Very kind to you, indeed good ideas but development and richer harmonies misses, was because I wanted to modulate in more keys, after some time the initial idea is lost !
Sometime I do better than that indeed.
I have yet to listen and try to do something with some ideas, in fact I have that recorder recently so I am not used to record improvisations, but I just had a version of a good software to write music, so that's an idea I'll keep for someday (when repairing pianos will leave me a bit more time !)
I am just uploading another improvisation recorded, that time on a very small vertical piano : Hoffman 104 cm - 41 inches tall (year 1985) a very fine German piano coming from a factory that closed in 1991 (the brand is now owned by Bechstein but the instrumensts are completely different from those ones) Tropicalized, very nice also.
I'll send the link in a moment (again a wav file 40 Mo)

Thanks for your comments, it is pleasing !
