramer
A-152, both CV and trigger controlled, 8 channels :
Frames, 4 channels of bidirectional switching, morphing, mixing/splitting thumbs up
hermbot
I love my RxMx for this. It can be a voltage controlled switch and/or crossfader. Or a mixer, or a low pass gate. And it has great synergy with both my DPO and FXDF.
lisa
RxMx is really expensive for someone looking for simple switch, though.

WMD SMM

https://www.wmdevices.com/products/sequential-switch-matrix

4 in 4 out switch matrix, with 16 matrix steps that can be sequenced.
bit heavy on the HP, but def an amazing tool for routing CV or Audio.
Buttons ARE toys
I've been getting a lot of mileage out of Macro Machines' Dynamic Destiny. It's dual channel, each switch can be 1 in 4 out or 4 in 1 out. What makes it great though are all the different modes it can run in--built in clock division, disabling of unneeded i/o, control over which direction the switch progresses including random and pendulum. It's discontinued but they pop up used pretty often.

Loads of cool options here, thanks.

I think my ideal module is very simple, 2 channels of switching, each one with two switchable inputs linked to a single output, toggled between via a trigger pulse. Basically a Doepfer A-150 but with the switching controlled by trigger pulses, rather than sustained voltage
https://m.thomann.de/gb/doepfer_a_150.htm

Any ideas? Ryo paths seems closest maybe

Doepfer a-151 (v2) will do this. It can be anywhere between 2 and 4 channels of switching (bi-directional). You can control the number of active channels by a toggle switch. Also you can do this with an Erica Pico Seqs but you use a voltage rather than a switch to control the active channels (which is a little more work but leads to some other cool possibilities). I have both of these switches and they are both great for different things. Sounds like for you the Doepfer a-151 might be the best fit though.

If you have the money go for ADDAC 206 switch, especially if you play live. The functionality and hands-on UI make it the best option out there. You can do 4:1 or 1:4, switch, pause, skip channels, change directions, all kinds of crazy. Plus it has on-board clock division! I have a lot of switches and that one is still my favorite.

not sure what you mean by buffer. but i thought of a way around it i'm going to try. was thinking i could, for a 4 in 1 out setup, send the out into an lpg and mult the audio so that it is the voltage to open it.

i was afraid of that. ah well, i don't use it for audio very often anyway. anyone comment on the SSM yet?

I thought you were concerned about audio quality degredation, in which case a buffer might help. It won’t eliminate clicks on switching.

For me it’s the Sputnik Selector, though I think they are only available second hand at this time.

+1 for RYO Path
4x4 switch trigger or voltage controlled

Clickless switch at audio rate. I had great fun switching waveforms using all waveforms of a vco @ ins and the pulse wave for trigger.

Recently, someone in another thread quoted Dieter Doepfer who stated in a customer e-mail that if you`d like eliminate clicks and pops completely, you would have to sacrifice the bidirectional signal path of the switch. There are various choices of unidirectional or voltage adressed switches, if that`s an option for you. Another possibility would be the humble A-144 Morph Controller into a dual or quad VCA. Use a fast enough CV to imitate switch behaviour without clicks.

I used to really like the clean layout and controls of the Malekko dual switch, but realistically the Doepfer dual Switch is much more versatile with its separate control for both Switches (even without the manual control button that Malekko provides).

My absolute fav Switch though is the mighty SSSR Labs SM010 Matrixarchate... which has now ended up controlling other VC switches hihi

what a beast.. i see a module with capabilities like that and hear mrs skinner saying "you fruits wouldn't know what to do with me!" what's something else you'd do with that besides switch switches?

You need a Switchblade.
It does exactly what you want, is not expensive and only 4hp!

Ryo paths.
4:4 switch is so much more fun than a 1:4 switch!

I'm not very familiar with switch modules, I'm looking for something very simple : a 'router' with CV.

