Suzanne Ciani

In this videoclip of 1980, you can see that she plays a Phophet 5 synthesizer,

Per Suzanne's interview with Women in Sound Feb 4, 2019:

I use Digital Performer if I’m recording and a MOTU interface. I have a Genelec quad [loudspeaker] setup that I love. I have a Focusrite preamp that I love for my piano. I have a nice [Neumann] U87 that I brought from my New York studio. I use a matched pair of Schoeps [microphones] on the piano. My bowed Vocoder is still sitting there. There’s a storage space downstairs where I keep other instruments that I can bring up to the studio. I might have one other instrument like a [Sequential] Prophet 6 on a stand. I had a Moog One here last week. That was pretty big. I’m into minimalism.

In this photo you can notice the Synclavier II with monitor console. On the top of the monitor you can see a vintage rack version of Eventide SP2016 Reverb.

In a user-uploaded photo from Electronicbeats, Suzanne Ciani is seen with the ARP Omni Mark 1 Synthesizer prominently positioned at the center.

Evidently this lengthy ongoing project will involve Suzanne reverting back to her compact and bijou collection of electronic instruments, with the 88‑note Kurzweil K2500 taking centre stage as the master keyboard controller: "I used to have these very strong opinions about different manufacturers and I always said I'd never use a Kurzweil. I just didn't like the sound. Then when I moved into this house, before I had my equipment sent from New York, Joe loaned me his Kurzweil, and it won me over. I started investigating, got involved and started talking with the Kurzweil people. I found them to be a very dedicated and excellent company. I like the way they do business and where they're coming from. They really do care, and the K2500 and K2000 are both sophisticated instruments with a lot of depth. So I'm a Kurzweil convert!

"I'm very fond of these 'orchestras‑in‑a‑box' like the Proteus 2 — on which I wrote Dream Suite — and I'm trying out Roland's new MCC10 Orchestral module at the moment. I get a big kick out of opening up something and taking out an instrument that weighs only 10 ounces! I want something which I can carry over my shoulder, so I've just got a tiny little portable Korg, because one of my needs is to be able to write whilst on the road. I like Korg machines too. I like the company and what they do."
