Synthesizers/Keyboards:

ARP 2600 (custom) w/ ARP 3620 LFO keyboard
(the one with the `bad´ filter... oh, this is utter nonsense, this machine is a killer!)

Korg PE-1000 Polyphonic Ensemble
(weird and characterful...)

Korg PE-2000 Polyphonic Ensemble "Orchestra"
(x2, two out of approx. six units in existence in Germany)

Mini Moog Model D

Moog Prodigy (custom)

PPG 1020 Synthesizer
(ex Alex Oriental Experience, Ser. No. 36)

PPG Wave Computer 360-A

(eight voices, earlier production run, currently being fixed, ser. No. 037)

Sequencers/Rhythm Units:

ARP Sequencer (x2, Models 1621 and 1623)

(custom, punchcard-controlled rhythm machine, the first programmable one with memories,
ca. 1974/75, see Ashra/Jean Michel Jarre. One out of approx. 15 units ever made)

Korg KMS-30 MIDI/DIN-Sync/Tape Synchronizer

Korg MP-7 Mini Pops (custom, w/ trigger ins and outs)

Mattel Synsonics (custom, w/ trigger inputs)

PPG 350 Computer Sequencer (custom; iffy as hell, but that´s not surprising as it´s a PPG...)

Roland TR-808 Rhythm Composer

Stompboxes:

Boss CE-1 Chorus Ensemble (x2; one of them was formerly used by NOVALIS)

Electro Harmonix Small Stone Phase Shifter (x2, one autographed by JM Jarre... seriously)

Electro Harmonix Electric Mistress Deluxe Flanger

Electro Harmonix Big Muff Pi Fuzz

Electro Harmonix Echoflanger (1977)

Electro Harmonix Polyflange

Electro Harmonix Polyphase (x2, heavily used on "Frozen Radios", running a Solina through it)

Electro Harmonix Bass Micro Synthesizer

Electro Harmonix Frequency Analyzer Ringmodulator (x2; this is another killer)

Other Effects and Processors:

AKG BX-15 Stereo Spring Reverb

Boss RPS-10 Digital Delay/Pitch Shifter (x2)

Lexicon Jam Man (32 Sec.)

Maestro USS-1 Universal Synthesizer System (a really wild and weird processor)

MXR Flanger/Doubler (rubberband sound)

MXR Pitch Transposer with display (forget Eventide)

Roland DEP-3 Reverb

Roland PH-830 Stereo Phase Shifter
(cleaner and more analytical than, say, a Moog 12 Stage Phaser or a Biphase)

Roland RE-201 Space Echo
(instant dub, and very musical even when it´s going into apeshit resonance)

Roland RE-301 Chorus Echo
(x2; this is my favourite one for strange lo-fi ambient loops)

Roland SDD-320 Dimension D
(so subtle it´s almost unnoticeable, but I guess that´s the secret about
and the reason for its desireability... if that´s a word )

Roland SDE-330 Stereo Dimensional Delay
(the RSS-tag certainly was a trick to woe many buyers...)

Roland SRE-555 Chorus Echo
(Q: How do you make a mix even more spacious?)

Roland SRV-330 Stereo Dimensional Reverb
(if that´s what RSS was all about it´s not much, but it´s still great)

(x2, essential if you´re using a lot of noisy bastards)

Schulte Compact Phasing "A"
(x3, various models, two of them were formerly owned by NOVALIS)
