The MOTM-510 is a new kind of analog signal processing module.
It's not easy to describe what it does, but I'll try.
Let's start with the well-known Ring Modulator (like the MOTM-110
or MOTM-190). A Ring Modulator is a multiplier: the output can
be written as Out = X * Y, where X and Y are the 2 input signals
(sometimes referred to as the modulator and the carrier). X and/or
Y can be audio or DC signals. The output is simply the voltage
X times the voltage Y. This produces the sum of X and Y (X+Y)
and the difference of X and Y (X-Y).
The traditional RM has no 'control voltage' inputs: you just feed
2 signals in, and get 1 signal out. The MOTM-510 takes this concept
and generates entire new types of waveforms.
Instead of the 2 RM inputs, the basic WaveWarper has 3: X, Y and
Z. These are audio inputs. The transfer function is OUT = X *
- X is the GAIN signal. It controls the overall amplitude of the signal
- Y is the 'main audio' signal, the one that is getting 'warped'
- Z is the DIVISOR signal. This is acts to modulate the amplitude of the main audio
signal before it gets warped
- m is the Warp Factor. This is a fixed exponential factor, which is what is doing the 'warping'. No,
it's not voltage controlled.
- m varies (by the FACTOR control) from 0.2 to 0.6 (ROOT mode),
1 (UNITY, which makes it similar to a RM), to 2 to 5 (POWER mode)
- each input (X, Y and Z) has attenuators
- the AUDIO OUT is AC-coupled and band-limited to 18Khz. The FULL
OUT is DC-coupled and can go as high as 200Khz!
But wait, there's more! There are 3 DC-coupled inputs called OFFSET.
These can be DC control voltages (LFOs, EGs, etc) that add to
the audio signals. In this manner, the WaveWarper can respond
to 6 different modulation sources simultaneously.
Great....what does this MEAN? Well, it makes an absolute mess of even the simplest waveform. Effects range from frying bacon
to a frog in a blender to sticking your head into a jet engine.
You can warp LFOs into bizarre new waveforms, as well as the output
of MOTM-800 EGs. You can process any line-level audio. Hours of
NOTE TO KIT BUILDERS - this kit contains an expensive IC. A REALLY expensive IC. It is in a socket, but will NOT survive if you
put it in backwards. A replacement chip is $60.
