Iāve got a VP-9000 and yeah, thereās nothing the OT (or any other sampler Iāve used in my life) can do that even comes close to the three or 4 things the VP-9000 does.
But on the other hand, the OT can do a few hundred things the VP canāt.
Your best bet (short of buying original hardware thatās not cheap like it was a few years ago) is probably to track down a copy of the Roland R-Mix software, use that for your Variphrase stuff, and then sample or load the results into the OT. Not ideal, but I think itās the only affordable way to get the actual Variphrase algorithms now. Iāve never actually used it myself, though, so I have no idea if itās any good or even if itās discontinued (I assume it is).
If you absolutely need a hardware option, the VariOS is the cheapest (but youāll still need a computer that can run the 20 year old software to actually program it, and even a VariOS is around $400 now, which is like double what the VP cost before people started to value gear from that era again.
Maybe the best option is to make a friend in Japan, because vintage gear is much cheaper on Yahoo Auctions Japan than anywhere else, but very few sellers will ship internationally so you need someone local to buy and test the stuff before shipping it to you. Depending on where you live, the shipping costs might offset the difference but the way global synth prices are right now maybe not. When I was shopping on there regularly for a little while in 2020 the stuff I saw was insane. Off the top of my head, some stuff I saw in just a couple weeks (the friend I had there moved before could get much) were $40 Akai S-1100, $1500 for two full racks of Roland System 100m modules, a Korg Mono/Poly that had fallen off of a stage and broken into to pieces for $1 (not a typo, it was actually a bit under a dollar and the same seller also had an even more broken SH-101 that was underneath it when it landed - both were unrepairable but had hundreds of dollars worth of salvageable rare parts inside, enough that even with nearly $200 shipping it would have been worth it for a professional tech). Iām sure itās higher now, like everywhere, but I jsut did a quick search and thereās a VP-9000 for $220 USD right now, which is pretty good compared to the $500-$1000 people ask on Reverb these days. If youāre looking for hardware and would rather deal with some hassle than spend North American/European prices, itās the way to go.
Almost everything designed to run at 100v will work just fine at 120v without modfication. Iāve been using the 100v Boss CE-300 rack chorus I bought on there for 80 bucks at 120v for maybe 5-10 hours a week for three years now and itās doing jsut fine (the power supply board inside is even marked 100v-240v, they just stenciled different voltages on the outside of the case depending on what region it was shipped to).
