Turn any recording into a synthesizer! Now with support for Audiobus and MIDI.

MegaCurtisBig uses an unusual hybrid of wavetable and granular synthesis to create tones and timbres quite apart from the standard FM or subtractive synthesis fare. Add this app to your arsenal to create sounds you simply cannot squeeze out of any other synth, no matter how much you’ve twiddled its knobs.

Create a synthesizer from any recording, with endless tweaking possibilities. Play the sound forward, backward, or even at a single point! Unlike scratching a record, pitch doesn’t depend on how quickly you move through the recording.

You can load sounds through iTunes, record directly with your iPad, or paste audio from other applications. Try it with speech, singing, synths, jackhammers, or birds. Mangle your recordings or create soft, gentle textures.

What does MegaCurtis have that the old Curtis doesn't?

Smoother Grains • Makes the glitch a little less glitchy and makes the synth a little more tonal
Overlap Control • Successive grains can overlap for still more smoothness
More LFOs • Modulate position, pitch, volume, and overlap
Keyboard Scales • Set the keyboard to a musical scale for easier playability
Four Voices • Play chords

Filter Per Voice • Each voice now has its own lowpass filter

Cleaner Interface • Specifically tailored for the iPad
Folded Faders™ • More on this below

What's up with these weird square knobs?

The Folded Faders™ let you dial in 4096 steps of fine control in the space of 128 retina pixels. Instead of emulating a physical fader, which would only give you a maximum of 128 steps of control in the space provided, we've folded up the fader to lend you much more finesse. Move it slowly, and you can fine tune things in tiny increments, or move it quickly to easily make larger adjustments. It takes some getting used to, but ultimately you get far more control.

Coarse Control • Drag quickly
Fine Control • Drag slowly
Dual Axis • Drag left/right or up/down, whichever is more convenient

What’s New

Version 1.4.3

Fixes grain envelope and overlap calculations.

Interapp audio via audiobus = audiobus

Claims to have "interapp audio via audiobus" which seems to be simply audiobus with no actual interapp audio showing on the interapp audio menus. So If you have not purchased audiobus you don't have interapp audio. If the developer did not slap"tm" on everything this would be easier to overlook. The app itself is very cool take on granular synthesis and fun to play, and I happen to have audiobus so can play with other stuff. Actual interapp audio would be very welcome.

Ultra granular classic

The bigger bro to Curtis, and a nice sampling grain synth! I love all the old apps and they are crying for updates so let’s hope this is just the start. I mean donut was my favorite app. Anyhow this app is as glorious or twisted as your imagination seeks.

Not impressed

Update: With no update in 2 years, still no note hold, text font still ridiculously small, no new features of any kind. Why would I risk $9.99 on Soup Granular and again risk have this developer abandoning it too?
It's not an update. It's a separately sold app. Without note hold it hand cuffs your ability to do much since you have one hand tied up holding keys. The sound still has no punch.
