only just got a marbles but using it w/ teletype has been a load of fun. loaded in a 0 - 5 v custom scale that selects pitch values from a pattern and gives me the highly-intuitive spread / bias control of note distribution (with the option to offset or change patterns to work off a new set of pitch values). I also think, on the whole, this system might have too many audio sources for its size to work with sensitively (esp. if you’re using tt for just type functionality, which has quickly become most of the auditory meat of my 6u, since six oscillators through different fx channels + modulation of time really can feel like 6 distinct voices). also a little light on vcas for a system with so much stereo, imo.
might be worth looking into tt expanders, too, since they add so much functionality in SO. LITTLE. ROOM. the jokes about tt being complete system when you integrate expanders are only very mild exaggerations. it’s as deep as you’re willing to make it and can replace almost everything (like… I sold my octatrack and unracked my midi2cv once I hit the first tt proficiency plateau since I have a smaller / simpler / cheaper sampler and could get everything I wanted out of OT with txi + txo).
I’d recommend 16n for hands-on timbrel control. it feels soooo good.
have 0 x-pan experience (because I have two cold macs and 10 channels of vca besides) but it seems to do only one of the things it does (panorama) ‘better’ than other things, and it’s a very specific effect (although I feel similarly re: qpas vs 2 x 3s wrt resonant peaks so maybe you’re just into that sound – if so, groovy!).
