“Pulled the lever on my Proteus 2000 for an hour and kept forty patches. Thought this was just going to generate random noise, but no most presets are usable and sound crazy!
Marcus T.★★★★★October 9, 2026
“Converted my whole Kontakt library to MPC keygroups overnight. Loaded the .xpm files on my MPC Key 61 and all samples play correctly across the keyboard.”
Used2That★★★★★October 1, 2026
“The Fantom-X editor alone was worth it. You can't get Roland's Fantom-X Editor on Mac anymore, so being able to make patches from Synth2Software has been great.”
Dre Holloway★★★★★September 30, 2026
“Made a Serum 2 bank with it, this thing generates crazy sounds.”
Modular★★★★★September 29, 2026
“Auto-sampled my Audity 2000 with three velocity layers and it mapped everything for me. Loaded straight into Kontakt.”
DJ Plugg★★★★★September 28, 2026
“My Xtreme Lead sat unused for years. Now I roll a few presets every session and actually use them.”
Shawn★★★★★September 27, 2026
“Expansion mode rolled 250 presets in one go and grouped them in the library. Named the bank and moved on.”
Tobias V.★★★★★September 26, 2026
“Runs inside FL Studio as a plug-in and drives Serum 2 from the slot machine. Didn't expect it to be this fun.”
beatsbyjules★★★★★September 25, 2026
“Category mode keeps the rolls usable. A few came out too wild for me, but the ♥ button sorts that out fast.”
Caleb Ortiz★★★★☆September 24, 2026
“The manual is properly written. Every screen explained, and the ? button opens it right where you are.”
Nadia R.★★★★★September 23, 2026
“Nothing gets written to the synth unless I press Save. That alone made me trust it with my XL-7.”
modularmoe★★★★★September 22, 2026
“Jackpot mode is ridiculous in the best way. Won a free week on my third day and rolled about 400 presets.”
Jonah W.★★★★★September 21, 2026
“I sample a lot of hardware for my own packs. The loop editor finds clean loop points I'd have spent ages on.”
Sofia M.★★★★★September 20, 2026
“Great on the Virus TI. Took me a minute to find the Synth Style setting, but the guided tour pointed it out.”
tapehiss★★★★☆September 19, 2026
“The Proteus filter rolls are the best I've heard from any randomizer. Real movement, not just noise.”
Andre P.★★★★★September 18, 2026
“Turned a folder of WAVs into a playable SFZ instrument in two clicks. Pitch detection got every note right.”
Kenji S.★★★★★September 17, 2026
“Dexed and the DX7 both work from the same tab. FM patches I'd never have programmed myself.”
Hannah L.★★★★★September 16, 2026
“Bought the desktop edition and the updates keep coming free. 7.0.0 felt like a whole new app.”
rackmountRay★★★★★September 15, 2026
“Really good converter. I'd love even more formats, but it already covers everything I load day to day.”
Lucia F.★★★★☆September 14, 2026
“The library keeps every roll, so I never lose the one I liked ten pulls ago. Hearts make it easy to find.”
Grant E.★★★★★September 13, 2026
“Basic mode on the Proteus is perfect for pads. Gentle changes, always playable, never boring.”
noisefloor★★★★★September 12, 2026
“Set up in ten minutes with my USB MIDI interface. Connected to the E-MU first try.”
Imani J.★★★★★September 11, 2026
“The plug-in in Ableton is now part of my writing routine. Pull, play, keep or skip. Fast.”
Felix D.★★★★★September 10, 2026
“Edits are deep on the E-MU side. The Korg editor is lighter, but the rolls there still sound great.”
chromaticChris★★★★☆September 9, 2026
“I run a small sample-pack label. Rename-to-program saved us from broken references in every format we ship.”
Bea N.★★★★★September 8, 2026
“Chaos mode on the Fantom made sounds my synth has genuinely never made. Some wild, some gold.”
Omar H.★★★★★September 7, 2026
“The design is beautiful. Dark, clean, feels like real hardware. And it's quick.”
velvetvoltage★★★★★September 6, 2026
“OsTIrus plus the randomizer is a deadly combo. Every pull is a fresh Virus patch.”
