FEATURES: • Stand-by mode to reduce battery usage or freeze the display. • Guided Mode Tuning offers an alternate strobe display that slows the strobe bands one-by-one as you come closer to tune. • Speed control for strobe display; dampen the response for a longer note display. • 12 Temperaments with adjustable root control. • Display all sharps note display. • Assisted Low Note Detection (ALND) helps capture very low frequencies. • Mains hum filter option reduces the chances of the tuner latching on to 50 or 60Hz cycle hum when using a direct line-in connection or while using the app during device charging. • Smooth, real-time strobe display allows you to achieve an unmatched level of accuracy. • Note/Octave window displays the correct note and octave for the note being tuned. • Cents display allows you to see how far out of tune your note is in cent values. • Tune in auto or manual mode. • Toggle the display to show: cents, Hz, MIDI note value for the note being tuned. • Glowing flat/sharp indicators assist when tuning a note very far from the target position. • Noise filter: Use the noise filter when utilizing an external mic or clip-on tuning device to help reduce the effect of extraneous environmental noise during tuning. • Input boost: The input boost will raise all input frequencies by +24dB. • Calibration mode: iStroboSoft can be calibrated to an external source guaranteeing 1/10th cent accuracy. • Drop/Capo mode: iStroboSoft will auto-transpose notes up or down to one full octave. • Adjustable Concert A: Change the Concert A reference of the tuner to accommodate tuning to a fixed instrument, such as a piano, or tune instruments that do not utilize the typical Western A440 reference. • Full screen mode permits the strobe display to be maximized on screen to allow better viewing from a distance. • Change strobe display colors to accommodate different lighting environments or set a preferred user color for those with limited color palette recognition. Use the built-in mic on your device for tuning or connect directly via the headphone jack using an approved adaptor cable or interface. Devices without a headphone jack can connect a pickup or mic using the lightning-to-audio adaptor. Support via email at: info@strobosoft.com or call 708.388.3311 M-F 8am-5pm (CST)

You know the theory. You just have to look it up. Scale Theory is a drill tool for musicians who want faster, more reliable recall — key signatures, diatonic harmony, modes, chord functions, and relative minor relationships. Not slower. Not effortful. Just known. What you'll learn: • Key signatures: sharps, flats, and which notes they are, in both directions • Relative minor keys, quizzed both ways • Diatonic triads and seventh chords in every major key — names, qualities, and notes • All seven modes: names, interval formulas, and characteristic chords • Chord functions: identify and spell the dominant seventh and half-diminished chord in any key How it works: Each topic follows a review-then-quiz loop. New items are revealed one piece at a time, so you're predicting the next step before it appears. After every few new items, a recap quiz covers everything learned so far — not just what's recent. A randomized Practice mode presents questions in mixed formats across all keys, with upcoming answers hidden so you can't read ahead. Key signatures follow circle-of-fifths order, which is how keys actually relate to each other. Who it's for: • Players who want to think faster when improvising or reading charts. • Anyone whose theory knowledge lives in their head in a slow, effortful way. • Students prepping for graded exams. This is a drill tool, not a lesson. It assumes you've encountered these concepts — it's here to make them automatic.
