Just found this thread, so I'm a little late to the party, but it's interesting to hear what other people are messing about with. That's a great setup you have Mr. Bentley, I'm very envious, but since all I do at the moment is noodle it'd be wasted on me anyway.
I've been using Max since '92, and love it. It's like a Lego kit or erector set or Swiss Army knife, but for MIDI and audio. Very much looking forward to Max 4 Live.
I had a TI-99/4A as a kid, too. I remember trying to program music on it and being really disappointed at the boring sounds I got out of it (this was long before I knew what a sine wave was...) No memory upgrade or disk drive, unfortunately, but I did have Extended Basic and the speech synthesizer (the novelty of which wore off quickly).
My gear:
kinetic instruments:
Reverend Daredevil electric guitar (Gibson-y stuff)
Schecter Hellcat electric guitar (Fender-y stuff)
Schecter Hellcat VI six-string bass
Shergold Marathon 6 six-string bass
Yamaha BB1200S electric bass
DeArmond Starfire semihollow bass
electronic instruments:
Korg Wavestation EX keyboard
Access Virus b synth
E-mu XL-7 Command Station sequencer/drum machine
(ROMs maxed out)
Fractal Audio Axe-Fx preamp/effects processor
ElectroHarmonix Clone Theory (I've got 3, for some reason)
Soundcraft Compact10 mixer (mostly for running things through the stereo)
MacBook Pro running:
Ableton Live 8
Cycling 74 Max/MSP
Logic (don't use it much)
Soundtrack Pro (ditto)
I need a vocal mic, if anyone has any recommendations, and will probably be getting a MOTU Firewire interface and an Akai APC-40 in the near future. I'd like to add a Virus TI and a Prophet 08 at some point, but I can't really justify those at the moment.
Other than Sampler and some "LE" versions of a couple software synths I haven't tried yet I don't have much of anything in the way of plugins - like our good Doctor here I like using hardware, at least for the sound-generating part of the chain.
