TELEXo Teletype Expander

Other/unknown

The TELEXo (or TXo) is a 4HP Output Expander for the Monome Teletype

Each 4HP TXo module adds and additional 4 Trigger and 4 CV jacks to the Teletype. It has little jumpers on the back so you can hook more than one TXo (or its brother the TXi) to your Teletype simultaneously over the II bus (i2c).

All Teletype output functionality is supported by the TXo. 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 TXo starts with being able to specify longer values for slew and pulse times (in seconds and minutes).

The TXo 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 TXo’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.

The TXo is an Open Source module designed by bpcmusic.

These merchants probably sell this module. Huh?
