Mainly Protools LE, but sometimes Logic Studio.

The converters are an important part of the recording chain. I use a Digidesign 002R, but rarely use the converters. I have an RME ADI-8 for the converters - big difference.

Have used in the past: Cubase, Digital Performer, Cakewalk (pre-Sonar. The first CD I produced for an artist (Jon Batson) was done using Cubase back when it was called Cubase VST.
