The voice in this musical composition is Marilyn Chambers from "Behind the Green Door" I sampled it about 20 years ago and uploaded it into an Ensoniq Mirage sampler. Its been sitting around ever since waiting for me to do something with it.
The guitar part and the clavinet part were actually recorded about 15 years ago on 4 track tape - also using an Ensoniq Mirage - so both the guitar and clavinet are "sampled."
I have a very high end, 32 bit, audio card in my new computer and can simultaneously record up to 8 instruments/voices at a time directly to hard disk (the card does analog to digital conversion).
I hooked up my old 4 track machine to the computer and digitized the guitar, clavinet and Marilyn Chambers sample (by sampling her voice onto a keyboard I was able to play her voice as a musical instrument creating harmonies, melodies, etc...).
I used Cubase VST 24 to bring the recordings into the computer in a format I could then manipulate it in. Cubase is a high end music program that pretty much puts at my hands everything that the large hardware based studios have. Years ago I used to record in studios that had mountains of equipment - I now have virtual versions of all those mixing boards, effect boxes, reverb chambers, etc...
I saved the files then re-opened them in a sound edit program called Sound Forge (by Sonic Foundry) - I used a noise reduction filter to remove all the tape hiss (which was considerable considering the age of the original recordings). I then used EQ to replace the high end that was cut off when removing the hiss (without adding new hiss - digital is WONDERFUL!).
I saved the file and opened it once more in Cubase. In Cubase I then added reverb, chorus and delay to Marilyn's voice. I added chorus, delay, distortion, autopan, "symphonic" effect, and other effects in various combinations to the guitar and clavinet parts.
I then mixed the 3 parts down to stereo, saved the file and opened it in another program called Acid (also by Sonic Foundry). In Acid I then added the drum parts.
I did a final mix. Converted it to MP3 and submitted it to Literotica.
