MDP2 Auto-Step (Auto-Repeat) using MIDI Fire StreamByter

Question

MIDI Target Manufacturer(s): Original, Generic

StreamByter is a versatile plugin to control MIDI messages entering and exiting MIDI Designer Pro 2 (MDP2). StreamByter available in the MIDI Fire app allows it to detect, process, and feedback controls from/to MDP. It provide capabilities not available in MDP2 alone.

A short time ago I was asked to support a musician to develop a way to switch an expression pedal between several different devices using MIDI Designer Pro 2 and MIDI Fire StreamByter (SB). He was referred to my earlier layout for “How to Switch a MIDI Stream On and Off” in MDP Q&A. See https://mididesigner.com/qa/8794/how-to-switch-a-midi-stream-on-and-off?show=8794#q8794

After working out a solution for his configuration, I put on my Engineer’s hat and began thinking about the solution and how it might be used for other applications. I recognized that the approach was similar to an electronic timer using feedback to maintain a continuous stream of data. I began to wonder if anyone came up with an approach to create a timer. Searching MDP Q&A turned up a request for a clock that hasn’t been implemented. I saw another request for a  Stepper auto-repeat in 2014. See https://mididesigner.com/qa/3520/stepper-auto-repeat

It struck me that this may be a desirable feature. So I designed this MDP2 Auto-Step Hack to repeat stepping while a button was held down. At the same time, it needs to operate as a single step button with a quick tap. Several possible variations are included in the variations tab. The StreamByter code is listed in the last 2 tabs.

The video provides details on the design and operation of the layout.

This is all over my head, but I think that this is solved in the new Beta for 2.330 where we provide MIDI Feedback.

Allow MIDI messages to feedback to MD (Sysex message must start with F0 00 01 7E 77)

Thanks!

Not sure how this is implemented. My "hack" implemented  the required function. How does the new MIDI Feedback work? I know there is an issue with feedback in certain configurations. Does this allow feedback within MDP? Does it still require MIDIFire to provide a repeating output when a button is held down?
