Ensoniq SD-1

The Ensoniq SD-1 is a 61-key polyphonic digital synthesizer /w MIDI. It functions via a form of wavetable synthesis called additive synthesis, and has a maximum of 21 voices. There's an in-built dual effects processor, with reverb, flanging, chorus & delay. It also has an on-board 24-track sequencer, with capacity of 25000 notes, 60 sequences and 20 songs, and a disk drive for storage.

Tony Banks used an SD-1 on the The Way We Walk tour (promoting the We Can't Dance album) in 1992, replacing the VFX for synth sounds. On Strictly Inc., the SD-1 was used by Tony for mainly drum machine parts. He liked a lot of the SD-1's sounds, so a lot of those were kept on the record. It is most noticeable on "Something To Live For" and "Walls Of Sound", where the drum loops are a major foundation of the track.
