Knob Lab vs Timecode Tool App

Knob Lab turns your iPhone or iPad into a MIDI controller built around one idea: a single knob can do many things at once. ONE KNOB. MANY MOVES. Map a knob to up to 8 MIDI destinations. Each has its own range, direction, channel and colour, so one turn can open a filter, pull the resonance back and bring the delay in over the second half of the sweep. BUILD YOUR OWN MACROS • Control Change, Program Change and Pitch Bend destinations • Name every knob and every destination, so a setup reads at a glance • Invert any range, or start a destination part-way through the turn • Rotate completely, snap to middle, pan left/right, or return to origin on release • A coloured lane for every destination shows where each one is A LAYOUT FOR EVERY SETUP Start with one big knob, or unlock layouts with 2, 6 or 12 knobs on a single screen. PLAYS WITH EVERYTHING • Music apps on the same device, through Knob Lab's virtual MIDI output • Computers over Wi-Fi, with a network MIDI session • A Mac over USB or Bluetooth, with Sonic Logic Central • Class-compliant USB MIDI interfaces and synths plugged into your iPhone or iPad MADE FOR TOUCH Large, precise knobs, a quick guided start, and Dark, Light and Neon themes. The one-knob layout is free. The 2, 6 and 12 knob layouts are in-app purchases, available one at a time or all together.

Timecode Tool is a focused utility for live-show technicians who need to generate, monitor, convert, measure or calculate SMPTE timecode on iPad, iPhone, and Apple Silicon Mac. Five tools: GENERATE • Output LTC audio and Art-Net Timecode driven by system time-of-day, a free-running 1-hour block, or a custom Start Timecode you type in (e.g. 02:03:20:15) that free-runs from that point. • A media-player transport while running — previous block, back to start of block, play/pause, next block. (Hidden for time-of-day, which follows the wall clock instead of a block you can skip through.) • Pick FPS (24, 25, 29.97 NDF, 29.97 DF, 30) including correct SMPTE drop-frame counting. • Send to a specific Art-Net destination IP (unicast or broadcast). MONITOR • A large, glanceable timecode readout for monitoring. • Choose the source: decode LTC from an audio input, or receive Art-Net Timecode over the network. Frame rate and lock state are shown live. CONVERT • Route one timecode input to up to two simultaneous outputs, freely chosen: input is LTC audio, Art-Net, or MTC; each output is LTC audio, Art-Net, or MTC. • MTC: Timecode Tool publishes a virtual MIDI port, "Timecode Tool", that shows up as a MIDI input in every other app on your device — your DAW can chase it with no cable or MIDI interface. Output can also go to a real MIDI destination, and input can come from any MIDI source. • Warns up front about setups that would misbehave: Art-Net in and out sharing a UDP port, LTC in and out on the built-in speaker and mic, and MTC feeding back into itself. • Latency compensation per output, with drift tracking and a re-sync control. Auto-detects the source frame rate and the drop-frame flag, with an override for 29.97 non-drop versus 30 fps. MEASURE • A delay checker. Tap the pad twice — or keep tapping along to a beat — and read the interval in milliseconds, frames at the rate you choose, timecode, BPM, seconds, or audio samples. • Then hear it: two clicks exactly that far apart, a click every interval, or your own taps replayed, placed on the audio clock to the sample. • A tap far from the others — a double tap, a missed beat — is flagged as it lands and left out of the statistics. Save a measurement with its taps, rate and statistic, and bring it back later. • Last, average, min, max and jitter at a glance; every unit has Copy. CALCULATE • A timecode calculator. Add, subtract, multiply and divide timecode, frames, seconds, milliseconds and h:mm:ss clock time in any mix — for example "01:03:40:15, one minute thirty-five later". • Pick each operand's unit on a sliding switch under the field. Shorthand accepted: 95s, 1500ms, 1m35s, 40f, or just digits into a timecode field. Paste into any field; the unit follows the text. • A sentence above the result says what was done — "Added 1 min 35 s to timecode 01:03:40:15" — and the result appears in every form at once, each with its own Copy, chaining back into the next calculation. Drop-frame arithmetic uses the same frame counting as the generator. • Measure and Calculate also work at 59.94 and 60 fps. Cross-cutting features: • Background audio — keeps generating / decoding when the screen is locked or another app is foreground. • Phone calls and Siri don't break the timecode stream; it resumes. • Shows your device's IP addresses. Works with Class-Compliant USB audio interfaces. Available in English, Japanese, Korean, Simplified Chinese, French and German. Timecode Tool does not collect, store, or transmit any personal data.
