Dees:
I've got a Waldorf pulse as well... it's the absolute KILLER for boomy analog bass sounds... it is used on most basses on that 70MB clip of my riffs posted another place in this forum... For doing jarre'ish basses it's the best I've got, but the presets in ROM does nothing for the synth, you'll have to do them yourself to provoke those bad ass low freqs!
Also, if you have listened to DRAX' basses on the real C64 6581 SID chip, the Pulse will punch those basslines off like no other synth would! ... I love my Pulse to death, and it'll NEVER EVER EVER leave my studio!
I'll have to take my words back about the Miniworks 4-pole though... it's NOT the pulse filter! ... in fact it's the same CEM filter as in the Waldorf Microwave version 1 (the later model wich have more fat filters) and also those found in the Waldorf flagship WAVE synthesizer... I also have the microwave 1, so you could argue why I'm holding on to this baby (4-pole), but one REALLY nice feature of this machine is, that it has a gain knob... and it allows you to overdrive the CEM filter wildly, and I tell you! with a nice saturation of the input to this filter, make the sound very dirty and "oldstyle"... if you need Jarre sound ala Oxygene, Equinoxe, then this little beast simply rocks!
Basicaly, the 4-pole is a "pulse" without oscillators... though not totaly... it got it's own charm, and that's why I won't let it go
If I may recommend another old hybrid synth, I'd have to mention the Ensoniq ESQ-1... This synth also have CEM filters and is 8 voice polyphonic (and multitimbral), and if I recall right, it's the same filters as in the Prophet 5. This beast is extremely flexible and has a really dirty fat sound with snarling resonance. and the fact that this machine is the first work Bob Yannes did after leaving Commodore (after doin' the SID chip) makes it kind of nostalgic to this scene as well... it's the creator of our beloved SID chip who made this machine!!! ... I'm looking for the Rackmount version (Esq-m) at the moment to replace the keyboard version, as it takes up a lot of space.
Also, just to talk a bit about the "clock radio"... I've done some bass patches and man this thing rocks! ... go home DX7! ... it's old-FM at it's best! I just love those old dance-bass sounds done on early FM gear... so punchy! (read: TX81Z Lately Bass), and these small beasts (FB-01) are so cheap you can sometimes find them for the price below US$50 ... they are way underrated if you just take the sound-design in your own hands. I'll post a clip here soon.
