Description
Each TTO module adds and additional 4 Trigger and 4 CV jacks to the TT4U. It has little jumpers on the back so you can hook more than one TTO (or its brother the TTI) to your TT4U simultaneously over the II bus (i2c).
All TT4U output functionality is supported by the TTO. Operators are near-identical for basic functionality, just put a “TO.” in front of the set you already know. The outputs are a little different; the triggers are +5V triggers and the CV outputs are bipolar (-10V to +10v) with 16 bit resolution over that range.
Extended functionality of the TTO starts with being able to specify longer values for slew and pulse times (in seconds and minutes).
The TTO also has the following “experimental” features for each of its four CV outputs:
-
a quantizer with a dozen or so microtonal scales in addition to equal temperament
-
an oscillator (not currently band-limited) that supports frequencies from LFO rates up to around 8kHz with variable waveforms (sine, triangle, saw, variable width square, and noise), and frequency slew (portamento)
-
an AR (attack + release) envelope generator with times in milliseconds, seconds and minutes
These extended features, when combined together, can really push the envelope of the TTO’s processor and do some crazy stuff. For example: the output’s envelope generator can act as a VCA, which turns the expander into a little 4-voice synth.