Rita C.★★★★★September 5, 2026
“Love the auto-sampler. Plug-in sampling took one try to set up, then it ran through 61 keys on its own.”
Victor A.★★★★☆September 4, 2026
“The free version let me check it worked with my Mo'Phatt before buying. It did, so I bought it.”
Ella Q.★★★★★September 3, 2026
“I mostly use the converter. Emulator X banks into Kontakt was the thing I'd been looking for for years.”
dustydrums★★★★★September 2, 2026
“The step LFO and arpeggiator editors on the Proteus are better than the front panel ever was.”
Samir B.★★★★★September 1, 2026
“Rolled a full bank for a client in an afternoon. They thought I'd spent a week programming it.”
Maya G.★★★★★August 31, 2026
“Solid tool. I'd like a light theme, but the theme maker lets me get close enough.”
Jesse Y.★★★★☆August 30, 2026
“The win line tells you what changed on every roll. I learned more about my synth in a week than in years.”
Wren I.★★★★★August 29, 2026
“Serum 2 rolls with real modulation and audible sources every time. No more silent patches.”
Paolo Z.★★★★★August 28, 2026
“Being able to sell my rolled expansions is a nice bonus. The banks look great with cover art.”
kiloHz★★★★★August 27, 2026
“The Korg M3 support is what sold me. Nobody else touches that synth.”
Leah O.★★★★★August 26, 2026
“Very good overall. The odds table in Jackpot took a read to understand, but the ? explains it.”
Bruno T.★★★★☆August 25, 2026
“I teach synthesis, and the editors make an E-MU's guts finally visible to students.”
Hazel V.★★★★★August 24, 2026
“The arpeggiator randomizing on the Fantom is pure inspiration. Instant loops to write over.”
arpeggiAlex★★★★★August 23, 2026
“Converted a SoundFont collection to Bitwig multisamples without touching a single file by hand.”
Nina P.★★★★★August 22, 2026
“Customer support answered fast and the fix was in the next update. Rare these days.”
Desmond K.★★★★★August 21, 2026
“Great value monthly. The yearly plan would be my pick if I'd known how much I'd use it.”
sinewaveSam★★★★☆August 20, 2026
“Sampled my Vintage Pro into a Korg KMP for my Kronos. It just worked.”
Ivy R.★★★★★August 19, 2026
“Four jobs in one app and none of them feel tacked on. The converter is as good as the randomizer.”
Theo M.★★★★★August 18, 2026
“My go-to for fresh sounds when I'm stuck. Ten pulls and there's always something to start a beat.”
Zara W.★★★★★August 17, 2026
“DX7 Chaos rolls are unhinged and I love it. Category mode reins it in when I need bass.”
fmfreak★★★★★August 16, 2026
“Works great on Windows and on my Mac. Took one evening to learn the basics, then it was all fun.”
Quentin L.★★★★☆August 15, 2026
“The velocity-layer capture is so clean. My sampled Proteus sounds like the real thing in Kontakt.”
Aaliyah S.★★★★★August 14, 2026
“The slot machine readouts make it feel like a game, but the presets are seriously usable.”
Ben F.★★★★★August 13, 2026
“Browser Studio means I can roll on the laptop at a friend's place with nothing installed.”
studio_c★★★★★August 12, 2026
“Imported my old .syx files and the library picked them right up next to my new rolls.”
Lorenzo G.★★★★★August 11, 2026
“A lot of features, so it takes a little learning. The guided tour on first launch helps a lot.”
Mei C.★★★★☆August 10, 2026
“Synth Style lets my Proteus roll in the style of a Fantom. Didn't know I needed that.”
Gideon A.★★★★★August 9, 2026
“Every update has added something real. Paying once and getting all this is a great deal.”
Polly H.★★★★★August 8, 2026
“The JUNO-DS tab rolls great leads. A couple of pulls and I had my hook.”
subharmonic★★★★★August 7, 2026
“Converted, sampled, rolled and edited all in one evening. This replaced three apps for me.”
Renee D.★★★★★August 6, 2026
“Love that it talks straight to the hardware over MIDI. No drivers, no editors from 2002.”
Kofi O.★★★★★August 5, 2026
“Really fun and really useful. I'd buy a second edition for my studio partner without thinking.”