Input A -> output A
Input B -> output B

That can be switched to

Input A -> Output B
Input B -> Output A

Is there a dedicated module for that? Any ideas to achieve that with other modules would be appreciated as well.
windspirit
I guess I'll throw my hat in the ring, check out Mystic Circuits Tree. You can use it as a normal 8 channel bidirectional sequential switch with the clock/ reset/ direction inputs, you can use the shift inputs as binary addressing inputs to temporarily shift between the inputs in a more algorithmic way, or you can use both sets of clock inputs simultaneously for a blend of both.

The simple Doepfer a-150 gives you 2 vc switches in 4hp and is pretty cheap if you want to patch this up.

WMD Sequencial Switch Matrix!

Might be larger and more expensive than you wanted but worth checking out the Qu Bit Synapse. I've got a few simpler switches like the Doepfer and 2HP and the more flexible Muxlicer but I keep using the Synapse as a central part of most of my patches.

It has clickless switching along with heaps of other features that take it further than most switches. Having the 2 inputs per channel expands the uses to vca's before switching or cross fading, then add on the memory locations and inertia fading between states and internal lfo's and it gets real deep.
mazzyboy
Another vote for RYO Paths. The way it rotates the outputs is really clever.
Super useful and actually changed the way I approach patching. One of my “cold dead hands” modules!

I use my mutamix as a switch for CV and Audio as well as the doepfer A150. Curious about the RXMX and Synapse. I guess those are more crossfaders...

Doepfer has a cute new quad passive manual switch, the A-182-2:

https://www.modulargrid.net/e/doepfer-a-182-2

It's smaller than the A-182-1 (4hp vs. 6hp) and (IMHO) more straightforward to use.

I have one in my rack and it comes in handy, especially for making comparisons between two options and for muting.

EDIT: just noticed the mention in the subject about CV-controlled switches, which this isn't. Sorry for being off-topic.
matthewryals
I'm using two different gate sequencers that trigger 4 drum modules. Right now I have to manually replug depending on which sequencer I use. So, I'm looking for a switch with four channels, each with two inputs at least & one output. This way I can switch between the sequencers live. I def need a manual switch, but CV would be nice too. I think the Doepfer A-182-2 is exactly what I need except it has no CV control. Am I right about this and do you know of any other switches that would get this accomplished? Thanks!

Thanks! A-150-8 looks great. A little large for performance case, but has more channels.
Joe_D
The Doepfer 150-8 is a really versatile tool. Yes it's a lot of real estate, but you can use it for so much more than the switching function you currently need. For instance, four switches could do your sequencer switching, and any of the other four can be a manual gate source in performance (just feed the second input a steady CV, and use toggle mode to fire off manual gates), a /2 clock divider, a square sub-oscillator, a baby wave splicer, or two switches can swap the routing of a pair of inputs to a pair of outputs, etc. And remember that it's bidirectional; it can switch two inputs to two outputs, or two inputs to one output, or two channels can be synced so that they simultaneously switch one 2->1 and one 1->2, (or any combination), which can let you make big changes between sections of music with just one manual or CV trigger (or gate, for switching back and forth between two complex patch states).

The only caveat is that V/oct CV's don't make it through unscathed; the resistors that make it able to be bidirectional mess up the V/oct levels. But I find it pretty easy to recover the squished voltage range to its proper V/oct relationship. Doepfer recommends going into a buffer. I often instead use an attenuverter or amplifier/mixer with gain to scale the CV back up after the switch (to tune it, I feed the A-150-8 a simple octave sequence, take the output to my gain module, take that output to the V/oct input of my oscillator, and then turn up the gain until the "octaves" are really octaves again -- takes a few seconds, and then I patch my "real" CV source into the A-150-8).

If you're interested in getting ideas about what you can do with a bunch of switches, here's a good switching ideas thread: https://www.muffwiggler.com/forum/viewtopic.php?t=120383)

Yeah, I tend to use one as a switch for sound sources, one for CV and one as a sequencer or a sub oscillator. Such a simple but clever module.
