Turn your iPhone or iPad into a guitar rig. Simple NAM Chain plays amp captures in the Neural Amp Modeler format, including A1 and A2. Load a capture, add a cabinet impulse response, and play. It runs on its own, or as an Audio Unit inside GarageBand, AUM and other hosts. BUILD A CHAIN Stack up to six blocks in series — a drive pedal into an amp head into a cab, or whatever order you want. Drag to reorder, bypass any block, remove the ones you don't need. Tag each one Full Rig, Amp Head, Pedal, Outboard or IR so the chain reads at a glance. EVERY BLOCK IS A FULL RIG Each block has its own input level, noise gate, amp capture, cabinet IR, three-band EQ and output level. The gate, the EQ and the IR each switch off independently. LOAD WHOLE MODEL PACKS Captures usually arrive as a folder holding the same amp at a range of settings. Point the app at the folder and step through every capture with the arrows, without going back to a file browser between takes. Keep your packs anywhere on the device, or drop them into the Full Rig, Amp Head, Pedal, Outboard and IR folders the app creates for you in Files. GAIN STAGING HANDLED Captures that carry calibration data are gain-staged automatically as you reorder the chain, so stacking blocks doesn't wreck your levels. Set your interface's input level in dBu once, and pick Raw, Normalized or Calibrated output. ALSO INCLUDED • Built-in tuner • Slim control, to trade a little accuracy for lower CPU on captures that support it • Live CPU readout • Recovers cleanly from phone calls, route changes and unplugged interfaces WHAT YOU NEED An audio interface to plug your guitar into gives the best results — the built-in microphone works, but isn't meant for playing. You'll need captures in .nam format (A1 and A2 are both supported), and impulse responses as .wav files if you want cabinets; thousands are free at tone3000.com. Headphones or monitors, so the mic doesn't feed back. FREE FOR THREE DAYS Everything is unlocked for three days. After that the app stops processing audio until you unlock it, which is a single payment of $4.99. Not a subscription, no accounts, no ads, and nothing is collected about you.

Make any sound move. RasterFX is a playable modular multi-effects processor for iPhone and iPad. Use it standalone with a microphone, an imported audio file or built-in signals — or load it as an AUv3 audio effect in AUM, GarageBand, Logic Pro for iPad, Loopy Pro, Cubasis and other Audio Unit hosts. BUILD YOUR EFFECT CHAIN Choose from Filter, Delay, Drive, Reverb, Grain, Repeat, Motion and Dynamics. Arrange up to six plates in series or split them into parallel A/B paths. Reorder the chain and the sound changes with it. MODULATE ANY CONTROL Patch LFOs, envelope followers, random and chaos sources, step sequencers, MIDI, macros, the XY pad or device tilt to any control. Create up to 16 modulation lines, with live arcs showing exactly how the sound is moving. PERFORM THE PATCH Morph between four snapshots on the XY pad. Turn eight macros. Hold four momentary throws for stutter, sweep, reverse and freeze. RasterFX is built to be played with one hand, not programmed and left alone. GENERATE, LOCK, EVOLVE Nudge a patch, reshape it or roll a new one. Lock the parts you want to keep, undo any result and save the seeds worth returning to. Evolve lets the patch drift over time while staying anchored to the sound you chose. SEE WHAT YOU HEAR Every effect has its own live visualizer. The CRT and halftone interface makes filters, delay taps, grains, dynamics and modulation visible without turning the screen into a wall of meters. RECORD THE RESULT Record the processed output to WAV, rename takes and share them from the app. FREE TO START. PRO ONCE. Free includes all eight effects, all modulation sources, every factory preset, three plates, four modulation lines and 60-second recordings. No ads, account, watermark or reduced audio quality. RasterFX Pro is a one-time purchase — not a subscription. It unlocks six plates, 16 modulation lines, split routing, XY snapshot morphing, Evolve, A/B compare, unlimited recording length and your own saved presets. Your saved sound always plays back exactly as created, even if it uses Pro features; Free limits editing, never playback. Made for headphones, late at night.
