No valves. Stainless steel reeds. The NONSLIDER brings blues harp expressiveness — bends, overblows, dynamic playing — to a fully chromatic instrument, in one of the most robust and maintenance-free harmonica designs ever built. SlideFree Companion is built for exactly this instrument. Instantly see how your chords and scales map across the NONSLIDER's double-row layout. Every blow, every draw, upper row, lower row. Right on your screen. The same way the NONSLIDER puts the full chromatic range at your fingertips, SlideFree Companion puts the full harmonic landscape in front of your eyes. Want to know what a G minor 7 chord looks like on your NONSLIDER? Two dropdown menus and you're there. Playing a jam and don't know the key of the song? Light up a scale and see every note mapped across your iPad or iPhone in an instant. On stage and need a quick reference? SlideFree Companion was designed for dark venues and real gig pressure — large, readable, fast. Trying to figure out if a C major or C7 fits better over that chord change? Switch between them in one tap while the song plays — and listen. Want to hear how a scale actually sounds before you play it? The app plays it through your speaker — ascending, descending, continuously — while your backing track runs in the background. A great musician never stops exploring. Neither should their tools. What's inside: 15 chords and 16 scales Chord and scale reference for Solo-Tuning NONSLIDER harmonicas in C, D, G, A, Bb, Low C, Low D, Low E and Low F All 15 major keys represented Three octave ranges MY HARP transposition — set your harp's key, every map updates instantly Built-in sequencer to hear any chord or scale played back Adjustable playback speed (BPM) and volume Version 1.2 adds multi-language musical notation. Switch between International (A B C), French (La Si Do), and German (A H C) note names with a single tap. A dot indicator below each flag shows which notation system is active. Optimized for iPhone and iPad in landscape No subscription. No ads. No frills. One purchase, yours forever. SlideFree Companion has exactly what you need and nothing you don't. That's not a limitation — that's the design and your device won’t go to sleep in the middle of the show either. Why? Because the show must go on. Not affiliated with or endorsed by C.A.
