Read full descriptionHide full description
Which patch was that again? What's this one even for? — Every multi-effects user knows the struggle. PatchMemo GX puts an end to "patch confusion." PatchMemo GX is a companion app for recording and managing your BOSS GX-1 patch settings. The official app shows you a list of patch names, but names alone aren't enough to remember what's what. Record your effect chains, gear setups, notes, and tags — and instantly find "that sound you made that time." ◆ Patch Management Supports all user patches from U01 to U99. Record settings for every effect block: PREAMP/CAB, OD/DS, FX1–3, DELAY, REVERB, and more. ASSIGN matrix notes included. Tags and search help you find any patch in seconds. ◆ Setlists Log the order of patches used for each gig or practice session. Look back anytime to see "what did I use at that show?" ◆ Library A unique feature that lets you save your favorite amp + cabinet combinations as Rigs. You can also record guitar, pickup, and output routing combinations. Load them as templates into patches to speed up your workflow. ◆ Anytime, Anywhere No Bluetooth or cable connection needed. View and edit your patch info on your phone — at the studio, at home, or on the go. ◆ More ・5 languages (日本語・English・Deutsch・한국어・Português) ・Dark mode UI ・Fully offline (no cloud required) ・All data stored on your device Privacy Policy: https://dev.nishimoto-learning.jp/apps/patchmemogx/privacy Terms of Use: https://dev.nishimoto-learning.jp/apps/patchmemogx/terms This app is not affiliated with or endorsed by Roland Corporation.

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.
