Default Quickest way to crossfade between 100 items?

I wrote a program to morph two sounds. It outputs 100 or so samples, each the full length of the sounds being morphed. Sample 1 is instrument A, Sample 100 is instrument B, and the rest are the inbetween sounds.

So I want to crossfade from Sample 1 through the rest to Sample 100 to complete the morph. and back from 100 to 1, and rest around 50, etc.

Is there any quick way I can accomplish this in Reaper?

Close! But all the samples are of the same thing, so they should all be aligned to play at the same time, but with the mix playing only one at a time, and with automation to go through samples 1-100 (like with the modwheel or an envelope).

so you have two tracks with items of same length at the same position.

get the sws and reapack extensions.
there you find a script like 'x-raym copy region and put it at the end of the project', setting a keyboard shortcut to it for easier execution.

create a region over the items and press your keyboardshortcut 100 times. (Maybe you are able te create a script which loops from 1 to 100 performing the script)

create volume envelopes for Track 1 and 2 from beginning to end
Track 1 run from 0 to -inf
Track 2 run -inf to 0

ok, increasing in steps would be more exact but i guess that can be neglected, depends on the length of the items.

make a folder Track

render the folder track to mono or stereo muting the sources

render the result with region matrix to single files.

there you are (almost)

Maybe could you post screenshots for before-after quick demos that we can understand the situation a bit better ? :P
