Klaus Doldinger was one of the first musicians in Germany to own and use a Fairlight C.M.I. ( C.M.I = computer musical instrument ), the first ever sampling synthesizer and digital recording device, that came on the market at the end of the seventies and was quite expensive at the time, costing something from 40000 up to 220000 Deutsche Mark at the time. I'm German and I still remember quite a row of documentaries, which had been shown on German TV at the time about the making of the movie. It was co-produced by the ARD/WDR, one of the two public broadcasting and TV stations at the time in Germany, and since this was the biggest budgeted ever produced movie up to that time in Germany it was quite a lot reported about at the time in German television. Among the several documetaries I still remember is one about Klaus Doldinger in his studio in Munich working on the score for "Das Boot". You could clearly see him working with his Prophet V Synthesizer and his Fairlight C.M I., whose then state of the art sampling functions he explained and demonstrated in detail. Those stomping sounds, evocating the sound of the diesel engine of the submarine, and those plings, reminding of the sonar, were all done with the Fairlight C.M.I.. Then the docu showed Doldinger conducting a string section, which consisted foremost of real cellos, and a drummer, a timpanist and a percussionist, who all played along the pre-recorded synth layers. Very innovative indeed at the time, this early crossover of natural sounds and synthesizers and Fairlight samplings. Such much and quite literally over years the German TV reported about the making of "Das Boot", that after some time I myself got quite annoyed about it, and in all honesty I finally came to the conclusion that this movie would probably never ever get finished and see the light of the day, a fear that many German media shared at the time, because the tales about the constant failures and problems in filming it seemed utterly endless. At the time of the movie's final theatrical release, after over three years of production, everyone was completely baffled: What ?!! They did finally finished this catastrophy of a movie, REALLY, DID THEY...?! It was an absolute miracle indeed ! 😄👍🏻
Ha ha they won't catch us we'll be victorious! greatest and most realistic submarine...ever. Not so fun fact most U-boat crew died not from combat but from salt water getting to the batteries which created a deadly colourless olderless gas. Chlorine I think it was.
