Hello and Happy Holidays!
Here are my thoughts for two Teletype expanders that will address some of the requests in this thread (and also be things that I’d like to build and have). Both would connect over the II bus and integrate with the Teletype using new remote commands listed below. Telex 1 provides the Teletype with 4 additional trigger outputs and 4 additional CV outputs. Telex 2 is a collection of six parameter knobs that can be read from the Teletype.
I am very confident that Telex 1 can be implemented with ease on the Teletype side; Telex 2, while seeming simpler from a commands point of view, implements a pattern that I’ve not experienced with the Teletype - polling a remote device and returning a value. While anything is possible, I’ve not yet put on a snorkel and probed around in the source code to see if it is supported today and, if it isn’t, what effort would be required to get it there. (Depending on the outcome of this research, I’d also like to implement a Telex 3 that allows the Teletype to poll a collection of additional CV inputs. However, I’ll save work on that until after I’ve made some headway with Telex 1 and 2.)
I’ve endeavored to keep the layout style as similar to the existing Monome line of modules as possible. To make it a reasonable DIY project, I’m planning to design it at 4HP for each module to give space for through-hole components, skiff-friendliness and approachable assembly. The logic board will be a Teensy microcontroller that mounts to one of two stacked PCBs behind the faceplate of the unit.
All commands below require the II command to precede them.
