Mixwitch

Mixer & Switcher

Dual 2 to 1 mixers, normalized into 4 to 1
- Click-less mute per mixer
- Click-less polarity inversion per input with LED indication
- Modulation vs. audio mode selection (lin/log) per mixer, with change of potentiometer curve response and LED indication.
- Two LEDs on each output showing the amplitude and polarity of the output signal
- Unconnected inputs present a fixed voltage to ease offset creation
- Full range DC-coupled analog signal path
Switch/Selector
- Switch among 4 inputs, only 2, or disabled
- Select an input sequentially with a clock/trigger
- Select an input randomly with a clock/trigger
- Select an input in relation to a control voltage
- CV and clock control are audio rate capable
Settings retained over the power cycle
High-quality potentiometers with metal shaft
Eloxal printed aluminium (silver panel)
or bath anodized brushed aluminium (black panel)
Skiff-friendly & compact module

"Standout modules of the last couple of years?"

This is the post/query on Mod Wiggler's forum where the Mixwitch was mentioned as "the most clever module you can get dollarwise".

It's a deceptively deep little module.

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

Super useful for feedback loops!
I only had one for a couple of days before buying another.

Some options like the Mixwitch are really flexible and have me thinking outside the box.
I like that.

Love the clocked random switcher to offset pitch. Inject a little LFO CV for movement.
It has so many functions it is absolutely briliant.
In another patch it can be an half Audio mixer / half CV mixer with clock / CV switching on the B inputs.
The list goes on.

If I go beyond oscillators there are tons of modules of great value.
Klavis Mixwitch is the greatest though.
I have three of them and I wouldn’t say no to another one.

It’s small, relatively inexpensive, has log or linear response, can be configured as 4:1 or 2:1, provides voltage out per channel, and can be stepped clicklessly per channel in a variety of ways.
It’s a super useful module.

...the best must be Klavis Mixwitch.
Mixer/switch/sequencer/etc in a clever, sturdy package for very little money

... i love the density of functions, and the well thought design!

Mixwitch applications described in the manual

1. Control signal mixer

with pots acting linear
2. Audio mixer

with pots acting logarithmically and mix level muted by 6dB
3. Four step sequencer/randomizer

generating CVs for a sequential or random melody set by the 4 pots
4. Simple sub-octave generator

using only one half of the module
5. Complex sub-octaves generator

one and two octaves below freely mixed and tweaked
6. Simple granular synthesis

using any VCO with multiple wave outputs
7. Multiple-segment waveshaper

fill each quarter-wave with other waves segments
8. Phase-controlled wave-stitcher

using PWM for control and a pair of audio sources
9. Voltage controlled transposer

to up to 3 or 5 independent tunings
10. Drum randomizer

in combination with some rhythm pattern generator
11. Digital inverter / signal amplifier

using one half of the module
12. Voltage window comparator

does switching/gating when a signal is within a specific range
13. Drum selection in sequencing applications

using one CV/gate pair for 4 drum sounds
14. Random clocking – Chance generator

with settable occurrence
15. Two-input logic AND / NAND gate

for digital duties
16. Two-input logic XOR gate – Digital ring-modulator

for exclusive selection or MS20-like ring mod
17. Saw to PWM with manual or CV control

for audio shaping or LFO gate length adjustment
18. Hard clipping

for audio shaping and distortion

Focused versatility seems an oxymoron when describing the features that led us to design the Mixwitch.
With only a pinch of mixing, inverting and controlled switching, we brew up a plethora of combinations and uses.
This is voltage processing magic!

The Mixwitch design comes from a frustration with attenuvertors (bipolar attenuators-inverters) whose off (neutral) position is difficult to retrieve, especially in live situations.
We went for a digitally-controlled analog path where polarity inversion would be at the touch of a button. So, the usefulness of attenuating/inverting can be realized by turning the pot down, swiftly pressing the inversion button and reopening the level. The zero level is where you expect it, with the pot full down.
Once we had a clean polarity control, we easily added a mute function offering the benefit of pre- adjusted pot settings ready to be activated at will.
The next step was to bring something extra, useful and creative. There are plenty of analog switches controlled by a clock; but arbitrarily selecting an input with a voltage is less known. Having both control capabilities combined with our specific mixer features creates a unique fusion: welcome to the Mixwitch !
