Read full description

Plan not just what fits, but how it connects—before building your pedalboard. Design on iPhone and iPad at true scale, from pedal placement and signal flow to physical cable routes. Use landscape view and pinch zoom to select and edit cable runs. TRUE-SCALE LAYOUT AND SIGNAL FLOW • Set board and device dimensions in millimeters and drag devices into position • Add pedal photos and adjust jack positions and cable exit directions • Plan Guitar-to-Amp Signal Chains and switcher loops • Explore layout and signal order separately; share board images and wiring diagrams • Follow the first-board tutorial and illustrated routing guide FREE ON IPHONE AND IPAD Save one board with no pedal-count limit. Ads are shown, including a banner while editing the board. Rotation and advanced signal-flow tools require Pro or higher. Physical CAD and image-based opening registration require Signal Pro. PRO: MORE FLEXIBLE LAYOUTS AND SIGNAL FLOW • Remove ads, unlock unlimited saved boards, and duplicate boards • Use the built-in real-pedal database • Rotate pedals in 90-degree steps and place power supplies and junction boxes • Assign multiple pedals to a switcher loop and use TUNER OUT • Build Advanced Chains with junction channels and amp INPUT/SEND/RETURN Standard Pro does not include physical cable-routing CAD. SIGNAL PRO: ALL PRO FEATURES + PHYSICAL CABLE CAD • Edit openings, slots, rails, and underside structure in Board Structure • Detect suggested openings from a board image, review them, and confirm registration • Design physical signal and DC power cable routes in Cable Routing • Pass through an opening to the underside and return through another opening • Set plug shape, dimensions, cable diameter, and exit direction; reuse named plug presets • Check designed route length, plug passage, and underside clearance • Export underside routing as a PNG image Image detection proposes candidates, not guaranteed measurements. Use a near-overhead image with clear opening/background contrast and verify positions and dimensions against the actual board. Cable lengths are design calculations; allow for real-world construction. PLANS AND ACCESS Pro and Signal Pro are auto-renewable subscriptions with monthly and annual options. Signal Pro includes Pro; you do not need both subscriptions. Restore purchases with the same Apple Account to use your plan on iPhone, iPad, and Mac. This does not provide automatic board-data sync. See the purchase screen for price, duration, and eligible introductory offers. Payment is charged to your Apple Account at confirmation. Subscriptions renew automatically unless canceled at least 24 hours before the period ends. Manage or cancel in your App Store account settings. Saved data is not deleted when a subscription ends. Editing paid features and boards beyond the free saved-board limit is restricted. Previous lifetime purchases can be restored for ad removal and three saved boards; they do not unlock all Pro or Signal Pro features.

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.
