I typically use this when mixing acoustic (bands, singer/songwriters) material- but I imagine it could be used on anything.
I am a huge proponent of the PC tape module. I own the Kramer Tape plugin from waves (and i like it lots) but the PC module has become a staple of every project. I don't know if it's accurately modeled because I entered the fray in 1999- just as digital was taking over. But I am impressed by the weight and warmth added to any sound. The "smudge" and compression, while not for every situation, effectively take the digital sound out of digital recording and mixing. The "darkness" imposed by 7ips is partially and pleasantly restored by the console emulator placed after the tape (i prefer the Neve setting).
When tracking a band, i often use ONLY the process described here to create a rough mix. Clients have LOVED the vibe of these rough mixes. Full disclosure- I may also throw the vintage channel (preset "Master Mix") on the master bus for these rough mixes (not tot mention more tape saturation and a bus console emulator).
If you are pursuing neat, tidy, "clean" mixes, this may not be for you. If you are seeking fat, punchy, warm, slightly dirty (or downright filthy) mixes, give it a try.
I am working on several projects at the moment. When they are released, I will post links and info (in the appropriate forum area ;)
