TELEXi Teletype Expander
The TELEXi (or TXi) is an Open Source, 4HP Input Expander for the Monome Teletype.
Each 4HP TXi module adds 4 IN jacks and 4 PARAM knobs to the Teletype. It has little jumpers on the back so you can hook more than one TXi (or its brother the TXo) to your Teletype simultaneously over the II bus (i2c).
The IN jacks are bipolar (-10V to +10V). They work just like the Teletype IN and PARAM operators (TI.IN and TI.PARAM). It also has some extended functionality where the TXi can do quantization for you and return note numbers against any one of its internal scales (there are about 12 or so). Inputs are sampled with 13bit resolution.

The TXi is an Open Source module. Build one yourself or hack the firmware; all details are on the TELEX GitHub Project Site.
