I downloaded and installed the current version of Reaper and got it working . . .

THOUGHTS

I have not used Reaper in several years, and it never made a lot of sense to me . . .

So I used a technique and strategy I learned when I was working on the NASA Space Shuttle Mission Simulator, which at the time had the largest UNIVAC 1100 computers in the world and a virtual festival of Interdata computers that were clones of IBM 360 mainframes . . .

It was an amazingly complex system of hardware and software, and if it stopped working there were a handful of people (hardware and software) who would fix whatever the problem happened to be.

I was fresh out of college (Computer Science, although at the time it was Mathematics since there was no Computer Science major, this being a new thing in those days, late-1970s and early-1980s); and the manager for UNIVAC, which was where I worked, was one of the handful of people who were called when everything stopped working.

He let me watch what he did, and I asked "How do you find the problem?" and "How do you know how all this stuff works?" . . .

His response surprised me and it was an epiphany . , ,

He told me (a) he didn't understand the simulation system and all its hardware and software, so (b) he did something he called "scouting around", where the technique was to look at things until something did not look right, which likely meant it was the source of the problem . . .

There is a bit more to it, but that is the general concept . . .

This is what I did to make sufficient sense of Reaper to get it sending MIDI directly to NOTION 6 to play the NOTION 6 native piano . . .

Along the way, I read some of the Reaper User Guide and watched two YouTube videos, one of which was found by searching on "sending MIDI from Reaper to NOTION" or something similar . . .



I already had found the Reaper Virtual MIDI Keyboard and somehow had used it to record a MIDI sequence in Reaper on what I think is an Instrument Track . . .

The YouTube video was key, and from it I realized the importance of the little "Routing" icon on the Reaper track . . .

I set everything that made sense to me in Reaper; saved Reaper; reopened Reaper; and started my NOTION experiment project--the one that works nicely with MidiKeys . . .

I set some things in Reaper for the Instrument Track and it started sending MIDI to NOTION just like MidiKeys does . . .

At the moment, I know what I did but not in an immediately conscious way that is easy to document . . .

It works, and I can send MIDI from Reaper to NOTION . . .

I will make sense of what I did and then post a follow-up with detailed steps, and I might make a YouTube video . . .

[NOTE: This is the YouTube video, and it's focused on showing the various ways I configured NOTION and Reaper to make sending MIDI from Reaper to NOTION work . . . ]



Lots of FUN!

P. S. In some respects "scouting around" is like playing an instrument "by ear", where you click on stuff until it sounds good . . .

It's a conceptual type of thing and after you do it for a few years, you learn things that make it work better--few if any of which are documented anywhere . . .

On the Mac, part of the "scouting around" strategy is to click on stuff in an intelligent way until whatever you want to do starts working, which is fabulous . . .

Fabulous!
