Good evening @Reese, @Johan, @STU-C and @all to whom it may concern,
I thought it over for some moments, relaxed and felt free at last to drop a line, phps. to comfort you all as follows:
I had my first gig at easter 1976 (aged 23 yo). Bonny M (Sunny) and others were the favorite artist. The first 12 incher occured: Undisputed Truth (you + me). Or Candy Staton’s Young hearts …
The DJ’s equipment contained two LENCO turntables, speed was possible to change and adjust.
Starting the duty when the sun was going down, finishing duty when the sun raised, and the birds were singing. And we had fun.
In the middle of 1978 beatmatching became favourite (counting BPM with the stop watch, chasing for the newest smashed hits, reading BILLBOARD’s discocharts very carefully and so on).
In autumn of 1978 TRINITY in HAM should be opend, but the opening was postponed to the end of the year 1978 and so Charon Lee visited the club, where I was the “resident DJ” at the weekend. She watched me at work and so we started chatting and I became the chance to have some lessons with her, thanks.
My last public gig was at the year ending party 1981, as I finished my education and there were no time left for DJ-ing. But I always bought some records, stored them and had a private equipment just for fun and hobby situated on the attic.
Ending 1997 I stopped this hobby as of my profession there was no time left for DJ-ing.
All the time there were no digital equipment but only VINYL and you had to rely on your feeling and ears for beatmatching. Pls. don’t ask me, how many transitions ended in “all mixed up” and the greatest success was, hearing successful transitons on the tape, recorded at night (Applause)
In the meantime I’m fading to grey and when CORONA locked down everything, so I decided in 2021 to digitize my Vinyl-Records, bought a P4 and started beatmatching and DJ-ing on nowadays standard.
Pls. believe me all, I’m really glad to create smooth transitions with the technique of today with those records sometimes elder than 45 years and at that time it was impossible to beatmatch them properly (now I know, why). Most of my friends and others are pushing me now to relaunch gigging 
, but I think, good idea, but better no way for some reasons.
It will be enough for me, visiting dance parties, being with you and let’s have fun.
The essence of this post may be that I’m really keen on, learning what kind of sound systems, features, tools, controllers and so on will be developed in future, what kind of experience you will make, what RGB-pattern “will be best” but I will be honestly glad, when we will be able for setting and improving the beat grid by hand or automatically. I’m sure, DENON’s staff is working on it with first priority.
So all have prosperous gigs, heat up the crowd and embrace the future with your equipment and all skills you have and at last enjoy beatmatching and have fun.
