The Erbe-Verb is more than a collection of reverb algorithms or presets, it is a unique, modeless, continuously variable reverb algorithm with complete voltage control. Typical reverb
types such as plate, room, hall, shimmer and others may be programmed by adjusting the knobs. The continuously variable algorithm allows for hybrid and unreal spaces to be found.
Traveling between spaces is possible by modulating the algorithm or manually sweeping parameters. More than an end-of-chain effects unit, it's a whole new building block for modular
synthesis. Like the Echophon, it's coded by Tom Erbe of Soundhack.

Try turning the DPO VCO A FREQ knob up and down to hear the full range of the oscillator. As you can hear it goes from really low,
so low you can’t even hear it, to really high, so high you might not be able to hear it.
What you’re probably wondering is, how can you turn that constant tone into a series of notes with beginnings and endings? One
way is to just turn the Optomix’s Channel 1 control up and down over and over again, but that would probably tire you out pretty
quickly. Let’s start bringing some
CV
(Control Voltage) into the mix.
To that end, let’s take a look at the MATHS. MATHS consists of four
channels of either voltage creation or modification, depending
on how it is patched. Set all four channel panel controls (the white
knobs down the center) to 12 o’clock. Also, set the Optomix Ch. 1
Control all the way up (full CW).
MATHS as a Lag Processor
Another way to use MATHS is as a
Lag Processor
or
Slew Limiter
. By patching a signal to the signal input on Ch. 1 or Ch. 4, any
change in the signal can be slowed down. The Rise and Fall controls can be used for independent Slew Rates, depending on
whether the voltage is rising or falling. A classic example: when a Logarithmic slew is used to control pitch, it is analogous to
the “Glide” or “Portamento” control on many keyboard synthesizers.

Basic use:
Patch any audio to input. Use panel controls to shape reverb sound. Monitor Output.
