Almost all the parts you hear are being played in real time by "true" instruments. Keith generates 4 midi voices at any one time (including the banjo sample on Runaway) from his guitar, a "true" instrument. Andy generates 2 voices with the trumpet except one of the two can be a complex loop he assembles piece by piece from his trumpet in real time while the other can be a series of layers of sound. The melodeon is a "true" instrument. We do it this way because I want a trio. I want a trio because that is the optimum number of people for an improvising group. All the electronics you hear are being played. They are not sequenced or programmed or pre-recorded. We are a synthesis of "true" and electronic voices. That's what I wanted. And the percentage you quote is much nearer 50/50 than you realize.
Furthermore, most of the album is recorded live. Andy & Keith recorded their parts together with very minimal overdubs. I recorded the vocals within 6 passes. I took the tapes and re-recorded them to get the sound the way I wanted it but the performances themselves were in real time, standing there next to each other and playing. There are usually no more than 4-6 instrument tracks in any one song but I do alot of re-amping in the studio, generating 4-6 "copies" of every one of those original tracks. I spend time getting the space to sound right. I use a number of different mics. I don't use EQ at all. Instead Paul Hamann and I have invented a range of unconventional mics to achieve a banding effect across the frequency range that not only gives us good scale info but also allows us to bypass the eq stage. I only use spring reverbs and echo plates. I look for any chance to use passive filters. The album was recorded more live and with fewer studio digital effects (actually none!), I suggest, than the overwhelming number of "real" bands you might be thinking of. You may be mistaking the many voices we generate for overdubs or technical tricks. They aren't. We use the technology that others use for tricks but we use it in REAL time and we don't play tricks with it. Other musicians who see what we're doing are startled.
